Have You Noticed Small White Spots on Your Arms or Legs? Here’s What They Are
-
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)
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.

Can You Prevent or Treat IGH?
Since IGH is linked to sun exposure and aging, the best prevention is sun protection:
-
Use broad-spectrum sunscreen daily on exposed skin
-
Wear protective clothing when outdoors for long periods
-
Avoid tanning beds entirely
As for treatment: There’s no guaranteed way to make existing IGH spots disappear, but some people have success with:
-
Topical retinoids – May help stimulate pigment production
-
Cryotherapy – Freezing can sometimes trigger repigmentation (results vary)
-
Microneedling – Some evidence suggests it may help
-
Topical steroids – Prescribed by a de
