About this ingredient
Diacetyl Boldine is an acetylated derivative of boldine, a plant alkaloid with antioxidant action. Its INCI is Diacetyl Boldine. It is included in formulas on the idea of evening out tone and protecting against free radicals. The maker links the ingredient with a more even tone, but independent data are sparse. View it as a supporting active with a modest evidence base: it may add to a formula's antioxidant action, without expecting a marked change from it alone. Topically it has no systemic relevance, so it can be used during pregnancy and breastfeeding. Tolerance is good and irritation and allergy risk are low. It suits sensitive skin and is not comedogenic, so it fits oily or acne-prone skin too.
