CAS# 84604-20-6

Milk Thistle Seed Oil is cold pressed from the seeds of the Milk Thistle Plant (Silybum Marianum) which we commonly see throughout the land in the summer months.  Milk Thistle Seed Oil is an excellent source of silymarin, a complex of bioactive compounds consisting of a mixture of flavonolignans, including silybin, isosilybin,  silydianin,  and silychristin that are known for their antioxidant and anti-inflammatory properties.

In skincare products, silymarin is believed to help protect the skin from environmental stressors, such as UV radiation and pollution, which can cause oxidative damage and premature aging. Silymarin also has anti-inflammatory properties, which can help soothe and calm the skin, reducing redness and irritation.

Overall, the high silymarin content of Milk Thistle Seed Oil makes it an excellent ingredient for cosmetic formulations, particularly those designed to protect and nourish the skin. When used in combination with other natural and effective ingredients, Milk Thistle Oil can help create skincare products that promote healthy, youthful-looking skin.
