Flax seed extract
Flax seed extract is a gentle, nutrient-rich botanical ingredient derived from the seeds of the flax plant. Packed with omega fatty acids, lignans and antioxidants, it is commonly used in UK skincare and haircare to help soothe, hydrate and protect. It is a favourite in clean-beauty formulas for its calming and moisturising properties.
How it works in skincare
In cosmetics and skincare, flax seed extract functions as an emollient and skin-conditioning agent. Its high content of alpha-linolenic acid and other essential fatty acids helps reinforce the skin’s lipid barrier, reducing moisture loss while delivering a soft, supple feel. The natural lignans and polyphenols provide antioxidant benefits that defend against environmental stressors, making it a versatile addition to moisturisers, serums, masks and hair treatments.
