Linum Usitatissimum Seed Extract

This ingredient is also known as flaxseed extract. It has skin conditioning and perfuming properties.

Flaxseed naturally contains polysaccharides (sugars) and small amounts of fatty acid-related compounds to help hydrate the skin. The seed also contains antioxidants being studied for its effects on inflammation pathways.

A small clinical trial found topical flaxseed oil improved hand eczema over the course of 4 weeks. In an animal study, topical flaxseed cream supported wound-healing outcomes.

Overall, flaxseed is a great hydrating and barrier supporting ingredient. Like other plant extracts, some rare cases of allergic reactions can occur.

Though flaxseed has a perfuming function according to INCI, this doesn't mean the ingredient is added as a fragrance. It just means the material can contribute an odor or modify the scent of a formula.
