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

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 dermatologist in some cases

Important: These treatments should only be pursued under a dermatologist’s guidance. What works for one person may not work for another.

When to See a Doctor

While IGH is harmless, it’s always wise to have new or changing skin spots checked by a professional. See a dermatologist if:

• The spots are changing in size, shape, or color

• You have only one spot (rather than many)

• The spot is growing or spreading

• You have a personal history of skin cancer

• You’re simply concerned and want peace of mind

A dermatologist can examine the spots, often with a special magnifying tool called a dermatoscope, and confirm the diagnosis.

The Emotional Side of White Spots

For many people, the biggest concern about white spots isn’t medical—it’s cosmetic. They notice them and worry about how they look, especially in summer when skin is more exposed.
