 Alpha
hydroxy acids is one of the most commonly used treatment agent for the skin
infections and skin diseases. Its uses ranges from a cleaning agent to a
intoxicating agent. They work by rejuvinating the skin and making it afresh.
Alpha Hydroxy Acids
Alpha hydroxy acids are derived from fruit and milk sugars. The most
commonly used alpha hydroxy acids are glycolic acid and lactic acid because
they have a special ability to penetrate the skin.They also have the most
scientific data on their effectiveness |
and side effects.
Natural fruit acids (alpha hydroxy acids or AHAs) rejuvenate the skin by
encouraging the shedding of old, sun-damaged surface skin cells. Glycolic
acid is the alpha hydroxy acid most frequently used for facial treatments
but lactic and citric acid are also useful. Of course, lactic acid doesn't
come from fruit - it comes from milk.
Uses of Alpha Hydroxy Acid in Peels
Alpha hydroxy acids in various concentrations are used in chemical peels.
The concentration determines who can use it. Alpha hydroxy acid products
sold to consumers must have a concentration of less than 10%. Trained
cosmetologists can use alpha hydroxy acid products that have a concentration
of 20% to 30%.
Alpha hydroxy acids are found in a variety of skin care products including
moisturizers, cleansers, eye cream, sunscreen, and foundations.

Alpha Hydroxy Acid products
There are many products with varying concentrations of various fruit acids
in differing bases. For the best results, leave-on fruit acid preparations
should be applied at night, if necessary twice daily. They can be alternated
with other anti-aging preparations including retinoid creams and vitamin C.
Word of caution about Alpha Hydroxy Acid
Cosmetics that contain alpha hydroxy acids (AHAs) have become widely used in
recent years despite many unanswered questions about their safety. Recently,
a study sponsored by the cosmetics industry indicates that these products
may make users more sensitive to sunlight and especially to the ultraviolet
(UV) radiation component of sunlight. UV exposure can damage the skin and at
high doses, especially over a long period, can cause skin cancer. FDA is
currently evaluating this study and is pursuing additional studies that will
make sure these products are safe for consumers to use. |
