What is Linoleic acid?
Linoleic acid, also known as LA, is one of the immensely popular omega-6 fatty acid and natural occurring in the skin. You can expect to find large levels of this fatty acid outer layer of the skin, called the epidermis and performs the important task of preserving the structure of the skin and promoting ceramides enabling the skin’s protective barrier to function correctly. When topically applied to any skin type, dry or blemish-prone skin types will benefit from the repairing properties of linoleic acid not to mention its ability to reduce any hyperpigmentation by blocking melanin that develops in the lower layers of the skin as a result of sun exposure and other free radical damage. Dark spots and acne scarring will become less visible to the naked eye and the skin’s barrier remains rejuvenated and repaired.
