What the product description says
“This wash also helps soothe and condition the look of skin, leaving it thoroughly clean and residue-free.”
Source: Sephora

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (cocamidopropyl betaine, lauryl glucoside, peg-120 methyl glucose dioleate, peg-150 pentaerythrityl tetrastearate, peg-40 hydrogenated castor oil, peg-6 caprylic/capric glycerides, sodium laureth sulfate) 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 laureth sulfate
