Frequently asked questions
Does Hyseac New Skin Anti-Blemish Booster Serum 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 Hyseac New Skin Anti-Blemish Booster Serum with caution and patch test before full use.
Is Hyseac New Skin Anti-Blemish Booster Serum paraben-free?
No parabens were detected in Hyseac New Skin Anti-Blemish Booster Serum'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.
Is Hyseac New Skin Anti-Blemish Booster Serum suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Hyseac New Skin Anti-Blemish Booster Serum contains 1 flagged allergen and 2 irritants (listed in the analysis above). If none are on your personal allergen list it may suit you, but patch test first — add your allergens to AllerNote to check Hyseac New Skin Anti-Blemish Booster Serum against your own profile.
