Common questions

Is COSRX All About Snail Kit 4-step fragrance-free?

No. Fragrance (listed as "Fragrance") is the 14th of 78 ingredients.

Does COSRX All About Snail Kit 4-step 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 All About Snail Kit 4-step safe for fungal acne?

It contains 9 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty acids (palmitic acid, stearic acid); fatty-acid esters & glycerides (cetearyl olivate, sorbitan olivate); plant oils & butters (helianthus annuus (sunflower) seed oil); and 4 more. 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.
