Acne
A common inflammation of the pores caused by buildup of sebum, keratinized cells, and the presence of the bacteria Propionibacterium acnes (P. acnes) deep in the follicle.

Active Ingredient
Components that impact cellular activity and structure, and stimulate or suppress function within the human body. Active ingredients work hard to bring about a change in the skin.

Alpha Hydroxy Acids (AHA's)
Exfoliants that remove the flaky, "dead" layer of skin from the epidermis (the skin's outermost layer) to improve the skin's texture and color, and speed up cell renewal. They 're also moisturizing and with continued use, may help smooth fine lines and wrinkles. AHA is the family name for a variety of acids: citric acid, glycolic acid, lactic acid, malic acid, and tartaric acid.

Amino Acid
A chemical compound containing nitrogen, carbon, hydrogen, and oxygen that is essential in protein structure. They are often used in cosmetic formulations to enhance water retention and skin moisturization.

Antioxidants
Ingredients such as vitamins A, C, and E that help the body to resist free radicals that prematurely age the skin. They interrupt oxidation, the spoilage process that makes iron rust, cut apples turn brown, and skin collagen break down. In cosmetics, antioxidants are often used to extend the shelf life of a product. Lecithin, tocopherol, and citric acid are some of the most common antioxidants
