Common questions

Is COSRX AHA/BHA Clarifying Treatment Toner fragrance-free?

Yes. No fragrance, essential oils or fragrance allergens are listed in its ingredients.

Does COSRX AHA/BHA Clarifying Treatment Toner contain alcohol?

No drying alcohol (alcohol denat. or ethanol) is listed.

Is COSRX AHA/BHA Clarifying Treatment Toner safe for fungal acne?

None of the ingredients usually flagged for fungal acne are listed: fatty acids with 11–24 carbons and their esters, polysorbates, plant oils and butters, or ferments. 3 of its ingredients aren't in our glossary yet, so check those yourself. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
