Rough skin is mainly due to the lack of vitamins A, B2 and E. Without vitamin A, mucus and sebum secreted on the skin surface will decrease, and the resistance of skin and mucosa will decrease, which will cause skin dryness, desquamation, keratinization, protruding hair follicles and dullness. Lack of vitamin A can also lead to dry eyes, photophobia, excessive tears and blurred vision. Vitamin B2, also known as riboflavin, is one of the main substances that promote the redox of human cells. However, the lack of vitamin B2 will also have an impact on biological oxidation in the body, leading to obstacles in human metabolism, dry skin and desquamation, as well as angular stomatitis, blepharitis, glossitis, otorhinolaryngology and so on. In addition, the lack of vitamin E will also cause the problem of dry skin, and there will be fatigue of limbs, easy sweating, split hair, mental stress and so on. Vitamin E has the functions of maintaining skin elasticity, resisting cell membrane oxidation, preventing premature aging of skin cells, and supplementing skin's water-locking ability.
