Paula's Choice SKIN PERFECTING 2% BHA Liquid Exfoliant with Salicylic Acid, Facial Polish for Pores, Wrinkles * Fine Lines,….

Highlights:

  • Derived from willow bark, salicylic acid functions as a lipid-soluble compound capable of penetrating sebum-filled pores.
  • Beta hydroxy acid structure distinguishes this from water-soluble alpha hydroxy alternatives like glycolic or lactic acid.
  • pH range typically between 3.2 and 3.8 for optimal exfoliation without neutralization.
  • Developed originally in 1995 by Paula Begoun after formulation rejections from major cosmetic houses.
  • Butylene glycol serves as primary penetration enhancer, not alcohol as seen in comparable products.
  • Green tea extract inclusion provides polyphenol content, specifically epigallocatechin gallate, unrelated to core exfoliant function.
