FAQs

WHEN DO I USE BHA SERUM? Use after cleansing and hydrating, as your 'Treat' step. AM or PM - but always wear SPF if used in the morning.

HOW OFTEN SHOULD I USE IT? Daily in the PM is fine for most. If your skin is dry or sensitive, start with 1–3 times a week.

CAN I LAYER IT WITH OTHER INGREDIENTS? Avoid using with other exfoliating acids (AHAs, BHAs, PHA), Vitamin C or Retinol in the same routine. Alternate evenings instead to avoid irritation.

IS IT SUITABLE FOR SENSITIVE SKIN? Yes - just patch test first and build up slowly.

CAN I USE IT ON DRY, BLEMISH-PRONE SKIN? Yes. It’s formulated with 1% Hyaluronic Acid so it won’t dry you out. Use 2–3 times a week if needed.

WILL IT HELP WITH BLACKHEADS? Yes. 2% Salicylic Acid helps unclog pores and reduce blackheads, breakouts + pore size.

IS IT COMEDOGENIC? No - it contains no pore-clogging ingredients.

WHAT'S THE PH? 4.5–5.3 AHAS VS BHAS - WHAT’S THE DIFFERENCE? Alpha Hydroxy Acidsd (AHAs) = surface exfoliation (e.g. Glycolic Acid). Beta Hydroxy Acids (BHAs) = deeper exfoliation inside pores (e.g. Salicylic Acid). Use AHAs in PM, BHAs can be AM or PM - always follow with SPF.

HOW LONG UNTIL I SEE RESULTS? Up to 6 weeks. Be consistent. Don’t overdo it - more isn’t better.

IS IT VEGAN? Yes! Certified by The Vegan Society.

IS IT SAFE DURING PREGNANCY? Yes

CAN I USE IT WITH PRESCRIPTION MEDS? Check with your doctor first.
