Common questions

Is No7 Prime Forever Serum fragrance-free?

No. Fragrance (listed as "Parfum (Fragrance)") is the 16th of 29 ingredients.

Does No7 Prime Forever Serum contain alcohol?

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

Is No7 Prime Forever Serum safe for fungal acne?

It contains 2 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (isoamyl laurate); polysorbates (polysorbate 20). 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.
