Isomerized Linoleic Acid
Isomerized linoleic acid is a modified form of linoleic acid with rearranged double bonds that gives oils a lighter, more stable feel. Creams and serums use it for emolliency and a less greasy finish, though its targeted benefits aren't well established.

Our take
Is Isomerized Linoleic Acid a Good Ingredient?
Rated Fair because it offers emolliency and a lighter sensory profile, but solid clinical support for specific skin-corrective benefits is lacking. Being an unsaturated oil, it can also oxidize over time, which raises irritation potential and may congest acne-prone skin if the formula isn't stabilized, and that risk is what holds the rating down.
What it does
Skin Benefits
Provides a soft, conditioned afterfeel with a lighter finish; any oil-balancing or clarifying effects remain tentative due to limited evidence.
Where you'll find it
Uses in Skincare & Cosmetics
Used in facial oils, gel-cream moisturizers, and oil-control serums to impart slip while minimizing greasiness.
Before you use it
Safety
Generally tolerated, but oxidation byproducts may increase irritation; prefer formulas with antioxidants and observe shelf life. Acne-prone or very sensitive users should patch test new products.
