Kiehl's Over-Night Biological Peel
Kiehl's Over-Night Biological Peel helps to gently renew the skin with an overnight formula suitable for use on the most sensitive of skin types. Formulated with HEPES, this product keeps the skin's pH level balanced along with urea which works as a natural enzyme activator on the skin. With continual use this product will reduce pore size and help rid the skin of photo-damage and free-radicals. This face peel can be used up to three times a week to soften and smooth out the skin.
