Kayaflavone is primarily used in skincare and cosmetic formulations due to its anti-inflammatory and antioxidant properties. It helps reduce redness and soothes irritated skin, making it suitable for sensitive and acne-prone skin types. Its ability to neutralize free radicals contributes to anti-aging products by supporting skin elasticity and reducing the appearance of fine lines. Additionally, kayaflavone is investigated for its potential in treating hyperpigmentation, as it may inhibit melanin production, leading to a more even skin tone. It is commonly found in serums, moisturizers, and brightening creams. Research is ongoing into its use in pharmaceuticals for its possible antimicrobial and cell-protective effects.
