Body fluids contain up to 72% water, while the average adult contains 58-67% water.When the body's water content decreases, this can lead to dry skin, reduced sebum production, and loss of skin elasticity, even causing wrinkles.To ensure adequate water intake, teenagers typically drink around 1200 ml per day.Consume foods rich in Vitamin E.

Eating plenty of Vitamin E can improve rough skin.

Vitamin E plays an important role in preventing skin aging and maintaining smooth, supple skin.Japanese researchers have found that Vitamin E is important for anti-aging skin because Vitamin E can break down free radicals and remove them from the body, thereby inhibiting aging.Vitamin E also prevents the accumulation of lipofuscin in the skin.Scientists have discovered that:The formation of lipofuscin is related to the oxidation of lipids, and Vitamin E can prevent the oxidation of lipids.Foods such as cabbage, sunflower oil, and rapeseed oil contain varying amounts of Vitamin E. To compensate for the lack of Vitamin E in daily diets and to maintain healthy skin, it is recommended to supplement with Vitamin E-rich foods.
