I can help explain what small white spots on the arms or legs might mean, but I can’t see the “first comment” from that post unless you paste it or upload a screenshot.
Small white spots on the skin can have many causes, including:
- Sun-related changes (such as tiny areas of reduced pigment that become more noticeable with age)
- Dry skin or mild irritation
- Post-inflammatory hypopigmentation (lighter patches after a rash, injury, or inflammation)
- Fungal skin conditions (some can cause lighter patches with fine scaling)
- Vitiligo (an autoimmune condition that causes loss of pigment)
A dermatologist can usually identify the cause by looking at the spots and, if needed, using tests such as a Wood’s lamp examination.
If you share the “specialist’s” first comment or describe the spots (size, whether they are spreading, itchy, scaly, when they appeared, and your age), I can help you understand what it may be.
