One promising treatment in the growing collection of anti-aging treatments is alpha hydroxy. Alpha hydroxy acids (AHA) are synthetic versions of acids derived from sugar-containing fruits, such as glycolic acid and malic acid. Acid concentrations in over-the-counter AHA creams generally range from two to 10 percent, while prescription products contain a minimum of 12 percent glycolic acid. Many skin improvements are possible with the regular use of alpha hydroxy.
Exfoliates
Alpha hydroxy acids are perhaps best known for their exfoliating (resurfacing) properties. They effectively slough off the outer layer of old, dead skin and encourage the growth of new skin that is evenly pigmented and smoother. Exfoliating the skin may help eliminate small wrinkles. Always apply sunscreen to your face when using these products and for several days afterward because they can make your skin more sensitive to the damaging effects of the sun. The American Academy of Dermatology says side effects from AHA peels and products may include burns, itching, pain and possibly scarring.
Stimulates Collagen
Alpha hydroxy acids may simultaneously shed dead skin cells while encouraging collagen and elastin production, according to the University of Maryland Medical Center. Collagen is the primary protein found in connective tissue and gives skin its strength and fullness. Elastin is a protein that gives skin tissue its elasticity. These proteins wear down as your skin ages, leading to fine lines and wrinkles. Consistent use of alpha hydroxy products may minimize wrinkles and give your skin a healthy glow.
Reverses Sun Damage
Alpha hydroxy acids may help reverse some of the damaging effects of the sun. Ultraviolet A (UVA) is primarily responsible for premature aging and wrinkles. The classic sign of overexposure to the sun is premature wrinkling of the skin. Other signs include skin that is dry, thin and rough. Some people develop tiny red veins on the nose, cheeks and ears, and/or age spots that are commonly brownish in color.
