What the product description says
“This foaming cleanser, with gentle exfoliating acids, effectively lifts impurities, oil and makeup from the skin's surface to reveal a fresh and bright complexion.”
Source: Skinstore

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: salicylic acid.

Salicylic acidKey activeEffect: HighUsed 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)~0.25–0.5%

What the product description says
“Foaming Gel Cleanser”
Source: Skinstore

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (carbomer, cocamidopropyl betaine, peg-60 almond glycerides, polysorbate 20, sodium c12-18 alkyl sulfate, sodium c14-16 olefin sulfonate) 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, sodium c14-16 olefin sulfonate

Polysorbate 20Effect: HighHelps oil and water mix together~4–4.8%
Sodium c12-18 alkyl sulfateEffect: High~3.4–4.1%
Cocamidopropyl betaineEffect: HighHelps water and oil mix together. Used as a cleansing ingredient. Could be an allergen~3–3.7%
Sodium c14-16 olefin sulfonateEffect: HighHelps oil and water mix together and used as a cleansing agent. Can be irritating and is better avoided for sensitive skin~1.8–2.2%
Peg-60 almond glyceridesEffect: High~0.3–0.5%
CarbomerEffect: HighHelps create a thicker or gel-like product texture. It is not a surfactant but can be used in gentle cleansing formulations~0.25–0.5%
