“BIOSOURCE PURIFYING FOAMING CLEANSER”
This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (glycol stearate, lauric acid, myristic acid, palmitic acid, sodium 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.
ExfoliationSalicylic acid ~0.3–0.7%, below the ~0.5% it needsUnder-dosed
“Rids skin of impurities and dead skin cells, the skin is stimulated, smoothed, and looks more even.”
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.
