summary

Vitiligo is difficult to treat, I have been sick for more than a year, according to their own condition, systematic treatment, not only to use internal medicine, but also can not leave external medicine. Let's take a look at the external use of vitiligo.

What does vitiligo external medicine have

First: the occurrence of anti peroxidant vitiligo is mainly due to the decrease of melanin, so patients should avoid the damage of multiple melanocytes, and external anti peroxidants can inhibit the production of epidermal peroxide, eliminate excessive accumulation of hydrogen peroxide in the epidermis, reduce the damage of oxygen free radicals to melanocytes, and make melanocytes return to normal function, white spots recover Color.

Second: corticosteroid hormone preparations corticosteroid hormone preparations for the treatment of vitiligo or have a certain effect, at present, many hospitals will choose such drugs in the treatment. Because corticosteroids can reduce the skin reaction to inflammation, inhibit the infiltration of inflammatory cells and the synthesis and release of inflammatory mediators, inhibit the formation of autoantibodies, inhibit the mitosis of local lymphocytes, and reduce the number of B lymphocytes; Inhibit the release of cytokines, improve the stress ability of local tissue to harmful stimulation, inhibit the release of cytotoxic substances, improve microcirculation, promote the proliferation of melanocytes and melanin synthesis, so as to inhibit the abnormal immune inflammatory reaction of vitiligo lesions, prevent the progressive destruction of melanocytes, enhance its effect, and promote the production of leukoplakia pigment.

Third: photosensitizer is sensitive to light in patients with vitiligo, so it is necessary to avoid the damage of ultraviolet rays to the skin. Photosensitizer can enhance the photosensitive response of skin to ultraviolet rays, reduce the number of Langerhans cells in vitiligo lesions, regulate the immune response of local tissues, inhibit the progressive destruction of melanocytes by autoantibodies, promote the DNA replication of melanocytes, and improve the quality of skin It can activate the proliferation of the non functional melanocytes in the melanocyte reservoir of the outer root sheath of hair follicle, promote their differentiation and maturation and migration to the epidermal cells, so as to regenerate the pigment in the leukoplakia.
