Overview
Melasma is a common skin condition that causes brown or greyish patches, usually on the cheeks, forehead, nose and upper lip. It is far more common in women and in people with brown skin, making it very common in India, and it is often triggered by sun exposure, pregnancy and hormonal changes. It is harmless but can be distressing. It tends to be stubborn and to return, but sun protection, and treatments guided by a skin doctor, can lighten it over time.
Symptoms
- Symmetrical brown or grey-brown patches on the face
- Patches on the cheeks, forehead, nose bridge and upper lip
- Darkening that worsens with sun exposure
- No itching, pain or scaling
- Onset or worsening in pregnancy or with hormonal changes
When to see a doctor
See a skin doctor for facial pigmentation that bothers you; strict daily sun protection is the foundation of any treatment.
Causes
Overactive pigment cells triggered by sunlight, pregnancy and hormones (including some contraceptive pills), and a genetic tendency.
