Science
Mechanism of Action
This extract exerts its effects primarily as a powerful antioxidant, largely attributed to its anthocyanin content, which actively scavenges free radicals and mitigates UV-induced mitochondrial DNA damage. It also exhibits anti-glycation properties, critical for preserving collagen structure and reducing the appearance of wrinkles. Further mechanisms include promoting skin regeneration, demonstrating anti-inflammatory actions beneficial for soothing conditions like dermatitis, and offering skin brightening effects. Its anti-pollution efficacy is observed through the inhibition of intracellular reactive oxygen species (ROS) and inflammatory proteins triggered by particulate matter (PM). The extract has also been shown to increase fibroblast count and collagen thickness.

The Formula
Formulation
Stability
The primary active components, anthocyanins, are highly sensitive and prone to auto-oxidation, with their color and biological activity significantly impacted by pH, temperature, and light. Microencapsulation is a viable method to enhance their stability. While an optimal pH range of 4.1 to 5.8 was noted for a face mist formulation, the extract can be used in other topical products like lotions (pH 4.5-8.0) and gels (pH 6.2-6.6) with broader pH tolerances. Formulations that are excessively acidic or alkaline may cause skin irritation.
Safety
Safety Profile
Clitoria Ternatea Flower Extract is generally considered safe for cosmetic use and is recognized by the European Union. Topical application studies indicate it is non-sensitizing with a favorable dermal safety profile. However, individuals with sensitivities to natural plant extracts are advised to perform a patch test. While the flower extract (CTFE) exhibited phototoxicity at high concentrations, the flower water (CTFW) form showed a stronger safety profile. The European Food Safety Authority (EFSA) has expressed concerns about the safety of *ingesting* dried C. ternatea due to an unknown toxicological profile of cyclotides. Acute toxicity testing of the flower extract in albino mice did not show mortality or abnormalities. EWG Skin Deep rates this ingredient as 'LOW' risk for cancer, allergies/immunotoxicity, developmental/reproductive toxicity, and use restrictions.
