Frequently asked questions
Does One Step Moisture Up Pad contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 2 of the EU-labelled fragrance allergens: citrus aurantium bergamia fruit oil, citrus limon peel oil. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat One Step Moisture Up Pad with caution and patch test before full use.
Is One Step Moisture Up Pad paraben-free?
