“DER. THERAPY Refreshing Scrub To Body Wash THERAPY Refreshing Scrub To Body Wash”
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, hydrogenated lecithin) 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

Ammonium lauryl sulfateEffect: High~9.1–11.1%
Hydrogenated lecithinEffect: HighHelps to retain moisture by creating a protective barrier on the skin. Rich in fatty acids. Improves product texture and helps with the penetration of other ingredients.~0.2–0.35%

What the product description says
“DER. THERAPY Refreshing Scrub To Body Wash THERAPY Refreshing Scrub To Body Wash”
From product name

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.

Microcrystalline celluloseEffect: Low~2.2–2.7%
