I have truly believed that scientists have found a natural ingredient for define-aging, but it was shelved as it offers no commercial value. If one is published with effectiveness more superior than the currently sold products, it may be a death spell to many companies which rely totally in selling cosmetic products.
Anti-aging and maintaining our youthful appearance has been researched throughout human civilization. Today, these researchers have become more aggressive as finding a workable agent may produce billions of dollars of profits to the found company. According to statistics, Global Anti-Aging Products Market will reach $291.9 Billion by 2015.
Dehydroascorbic acid (DHA)(*) 12% concentration may be a potent solution in regained the youthfulness of forearm between the wrist and elbow in stimulated reproduction of collagen against Skin sagging due to aging progression.
Abstract
Introduction
Skin aging is one of the most visible ageing processes that occur constantly in our skin organ. Many ingredients from synthetic and natural sources have been proven in studies to have certain effects on skin aging. In our previous study, Dehydroascorbic acid (DHA) at 4% showed a significant improvement in smoothing of the skin, skin elasticity, firming, disappearance of black and white heads, liver spots, pigmentation, and healing acne and acne scars. In this study, Dehydroascorbic acid (DHA) at 12% is tested for its effectiveness in stimulated reproduction of collagen in the forearm between the wrist and elbow.
Method of Experimentation
10 Patients at age 59 -60 (5 females and 5 males; 5 Caucasians, 3 Asians and 2 Africans) were recruited to test for aging process due to loss of collagen causes of skin sagging in the forearm (left or right) between the wrist and elbow.
Patients must also agree during the study that they will not to use any other topical products (such as including moisturizers, sunscreens, and fragrances, make-up and any facial procedures such as peels, facials, microdermabrasion, and injection of botulinum toxin type A or dermal fillers) but the testing solution. The study also examines the patient with any cosmetic surgery and/or medication use of which may interfere with the study, as well as history of facial skin diseases. All patients are also required to sign an informed consent. Solutions of Dehydroascorbic acid (DHA)(*)were remixed every 3 days in order to maintain their refreshness and concentration levels.
Patients were instructed to stir the solution well with wooden chopstick or ice cream stick and wear glove when apply the solution to prevent oxidation causes of brownness in the palm and figure nails due to high concentration of the solution, as well as to cover the applied areas before going out to extreme sunlight.
Patients were also instructed to apply the provided solution on their forearm between the wrist and elbow for a duration of 12 weeks. Forearm up to the wrist examinations were conducted and recorded every 4 weeks.
Results
All patients completed the trial. Topical administration of Dehydroascorbic acid (DHA)(*) 12% showed to stimulate the reproduction of collagen in enhancing the youthfulness of the applied area up to 95% in 4 patients
Conclusion
Treatment of concentrations of Dehydroascorbic acid (DHA)(*) at 12 % exhibited a significant efficacy in rejuvenation of the youthfulness of forearm between the wrist and elbow through reproduction of collagen skin smoothing, elasticity, firming, probably through anti-inflammatory and skin absorption pathways, in doses, skin aging progression and durative depending manner. It may be used to rejuvenate the skin in other parts of the body. Since the experimental group is small in nature, further studies with a larger sample size are necessary to improve the ingredient’s validation.

Introduction
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).
Dehydroascorbic Acid (DHA) (vitamin C supplement oxidized form)
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).
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)
5. 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).
6. 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).
8. 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.
9. 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.
10. Fine Lines
No study and been found.
Method
A total of 10p atients were recruited with ages ranging from 59 - 60 (5 Caucasians, 3 Asians and 2 Africans, and 5 females and 5 males) to test for the effectiveness in the difference of concentrations of Dehydroascorbic acid (DHA) at 12% ( 24000mg diluted into 100 mL of hot water which is let cool before refrigerating).
Patients are eligible to enter this study
Selection was based on those who had moderate to severe forearm wrinkles. Patients must also agree during the study that they will not to use any other topical products but the testing solution, such as moisturizers, sunscreens, fragrances, make-up, and any facial procedures such as peels, facials, microdermabrasion, and injection of botulinum toxin type A or dermal fillers. The study also examines the patient with any cosmetic surgery and medication use which may interfere with the study, as well as history of facial skin diseases. All patients are also required to sign an informed consent.
Patients were instructed to stir the solution well with wooden chopstick or ice cream stick and wear glove when apply the solution to prevent oxidation causes of brownness in the palm and figure nails due to high concentration of the solution, as well as to cover the applied areas before going out to extreme sunlight.
Patients were also instructed to apply the provided solution on their forearm up to the wrist for a duration of 12 weeks. Facial skin examinations were conducted and recorded every 4 weeks.

As the data indicates, patient satisfaction with the solution and the progression of skin sagging reduction.
Tolerability
Through over 12 weeks of application with the designed solution, no adverse effect has been reported in the group.
Discussion
Dehydroascorbic acid (DHA)(*) showed the most efficacy in enhanced smoothness, firmness, and elasticity of the skin through stimulation the production of collagen on forearm between the wrist and elbow, probably through its antioxidant activities via inflammatory pathways, and skin absorption property. It may be used in other parts of the body including facial skin.
The efficacy of the solutions indicated a logical thinking through maintaining healthy skin by preventing the loss of collagen due to aging is the most effective way to slow down the aging progression. Dehydroascorbic acid (DHA)(*) at 12% concentration may provide us with more insight with this astonished result, but further study is necessary to rule out any adverse effect and improve its validation, due to small sample size.
Please make sure that you discuss the use of any topical solution in the study with your doctor or related field specialist before applying. Please Donate for funding the larger sample size study to improve the validation of this discovery.
