KOUSOU

Description

KOUSOU, derived from the Japanese silk tree (Albizia julibrissin), is an innovative ingredient gaining traction in advanced skincare formulations. This botanical extract is rich in flavonoids, particularly quercetin and isoquercitrin, which contribute to its potent antioxidant properties. KOUSOU has demonstrated remarkable efficacy in protecting skin cells from oxidative stress and environmental aggressors.

Research indicates that KOUSOU can stimulate collagen production and inhibit collagenase activity, potentially reducing the appearance of fine lines and wrinkles. Its anti-inflammatory properties make it particularly beneficial for sensitive and reactive skin types. KOUSOU has also shown promise in regulating sebum production, making it a valuable ingredient for acne-prone skin.

In skincare formulations, KOUSOU is typically used at concentrations between 0.5% to 2%. It is compatible with a wide range of cosmetic ingredients and can be incorporated into various product types, including serums, moisturizers, and masks. KOUSOU's stability in formulations is generally good, but it may be sensitive to high temperatures and extreme pH levels. When properly formulated, KOUSOU can contribute to improved skin texture, enhanced radiance, and overall skin health.
