Sometimes, nutritional deficiencies, allergies, or skin irritation from harsh products can contribute to changes in skin color. Stress and certain autoimmune conditions may also play a role in some cases.
Treatment depends on the exact cause. Doctors may recommend antifungal creams, moisturizers, medicated ointments, or light-based therapies. In many situations, protecting the skin from excessive sun exposure and maintaining a healthy skincare routine can help improve the appearance of the spots.
Although many white spots are harmless, it is important to pay attention if they spread quickly, become itchy or painful, or change in appearance. Consulting a dermatologist can help determine the exact cause and the most effective treatment.
