Common questions
Is Dr.Jart+ K-Mask Hydration Week fragrance-free?
No added fragrance (parfum) is listed, but it contains essential oils (pelargonium graveolens (geranium) flower oil, citrus aurantium bergamia (bergamot) fruit oil and salvia officinalis (sage) oil), which give it a scent and are a common cause of irritation.
Does Dr.Jart+ K-Mask Hydration Week contain alcohol?
No drying alcohol (alcohol denat. or ethanol) is listed. It does contain cetearyl alcohol and behenyl alcohol: fatty alcohols that soften and thicken the formula and aren't drying.
Is Dr.Jart+ K-Mask Hydration Week safe for fungal acne?
It contains 7 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (polyglyceryl-10 laurate, glyceryl stearate, polyglyceryl-10 stearate, glyceryl stearate se); plant oils & butters (olea europaea (olive) fruit oil); and 2 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.
Is Dr.Jart+ K-Mask Hydration Week suitable for sensitive skin?
It contains essential oils, which can bother sensitive skin. Patch-test it before using it all over.
