Exfoliant

Salicylic Acid

Also known as BHA, beta hydroxy acid

An oil-soluble exfoliant that works inside the pore to clear out oil and dead skin, so breakouts and blackheads are less likely to form.

What is salicylic acid?

Salicylic acid is a beta hydroxy acid (BHA), originally sourced from willow bark. Unlike water-soluble acids such as glycolic acid, it dissolves in oil. That lets it move into the pore lining, where it loosens the mix of oil and dead skin cells that turns into blackheads and breakouts.

What it does for your skin

  • Clears out clogged pores and helps prevent new blemishes
  • Softens rough texture by loosening dead surface cells
  • Helps oily skin look less shiny through the day
  • Calms the look of redness around active spots

How to use it

A 2% salicylic acid cleanser is an easy way to start because it rinses off. Massage it over damp skin for 30 to 60 seconds so it has time to work, then rinse. A leave-on toner gives a stronger effect. If your skin gets dry or tight, use it once a day instead of twice and follow with a light, oil-free moisturizer.

Who it's for

Salicylic acid suits oily, combination and breakout-prone skin best. Dry or very sensitive skin can still use it, but a rinse-off cleanser a few times a week is a gentler starting point.

Common questions

Can I use salicylic acid every day?
Yes, most people can use a 2% salicylic acid cleanser once or twice a day. Start once a day and build up if your skin feels comfortable.
Can I use salicylic acid with benzoyl peroxide?
Yes. A common routine is a salicylic acid cleanser daily and benzoyl peroxide as a spot treatment. Go slowly to avoid dryness.
Is salicylic acid safe during pregnancy?
Check with your doctor or pharmacist first. Guidance differs for wash-off and leave-on products.
How long does salicylic acid take to work?
Skin often feels clearer within a couple of weeks, but give it 6 to 8 weeks of steady use to see the full change in breakouts.
