MELASMA & SKIN PIGMENTATION


MELASMA & SKIN PIGMENTATION

Melasma is one of the commonest skin pigmentation disorders in the Asian population. The causes of melasma are complex and are related to genetic predisposition, hormonal effects, pregnancy, hypothyroidism, or photo-damage caused by sunlight exposure. Due to the high prevalence of melasma among Asian people, there are many studies and articles on melasma aetiology and treatments. Melasma typically occurs in middle-aged Asian women on areas exposed to sunlight, such as the cheeks, nose, forehead, upper lip, and the chin. Melasma usually starts as small, irregular brownish spots that gradually enlarge and merge to form brownish patches on the face. Because melasma usually occurs on the prominent locations in the face, the lesions are easily noticeable, especially in fair-skinned people.

Management of Melasma

Treatments of melasma may take weeks or even months before the desired results are achieved, especially for severe and chronic cases. There is no overnight fix. Generally, a combination of measures is required for the treatment to be effective:

1.    UV and Sunlight Protection. Protection from the sunlight and UV light (ultra-violet) is essential, especially in tropical countries like Malaysia because of the intense sunlight and chronic UV exposure. The daily use of good-quality sunscreen gel/cream with SPF 50 or above is crucial for adequate protection. The patients are also encouraged to use physical UV barriers such as a UV-proof umbrella, hat, and clothing when going outdoors. UV screen for car and home windows are helpful. Continuing sunlight and UV protection are essential to prevent the recurrence of melasma.

2.    Topical Agents. There are a variety of products that can lighten and bleach the skin pigmentation in melasma. These products are applied to the affected areas to speed up natural cell turnover and block melanin production, which causes skin pigmentation in melasma.

3.    Laser therapy: Q-Switched Nd-YAG Laser System (MedliteÒ). Q-switched Nd-YAG laser is the gold standard for the treatment of melasma. The laser delivers high-energy pulses in nano-seconds to selectively break down the melasma pigments without damaging the surrounding tissues. Treatment is performed every 1-2 weeks for a total of 6-8 sessions. Downtime is minimal, and the patient can go back to work immediately after treatment.

c.     Apply sunscreen at least twice a day, once in the morning and once in the evening. In the events the sunscreen wears off due to sweating, face-washing, or swimming, the patient needs to reapply the sunscreen to ensure continuing protection.

d.    Use physical sun protection such as an anti-UV umbrella and hat while going out under the sunlight.

 

e.    Continuing sun protection is crucial to maintain satisfactory results and prevent the recurrence of melasma.
