The appearance of small white spots on the skin, especially in sun-exposed areas, may indicate cumulative damage from UV radiation. The phenomenon, known as idiopathic guttate hypomelanosis (IGH), is caused by prolonged sun exposure that damages pigment cells. The spots themselves are benign and not dangerous, but they serve as a warning sign and increase the overall risk of skin cancer. Dermatologists recommend a full skin examination in case of spots appearing, and prevention using SPF 50+ sunscreen, protective clothing, and avoiding exposure during peak hours.
