Salicylic Acid (BHA)
The oil-soluble BHA — helps unclog pores and smooth oily, congested skin.
What it is
Salicylic acid is a beta hydroxy acid (BHA). Unlike water-loving AHAs, it is oil-soluble, so it can get into oily pores and loosen the buildup behind blackheads and congestion. It is a staple for oily and blemish-prone skin.

Start 2–3 times a week — daily use can over-dry and irritate. It can make skin more sun-sensitive, so daily SPF matters. During pregnancy, ask your doctor before using leave-on BHA. Not an acne treatment for persistent or cystic breakouts.
AHA vs BHA — what is the difference?
AHAs (glycolic, lactic) are water-soluble and work on the surface for tone and texture. BHA (salicylic acid) is oil-soluble and gets into pores, so it is the usual pick for oily, congested skin.
What percentage of salicylic acid should I use?
Leave-on products are commonly 0.5–2%. Higher is not better for daily use — 2% is the classic effective strength, and 0.5–1% is gentler if you are starting out.
Can I use salicylic acid with retinol?
You can, but using both at full strength every night is a common cause of irritation. Alternate nights or buffer with moisturizer — and for persistent breakouts, see a board-certified dermatologist.
Ingredients help the look and feel of skin; they do not treat medical conditions. No brand paid to be here. Skincare information, not medical advice — for a persistent concern, see a board-certified dermatologist.
