Four seasons skin care, spring: in spring, people's skin pores are unobstructed, metabolism is accelerated, and sebum secretion is vigorous, so the skin will appear vibrant and moist. Because the seasons alternate, clothes are reduced, and skin is aggravated by ultraviolet radiation, which easily leads to vitiligo. Summer: skin pores expand, blood flow speeds up, and the face is prone to congestion. In addition, strong sunlight can easily lead to skin burns, inflammation, vitiligo and even aggravate the condition. At the same time, sweating is more in summer, sweat pores are easily blocked, and skin diseases such as miliaria and summer dermatitis are frequent. Therefore, special attention should be paid to skin care in summer and sun protection measures should be taken when going out. Autumn: It's cool in autumn. Compared with summer, capillaries and sweat glands atrophy, sebum secretion slows down, and the skin gradually becomes dry and even rough and desquamate. Therefore, patients with vitiligo in autumn should prevent dry skin and pay attention to moisturizing and water retention. Winter: In winter, the wind is cold and the weather is cold. The patient's skin pores and sweat glands are easily blocked, the blood flow rate is slow, and the metabolism slows down. The skin often appears dry, itchy and even frostbite. Therefore, the focus of skin care in winter is mainly cold protection and skin care. Keep warm to prevent frostbite.
