“Exfoliates skin while cleansing.”
Source: Lookfantastic US

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~4–5.9%
Salicylic acidUnder-dosedUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~0.35–0.8%

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cetearyl alcohol, peg-7 glyceryl cocoate, polysorbate 20, triethanolamine) 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.

Peg-7 glyceryl cocoateEffect: HighHelps oils and water mix together and works as a cleansing agent~1.5–2.2%
Polysorbate 20Effect: HighHelps oil and water mix together~1.3–1.9%
Cetearyl alcoholEffect: HighA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.1–1.7%
TriethanolamineEffect: HighUsed to adjust pH of the product and can help improve the product's smell~0.85–1.25%
