The Bottom Line
Those small white spots on your arms or legs are most likely idiopathic guttate hypomelanosis—a harmless, common condition linked to sun exposure and aging. They’re not dangerous, not contagious, and not a sign of anything wrong with your health.
If they bother you cosmetically, talk to a dermatologist about options. If they don’t, simply consider them part of your skin’s unique story—evidence of all the sunny days you’ve enjoyed over a lifetime.
Either way, you can stop worrying. Your spots are almost certainly nothing to worry about.
