Melasma

Learn more about Melasma

Melasma is caused by an increase in melanin production in the skin. Melanin is the pigment that gives your skin its colour. The exact cause of increase melanin production is COMPLEX & generally UNKNOWN, but many different factors may play a role. These include genetics, sun exposure and hormonal changes (e.g. using the oral contraceptive pill, pregnancy). Melasma can be caused or worsened by not only the sun's rays, but also heat and visible light.

Melasma typically appears as light to dark Brown or greyish spots on the face with irregular border, it is usually symmetrical, appearing on both sides of the face.

Melasma is usually diagnosed based on clinical appearance and examination with a Wood lamp or dermatoscope. Rarely, a skin biopsy may be needed to rule out other similar inflammatory conditions.

Melasma is challenging to treat & usually recurs back. A combination of treatments is generally required and

ongoing light-protection& maintenance therapy to reduce risk of its recurrence is usually required.

General Measures:

• Year-round, life-long SUN PROTECTION is essential with broad-brimmed hat, broad-spectrum very high protection factor (SPF50+ or more) Sunscreens, applied every 2-3 hours, 20 minutes prior to sun exposure. Sunscreen with Physical blocker and Tinted base (containing Iron Oxides) is recommended especially in people with skin of colour.

• If Hormonal factors are implicated, the use of the oral contraceptive pill or intrauterine devices should be discontinued. Other forms of contraception have a lower risk of worsening melasma.

• Avoid or reduce risk of heat exposure.

• Cosmetic Camouflage: Use makeup to cover affected areas.

Medical Therapy

• Prescription compounded skin lightening creams

• Chemical Peels: Such as Alpha-hydroxy acids (AHA) peels.  

Laser Therapy: Certain lasers can help lighten the discolouration, but they may have side effects and require multiple sessions.
