Another possible cause is tinea versicolor, a superficial fungal infection caused by an overgrowth of naturally occurring skin yeast. Unlike IGH, these patches may appear on the chest, shoulders, back, or upper arms and can be slightly scaly or itchy. The color may be lighter or darker than the surrounding skin depending on a person's complexion. Antifungal creams or shampoos often clear the condition within a few weeks, although normal skin color may take longer to return.
Could Vitamin Deficiencies Be Responsible?
Some people wonder whether white spots indicate a vitamin deficiency. While vitamin B12, copper, or zinc deficiencies can contribute to pigment changes in rare cases, they are not the most common reason for tiny white spots on the skin. A balanced diet rich in fruits, vegetables, lean protein, whole grains, and healthy fats usually provides the nutrients necessary to maintain healthy skin.
If pigmentation changes occur alongside fatigue, numbness, weight loss, or other unexplained symptoms, a healthcare provider may recommend blood tests to identify nutritional deficiencies or other medical conditions.
