The short answer: Salicylic acid is a beta hydroxy acid (BHA) that is oil-soluble, so it can work inside the pore, loosening the oil and dead skin that form blackheads and whiteheads. Start with a 2% leave-on toner or pad a few times a week, build up as your skin tolerates it, keep moisturizing, and wear broad-spectrum SPF 30+ every morning.
Every fall, routines get richer. Heavier creams come out, heat dries the air, and somewhere around the nose and chin, pores start to look a little more crowded. If that sounds familiar, salicylic acid deserves a spot on your shelf. It is a practical, generally well-tolerated exfoliant, and it is especially good at the job most of us actually want done: clearing out pores.
The problem is that it is easy to overdo. Too much, too often, and you trade blackheads for flakes. We looked at the BHA lineup at DermStreet and pulled together exactly how to use it, who it suits, and which formula to choose for your skin.
What is salicylic acid?
Salicylic acid is a beta hydroxy acid, or BHA. You will find it in acne-focused cleansers, toners, pads, serums and spot treatments. Unlike the alpha hydroxy acids (AHAs), it is oil-soluble, which is what makes it a go-to ingredient for blackheads, whiteheads and congested, oily skin.
How does salicylic acid unclog pores?
Clogged pores form when dead skin cells, oil or dirt get trapped in the pore. Because salicylic acid dissolves in oil, the Cleveland Clinic explains, BHAs penetrate deeper into pores than water-soluble AHAs. That lets them help loosen the plug from within rather than only polishing the surface.
It also helps with the look of large pores. The American Academy of Dermatology (AAD) notes that when pores clog, they expand, which makes them more noticeable. Keeping them clear helps them look smaller.
What salicylic acid helps with:
✔ Blackheads and whiteheads
✔ Congestion on the nose, chin and forehead
✔ The look of enlarged pores
✔ Excess shine and rough texture
✔ Mild breakouts, as part of a consistent routine
Salicylic acid (BHA) vs. glycolic and lactic acid (AHA)
| Salicylic acid (BHA) | Glycolic acid (AHA) | Lactic acid (AHA) | |
|---|---|---|---|
| Dissolves in | Oil | Water | Water |
| Works best on | Inside pores: blackheads, whiteheads | Surface texture, dullness, the look of fine lines | Gentle surface smoothing |
| Ideal skin type | Oily, combination, breakout-prone | Normal, sun-damaged, aging | Dry and sensitive |
| Irritation potential | Generally well tolerated | Can be strong; start slowly | One of the gentler AHAs |
Many formulas combine both families. The Cleveland Clinic notes that salicylic acid is not overly irritating for most people and that most can use it up to twice a day, while glycolic acid can be strong and is best introduced one or two nights a week. For a wider primer, see our Exfoliation 101 guide.
Who should use salicylic acid, and who should skip it?
Great for: oily and combination skin, blackhead-prone noses, and anyone whose pores look more visible as the weather changes.
Go slowly or check first if:
✔ Your skin is very dry, sensitive or rosacea-prone; a gentler, lower-frequency option may suit you better
✔ You already use a retinoid or other exfoliant; alternate nights rather than stacking
✔ You are pregnant or breastfeeding, or allergic to aspirin; ask your doctor before using salicylic acid products
✔ Your acne is painful, inflamed or deep; see a dermatologist
Acids can leave skin more prone to sun damage, so daily SPF 30+ is non-negotiable. If redness and post-breakout marks are your bigger concern, our azelaic acid guide is a good next read.

How to add salicylic acid to your routine
Morning: Gentle, non-comedogenic cleanser with lukewarm water → oil-free moisturizer → broad-spectrum SPF 30+, even on cloudy or cold days.
Evening: Gentle cleanser → BHA toner or pad on congested areas (start two or three nights a week) → moisturizer.
Rules that keep BHA comfortable:
✔ Apply to clean, dry skin and avoid the eye area
✔ Increase frequency only if your skin stays calm
✔ If it stings or flakes, the AAD suggests using a mild cleanser in the morning and saving salicylic acid for night
✔ Skip hot water, harsh scrubs and picking, which inflame skin and make pores more noticeable
✔ Look for "non-comedogenic" or "oil-free" on moisturizers and sunscreens, and avoid heavy facial oils like coconut or olive oil on congested areas

Frequently Asked Questions
Does salicylic acid really unclog pores?
Yes. Because it is oil-soluble, salicylic acid can get into pores and help loosen the mix of oil and dead skin that causes blackheads and whiteheads.
How often should I use salicylic acid?
Start two or three times a week. Many people can work up to daily or even twice-daily use, but cut back if you notice dryness, stinging or flaking.
Can I use salicylic acid with retinol?
Yes, but not usually in the same step. Alternate nights to lower the risk of irritation, and moisturize well.
Is salicylic acid better than glycolic acid for blackheads?
For blackheads, usually yes. Salicylic acid is oil-soluble and works inside pores, while glycolic acid works mostly on the surface for texture and dullness.
Does salicylic acid make you sensitive to the sun?
Exfoliating acids can leave skin more prone to sun damage, so wear broad-spectrum SPF 30 or higher every day.
