The skin on the lower back turns black_What is the reason for the black skin on the lower back

People all want their skin to be fair and clean, so many people will take care of their skin. If the skin is exposed to the sun for too long, it will cause darkening. In addition, there are many other factors that can cause people's skin to darken. Some people notice that the skin on their lower back area shows obvious signs of darkening. So, what is the reason for the darkening of the skin on the lower back?

Why is the skin on the waist rough and dark?

More summer sunshine

The summer sun is terrible, but too much exposure to the summer sun is not a good thing, because the ultraviolet rays in the sun can stimulate the melanin in the skin, induce skin lesions such as freckles, and affect beauty. This refers to the summer sun.

Scrubbing bath - friction melanosis

Some people like to rub their skin vigorously when taking a bath, intending to wash it more cleanly. However, they do not know that rubbing too hard or repeatedly can also cause the skin to darken, which is called friction melanosis.

The mystery of friction melanosis has not yet been fully revealed, but its relationship with improper bathing has been confirmed by experts. It is mainly caused by mechanical stimulation such as strong friction pressure on the local skin. It often occurs in people who rub hard with bath towels or chemical fiber bath towels. It manifests as light brown to dark brown pigmentation in a diffuse reticular pattern, and is more common on bony protrusions such as the clavicle, ribs, scapula, elbows, and knees.

Food - the root cause of dark skin

Certain foods are also the root cause of skin darkening. Foods rich in metal elements such as copper, iron, and zinc have this disadvantage. This is because these metal elements can directly or indirectly increase the amount and activity of substances such as tyrosine, tyrosinase and dopaquinone that are related to melanin production. These foods mainly include animal liver, animal kidney, oysters, shrimp, crab, beans, walnuts, black sesame, raisins, etc.

Diet therapy for black waist and abdomen

Many reasons such as smoking, drinking, fatigue and illness can cause a circle of thick, dark aging marks to appear on the waist and abdomen. Especially for those who are used to wearing tight belts, dark circles often appear on their waist and abdominal skin due to long-term pressure affecting blood circulation. According to TCM's theory of internal organs and qi, when the spleen is deficient and the kidneys are deficient, the five internal organs' function of transporting and transforming qi and essence becomes disordered, which reduces the flow of qi and blood to the lumbar vertebrae and articular discs, and a rough and loose black skin circle forms on the waist and abdomen. The preventive and therapeutic measures are: insist on eating grains, vegetables, and fruits. The calcium, potassium, sodium, magnesium and other minerals contained in them are the most ideal foods for beautiful skin. Vitamin C is an essential component of the skin's interstitial matrix, and is essential for maintaining the permeability of lumbar blood vessels and the balance of pigment metabolism. The recipe of Polygonum multiflorum and rice porridge in traditional diet has the effects of replenishing qi and blood, improving skin tone, and benefiting the liver and kidneys. It is suitable for people with sore waist and abdomen, and darkening marks of aging. In addition, eating silkworm moths, young cicadas and other insects regularly also has good effects, because these foods contain more than 20 kinds of free amino acids, which are ideal substances for skin beauty.
