Eczema is an allergic irritant that causes localized skin erythema, papules, itching, erosions, and oozing. When eczema is treated, a hypopigmented white spot will form on the surface of the skin, which will gradually fade over time, usually taking about three months. This can be done without treatment, as it does not affect the body too much. If you feel that the whitening is slow to fade and you want to make it fade quickly you can choose to apply an immunomodulator locally, either with 0.1% tacrolimus ointment or with 1% pimecrolimus cream, which will make the whitening fade gradually after a period of continuous application. You can also choose to use skin tone masking agents, and there are many types of such skin tone masking agents, such as Gebranin. This can be applied to the surface of the white spots to quickly cover them, thus restoring self-confidence and beautifying the appearance of the skin.
