What is Melasma? How To Treat Melasma? Melasma is a form of hyperpigmentation that is very common among Asians. It is also known as the ‘mask of pregnancy’.
It appears as dark, often symmetrical , blotchy patches on the upper cheek, forehead, nose and lips. It can also appear on the neck, chest and even forearm.
Although melasma can affect both men and women, it is way more common in women. Onset can be as earlier as 20 year of age, and it does continue to affect people 60s and beyond.
What causes melasma?
In melasma, there is increased activity of melanocytes, which are cells in our body that produces pigment.
The exact cause is unknown and is though to be multifactorial in nature. Listed below are some of the known predisposing factors for developing melasma;
- Family history of melasma
- Asian Skin Type
- Sun exposure
- Child bearing age
- Increased exposure to female hormones such as use of oral contraceptive pills or hormone replacement pills
How To Treat Melasma?
Melasma is a common pigmentary problem affecting Asian skin. It causes brown or gray patches to appear on the skin, primarily on the face. Unfortunately, it is also one of the hardest pigmentary disorders to treat. Having melasma is akin to having diabetes or high blood pressure. It is a chronic condition and requires long term maintenance. Melasma can be improved but it cannot be cured.
How should melasma be treated?
1. Firstly, get the correct diagnosis.
Other pigmentary disorders like freckles, solar lentingies, post inflammatory hyperpigmentation may be mistaken for melasma. An experience physician would be able to diagnose melasma from physical examination alone.
2. Secondly, reduce all risk factors as much as possible!
Sunscreen is of utmost importance! A broad spectrum suncreen, one that blocks both UVA and UVB should be used. SPF should be at least 50 and frequent reapplication, as often as every 2-3 hours, is a must.

Hormonal factors also play a part in melasma formation. If melasma is brought about by use of oral contraceptive pills, those pills have to be stopped and alternative mode of contraception sought.
3. Thirdly, use proven treatments like topicals containing hydroxyquinone, retinoids and mild corticosteroids.
Other agents that can be added include Kojic acid, Azelaic acid, Vitamin C and Arbutin.
Can lasers be used for melasma?
Lasers are considered second line for treatment of melasma. Situations whereby lasers can be used include:
- Concomittant pigmentary disorders amenable to laser treatment
2. Recalcitrant melasma, where the melasma is responding poorly to treatments mentioned above after 6-8 weeks of therapy.
Treatments for melasma are numerous and varied. Chemical peels, topical lightening agents, lasers, intense pulse light and oral medications have all been used to treat melasma. Best results are obtained with combination therapy. Mono-therapy more often than not results in sub-optimal results and patient dissatisfaction. In general, at least 2 modalities need to be used, depending on severity of the melasma. For mild cases, lightening cream and chemical peels are used. For more severe cases ,low-energy lasers or intense pulse light , and oral medications are used. Melasma is a complex condition and there is essentially no cure for it. However, it is still possible to improve the condition or improve the appearance, if one remains compliant to his/her physician instructions and reduce all risk factors as far as possible. Melasma can be very distressing. Although it cannot be cured, it certainly can be improved and combination therapy is key. Not all treatment modalities are suitable for everyone.
