Frequently asked questions

Does One Step Original Blemish Pore Clear Pad contain fragrance allergens?

Yes — analysing the INCI list, AllerNote found 2 of the EU-labelled fragrance allergens: limonene, citrus aurantium dulcis peel oil. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat One Step Original Blemish Pore Clear Pad with caution and patch test before full use.

Is One Step Original Blemish Pore Clear Pad paraben-free?

No parabens were detected in One Step Original Blemish Pore Clear Pad's listed ingredients. Worth keeping in perspective: parabens are among the least common cosmetic allergens, so "paraben-free" matters far less for reactive skin than avoiding fragrance or the preservative MI/MCI.
