Omega 3 Fatty Acids
Omega 3 fatty acids are essential lipids celebrated in skincare for their ability to nourish, strengthen and calm the skin. Found in many premium moisturisers, serums and hair treatments, they help restore the skin’s natural barrier and improve softness and resilience.
How it works in skincare
In cosmetics, omega 3 fatty acids work by integrating into the intercellular lipid matrix of the stratum corneum, reinforcing the skin’s protective barrier and reducing transepidermal water loss. Their anti-inflammatory properties help soothe redness and irritation while supporting a healthy, supple complexion and improving the overall feel and appearance of both skin and hair.
