What they look like
Everyone has nevi. They appear in places where melanin accumulates, which is responsible for tanning. This is why moles appear on the body gradually. They can disappear or become more defined.
The shade of the skin and tumors on it vary depending on the number of melanins. The various black spots on a nevus are deposits of dark-colored pigments that are produced by melanocytes.
Melanin metabolism depends on the presence of the amino acid tyrosine, enzymes, the tone of the endocrine system, and the influence of external circumstances. The higher the activity of melanocytes, the greater the likelihood of various spots on the skin.
