Moderate intake of caffeinated coffee regularly may have a particular effect in protecting the skin against aging, a joint institutes study suggested.
Additionally, in the study of lifestyle and risk of skin aging in Japanese, Dr. Keiko Asakura, the lead scientists suggested, "Smoking status and topical sun protection were significantly associated with signs of visible skin aging in this study population" and " (There are) significant differences between sexes in the severity of hyperpigmentation, texture, and pores, but not wrinkling".
More precisely, skin aging can be caused by a number of factors, including
* The intrinsic aging of skin are factors that cannot be controlled, such as gene inherited from the parents, hormone change and cellular recession due to aging.
* The extrinsic aging of skin are factors that can or cannot be prevented, such as sun exposure, smoking, air pollution, bad eating habits, and physical inactivity.
Coffee, a popular and social beverage all over the world, particularly in the West, is a drink made from roasted bean from the Coffea plant, native to tropical Africa and Madagascar.
In the review of coffee caffeine effect in skin blood flow, researchers at the study lead by the Linköping University showed that intake of caffeinated coffee exhibits a stronger expression in increased skin microvascular response to transdermal iontophoresis of acetylcholine (ACh)( non‐invasively introduce vasoactive drugs in regulating the neurotransmitter at neuromuscular junctions), in compared to decaffeinated coffee intake group.
These result suggested that caffeine in coffee showed an enormous activity in increasing blood flow to the body's skin.
In a double-blind, placebo-controlled, crossover study performed in 27 healthy volunteers with oral intake of a cup either caffeinated or decaffeinated coffee and reactive hyperemia of finger blood flow assessed by laser Doppler flowmetry, within an interval of more than 2 days, the same experimental protocol was repeated with another coffee in a crossover manner, researchers showed that caffeinated coffee intake group demonstrated a slightly decreased finger blood flow in compared to decaffeinated coffee intake group.
According to the index of post-occlusive reactive hyperemia, microvascular endothelial function, in compared with decaffeinated coffee intake, caffeine contained showed an important effect in enhanced microvascular function in healthy individuals.
Taking together, the findings suggested that intake of coffee caffeine exerted a significant effect in promoted skin blood flow through a microvascular function which may have a strong impact in reducing the risk of skin aging.
