How to treat dull and yellow skin? My skin is always dull and yellow. Do you know the root cause?

Why does the skin become dark yellow? With the development of economy, people's pace of life is accelerating and environmental pollution is becoming more and more serious. Our skin is also affected by external stimuli and endocrine effects, resulting in many people now having dark yellow skin and lack of luster.

1. Poor rest and lack of sleep

The sleep time at night is the most active time for skin cell renewal. If you go to bed too late or do not get enough sleep, the metabolic function will no longer be smooth, causing the aging stratum corneum to thicken, leading to dark yellow skin, loss of skin transparency, and a grayish color.

2. Ultraviolet sunburn type

Yes, you have read it 100 times in beauty books, but it still needs to be emphasized: resist ultraviolet rays and reduce the formation of melanin! UVB will tan the skin, while UVA will penetrate into and damage the dermis, invading collagen fibers and causing them to deteriorate. The UVB rays will remain in the dermis and form lumps, causing the skin to become dark and yellow. The skin will lose its translucency and become yellowish and dull. Therefore, no matter what skin type you have, if you want to whiten your skin, you must do a good job of sun protection.

3. Smoking type

The "smoke pollution" of cigarettes will cause a large number of free radicals in the skin, which will affect the blood and lymph circulation. Skin toxins cannot be effectively discharged, which will make the skin look yellow and may also cause pigmentation.
