What is Salicylic Acid?

The Science

Salicylic acid is a beta hydroxy acid (BHA) derived from willow bark. Its unique molecular structure allows it to penetrate oil and exfoliate inside pores, making it highly effective for acne-prone skin.

  • Lipophilic (oil-loving) molecule
  • Keratolytic agent (breaks down dead skin)
  • Anti-inflammatory properties
  • Antimicrobial effects

How It Works

Unlike alpha hydroxy acids (AHAs), salicylic acid's oil-soluble nature allows it to:

  1. Penetrate through sebum into pores
  2. Break down keratin plugs and dead cells
  3. Reduce oil production
  4. Calm inflammation
Key Difference: BHAs work inside pores, while AHAs work on the surface.
