Helianthus Annuus Seed Oil

Helianthus annuus (sunflower) seed oil is a non-volatile, non-fragrant plant oil commonly used as an emollient in cosmetic products. Naturally rich in linoleic acid—comprising about 60% of its makeup—this oil helps replenish moisture, strengthen the skin barrier, and soothe irritation. It also contains other beneficial fatty acids such as oleic, palmitic, stearic, and a small amount of omega-3 linolenic acid, all of which support skin health.

This oil is especially helpful for dry, dehydrated, or environmentally stressed skin. Its high linoleic acid content supports the skin’s natural ability to produce lipids like ceramides, essential for a strong barrier. As a result, it helps visibly restore the skin, leaving it smoother and healthier-looking.

In addition, Helianthus annuus seed oil has a naturally calming effect, making it effective in reducing signs of irritation or skin stress. Studies have even shown that when used on infants with atopic dermatitis, sunflower oil can serve as a gentle alternative to topical steroids for managing symptoms.
