You have probably heard a lot about AHAs, or alpha hydroxy acids, lately. AHAs often are found in creams and cleansers to help normalize cell renewal by loosening the dead cells of the skin.

As skin gets older or becomes damage by the sun. Most of the benefit is in exfoliation, or the removal of dead skin cells, which exposes newer skin cells and gives skin a younger healthier looking appearance. On average, the skin takes 28 days to 40 days to renew itself.

In mature skin, the cell renewal and exfoliation processes diminish and dead skin cells tend to accumulate, making skin appear and feel rough, dry and damaged. AHAs also help increase the skin's moisture retention, keeping the skin feeling soft and smooth.

Studies have shown the benefits of AHAs in treating sun damaged skin by helping to reverse some of the negative effects caused by the sun on skin collagen and elastin fibers.

Discuss the benefits of alpha hydroxy acids in your homecare with your dermatologist or skincare specialist.
