In the episode1, we introduced Tea Shield®, a sustainable and functional cosmetic ingredient derived from tea seed pericarp.
One of the key features of Tea Shield® is its ability to support skin barrier function.
In this episode, we will take a closer look at this barrier function and the scientific evidence behind the efficacy of tea seed pericarp extract.
1．What Happens When the Skin Barrier Function Weakens?
The skin’s barrier function protects against external irritants and retains moisture. When this function weakens, skin becomes more sensitive to external irritants, potentially resulting in dryness, itching, or redness, and may lead to skin irritation and inflammation.
2．Skin Barrier Function Efficacy with Tea Seed Pericarp Extract
When Tea Seed Pericarp Extract was added to a 3D-cultured skin model with weakened barrier function, a significant increase in TEER value, an indicator of skin barrier function, was observed. This confirmed the skin barrier function improvement of Tea Seed Pericarp Extract.
