For inducing the repigmentation of the skin, phototherapy ways are also put into use either alone or with the mixture with hydrocortisone-type compounds and these forms of therapy consisting of slender-band ultraviolet B (UV-B) light, excimer laser and PUVA (Psoralen plus UV-A).
Around seventy five percent of the patients who experience PUVA therapy respond a bit. But even for these persons, an utter repigmentation hardly ever happens. After the starting of 2 to 3 weeks of the contact to sunlight, patients would appear worse as the contrast between the pale and suntanned skin rises. By the passage of time, the repigmentation starts and the look of the skin will get better. In winter, if therapy discontinues many would be retaining half of the color they got during the summer time.
The ones affected by Vitiligo should be more cautious about protecting their skins against too much sun exposure being clad with protective outfits and keeping out of the reach of the sun and applying sunscreen lotions, etc.
In order to protect the eyes, the sunglasses designed specially for this purpose laced with the protective lenses have to be worn while being under the rays of sun.
