Salicylic Acid (BHA)

What it actually does

An oil-loving exfoliant that gets inside pores to clear out gunk that leads to blackheads and breakouts.

How to use it

Use PM only, 2–3 nights a week to start. Apply after cleansing, before hydrating layers. Sunscreen the next morning is non-negotiable.

The science, in plain English

An oil-soluble beta-hydroxy acid that dissolves the sebum-plus-dead-skin mix inside pores.

Myth vs reality

It is not just for teens — adult hormonal breakouts and clogged pores respond just as well.

  • Niacinamide
  • Ceramides
  • Hyaluronic Acid

Don't layer with

  • Retinol on the same night
