Castanea sativa Dried Fruit CO₂ Extract is a refined botanical extract obtained from the dried fruits (nuts) of the sweet chestnut using supercritical CO₂ extraction, a solvent-free method that preserves the integrity of sensitive bioactive compounds.

This extract is naturally rich in polyphenols, tannins, and antioxidant constituents, which provide astringent, protective, and conditioning benefits to the skin.
In cosmetic formulations, it is valued for its ability to help improve skin tone, support the appearance of firmness, and enhance overall skin comfort, particularly in products designed for stressed, tired, or environmentally exposed skin.

Thanks to its tannin content, Castanea sativa fruit CO₂ extract contributes to a gentle tightening and refining effect, making it suitable for formulations targeting:

- Loss of firmness.
- Skin prone to redness or superficial capillary visibility.
- Products designed to improve skin texture and comfort. 

Unlike Horse Chestnut (Aesculus hippocastanum), sweet chestnut does not act as a true venotonic, but it serves as an excellent complementary botanical, reinforcing cosmetic systems aimed at skin tonicity, antioxidant protection, and barrier support.

The CO₂ extraction process ensures a clean, stable extract with no solvent residues, ideal for premium cosmetic and dermocosmetic applications.

Typical cosmetic use level: 0.1 – 0.5%
