As one ages, this glue-like substance binds the skin cells tighter and denser. Dead skin layers build up and unlike young skin, natural exfoliation becomes difficult. This 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.

Both eyes may be treated by LASIK or PRK during the same procedure. The advantage of bilateral surgery is that it is more convenient to have both eyes done at once.
