A toning plant extract. Safe.
Cinchona Succirubra Bark Extract is the extract of cinchona bark, which contains alkaloids such as quinine along with tannins. In cosmetics it appears mainly in hair products and scalp lotions, where it gives a toning, fresh sensation. On efficacy: it works as a supporting ingredient. Claims about stimulating hair growth or strengthening the root are traditional and marketing-led; solid clinical evidence is thin. It provides astringency and a clean feel, little more. Topical use during pregnancy and breastfeeding is fine at usual cosmetic levels. Tolerance is good, with low irritation and allergy potential. Suitable for sensitive skin. As with any botanical extract, a patch test is reasonable if your skin reacts easily.
