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 Reduces fine lines Minimizes signs of discomfort like visible redness and dryness Gentle enough for daily use (twice a day) For all skin types Before and After: At the Kiehl's labs, they 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. Kiehl's formula is demonstrated to visibly smooth skin texture: 88% Saw Minimized Pores 91% Agreed Skin Appears Smoother 88% Saw More Radiant Skin Based on a consumer perception study after 4 weeks of use Key Ingredients: Salicylic Acid is a beta-hydroxy acid that helps to clarify pores and refine skin texture. Glycolic Acid is a naturally occurring fruit acid derived from sugar cane known to help smooth skin. Lactic Acid is an alpha hydroxy acid known for its exfoliation properties that helps gently exfoliate skin and diminish the look of fine lines and uneven skin texture.
