Here’s a link to the lactic acid peel I use on my facial skin: http://www.amazon.com/gp/product/B006ZBP8NM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 It also has kojic acid.
Kojic acid, often used as an ingredient in Asian diets, is a more recent discovery for the treatment of pigmentation problems and age spots. Discovered in 1989, kojic acid is now used extensively as a natural alternative to hydroquinone. Kojic acid is derived from a fungus, and studies have shown that it is effective as a lightening agent, inhibiting production of melanin (brown pigment). Kojic acid is a by-product in the fermentation process of malting rice for use in the manufacturing of sake, the Japanese rice wine. There is convincing research, both in vitro (in a test tube) and in vivo (on a live subject), showing kojic acid to be effective for inhibiting melanin production.
Also an AHA (alpha hydroxy acid), Lactic acid mimics the properties of Glycolic acid but is typically better suited for individuals with sensitive skin. AHA’s such as Lactic Acid can assist other ingredients in skin lighteners by allowing them to penetrate farther into the skin.
