Common questions

Is Simple Booster Serum 3% Hyaluronic Acid & B5 fragrance-free?

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

Does Simple Booster Serum 3% Hyaluronic Acid & B5 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 Simple Booster Serum 3% Hyaluronic Acid & B5 safe for fungal acne?

It contains 3 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (polyglyceryl-6 distearate, polyglyceryl-10 stearate); plant oils & butters (helianthus annuus seed oil). 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 Simple Booster Serum 3% Hyaluronic Acid & B5 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.
