BHA
Scientific name: Salicylic Acid · Pore-clearing exfoliation, anti-acne

Frequently asked questions
› What does salicylic acid do?
Salicylic acid is oil-soluble, so it exfoliates inside the pore, dissolving the mix of sebum and dead skin that causes blackheads and congestion. Over time it helps keep pores clearer and skin smoother.
› Is salicylic acid or glycolic acid better for me?
Salicylic acid (BHA) works inside oily, congested pores, so it suits blackheads and blemish-prone skin. Glycolic acid (AHA) works on the surface for texture and brightness. Some routines use both, on different days.
› How often should I use a BHA?
Start two to three times a week and build up as your skin tolerates it. Some gentle low-percentage Korean formulas can be used daily, but let comfort be your guide.
› Can I use salicylic acid with retinol or niacinamide?
Niacinamide pairs well and can support the barrier. With retinol, many people alternate evenings rather than layering both at once, to avoid over-exfoliating. Introduce one active at a time.
