While IGH is the most common explanation, white spots can sometimes indicate other conditions:
1. Tinea Versicolor
This is a fungal infection caused by yeast that naturally lives on your skin. When it overgrows, it can cause:
-
White, pink, or tan patches
-
Often on the chest, back, and shoulders
-
May be slightly scaly
-
More noticeable in summer (the yeast prevents tanning)
Treatment: Over-the-counter antifungal creams or shampoos often clear it up.
2. Vitiligo
An autoimmune condition where the immune system attacks pigment-producing cells (melanocytes):
-
Larger, irregular patches of complete pigment loss
-
Can appear anywhere on the body
-
Often symmetrical (appears on both sides)
-
May run in families
Treatment: Options include topical steroids, light therapy, and camouflage makeup. A dermatologist can help.
3. Post-Inflammatory Hypopigmentation
After an injury, rash, or inflammation, some people lose pigment in the affected area:
-
Follows a pattern of previous skin trauma
-
May gradually repigment over time
-
Common after eczema flares or minor injuries
4. Sunspots (Not the Kind You Think)
