Common questions

Is No7 Laboratories Line Correcting Booster Serum fragrance-free?

Yes. No fragrance, essential oils or fragrance allergens are listed in its ingredients.

Does No7 Laboratories Line Correcting Booster Serum contain alcohol?

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

Is No7 Laboratories Line Correcting Booster Serum safe for fungal acne?

It contains 2 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (sorbitan 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.

Is No7 Laboratories Line Correcting Booster Serum suitable for sensitive skin?

Its ingredient list avoids the most common irritants: no fragrance, essential oils, drying alcohol or strong exfoliating acids are listed. Reactions are individual, so patch-test anything new.
