“A non-stripping face and body cleanser formulated with 50% glycerin and 5% glycolic acid that resurfaces for brighter, firmer looking skin.”
Source: Prequel

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: glycolic acid.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~3.6–5.4%

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamidopropyl betaine, coco-glucoside, glycol distearate, sodium cocoyl isethionate, xanthan gum) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

Even though this formulation is mild, the following cleansing agents could trigger an irritation or allergy for some people: cocamidopropyl betaine, coco-glucoside

Sodium cocoyl isethionateEffect: HighHelps water and oil mix together. Can be used as a cleansing agent~5–7.5%
Cocamidopropyl betaineEffect: HighHelps water and oil mix together. Used as a cleansing ingredient. Could be an allergen~3.3–4.9%
Coco-glucosideEffect: HighUsed as a cleansing agent (surfactant) in cleansers. Helps water and oil mix together in lotions. Can be irritating~1.1–1.7%
Glycol distearateEffect: HighHelps water and oil mix together~0.95–1.45%
Xanthan gumEffect: HighUsed to create a thicker product consistency~0.05–0.2%
LecithinEffect: High, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.1–0.5%
