Lactic Acid Peels
Lactic acid is derived from yogurt, buttermilk,
or sour cream and is much milder than other alpha hydroxy acids such
as glycolic acid. Lactic Acid is already in humans cells which makes
it a safer hydroxy acid to use than alpha hydroxy’s such glycolic
acid.
This is an advantage for first timer
users or those with sensitive skin. Lactic Acid has one of the largest
molecules, so penetration is much slower which results in less irritation
to the skin.
As with Glycolic Acid, it works by loosening the glue like substance
that bind skin cells together. It works on the epidermis
layer of the skin only, so it is not a deep peel. However it does
stimulate elastic fibers and promotes growth new collagen in the dermis
layer of the skin.
