Science

Mechanism of Action

This extract functions through several key components: Mucilages and flavonoids provide humectant properties, aiding in moisture retention and mitigating skin irritation and redness. Flavonoids contribute potent antioxidant defense against free radicals, thereby protecting against environmental oxidative stress and supporting anti-aging pathways. Tannins impart astringent effects, refining pores and promoting a smoother skin texture. Volatile oils offer antibacterial and antiseptic qualities, potentially benefiting blemish-prone skin. Furthermore, studies suggest it enhances skin cell metabolism by inhibiting enzymes such as tyrosinase, metalloproteinases, caspase, and elastase, while activating cathepsin, contributing to its comprehensive anti-aging profile and supporting skin elasticity. Animal studies also indicate a photoprotective capacity.

Stability

The bioactive compounds, particularly phenolic constituents, are susceptible to degradation from heat, light, and extreme pH conditions. Formulators should anticipate potential color changes, cloudiness, or precipitation during storage, though these typically do not compromise product quality but may necessitate filtration. For maximal stability, storage in closed containers, away from direct light and heat, within a temperature range of +8°C to +25°C, is advised.
