About this ingredient
Ascorbic acid polypeptide (same INCI name) is a vitamin C derivative bound to a peptide. It gives antioxidant action and supports a more even tone, with better stability than pure vitamin C, which oxidizes easily. On efficacy: as a family, vitamin C derivatives do work, though they tend to be gentler than pure ascorbic acid at the same concentration. It is a reasonable active for radiance and antioxidant defense. Data specific to this peptide form is still limited, so keep expectations realistic. During pregnancy and breastfeeding it is fine to use topically. Tolerance is good: low irritation and low allergy potential. It is kinder to sensitive skin than classic ascorbic acid, which can sting. An individual reaction is still possible but uncommon.
