Why do I get white spots on my skin in the summer and how can I treat them? A dermatologist answers

moderatoron

  • Sun exposure over many years (it’s most common on sun-exposed skin)

  • Natural aging – the spots become more common as we get older

  • Genetics – some people are simply more prone to them

Is it harmful?
No. IGH is completely harmless. It doesn’t turn into skin cancer, doesn’t spread to other people, and doesn’t affect your overall health. It’s purely a cosmetic concern.

Other Possible Causes of White Spots

While IGH is the most common explanation, white spots can sometimes indicate other conditions:

1. Tinea Versicolor

This is a fungal infection caused by yeast that naturally lives on your skin. When it overgrows, it can cause:

  • White, pink, or tan patches

  • Often on the chest, back, and shoulders
