Why Do White Spots Become More Noticeable in Summer?
Sun exposure does not necessarily cause the spots themselves, but it can make them much easier to see.
Healthy skin becomes darker when it tans, while areas affected by certain pigmentation disorders may not tan in the same way. This creates a visible contrast between the surrounding tanned skin and the lighter patches.
Pityriasis versicolor is more common or noticeable during hot and humid periods because heat, humidity and sweating can encourage the excessive growth of Malassezia, a yeast that normally lives on the skin.
