Causes of dark skin

1. Do not pay attention to sun protection.

Not applying sunscreen is the direct cause of skin darkening, accounting for 90%. In the sun for a long time, the skin will activate tyrosinase, so that melanocytes produce melanin in large quantities, and at the same time produce free radicals to increase melanin.

2. Trace elements and heavy metals exceed the standard.

The skin care products or cosmetics used contain elements such as lead and mercury.

3. Accumulation of old skin keratin.

The accumulation of old keratin will make the skin look dull and yellow.

4. Moisturizing and moisturizing are not done properly.

If the moisturizing is not done properly, the skin will be dry, peeling, peeling, long fine lines, and the skin will become dull.
