Common questions

Is COSRX Oil Free Ultra Moisturizing Lotion fragrance-free?

No added fragrance (parfum) is listed, but it contains essential oils (citrus medica limonum (lemon) peel oil), which give it a scent and are a common cause of irritation.

Does COSRX Oil Free Ultra Moisturizing Lotion contain alcohol?

No drying alcohol (alcohol denat. or ethanol) is listed. It does contain cetearyl alcohol: a fatty alcohol that softens and thickens the formula and isn't drying.

Is COSRX Oil Free Ultra Moisturizing Lotion safe for fungal acne?

It contains 2 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (cetearyl olivate, sorbitan olivate). How much they matter depends on the amount and the rest of the formula. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
