Summary

Antioxidant Astringent Soothing Moisturizer Antibacterial Oil Control Collagen Booster

Science

Mechanism of Action

Quercus Alba Bark extract operates as an effective astringent, gently constricting skin pores and tightening tissues through protein binding, which can assist in drying out irritated areas. It calms the skin by mitigating redness and inflammation through the inhibition of inflammatory compound release. Functioning as an antioxidant, it neutralizes free radicals, safeguarding the skin from environmental stressors. Additionally, it possesses antibacterial qualities by interacting with proteins essential for bacterial proliferation, aids in sebum regulation and skin cleansing, promotes a more even skin tone, and supports collagen production for enhanced skin volume and elasticity.

Generally regarded as safe for short-term topical application, typically for 2-3 weeks. However, comprehensive long-term safety data is limited. Topical use may induce skin irritation or exacerbate existing conditions like eczema, particularly on broken skin. Due to the potential for individual allergic reactions or sensitivities, a patch test is advised, especially for those with sensitive skin. There are concerns regarding systemic use in individuals with impaired kidney or liver function, but these do not directly apply to topical cosmetic use unless absorption is significant.
