White spots on the skin are a result of hypopigmentation, which means that the skin cells are lacking and not producing melanin, a pigment responsible for skin colour. Hypopigmentation can be more difficult to treat than hyperpigmentation, a condition of dark spots caused by an abundance of melanin, but some methods may restore the natural skin colour.
Consult a dermatologist. If the white spots are not caused by scarring, a dermatologist can identify the condition, its cause and available treatments. Some white spots on the skin are caused by medical conditions. These include vitiligo, which causes a complete loss of pigment; pityriasis versicolor, a chronic fungal condition, and pityriasis alba, a form of eczema.
Avoid exposure to the sun. If the white spot is located in a sun-exposed area such as the face, neck or hands, use a high-strength sunscreen. Patients often think that exposing the white area to the sun will darken it. But the sun will increase the contrast between the spot and the normal skin and ultimately will cause more damage.
Don't look for quick fixes. For white spots to return to normal colour, the cells that aren't producing melanin need to be replaced with normal, healthy cells. The key is to trigger a healthy functioning of cells, which is a process. Simply lathering on a substance with a dye effect will do nothing to change the condition. However, you can try a tinted cosmetic cream such as a self-tanner to camouflage the spots while you're getting other treatments.
Ask your doctor about prescription steroid creams. They are the safest and simplest initial treatment, especially for vitiligo that is recently diagnosed or spreading. These creams may be used to treat other cases of moderate to severe hypopigmentation. The creams provoke the skin to produce melanocytes, which are cells that create melanin. The creams require multiple daily applications for three to six months. Side effects vary by brand and patient.
Purchase antifungal creams if you have pityriasis versicolor. This is a common skin condition caused by an infection of dead surface skin cells with a yeast fungus, which typically begins on the back. An antifungal cream can get rid of the yeast and restore skin colour within weeks once the dead cells are shed, according to BBC Health.
Address the root of the eczema problem if that is causing the white spots. There are many types of eczema, all of which require different, specific treatments. Your dermatologist can diagnose and treat the eczema type. When the eczema is under control, ask your dermatologist about correcting residual hypopigmentation.
Consider PUVA therapy, a combination of the oral drug psoralen and a high-intensity long-wave ultraviolet light. This is a common treatment for vitiligo patients. The American Osteopathic College of Dermatology reports that PUVA is effective in restoring some colour in more than half of treated patients, but total restoration of colour occurs in only 15 per cent to 20 per cent of patients. Treatment sessions are two or three times weekly. Even if they work, you probably won't see results for at least a few months.
Ask your dermatologist about laser resurfacing. A Dermatology News report on SkinTherapyLetter.com indicates that this treatment is effective for correcting hypopigmentation, including white spots on the delicate skin of the face. This is ironic given that white spots are a side effect of a cosmetic laser-resurfacing procedure used on dark-skinned patients.
