Science
Mechanism of Action
This extract primarily functions by improving skin appearance and feel, contributing to a more hydrated and supple texture. Mechanistically, it can mitigate inflammatory responses by inhibiting TNF-α activity and bolster skin integrity through stimulating collagen synthesis. It also acts as an antioxidant, reducing oxidative damage within skin cells, and supports an even complexion by inhibiting tyrosinase activity, decreasing melanogenesis, and reducing melanin transfer.

Safety Profile
Generally considered safe for topical cosmetic application. However, rare instances of skin irritation, redness, allergic reactions, or contact dermatitis have been reported. A patch test is advisable prior to widespread use. Data on topical usage during pregnancy and breastfeeding is limited; consultation with a healthcare professional is recommended for these individuals. Concerns regarding plant toxicity (Cytisine in seeds) are related to ingestion, not topical application of the bark/leaf extract.
