White Spots on the Skin, What Could They Be?


Dark spots usually get the most attention in dermatology, especially because of the concern for melanoma. Well what about white spots? Should they be of concern?

Today's blog post will review some of the more common white spots I get asked about as a board-certified dermatologist and what I suggest.

A special thank you to Detroit's own Fox 2 anchor Lee Thomas (pictured above) for helping to educate the community about vitiligo.

Happy #DermTipTuesday!

 

Post-inflammatory Hypopigmentation

What can cause this? Any condition that irritates or inflames the skin, such as eczema, seborrheic dermatitis, psoriasis, or traumatic injuries to the skin like cuts or burns. When the skin is injured, irritated, or inflamed, it will heal in one of two ways, become dark or light. The light discoloration is what is referred to as post- ("after") inflammatory hypo- ("under") pigmentation. The discoloration can take several months to resolve. Very rarely is it permanent.

Protect these areas from sun exposure at all times by wearing sunscreen with SPF 30 or above and protective clothing. Continue the sun protection even after it resolves.
