What the product description says
“Botanical foam face wash with a focus on natural and plant-derived ingredients.”
Source: Yesstyle

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamidopropyl betaine, lauric acid, lauryl betaine, potassium cocoate, potassium cocoyl glycinate) 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

Potassium cocoyl glycinateEffect: High~3.9–5.9%
Cocamidopropyl betaineEffect: HighHelps water and oil mix together. Used as a cleansing ingredient. Could be an allergen~2.2–3.3%

Lauric acidEffect: HighHelps water and oil mix together. Has anti-bacterial properties that might be helpful in preventing blemishes~0.35–0.85%
