Question

The sunflower plant bears bright yellow flowers that always face the sun, hence the name. However, the plant is grown not only for its beautiful flowers, but also for its oil that has a host of health benefits. Sunflower oil prevents diseases, lowers cholesterol levels, keeps the heart healthy, and even prevents certain forms of cancer. Sunflower oil is a kind of “magic oil” when it comes to skin care, as it makes your skin soft and smooth, and prevents signs of aging. So, let us know more about its effects on your skin.

1. It Acts as an Effective Emollient(润肤霜).

Sunflower oil is an effective emollient, which means that it helps the skin retain moisture. Thus, people with dry skin can benefit immensely from the regular use of the oil. Also, it is mild, and provides relief from irritation and inflammation of the skin.

2. It Offers Sun Protection.

Sunflower oil is a rich source of vitamin E. The high vitamin content prevents the sensitive cells of the skin from being damaged by the ultraviolet (UV) rays of the sun.

3. It Prevents Earlier Aging.

Vitamin E present in sunflower oil not only protects the skin from sun damage, but also from earlier aging. What’s more, regular use of sunflower oil can reduce wrinkles and make one look younger. Also, sunflower oil is rich in antioxidants(抗氧化物质) that keep the skin fresh.

4. It Prevents Skin Infections（感染）.

Sunflower oil is a rich source of essential fatty acids that protect the skin from bacterial infections. Hence, it gives you a healthy skin.
