Buddleja Officinalis Flower Extract

Buddleja officinalis flower extract is derived from the flowers of the butterfly bush (Buddleja officinalis), a plant traditionally used in Chinese medicine. In skincare formulations, it functions as a UV filter—a compound designed to help protect skin from ultraviolet radiation.The extract contains natural phenolic compounds that contribute to its light-absorbing properties, which is why it appears in sun protection products and broader skincare formulations. It is relatively uncommon in mainstream skincare, appearing in approximately 0.1% of products.

Buddleja officinalis flower extract protects skin through two primary mechanisms. First, its phenolic compounds absorb ultraviolet light, converting it into heat and preventing it from penetrating deeper into the skin. Second, these same compounds exhibit antioxidant behaviour, helping to scavenge free radicals that form when skin is exposed to UV radiation and other environmental stressors.

This ingredient typically appears in sunscreens, moisturisers with UV filters, and antioxidant serums. Use products containing Buddleja officinalis flower extract as directed on the label. If using it as part of a sun protection routine, ensure your overall formulation provides adequate broad-spectrum coverage (SPF 30 or higher) and apply generously and regularly.

Buddleja officinalis flower extract is generally well-tolerated and considered safe for topical skincare use. Rare sensitivity may occur in individuals with allergies to plants in the Scrophulariaceae family.
