Why Do You Get White Spots On Skin After Tanning?

Q: What causes uneven tan?

A: You get even tan thanks to melanin, i.e. pigment or substance, produced by melanocytes (specialized skin cells). They let skin enjoy the sun and acquire beautiful skin tone, darker than your natural skin tone. However, not all melanocytes succeed with this goal. When their work is impaired, normal production of melanin isn’t possible, so you are getting uneven tan with some areas lighter than others.

Q: Why do some areas of my skin remain white after tanning?

A: Because specialized skin cells melanocytes produce no pigment (melanin) in these areas due to specific skin diseases, such as vitiligo or pityriasis versicolor.

Q: If white spots on skin after tanning appear mainly on my face and hands, what can it be?

A: Chances are high you are dealing with vitiligo, a skin disease that hasn’t been studied thoroughly yet. Organism poisoning or disorders of nervous system may trigger vitiligo in some people.

Q: When white spots occur on any skin areas, exposed to sun, not only face and hands, what can it be?

A: It’s likely to be pityriasis versicolor. In the beginning it starts as flaking skin and itching. In a while after tanning you are getting white spots.

Q: Why does pityriasis versicolor develop?

A: It may develop because of organism’s intolerance to high temperature or increased air humidity. When skin is exposed to sun, healthy skin cells produce melanin, while cells, affected by pityriasis versicolor, don’t pass sunlight through and remain white.

Q: Can pityriasis versicolor pass by itself without treatment?

A: No, it can’t. You need to consult a dermatologist. The disease may develop into a chronic form and become acute during prolonged sun exposure.
