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)
Ironically, sun damage can cause both dark spots and white spots. Some people develop white spots where sun exposure has destroyed pigment cells over time—essentially, tiny areas of sun damage.
