How it works in skincare

In cosmetics flax seed oil works as an emollient and skin-conditioning agent, delivering essential fatty acids that reinforce the skin’s natural lipid barrier and help reduce moisture loss. Its lightweight texture allows it to penetrate easily, leaving skin feeling soft and supple without greasiness. In haircare it smooths the cuticle and adds shine while calming an irritated scalp.
