Don’t ignore these small white spots on your arms or legs… here’s why!”

Seasonality: It becomes very apparent during the summertime. This is not due to exposure to the sun, but rather because the white spots do not tan, and thus, the contrast between the two becomes more pronounced.

DermNet NZ classifies this as a self-limiting condition, meaning it eventually goes away on its own as the child reaches adulthood.

Treatment and Care

The goal here is hydration. In this case, the treatment would involve the rehydration of the skin. It is recommended that you apply a thick moisturizing lotion without any smell two times a day. In case the patches appear red or irritated, then a hydrocortisone cream available over the counter could be applied for a couple of days.

4. Vitiligo: When the Immune System Intervenes
Perhaps the most well-known cause of white patches is Vitiligo. This is an autoimmune condition where the body’s immune system mistakenly attacks and destroys its own melanocytes.

Vitiligo is distinct because the loss of pigment is usually complete—the patches are “milky white” rather than just “pale.” It affects approximately 1% of the world’s population and can start at any age.

Appearance: Clearly outlined chalk-white patches that tend to be symmetrical, with matching locations such as the two elbows, both knees, or both sides of the face.
