Before you start

Lipophilic keratolytic active that can cause mild dryness, peeling, or tingling during initial use. Daily broad-spectrum sun protection is recommended.

Not recorded
Boundary
  • The 30% professional chemical peel outcomes cannot be expected from low-dose 0.5% daily consumer cleansers or leave-on toners.
  • The lipophilic, follicular-penetrating properties of free Salicylic Acid differ from hydrophilic AHAs like Glycolic Acid, making BHA superior for sebum-clogged pores but less hydrating on surface dry skin.
  • In-vitro antibacterial signals against Cutibacterium acnes do not replace systemic antibiotics in severe nodulocystic acne.
