Because salicylic acid dissolves in oil, it can work inside the pore, which makes it a common ingredient in acne face washes and serums.
Benefits
- Loosens dead skin and oil that clog pores
- Helps reduce blackheads and whiteheads
- Mildly calming, so it can reduce the redness of small pimples
How to use salicylic acid
- Start with a face wash or a leave-on product a few times a week
- Increase to daily use only if your skin is comfortable
- Always follow with moisturiser and use sunscreen in the morning
Precautions
- Can cause dryness or peeling, especially when combined with retinoids, benzoyl peroxide or other acids
- Avoid if you are allergic to aspirin (salicylates)
- Ask your doctor before using it during pregnancy or breastfeeding
- Higher-strength salicylic peels should be done only by a dermatologist
Who is it suitable for?
Best for oily, combination and acne-prone skin. Dry or sensitive skin may find it irritating; use it less often or only on oily areas.
Patch test first. Apply a small amount behind the ear or on the inner arm once a day for a few days. If you notice redness, burning, itching or swelling, do not use the product, and see a dermatologist if the reaction does not settle.
Common questions
How long before I see results?
Blackheads may start to improve in 4–6 weeks of regular use. If acne is not improving after 2–3 months, see a dermatologist.
