What is Lactic Acid?
Lactic Acid belongs to a group of chemical compounds known as AHA's (Alpha Hydroxy Acid). AHA are very well known in skin care and beauty products as exfoliants and skin lightening agents. Other members of the group include Glycolic acid (used in chemical peels) and Citric acid (used mostly as a pH balancing agent in cosmetics). Lactic acid can be derived from sour milk.

AHA and BHA
If you have heard of BHA's (Beta hydroxy acids) then it's important to know the difference between the two. The most common examples of BHA is Salicylic acid. AHA's and BHA's work on the same principle of causing the skin to shed its dead skin cells. It dissolves key elements that bind the cells together. However, AHA's can dissolve in water while BHA's only dissolve in fats and oils. This means that AHA's are better for normal to dry skin.
Benefits Of AHA
- Like all AHA's lactic acid is an exfoliating agent which means that it helps the skin to shed its top layer skin cells thereby exposing healthier and brighter skin cells below
- This exfoliation process helps the skin to look more robust, brighter and lighter in complexion.
- Lactic acid help diminish the wrinkles and fine lines associated with aging skin
- Lactic acids are able to lighten the skin and diminish the visible effects of spots and acne scars
- Lactic acid helps to encourage the skin to generate collagen which is important for skin health
Side Effects of AHA and BHA
Using both AHA like Lactic acid can be followed by side effects like dryness and flaking of the skin but this lasts only a few weeks. This happens while the skin is still adjusting and clears with time. Many products are based on Salicylic acid or combine it with some other ingredients.
