Skin areas, affected by scarring or scar conjunctive tissue don’t contain melanocytes either. That’s why scars don’t get any tan, same like skin areas, affected by vitiligo.
Both conditions (vitiligo & scarring) don’t present any dangers for life. White patches on skin in this relation rather turn into a cosmetic problem. If it really bothers you, firstly, you shouldn’t sunbathe and, secondly, visiting a dermatologist will help to determine what’s exactly going on with you.
# 3 Pituriasis Versicolor
This kind of white spots on skin looks inhomogeneously: some are whitish, others are pinkish. Contrasts between different skin areas become more visible after sun exposure. This skin condition has fungal origin. Yeast Malassezia affects corneal layers of epidermis and pilar part of skin. Here yeasts live and propagate. A part of their ferments, azelaic acid, affects melanocytes so that they can’t produce melanin anymore. Since pigment disappears gradually, spots vary in hue – pink through white. Let’s look at such spots’ characteristics in greater detail:
- Tiny light spots on skin first appear on your back and you normally don’t notice them yourself.
- Later they occur also on chest, neck, armpits, shoulders; sometimes slight lymph nodes inflammation joins up.
- Visually they have distinct borders.
- The color is rather dark brown than white, but after sun exposure they change to the opposite.
- People with light skin before going to beach may be unaware of their skin problem, it becomes evident only after sun exposure.
- No inflammation but white spots are flaky.
