Linum Usitatissimum Seed Oil
What is Linum Usitatissimum Seed Oil?
Linum Usitatissimum Seed Oil is extracted from the seeds of the flax plant, Linum usitatissimum, a herbaceous annual native to regions like the Mediterranean and Asia. This pale yellow to golden oil consists primarily of triglycerides rich in polyunsaturated fatty acids, notably alpha-linolenic acid (an omega-3), alongside oleic and linoleic acids. In cosmetics, it falls under emollients and skin-conditioning agents. It functions by mimicking the skin's natural lipids, creating a semi-occlusive film that reduces transepidermal water loss while allowing skin to breathe. This makes it suitable for incorporation into moisturizers, facial oils, serums, and balms, where it softens texture, enhances spreadability, and imparts a lightweight feel without greasiness. Its composition also supports delivery of lipid-soluble compounds deeper into the stratum corneum.
