The only sign of melasma is dark patches of skin. It is not painful or itchy.
Not all brown patches on your skin are melasma. Talk to your doctor about changes in your skin.
Your doctor will ask about your symptoms and medical history. Your skin will be examined. A lamp, called a Wood’s lamp, may be used to look at your skin. A small sample of skin may be taken for a biopsy. The sample will be sent to a lab to confirm the diagnosis.
Melasma may go away on its own. If it does not go away, it may need to be treated. In general, treating melasma can be difficult. Talk with your doctor about the best treatment plan for you.
Factors that are causing the melasma may be removed. For example:
- Melasma associated with pregnancy may slowly fade after giving birth
- Melasma associated with birth control pills or hormone replacement therapy may fade after the medication is stopped
It can reappear and become darker if you become pregnant again or resume taking medication.

- Chemical peel
- Microdermabrasion—removing top layer of skin
- Laser therapy
Along with treatment, avoid using products that can irritate your skin. These include make-up, creams, and cleansers.
