Cold showers do not lighten the skin.
Skin color has nothing to do with the temperature of the bath. Skin color is mainly related to genetics and race, and the amount of melanin synthesized by the melanocytes in the skin also has a role in the shade of skin color.
Skin whitening can be achieved through strict sun protection, dietary adjustments, and medical whitening techniques. Daily attention to sun protection, such as going out to wear sunscreen clothing, rub sunscreen and other methods to avoid prolonged exposure to the sun. Normally, you can also eat more fruits and vegetables containing vitamin C and vitamin E, such as kiwi, tomato, etc., which can inhibit melanin synthesis to a certain extent.
If necessary, you can take medical whitening technology, such as photorejuvenation, pigmented cosmetic laser spot removal, etc., to achieve the purpose of skin whitening.
Those who have whitening needs should choose reasonable whitening methods and go to regular medical institutions for consultation and treatment when necessary. Do not blindly use a cold shower to achieve the purpose of skin whitening, so as not to cause cold.
