Grape seed oil, also referred to as grapeseed oil or grape oil, is a vegetable oil obtained from grape seeds. It is a by-product of the winemaking industry and is typically employed for culinary purposes.
This oil is composed of around 70% linoleic acid, 16% oleic acid, and 4% stearic acid. It is characterized by its high content of polyunsaturated fats and low levels of saturated fat. Furthermore, grapeseed oil contains 0.8 to 1.5% unsaponifiable rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol). Although it contains some vitamin E, other oils like safflower oil, cottonseed oil, and rice bran oil have higher vitamin E levels. The moderately high smoke point of grapeseed oil, approximately 216°C (421°F), makes it suitable for various culinary applications, including salad dressings, mayonnaise, and infusions with herbs and spices. It is also commonly used in baked goods, pancakes, waffles, and as a coating for raisins to maintain their flavour.
Since grape seed oil is a lightweight oil extracted from grape seeds, it can quickly penetrate the skin, leaving it soft, supple, and well-hydrated.
Notably recognized for its antimicrobial and anti-inflammatory properties, grapeseed oil is rich in omega fatty acids and vitamin E, making it a popular choice in skincare formulations. Its molecular structure, including polyphenol compounds like proanthocyanidins, contributes to its strong antioxidant properties, making it effective in reducing signs of aging such as sunspots, fine lines, and wrinkles.
Grapeseed oil is particularly beneficial for addressing oily or acne-prone skin due to its high linoleic acid content, known for its anti-inflammatory properties. It can fortify the skin’s barrier, reduce water loss, and potentially aid in managing acne. However, individuals with acne-prone skin should use oils with caution.
The presence of antioxidants, minerals, vitamins, and fatty acids in grapeseed oil collaborates to fade dark spots, lighten scars, accelerate the healing process, and reduce the formation of keloid scars. Additionally, the inclusion of vitamin E, which is commonly found in eye creams, along with moisturizing fatty acids, can promote tighter and more youthful-looking skin.
Grapeseed oil also offers protection against sun damage and supports collagen repair, potentially diminishing the appearance of fine lines and stretch marks. Its antimicrobial properties contribute to deep cleansing, and it is mildly astringent with some antimicrobial properties attributed to polyphenolic compounds like catechins.
Furthermore, grapeseed oil is enriched with beneficial compounds such as beta-carotene, vitamins D, C, E, and polyphenols, endowing it with exceptional antioxidant abilities. These properties make it a potent source of antioxidants, capable of scavenging free radicals and shielding the skin from environmental aggressors like UV radiation and pollution. It is commonly incorporated into products designed for various skin types, including oily, acne-prone, dry, and hyperpigmented skin, and its use may lead to a more even skin tone.
While grapeseed oil is non-comedogenic, some believe its antimicrobial properties can be advantageous for treating acne, although further research is necessary to confirm this benefit. In general, grapeseed oil is well-tolerated by most individuals and can be used daily unless an allergy to the ingredient is present. Typically, it is employed as a moisturizer, applied after cleansing.
