Common questions
Is COSRX Master Patch Intensive 36s fragrance-free?
No added fragrance (parfum) is listed, but it contains essential oils (melaleuca alternifolia (tea tree) leaf oil), which give it a scent and are a common cause of irritation.
Does COSRX Master Patch Intensive 36s contain alcohol?
No drying alcohol (alcohol denat. or ethanol) is listed.
Is COSRX Master Patch Intensive 36s 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. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
Is COSRX Master Patch Intensive 36s suitable for sensitive skin?
It contains essential oils and salicylic acid, an exfoliating acid, which can bother sensitive skin. Patch-test it before using it all over.
