What is Linoleic + Linolenic Acid?
Linoleic acid and linolenic acid are essential fatty acids commonly found in plant oils. They are types of polyunsaturated fats, with linoleic being an omega-6 fatty acid and linolenic an omega-3 fatty acid.
These acids are important for maintaining healthy cell membranes and producing signaling molecules. While some studies suggest that they can benefit cardiovascular health, excessive intake, particularly of omega-6s, might lead to an imbalance that could be less beneficial.
When you see linoleic or linolenic acid on a skincare label, it may be included for its moisturizing properties or potential benefits to the skin barrier function.
Commonly found in: Skin Care, Dietary Supplements, Cooking Oils, Processed Foods
What to watch
- Excessive linoleic acid intake may disrupt the balance of omega-6 and omega-3 fatty acids in the diet.
Benefits
- Linoleic acid can help maintain healthy skin by supporting the skin barrier function.
- Linolenic acid is associated with cardiovascular benefits and inflammation reduction.
Linoleic and linolenic acids are generally recognized as safe (GRAS) when used as food ingredients.
While beneficial for essential functions, optimal intake ratios with omega-3s are still debated.
These acids are typically plant-derived and considered vegan-friendly.
