Frequently asked questions
Does Hydro Boost City Shield Water Gel SPF 25 contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 1 of the EU-labelled fragrance allergens: parfum. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Hydro Boost City Shield Water Gel SPF 25 with caution and patch test before full use.
Is Hydro Boost City Shield Water Gel SPF 25 paraben-free?
