Gentle cleansing and resurfacing for a healthy, youthful glow. This exfoliating cleanser is tailored to collaborate with the retinoids in this Enzyme-Active Retinol™ Night Serum. Unlike physical scrubs that essentially scratch your face in irregular patterns, the two Alpha Hydroxy Acids (AHAs) used in this cleanser (glycolic acid and lactic acid) are proven by dermatologists to. For clients who use a salicylic acid or other acne cleanser for controlling breakouts recommend "double" cleansing and applying those products afterwards. For clients who do not use a dedicated breakout-controlling cleanser, this functions perfectly as a daily cleanser. Use as leave-on mask for extraordinary chemical purification.
