Although it is mainly popular in the food industry, it has been gaining traction in the cosmetic industry as well. It is a non-greasy oil known for its moisturizing properties.
Hazelnut oil has a similar fatty acid content as olive oil. It contains a high oleic acid content. It can be used like olive oil in skincare products (2). Read on to know its complete nutritional profile and benefits.
Hazelnut Nutrition Composition And Benefits
- Fatty acids play a role in balancing the skin’s protective barrier (5). They also prevent the loss of moisture from the skin’s surface. These fatty acids prevent any harmful substances from entering the skin.
- Vitamin C (ascorbic acid) prevents and repairs photo-aging. It has antioxidant properties that protect the skin from UV damage (6), (7) (8). It can also be used to reduce hyperpigmentation. Vitamin C has anti-inflammatory properties and can help treat skin conditions like acne and rosacea. It also promotes wound healing and boosts collagen synthesis.
- Vitamin E contains tocopherols and tocotrienols. It has high antioxidant properties that reduce free radical damage due to solar radiation (9). It protects the skin from oxidative stress. It helps prevent sunburn. It has therapeutic effects against psoriasis, acne, scleroderma, and atopic dermatitis. It can also promote wound healing. It might reduce the signs of sun damage, including skin thickening, wrinkling, and erythema (10). Tocopherols also have skin-conditioning properties (11)
- Folic acid improves skin firmness that may otherwise deteriorate due to aging (12). Folic acid supplementation is often used to treat chronic inflammatory skin conditions (13).
- Vitamin A (retinol) is often used in the treatment of acne, psoriasis, and other skin conditions (14). It also slows down the aging process. It protects the skin barrier functions and collagen, and reduces water loss. It also prevents the discoloration of the skin. It reduces excess sebum production, improves skin elasticity, and boosts collagen synthesis and keratin formation. It reduces the signs of aging and photoaging too (15). Research shows that vitamin A can reduce fine lines and wrinkles effectively (16).
- Niacin improves the skin barrier function (14). It prevents water loss and increases the moisture content in the skin. It improves skin quality and reduces wrinkles. It may help treat skin conditions like acne and rosacea, thanks to its anti-inflammatory properties. It reduces the effects of aging and might also reduce skin discoloration.
- Minerals like zinc and copper offer photoprotective properties and prevent damage from UV radiation (15). These minerals prevent the radiation from penetrating the skin. They also have antioxidant properties. Copper, additionally, improves skin elasticity and thickness.
