What the product description says
“L-Lactic Cleanser”
From product name

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (ammonium lauryl sulfate, decyl glucoside, 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: ammonium lauryl sulfate, decyl glucoside

Ammonium lauryl sulfateEffect: High~5.1–7.7%
Decyl glucosideEffect: HighHelps oil and water mix together. Can be irritating~2.3–3.5%
Xanthan gumEffect: HighUsed to create a thicker product consistency~1.4–2.1%

Lactic acid

What the product description says
“Cleansing aside, it also encourages the skin’s own natural exfoliation process, known as desquamation.”
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: lactic acid.

Lactic acidKey activeEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~2.7–4%
