Kiehl's targeted gentle facial peel is specifically formulated with 5.5% AHAs (Glycolic Acid and Lactic Acid), 0.18% BHA (Salicylic Acid), and 3.0% PHA (Gluconolactone) to help reduce the appearance of pores, boost skin's radiance, and create visibly softer and smoother skin texture. Balanced with soothing Copper Gluconate to help reduce discomfort, this formula provides a gentle exfoliating peel that can be used daily. What It's Good For: Helps to visibly reduce the appearance of pores and excess surface oil Visibly smooths skin texture and creates a more even skin tone Boosts skin's radiance Gentle enough for daily use (twice a day) For all skin types Sized to meet TSA guidelines Before and After: At the Kiehl's labs, we tested the skin to see how deeply within its outer surface layer this targeted facial pre-serum penetrated to improve texture. More blue lines indicate a rougher skin texture that's less radiant and more uneven. After using Clearly Corrective™ Daily Re-Texturizing Triple Acid Peel, less blue lines show diminished rough texture for smoother, more radiant skin.
