The neck is black and can't be washed clean. What should I do?

You can apply some beauty products, such as sunscreen and liquid foundation, to make it look white and delicate. If you want to treat both the symptoms and the root causes, you can refer to the following methods:

1, sun protection: sun protection can be divided into physical sun protection and chemical sun protection. Physical sun protection is the usual measures such as sun umbrella, sun hat, mask and sunglasses. Chemical sunscreen is to block ultraviolet rays by applying sunscreen.

Many people may not know much about sun protection. In fact, the ultraviolet rays emitted by the sun are very strong, which will accelerate the aging of facial skin and the direct loss of water. Therefore, fairies who love beauty must do a good job of sun protection. As long as you go out, you must wear sunscreen, and also on cloudy days, because there are ultraviolet rays on cloudy days.

2, diet: the skin is yellow and black, eat more fresh fruits rich in vitamin C in the diet, especially cucumbers, strawberries, tomatoes, oranges and so on. A large amount of vitamin C can help reduce melanin, prevent black spots and freckles, and make the skin more shiny and healthy. Eat less animal liver, beans, peaches and other foods, because the copper or zinc contained in these foods will make the skin black.

In addition, sensitive foods such as celery, fennel, white radish and coriander should also be eaten less, which will lead to dark spots on the skin after exposure to the sun.

3, diligent bathing: the purpose and role of bathing during the day and bathing at night are different. Taking a bath during the day, most people choose to take a bath in the morning, which can wake up the sleeping body and make the day full of vitality. Take a bath at night, come back from the outside, wash away all the dust and fatigue, and then enjoy sleep in the most comfortable position.
