About this ingredient
Phellodendron Amurense Bark Extract is an extract from the bark of the Amur cork tree. Its best-known component is berberine, an alkaloid with antioxidant and calming activity. In cosmetics it is used as a supporting ingredient for reactive and blemish-prone skin, in soothing and oil-control formulas. On efficacy it pays to stay sober. Berberine shows interesting effects in the lab, but topical clinical evidence that would justify an acne-treatment role is scarce. It works as a supporting active for comfort, not as a substitute for ingredients with solid backing against blemishes. For topical use in pregnancy and breastfeeding there are no clear risk signals at usual cosmetic concentrations. Systemic absorption from skin is low, so it can generally be used; if in doubt, check with a doctor. Tolerance is good. Low irritation and low allergy potential, compatible with sensitive skin. Most people see no reactions.
