Frequently asked questions
Does Tri-Acid Renew Skin Renewal Concentrate contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 2 of the EU-labelled fragrance allergens: parfum, geraniol. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Tri-Acid Renew Skin Renewal Concentrate with caution and patch test before full use.
Is Tri-Acid Renew Skin Renewal Concentrate paraben-free?
No parabens were detected in Tri-Acid Renew Skin Renewal Concentrate'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 Tri-Acid Renew Skin Renewal Concentrate suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Tri-Acid Renew Skin Renewal Concentrate contains 2 flagged allergens 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 Tri-Acid Renew Skin Renewal Concentrate against your own profile.
