How AHA works?
To find out how AHA works for skin care, lets see how the skin grows old and how to keep it younger.
Cells in the outer layers of skin are bound together by inter-cellular fluid. As one ages, this 'glue-like' substance binds the skin cells tighter and denser. Dead skin layers build up and unlike younger skin, natural exfoliation becomes difficult. The AHA group of natural acids has the ability to loosen this inter-cellular fluid and allows the top layer of dead skin to slough off easily. Thus AHA products cause exfoliation, or shedding of the surface skin. The extent of exfoliation depends on the type and concentration of the AHA, its pH (acidity), and other ingredients in the product. Most skin care cosmetics sold to consumers contain AHA at levels up to 10 percent.
