What does dark knee color mean

The knees of young people are pink and tender, while those of older people fade slightly as they age. It is normal for the knees to turn white or for the stratum corneum to thicken, but now many people's knees are dark in color and have not experienced anything. This may be due to pigmentation or frequent bumps, which cause the color of the knees to darken.

Problem Analysis: Hello, this situation may be caused by melanin deposition or bumps. Pay attention to rest at ordinary times and try not to do strenuous exercise.

Guidance and suggestions: If there are no pain or discomfort symptoms, it is generally not a big deal. Pay attention to applying hot compresses to relieve pain and discomfort. If necessary, it is recommended to go to the hospital for an X-ray examination to determine the cause and receive symptomatic treatment.

During the pigment metabolism of human skin, tyrosinase catalyzes tyrosine conversion to dopaminaldehyde and finally forms 5,6-quinone transposase, which constitutes the main component of melanin in the melanocytes in the basal layer of the human epidermis. Therefore, effective ingredients that regulate the activity of tyrosinase such as placental hydrolysate, liver hydrolysate, umbilical cord hydrolysate, egg yolk extract, etc. are used in anti-freckle cosmetics.

Substances that change the melanin production pathway, such as glutathione, kojic acid, arbutin, and vitamin C, can also be used to remove spots. The effective ingredients that inhibit the formation of melanin cells are: chloroquine, indomethacin, vitamin C, 9-carotene, green tea, kojic acid, melanin, ebony, cinnamon, licorice oil, and soluble extracts. So how to prevent the production of melanin and make the skin darker?

1. Pay attention to labor protection and avoid direct exposure to sunlight. Ultraviolet rays can promote melanocytes to produce melanin particles, making the skin darker. It is best to apply some whitening sunscreen on the exposed areas.

2. Pay attention to your diet. Usually, you should drink more water, eat more fresh vegetables, hawthorn, carrots, and eat less salt to reduce the formation of melanin.

3. Take vitamin C orally, which can reduce dopaquinone to dopa, thereby inhibiting the formation of melanin.
