What the product description says
“PREP Facial 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 (cocamidopropyl hydroxysultaine, disodium lauryl sulfosuccinate, sodium grapeseedamidopropyl pg-dimonium chloride phosphate, sodium hydroxypropylphosphate laurylglucoside crosspolymer, sodium laurylglucosides hydroxypropylsulfonate) 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.

Cocamidopropyl hydroxysultaineEffect: HighUsed as a cleansing agent. Helps water and oil mix together~6–7.3%
Disodium lauryl sulfosuccinateEffect: HighUsed as a cleansing agent. Helps water and oil mix together~4.2–5.1%
Exfoliation

What the product description says
“Gently exfoliate and prime skin for optimal absorption of the OS-01 peptide with our daily cleanser.”
Source: ONe skin

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
