Antioxidants
Sweet Chestnut (Castanea sativa) seed extract is a natural ingredient derived from the seeds of the sweet chestnut tree, typically using gentle water- or alcohol-based extraction methods to preserve the active compounds. This extract possesses antioxidant properties due to the presence of flavonoids and tannins, which help protect the skin from harmful environmental influences and free radicals. Furthermore, it may have moisturizing and soothing properties, making it frequently found in products designed for sensitive, dry, or irritated skin. The sweet chestnut, long valued for its medicinal properties, originates from Europe and the Mediterranean region and is cultivated sustainably to preserve the natural environmental balance.

Another feature of this exceptional extract is its ability to promote microcirculation. This is an important advantage, especially if the goal is to revitalize tired, grayish, or dull skin. By strengthening blood circulation, the skin receives more oxygen and nutrients, which naturally improves its tone and texture.
Security Information
This ingredient, extracted from chestnut seeds, is considered safe for use in many cosmetic products. Its safety profile is confirmed, as there are practically no cases of serious side effects or allergic reactions. However, as with any product, individual sensitivities may occur, so it is recommended to carefully monitor skin reactions. Depending on the product, the concentration of this extract may vary, so it is important to follow the instructions for use and not use overly concentrated forms. Regulatory authorities, such as the European cosmetics regulation system, recognize this ingredient as suitable for use in cosmetics, and its use complies with safety standards, ensuring that consumers can feel safe using products that contain it.
Sustainability and Extraction
Chestnut seed extract is a natural ingredient that, depending on cultivation and production practices, can have a high level of sustainability. Sweet chestnut trees are typically grown in European and Mediterranean regions, often on traditional, low-impact farms. These trees are long-lived and do not require intensive care, which reduces the risk of soil degradation or excessive pesticide use. In addition, their cultivation helps maintain biodiversity, as chestnut groves naturally attract various species of insects, birds, and other organisms. Extraction processes, if carried out responsibly using water or low-energy technologies, can also be relatively environmentally friendly. However, challenges arise when the ingredient is produced on a large scale: intensive farming techniques that harm ecosystems may be used, or cheaper, chemical extraction technologies that contribute to pollution. From a social perspective, if chestnuts are grown by small farmers, it can provide economic benefits to local communities, but it is important to ensure fair wages and working conditions for those involved in their collection and processing. Therefore, as with any natural ingredient, the level of sustainability depends heavily on the transparency of the supply chain and the responsible approach of the producers.
Products
You will find this ingredient in various cosmetic products designed to soothe, moisturize, or restore the skin. Face creams, such as those in the Sensibio AR skincare line, often use chestnut extract to combat redness or sensitivity. It is also a common component in Korean brands, such as Dr. Jart or Innisfree, where it is found in serums and essences formulated for tired or dehydrated skin. Body lotion manufacturers, like L’Occitane, also value this extract for its ability to soften and revitalize the skin. In hair care products, such as shampoos or conditioners, for example, in the Kérastase or Ryo lines, this ingredient is used to reduce scalp sensitivity and promote hair root strengthening.
