What causes dark spots on the back?

Studies have found that there are both internal and external reasons for dark spots on the back, such as stressful daily work, irritable mood, irregular work and rest time, long periods of sitting, long-term use of birth control pills, etc. In addition, long-term exposure to the sun and direct ultraviolet rays will cause melanin precipitation and the appearance of dark spots. It can be seen that if you want to reduce melanin, you must do a good job of sun protection.

1. What are the causes of back spots?

The reasons for spots on the back can be divided into internal and external aspects. Some women are easily irritable due to the stress of daily work, family chores and other factors; some women have very irregular work and rest time and lack of exercise; and some women take birth control pills all year round, which can cause spots on the back.

Sunburn is also the main cause of back spots. When people apply sunscreen, they can cover the front of the body thoroughly, but they are often unable to cover the back. This is because after being exposed to direct sunlight, melanin will precipitate and spots on the back will appear.

Pityriasis versicolor on the back is a common disease in summer. People sweat easily in summer. When we sweat a lot, a bacteria called "Pityrosporum fumigatus" can easily damage our skin. This bacteria likes warm and humid environment, so the back becomes a large greenhouse where the bacteria gather, causing pityriasis versicolor on the back.

2. How to remove dark spots on the back?

1. Do a good job of sun protection. Ultraviolet rays in the sun are one of the causes of freckles. They make latent melanin active and slowly turn it into small spots. Apply sunscreen before going out. When the sun is strong, hold an ultraviolet-proof umbrella or wear a sun hat to block the sun's rays on your face as much as possible.

2. Don’t neglect after-sun repair. Even though you have made sun protection preparations, there will always be omissions, and then you will need to do post-sun repair work after returning home. In addition to applying repair cream, remember to moisturize your facial skin.

3. Use less cosmetics. Cosmetics contain heavy metals such as mercury, lead, and arsenic. They can make you look radiant and dazzling after putting on makeup, but the price behind this beauty is the gradual deterioration of skin quality. The heavy metals that penetrate into the skin will also induce and aggravate the deposition of melanin in the deep layers of the skin, making the spots more and more numerous and obvious. Therefore, try not to wear makeup. If it is unavoidable, remember to remove makeup carefully.

4. Eat more beauty-enhancing foods. Many foods are beneficial for nourishing the skin. For example, tomatoes contain glutathione which can inhibit melanin, carrots are rich in carotene which can scavenge free radicals and resist oxidation, and vitamins C and E are all good helpers for beauty.
