Our take
Is Polyester-5 a Good Ingredient?
It rates Fair: it improves hold and transfer resistance, yet lacks strong clinical data for skin-improving effects. Some users may notice mild irritation or a tight, film-like feel, especially on compromised skin.
What it does
Skin Benefits
Keeps color looking fresher by limiting transfer and smearing. Creates a more refined surface so makeup appears neater and more polished.
Where you'll find it
Uses in Skincare & Cosmetics
Often included in lipsticks, tinted moisturizers, and nail topcoats to improve staying power and finish. Also found in brow gels and setting products for better fixation.
Before you use it
Low overall irritation potential, but sensitive skin may react to film-formers in leave-on products. Patch testing is advisable for delicate or irritated skin. No specific regulatory restrictions commonly cited.
