Is BHA better than AHA for acne?

Yes. BHA (salicylic acid) is the first choice for active acne because the fat-soluble molecule penetrates pores where acne bacteria sit. AHA (glycolic acid) works on the skin surface and is better for pigment and tone.

Can I use salicylic acid daily?

Low-concentration home products (1-2%) can be used 2-5 times per week. Clinical peels at 20-30% are run as a course of 4-6 sessions spaced 2-3 weeks apart, then maintenance every 6 months.

Can I get salicylic acid during pregnancy?

Topical salicylic acid in low concentration (under 2%) is considered safe. Clinical peels at 20-30% are avoided — the substance is absorbed systemically and is FDA category C at higher doses.

Is salicylic acid known by another name?

Yes — salicylic acid is related to aspirin (acetylsalicylic acid). They share anti-inflammatory properties but aspirin is acetylated for better oral absorption. People with aspirin allergy should inform their injector.

Also known as: BHA, beta hydroxy acid, salicylic acid

What is salicylic acid?

Salicylic acid is a beta hydroxy acid (BHA) originally derived from willow bark and other plants. It is related to aspirin (acetylsalicylic acid) and shares its anti-inflammatory properties. The key difference from glycolic acid: salicylic acid is fat-soluble and can reach into oil-filled pores where water-soluble AHAs cannot.

How it works in treatment

Salicylic acid has three actions. Comedolytic: dissolves oil plugs in pores. Keratolytic: loosens bonds between dead skin cells. Anti-inflammatory: reduces redness and swelling in acne. It works in a pH-dependent way — lower pH gives a stronger effect. Clinical peels run at 20-30 percent.

Where it is used

Salicylic acid is the first choice for active acne, blackheads, whiteheads, and oily skin. Also effective for post-acne pigmentation and enlarged pores. At Dibélle it features in specialised acne peels and combination peels alongside glycolic acid or TCA.

Results and safety

Results on acne often show within the first course of 4-6 sessions. Acne can flare temporarily during the first week as deeper comedones surface. Salicylic acid is absorbed systemically — high doses are avoided in pregnancy, breastfeeding, and in patients with salicylate sensitivity.
