Ah! That sounds like a common skin concern. Small white spots on your arms or legs can be caused by several things. Experts often point to a few possibilities:
- Tinea Versicolor (Fungal Infection)
- This is caused by a yeast that naturally lives on the skin.
- It can create small, lighter patches, sometimes slightly itchy.
- More noticeable after sun exposure because the spots don’t tan.
- Pityriasis Alba
- Usually appears as pale, slightly scaly patches.
- Common in children and teens, often linked to dry skin or eczema.
- Not harmful and usually fades over time.
- Vitiligo
- A condition where the skin loses pigment.
- Spots are usually sharply defined and may spread over time.
- Sometimes associated with autoimmune conditions.
- Idiopathic Guttate Hypomelanosis (IGH)
- Small white dots, usually on arms and legs, often in older teens or adults.
- Considered harmless and linked to sun exposure and skin aging.
- Nutritional or Health Factors
- Rarely, low levels of certain nutrients like calcium or vitamin D can affect skin pigmentation.
What experts usually suggest:
- Keep your skin moisturized.
- Use sunscreen—sun exposure can make spots more noticeable.
- If spots grow, itch, or spread quickly, see a dermatologist.
- Avoid self-diagnosing with online pictures; a professional can confirm what it is.
