During the last stage of the menstrual cycle, normally a layer of endometriosis lining on the inside of the uterus is expelled, known as menstruation blood. Instead, some of the endometriosis tissues grow somewhere in the body to cause endometriosis. Endometriosis also react to hormone signals of the monthly menstrual cycle, by building and breaking up tissues and eliminating them through menstrual period.
Prostaglandins inhibitors are men made prostaglandins hormones helped to block the production of prostaglandins(6) from our body during menstrual cycle. Over production of certain types of prostaglandins hormones cause of over contraction of uterine muscles may result in menstrual cramps. Blocking them are benefits for women with severe period pain.
I. The effectiveness
a) Inhibiting the natural prostaglandins in the women menstrual cycle will reduce the over active uterine and ovarian muscles that cause the abdominal pain(1)(2), if endometrial implants and adhesion in the wall of the ovary.
b) The medication can be brought without prescription, such as flufenamic acid, ibuprofen and naproxen(2)(3), etc.
c) They also help to reduce the heavy period(2)(3) as uterine muscles now are being controlled by the effects of the medication.
d) They are more effective in treating symptoms of menstrual cycle(4)(5) if taking together with other oral contraceptive pills.
e) They sometime may also correct the prostaglandins imbalance(6) for some women.
f) Reduced menstrual fluids(2)(3).
2. Risks
a) Most prostaglandins inhibitors only correct the symptoms while they are around. Symptoms of menstrual cycle will re appear when the medication is wire off.
b) Over taking porstaglandins inhibitor will severely damage the liver(8), causing variety of diseases(7).
c) The medication may cause gastro-intestine system problem(9), such as stomach pain, vomiting, nausea, constipation. Taking them with foods can reduce the above side effects.
d) Increase the risk of asthma(10), lupus(11) and clotting disorders(12).
e) They may cause intrauterine infection(13).
3. Side effects(9)(14)
It is advised that prostaglandins inhibitors drugs should be taken with food to prevent any problem with the gastro-intestine system. Since prostaglandins inhibitors are nonsteroidal anti-inflammatory drug, they have below side effects if overdose.
1) Nausea
2) Vomiting
3) Stomach pain
4) Micro-bleeding and ulcers
5) Abdominal cramps.

Skin aging is one of the most visible aging processes that occur constantly in our skin. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, and affect skin elasticity and tightness (a). Another study suggested that free radicals induced domino effects in production of reactive oxygen species and can react with DNA, proteins, and fatty acids causing oxidative damage and impairment of the antioxidant system, leading to injuries, damage of the regulation pathways of skin causing wrinkles, roughness, appearance of fine lines, lack of elasticity, and de-pigmentation or hyperpigmentation marks (b). Walking through the drug and commercial cosmetic stores, one can see hundreds of anti-aging creams and products displayed. Many of them have also gone through certain studies for its efficacy with advertisement through media and celebrities. In fact, according to statistics, Global Anti-Aging Products Market will be worth $291.9 Billion by 2015. Searching through the key word of Dehydroascorbic Acid (Oxidized Vitamin C, DHAA) and skin has yielded no related studies or clinical trials. It may be the result of the solution having no commercial value as it can be made by any cosmetic purchaser, or the studies indicate that L-ascorbic acid must be formulated at pH levels less than 3.5 to enter the skin with maximal concentration of 20% for optimal percutaneous absorption. But according to Dr. Douglas Q. Kitt, Dehydroascorbic Acid (DHAA) permeates stratum corneum at a rate up to 12 times faster than AA. This supports the concept that lower concentrations of DHAA in topical preparations can enhance skin vitamin C levels with less potential side effects (c).
A. Dehydroascorbic Acid (DHA) (vitamin C supplement oxidized form)
The Chemical Reaction and Structure
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin found in fresh fruits, berries and green vegetables. It is best known for its free radical scavenging activity and regenerating oxidized vitamin E for immune system support. In skin aging, the vitamin may improve solar radiation protection and epidermal aging (1) through production of collagen due to its antioxidant activity (2)(3). Epidemiological studies linking vitamin C in prevention of skin damage and aging have produced some certain results (3a)(3b)(3c), but the large sample size and multi-centred studies are necessary to validate its effectiveness. Vitamin C oxidized form or dehydroascorbic acid (DHA) processed antiviral and virucidal effects (23) showed to prevent H2O2-induced cell death by increasing the GSH levels mediated by the GPx and GR activities and PPP (17), and regulated neuronal energy metabolism, through facilitating the utilization of glucose via the PPP for antioxidant purposes (18) by increasing antioxidant potential in the central nervous system (19). Dehydroascorbic acid (DHA) may be a potential anti-cancer agent to treat aggressive cancers (20)(21). Dr. Toohey at the Cytoregulation Research said "rapidly-dividing tumour cells make unusually large amounts of homocysteine thiolactone and that administered dehydroascorbic acid enters the cells and converts the thiolactone to mercaptopropionaldehyde which kills the cancer cells" (22).
B. Vitamin C
1. Plasma levels of vitamin C
L-ascorbic acid is known for its effects on skin-whitening and against the anti-oxidation causes of skin aging. During the aging process, levels of vitamin C was found to slowly deplete according to the Tokyo Metropolitan Institute of Gerontology in the measurement of plasma and urine of C57BL/6 male mice during 3 to 30 months of aging(4). Therefore, restoration of physiological levels of vitamin C inside the cells might improve the lysosomal degradation (protection of cell from the degradative enzymes through protection of the cytosol) in the outflow pathway cells and prevent the pathogenesis of glaucomadegrade proteins(5). Unfortunately, some researchers suggested that higher levels of circulating vitamin C may not provide protection against incident radiographic knee OA, and be associated with an increased risk of knee OA(6) and the 1Panorama Research Institute and Regenerative Sciences Institute, insisted "careful attention to individual and family medical history and personal genomic data may prove essential to make wise dietary and supplement choices to be combined with exercise”(7).
2. The effects According to the Minghsin University of Science and Technology, in doses of a dependent manner, the concentration of L-ascorbic acid induced absorption of the collagen solution in exhibition of smoothing wrinkles and clear up spots(8). Ascorbic acid (AA) is essential in stimulating collagen gene expression. In type 1 and type 4 collagen and SVCT2, the vitamin was found to enhance the expression of type 1 and type 4 collagens and SVCT2 mRNA in cultured human skin fibroblasts at 100 μM AA placed every 24h for 5 days to prevent depletion(9). The Chiang Mai University study also supported the effects of ascorbic acid in the anti-aging process through exhibition pro and active MMP-2 inhibitory(10). Other studies suggested the combined vitamins, including vitamin C in a single formulation had a slightly lower degradation rate and more stable formulations as compared to different preparations containing only one of the vitamins(11)(12). Amazingly, in vivo, application of vitamin C showed a significant reduction of oxidative stress in the skin, an improvement of the epidermal-dermal microstructure and a reduction of fine lines and wrinkles in aged skin within a relatively short period of time of product application(13). The Bruce and Associates study also insisted the effectiveness of vitamin C application over a 12 week period as the vitamin enhanced the overall intensity of pigmentation, fine lines and wrinkles, tactile roughness, and laxity with a 100% satisfaction of overall appearance of the tested subjects’ skin(14).
1. Skin roughness and Scaliness
Skin roughness due to aging is a result of dead skin cells shedding more slowly, and building up in the upper layer of skin causing skin complexion to become rough and dull. According to the University of California at San Francisco, they are the result of aging and anatomic site of which demonstrated a significant influence on skin roughness and scaliness(25). Another study suggested that frictional properties of skin are dependent on more than water content or non-apparent sweating and the role of sebum secretion may be one possible factor(26), or it may be result of depletion of surface lipid content(27).
2. Wrinkles
Wrinkles are also associated with aging, hormonal status, smoking, and intercurrent disease according to the study by the University of California-San Francisco(28). Some researchers suggested that vitamin C may play an important role in collagen production due to its antioxidant properties(28). Another study indicated a positive anti-wrinkle effect through consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E, and fish oil(29).
3. Skin elasticity and firming
Skin sagging is a result of a loss of collagen and elastin of the skin due to aging in combination with the dreaded pull of gravity. The study of a novel dietary supplement (Imedeen Prime Renewal) including soy extract, fish protein polysaccharides, extracts from white tea, grape seed and tomato, vitamins C and E as well as zinc and chamomile extract, showed to inhibit forehead, periocular and perioral wrinkles, mottled pigmentation, laxity, sagging, under eye dark circles, and overall appearance. After 6 months treatment, it was suggested that the formula may provide improved condition, structure and firmness of the skin in post-menopausal women(30). Other studies insisted that since vitamin C (Vit. C) in the form of L-ascorbic acid (Asc) can accelerate wound healing(33)(32) and protect fatty tissues from oxidation damage(33), it may play an integral role in collagen synthesis of reducing wrinkles and skin sagging(34)(35)
4. Liver and aging spots
Liver spot is a condition of brown or black spots appearing on the surface of the skin due to aging and exposure to ultraviolet radiation from the sun. According to skin care guides, high concentration of Vitamin C may improve the skin and lighten the spots(36). Other articles insisted that liver spots may be the result of a deficiency of vitamin C(37). According to the Duke University Medical Center, the application of topical solutions containing vitamins C and E provided protection for human skin against damage caused by ultraviolet radiation(38)(39)(40)(41).
5. Pigmentation
Skin pigmentation disorder is a result of damage most likely caused by UV sunlight, or unhealthy cells due to aging affecting the production of melanin. Vitamin C topical and by iontophoresis are found effectively in aiding post-laser hyperpigmentation or short and long term treatment (42) for melism (43). In an experiment where 29 females with melisma enrolled for iontophoresis, a vitamin C solution was applied to one side of the face, while distilled water was applied to the other side as a control, treatment with colorimeter site showed a significant decrease in the luminance value, (a photometric measure of the luminous intensity per unit area of light) compared to that of the control site (44).
6. Acne and Acne scars
According to Dr. GEORGE E. MORRIS, M.D., in a study of 60 patients with acne being given 8 oz of citrus juice twice daily and vitamin C in 3 gm a day, after 4 months 43 showed improvement, 10 failed to show improvement and 7 did not return for follow up(45). Some articles showed that vitamin C may be effective in the reduction of the formation of acne scars through it’s anti-inflammatory and free radical scavenger activities(46), but no study has been found through searching on PubMed.
7. Back and White heads
Black and white heads are the result of a skin pore becoming clogged with sebum from the body's natural oil and becoming black heads if oxidized. No study has been found specifically for the key word vitamin C and back and white heads on PubMed.
8. Fine Lines
No study and been found.

Skin aging is one of the most visible aging processes that occur constantly in our skin. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, and affect skin elasticity and tightness (a). Another study suggested that free radicals induced domino effects in production of reactive oxygen species and can react with DNA, proteins, and fatty acids causing oxidative damage and impairment of the antioxidant system, leading to injuries, damage of the regulation pathways of skin causing wrinkles, roughness, appearance of fine lines, lack of elasticity, and de-pigmentation or hyperpigmentation marks (b). Walking through the drug and commercial cosmetic stores, one can see hundreds of anti-aging creams and products displayed. Many of them have also gone through certain studies for its efficacy with advertisement through media and celebrities. In fact, according to statistics, Global Anti-Aging Products Market will be worth $291.9 Billion by 2015. Searching through the key word of Dehydroascorbic Acid (Oxidized Vitamin C, DHAA) and skin has yielded no related studies or clinical trials. It may be the result of the solution having no commercial value as it can be made by any cosmetic purchaser, or the studies indicate that L-ascorbic acid must be formulated at pH levels less than 3.5 to enter the skin with maximal concentration of 20% for optimal percutaneous absorption. But according to Dr. Douglas Q. Kitt, Dehydroascorbic Acid (DHAA) permeates stratum corneum at a rate up to 12 times faster than AA. This supports the concept that lower concentrations of DHAA in topical preparations can enhance skin vitamin C levels with less potential side effects (c).
A. Dehydroascorbic Acid (DHA) (vitamin C supplement oxidized form)
The Chemical Reaction and Structure
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin found in fresh fruits, berries and green vegetables. It is best known for its free radical scavenging activity and regenerating oxidized vitamin E for immune system support. In skin aging, the vitamin may improve solar radiation protection and epidermal aging (1) through production of collagen due to its antioxidant activity (2)(3). Epidemiological studies linking vitamin C in prevention of skin damage and aging have produced some certain results (3a)(3b)(3c), but the large sample size and multi-centred studies are necessary to validate its effectiveness. Vitamin C oxidized form or dehydroascorbic acid (DHA) processed antiviral and virucidal effects (23) showed to prevent H2O2-induced cell death by increasing the GSH levels mediated by the GPx and GR activities and PPP (17), and regulated neuronal energy metabolism, through facilitating the utilization of glucose via the PPP for antioxidant purposes (18) by increasing antioxidant potential in the central nervous system (19). Dehydroascorbic acid (DHA) may be a potential anti-cancer agent to treat aggressive cancers (20)(21). Dr. Toohey at the Cytoregulation Research said "rapidly-dividing tumour cells make unusually large amounts of homocysteine thiolactone and that administered dehydroascorbic acid enters the cells and converts the thiolactone to mercaptopropionaldehyde which kills the cancer cells" (22).
B. Vitamin C
1. Plasma levels of vitamin C
L-ascorbic acid is known for its effects on skin-whitening and against the anti-oxidation causes of skin aging. During the aging process, levels of vitamin C was found to slowly deplete according to the Tokyo Metropolitan Institute of Gerontology in the measurement of plasma and urine of C57BL/6 male mice during 3 to 30 months of aging(4). Therefore, restoration of physiological levels of vitamin C inside the cells might improve the lysosomal degradation (protection of cell from the degradative enzymes through protection of the cytosol) in the outflow pathway cells and prevent the pathogenesis of glaucomadegrade proteins(5). Unfortunately, some researchers suggested that higher levels of circulating vitamin C may not provide protection against incident radiographic knee OA, and be associated with an increased risk of knee OA(6) and the 1Panorama Research Institute and Regenerative Sciences Institute, insisted "careful attention to individual and family medical history and personal genomic data may prove essential to make wise dietary and supplement choices to be combined with exercise”(7).
2. The effects According to the Minghsin University of Science and Technology, in doses of a dependent manner, the concentration of L-ascorbic acid induced absorption of the collagen solution in exhibition of smoothing wrinkles and clear up spots(8). Ascorbic acid (AA) is essential in stimulating collagen gene expression. In type 1 and type 4 collagen and SVCT2, the vitamin was found to enhance the expression of type 1 and type 4 collagens and SVCT2 mRNA in cultured human skin fibroblasts at 100 μM AA placed every 24h for 5 days to prevent depletion(9). The Chiang Mai University study also supported the effects of ascorbic acid in the anti-aging process through exhibition pro and active MMP-2 inhibitory(10). Other studies suggested the combined vitamins, including vitamin C in a single formulation had a slightly lower degradation rate and more stable formulations as compared to different preparations containing only one of the vitamins(11)(12). Amazingly, in vivo, application of vitamin C showed a significant reduction of oxidative stress in the skin, an improvement of the epidermal-dermal microstructure and a reduction of fine lines and wrinkles in aged skin within a relatively short period of time of product application(13). The Bruce and Associates study also insisted the effectiveness of vitamin C application over a 12 week period as the vitamin enhanced the overall intensity of pigmentation, fine lines and wrinkles, tactile roughness, and laxity with a 100% satisfaction of overall appearance of the tested subjects’ skin(14).
1. Skin roughness and Scaliness
Skin roughness due to aging is a result of dead skin cells shedding more slowly, and building up in the upper layer of skin causing skin complexion to become rough and dull. According to the University of California at San Francisco, they are the result of aging and anatomic site of which demonstrated a significant influence on skin roughness and scaliness(25). Another study suggested that frictional properties of skin are dependent on more than water content or non-apparent sweating and the role of sebum secretion may be one possible factor(26), or it may be result of depletion of surface lipid content(27).
2. Wrinkles
Wrinkles are also associated with aging, hormonal status, smoking, and intercurrent disease according to the study by the University of California-San Francisco(28). Some researchers suggested that vitamin C may play an important role in collagen production due to its antioxidant properties(28). Another study indicated a positive anti-wrinkle effect through consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E, and fish oil(29).
3. Skin elasticity and firming
Skin sagging is a result of a loss of collagen and elastin of the skin due to aging in combination with the dreaded pull of gravity. The study of a novel dietary supplement (Imedeen Prime Renewal) including soy extract, fish protein polysaccharides, extracts from white tea, grape seed and tomato, vitamins C and E as well as zinc and chamomile extract, showed to inhibit forehead, periocular and perioral wrinkles, mottled pigmentation, laxity, sagging, under eye dark circles, and overall appearance. After 6 months treatment, it was suggested that the formula may provide improved condition, structure and firmness of the skin in post-menopausal women(30). Other studies insisted that since vitamin C (Vit. C) in the form of L-ascorbic acid (Asc) can accelerate wound healing(33)(32) and protect fatty tissues from oxidation damage(33), it may play an integral role in collagen synthesis of reducing wrinkles and skin sagging(34)(35)
4. Liver and aging spots
Liver spot is a condition of brown or black spots appearing on the surface of the skin due to aging and exposure to ultraviolet radiation from the sun. According to skin care guides, high concentration of Vitamin C may improve the skin and lighten the spots(36). Other articles insisted that liver spots may be the result of a deficiency of vitamin C(37). According to the Duke University Medical Center, the application of topical solutions containing vitamins C and E provided protection for human skin against damage caused by ultraviolet radiation(38)(39)(40)(41).
5. Pigmentation
Skin pigmentation disorder is a result of damage most likely caused by UV sunlight, or unhealthy cells due to aging affecting the production of melanin. Vitamin C topical and by iontophoresis are found effectively in aiding post-laser hyperpigmentation or short and long term treatment (42) for melism (43). In an experiment where 29 females with melisma enrolled for iontophoresis, a vitamin C solution was applied to one side of the face, while distilled water was applied to the other side as a control, treatment with colorimeter site showed a significant decrease in the luminance value, (a photometric measure of the luminous intensity per unit area of light) compared to that of the control site (44).
6. Acne and Acne scars
According to Dr. GEORGE E. MORRIS, M.D., in a study of 60 patients with acne being given 8 oz of citrus juice twice daily and vitamin C in 3 gm a day, after 4 months 43 showed improvement, 10 failed to show improvement and 7 did not return for follow up(45). Some articles showed that vitamin C may be effective in the reduction of the formation of acne scars through it’s anti-inflammatory and free radical scavenger activities(46), but no study has been found through searching on PubMed.
7. Back and White heads
Black and white heads are the result of a skin pore becoming clogged with sebum from the body's natural oil and becoming black heads if oxidized. No study has been found specifically for the key word vitamin C and back and white heads on PubMed.
8. Fine Lines
No study and been found.

Some articles have been used as references in medical research, such as international journal Pharma and Bio science, ISSN 0975-6299.
During the last stage of the menstrual cycle, normally a layer of endometriosis lining on the inside of the uterus is expelled, known as menstruation blood, instead some of the endometriosis tissues grow somewhere in the body to cause endometriosis. Endometriosis also react to hormone signals of the monthly menstrual cycle, by building and breaking up tissues and eliminating them through menstrual period.
GnRH is a hormone released by the hypothalamus which stimulates the pituitary to produce luteinising hormones (LH) and follicle that stimulate hormone (FSH) to drive a menstrual cycle.
1. Effectiveness of GnRH
Just likes progesterone-like agonists, GnRH ( gonadotrophin-releasing hormone) have been used in treating endometriosis for more than 20 years. They come in different forms: three-monthly injection, monthly injection, daily injection and nasal spray because of their chemical make up. GnRH are natural hormone blocking medicines, they help to stop the ovulation(2) and create a temporary menopause state(2).
Study shows that GnRH are effective in reducing the symptoms such as pain and infertility. Dysmenorrhoea, deep dyspareunia, dyschezia and dysuria(1) and the size of endometrial implants(1) but unfortunately, symptoms tend to return(3) after stopping treatment in 4 months.
2. Side effects
a) Hot flush, interruption of sleep (4), dry vagina(5), sweating(5), caused by temporary of menopause state.
b) Nutritional deficiency(7) caused by symptoms of menopause state as our body is no longer absorb magnesium and calcium effectively.
ce) Bleeding (spotting, break-through bleeding, menstruation)(5)
3. Risks
1. Loss of bone density(6)
Loss of bone density is normal for women taking the GnRH drug. Since it causes menopause state, it deplete the calcium in the body that is essential for building a healthy bone. It also distorts the ratio of magnesium and calcium.
2) Reducing sexual desire(5)
Sexual libido may be caused by dry vagina, one of many symptoms of GnRH. It may also be caused by low level of estrogen that is essential for driving sexual desire.
3) Increase the risk of ectopic pregnancy(8).
4) Diminished ovarian reserve(9).

During the last stage of the menstrual cycle, normally a layer of endometriosis lining on the inside of the uterus is expelled, known as menstruation blood, instead some of the endometriosis tissues grow somewhere in the body to cause endometriosis. Endometriosis also react to hormone signals of the monthly menstrual cycle, by building and breaking up tissues and eliminating them through menstrual period.
The oral contraceptive pill is defined as one type of birth control pill containing both estrogen and progesterone that helps to control unwanted pregnancy and reducing symptoms of abdominal pain before, during or after menstrual cycle such as endometriosis, premenstrual symptoms etc.
The pill is taken 21 days on, 7 day off.
1. The intention
a) It will help to reduce the bleeding by thinning the endometrial lining and reducing the flow of the period blood that help to decreases the risk of retrograde menstruation in endometriosis.
b) It also helps to inhibit hormone prostaglandins that causes muscle spasm in the ovary reducing the menstrual cramps(5)(7).
c) Since the pill reduces the heavy bleeding(6) of endometriosis, it is lesser the risk of bleeding into cysts and pelvic cavity.
d) Managing the endometriosis(8) by creating a continual pregnant-like state.
e) Reduced menstrual symptoms, such as headaches, genital irritation, tiredness, bloating(7).
2. Risks and side effects
a) Risks
i) Since the oral contraceptive combination pill contains estrogen, it may cause blood clots(3), stroke(3), heart disease(1) and induced breast cancer(2)
ii) Hypertension(1) and increase heart rate(1) caused by thickening of blood in arteries.
b) Side effects
i) Bleeding and spotting(4) as our body needs time to adjust to the substance in the pill, Normally, the bleeding and spotting will end in six months.
ii) Weigh gain(9)(10)(11)(inconclusive result) caused by synthetic progesterone in the pill in some women.
