Alpha Hydroxy Acids (AHAs)
A group of non-toxic, organic substances naturally occurring in many common fruits and foods (such as malic acid from apples, tartaric acid from grapes, citric acid from citrus fruits, and lactic acid from sour milk), widely referred to as "fruit acids."
Dehydration
Loss of water or moisture.
Emollient
Softening and smoothing.
Exfoliation
The "sloughing away" of dead skin cells — part of the skin's natural rejuvenation process
Glycolic Acid
The simplest of all the Alpha Hydroxy Acids. Glycolic Acid is believed to have the greatest penetration potential due to its small molecular size. As a result, Glycolic Acid is believed to provide the greatest benefits for skin care in comparison to other cosmetically used AHAs (lactic, malic, citric, tartaric, etc.).
Humectant
An ingredient or combination of ingredients that has the ability to "bind and hold" water molecules to help prevent the loss or evaporation of water.
Hyperpigmentation
Excessive discolorations resulting in darker areas on the skin — such as brown spots and other skin discolorations.
Moisturizer
An ingredient or combination of ingredients which adds water to the skin's surface.
Non-comedogenic
Will not clog pores.
Photosensitivity
Skin sensitivity caused by exposure to the sun's harmful rays.
Photodamage
Damage to the skin caused by overexposure to the sun, for example: fine lines, hyperpigmentation and thickened, dry skin.
