Kiehl's Clearly Corrective™ Daily Triple Acid Peel:
Kiehl's Clearly Corrective Daily Triple Acid Peel is a lightweight, leave-on peel serum formulated with a triple acid blend that works on 3 levels of skin to smooth, brighten and visibly minimize the appearance of pores while being gentle enough for daily use. The product features an 8.6% blend of PHA (Polyhydroxy Acid), BHA (Beta-hydroxy Acid) and AHAs (Alpha-Hydroxy Acid, with Glycolic and Lactic acids).

Skincare acids are known to be effective for smoothing and brightening, but many solutions can be too harsh, resulting in potential harm to the skin barrier. The product is balanced with Copper Gluconate to help reduce potential discomfort, and also gives the formula its unique blue color.

Ingredient Technology: 

• Triple Acid Blend (PHA + BHA + AHAs)
  • Gluconolactone (PHA) helps target top surface level skin to smooth texture, hydrate, and boost radiance.
  • Salicylic Acid (BHA) helps target mid-surface level skin to break down oil, clarify pores, and reduce the appearance of pore size.
  • Glycolic Acid (AHA) is a naturally occurring fruit acid derived from sugar cane, known to help smooth skin, targeting deeper surface layers. Lactic Acid (AHA) helps gently exfoliate while diminishing the look of fine lines and uneven texture.
• Copper Gluconate - Reduces potential skin discomfort.

Following a consumer perception study after 4 weeks of use:

• 91% saw smoother skin¹
• 88% saw more radiant skin¹
• 88% saw minimized pores¹

Our leave-on peel serum may be layered with or used in rotation with our Micro-Dose Retinol serum for superior skin renewal, with 91% of consumers agreeing that their skin's complexion was transformed¹.
