Yes. Salicylic acid is oil-friendly, which is why it suits oily and combination skin, blackheads and congested-looking areas. Start with a 2% leave-on product two or three times a week, on the areas that need it rather than the whole face, and build up only if your skin stays comfortable. Follow it with moisturiser so it does not leave you tight.

Salicylic acid, or BHA, is oil-friendly, which makes it a favourite for oily and combination skin, blackheads and congestion. In cosmetic terms it clarifies and refines. It's especially suited to non-inflamed bumps, where benzoyl peroxide tends to suit angrier breakouts.

What Salicylic Acid is

BHA is a beta hydroxy acid that works on the surface and around pores, which is why oily and congestion-prone skin reaches for it. Modern 2% formulas are gentle enough for regular use. It can get drying if you overdo it, so a little and often beats piling it on.

What is Salicylic Acid good for?

oily and combination skin
blackheads and a congested-looking surface
non-inflamed bumps and rough texture
an overall clearer, refined-looking finish

How do you use Salicylic Acid?

Usually a night active; start a few times a week.
Don't overdo it, since too much can leave skin feeling dry.
A 2% leave-on formula is the well-studied everyday strength.
Keep up morning SPF while you use it.

Baselit places BHA in the evening and keeps it off the same night as a retinoid.

What does it pair with?

Keep BHA away from other strong actives (retinoids, benzoyl peroxide, other acids and pure vitamin C) in the same routine so you don't over-do it. Baselit spaces actives out for you.

Frequently asked questions

What does salicylic acid (BHA) do for skin?

In cosmetic terms, salicylic acid clarifies and refines. Because it's oil-friendly, it suits oily and combination skin, blackheads and a congested-looking surface, and helps skin look clearer and more refined.

Is BHA or benzoyl peroxide better for breakouts?

They suit different looks. BHA is especially suited to non-inflamed bumps and congestion, while benzoyl peroxide tends to suit angrier, inflamed breakouts better. Some routines use them on different days.

How often should I use salicylic acid?

Start a few times a week rather than daily. BHA can get drying if you overdo it, so a little and often is kinder to your skin than piling it on.

Can I use BHA with retinol?

Keep them apart in the same routine, since stacking strong actives can over-do it. Baselit's routine builder spaces actives out so nothing clashes and your skin stays comfortable.

What strength of salicylic acid should I use?

A 2% leave-on formula is the well-studied everyday strength and is gentle enough for regular use. There's no need to chase higher numbers for daily care.
