Frequently asked questions
Does Slow Aging Astaxanthin Serum Drops contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 11 of the EU-labelled fragrance allergens: parfum, citral, coumarin, geraniol, limonene, linalool, alpha-terpinene, citrus aurantium peel oil, linalyl acetate, pinene, terpineol. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Slow Aging Astaxanthin Serum Drops with caution and patch test before full use.
Is Slow Aging Astaxanthin Serum Drops paraben-free?
No parabens were detected in Slow Aging Astaxanthin Serum Drops'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 Slow Aging Astaxanthin Serum Drops suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Slow Aging Astaxanthin Serum Drops contains 7 flagged allergens and 6 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 Slow Aging Astaxanthin Serum Drops against your own profile.
