Q: Can hypopigmentation on the arms that has been present for about 10 years still leave one’s skin?
A: Hypopigmentation is the loss of color in the skin, and the contrast of the light spots is especially more noticeable after months in the summer sun, when the rest of your skin may be darker. If your pale spots have not changed in size over 10 years and are small, it is probably a common and benign condition that is actually a type of scarring, and which is not likely to disappear without treatment.
