The Role of Linoleic Acid in Skin…ir Health: A Review.

Linoleic acid is an essential fatty acid that your skin needs to maintain its barrier and stay healthy. When applied topically, it may help repair damaged skin, reduce inflammation, support wound healing, and even stimulate hair growth—though most of this evidence comes from lab and animal studies, not yet from large human trials. People with acne, eczema, and psoriasis often have disrupted linoleic acid metabolism, suggesting it plays a real role in these conditions.
