OBJECTIVE: To investigate the different treatment modalities employed for melasma by practicing dermatologists in the Philippines. BACKGROUND: Melasma is a prevalent skin condition among Filipinos due to our skin type and climate. To date, no local studies have been done investigating the different treatment regimens practiced/ employed by Filipino dermatologists in treating melasma. METHODS: This is a descriptive study investigating the different treatment strategies used by Filipino dermatologists using a questionnaire.The questionnaires were given to practicing Filipino dermatologists personally during conferences and conventions held in 2005 as well as to the different Philippine Dermatological Society accredited training institutions and private clinics of the doctors. The total sample size was 117. RESULTS: Melasma is frequently seen among Fitzpatrick skin type IV (50%),females, 41-50 year-old age group (50%) and commonly on the cheeks (98%). Grade 2 severity melasma was often seen by 75% of the respondents. The top 3 topical depigmenting agents of choice are tretinoin, hydroquinone and combination therapy. Microdermabrasion was preferred by 43.5% of the respondents over laser. Once combination treatment regimens fail, laser treatment more than doubled to 28.7%. Vitamin C (37.7%) and glutathione (31.6%) are the most common oral maintenance therapy given by the respondents. Half of all the respondents advise continuous maintenance therapy while a third of them advise maintenance for a year. The most common side effect of melasma treatment is erythema according to 51% of the respondents followed largely by hyperpigmentation (23%) and scaling (22%). More than half of the dermatologists surveyed stop the treatment regimen when side effects are observed. Almost all respondents advise patients to use sunblock daily and majority of respondents prescribe both UVB and UVA sunblocks.
