White Sun Spots
Another common cause is idiopathic guttate hypomelanosis, often called white sun spots.
These small, flat white spots usually develop on:
- Arms
- Legs
- Shoulders
- Face
They are associated with years of sun exposure and become more common with age. Fortunately, they are generally considered harmless.
Fungal Infections
Certain fungal infections can also cause lighter patches of skin.
The spots may:
- Appear on the chest, back, neck, or arms
- Become more noticeable after sun exposure
- Occasionally cause mild itching
Unlike milia, these spots may require antifungal treatment recommended by a healthcare professional.
Vitiligo and Other Pigment Conditions
Some white spots result from conditions that affect the skin’s pigment-producing cells.
Vitiligo, for example, occurs when the body’s immune system attacks the cells responsible for producing skin pigment. The condition often causes larger, clearly defined white patches that may gradually spread over time.
Can You Get Rid of White Spots?
Treatment depends entirely on the underlying cause.
Possible approaches include:
- Gentle cleansing and exfoliation for milia
- Prescription creams
- Antifungal medications
- Moisturizers
- Sun protection
- Dermatological procedures in some cases
Some types of white spots may disappear on their own, while others can persist for years without causing any health problems.
