Chloasma (Melasma, Pregnancy Mask)

What is melasma?

• Chloasma consists of brown spots/patches on both sides of the face, especially on the cheeks, upper lips, nose and chin. The distribution is usually symmetrical. Chloasma is mainly seen in women of child-bearing age.
• The colour in Chloasma darkens during sunlight exposure. Chloasma tends to occur during pregnancy and with the use of oral contraceptives.
• Chloasma may fade after childbirth or discontinuation of oral contraceptives, but it tends to persist.

What is the treatment of melasma?

• One or more of the following may be tried:

1. Remove the underlying cause e.g. oral contraceptives.
2. Use sunscreen regularly and avoid sun exposure as far as possible. This will minimise further darkening of the lesions.

• Bleaching agents such as hydroquinone can be used to lighten the colour. The treatment usually takes several months.

• Cosmetic camouflage can be used to hide the colour.
