BACKGROUND: Melasma is a common hyperpigmentation disorder, which causes brownish discoloration of the face. Despite unclear mechanisms, thyroid hormones were thought to play a role in melasma.AIM: This study aims to determine and compare the clinical improvement of melasma in hyperthyroid patients receiving anti-thyroid drugs.METHODS: An interventional study with a quasi-experimental design (pre-post-intervention study) was conducted at the Internal Medicine Outpatient Clinic and Dermatology and Venereology Outpatient Clinic, Cipto Mangunkusumo Hospital, Jakarta, Indonesia, from July 2019 to March 2020. A comparative analysis was done to compare the modified melasma area and severity index (mMASI) in hyperthyroid patients before and after 12 weeks of anti-thyroid drugs. All subjects did not receive any additional topical therapies for their melasma. The clinical features were evaluated objectively at baseline and 12th-week visit, by mMASI score on different areas of the face (forehead, left-right malar, and chin) and Wood’s lamp examination.RESULTS: All areas showed a decline in mMASI score components (e.g., involvement areas and darkness degree) after 12 weeks of treatment. However, only the malar area showed a significant decline (p < 0.05). Wood’s lamp examination at baseline revealed dermal type melasma on 17 subjects, mixed type on six subjects, and epidermal type on one subject. All types remained unchanged after 12 weeks of treatment.CONCLUSIONS: Our study demonstrated that mMASI score in malar area improved significantly, this might be because malar area included this study were comprised of epidermal, dermal, and mixed type. On the other hand, based on Wood’s lamp examination, all types of melasma remained unchanged after 12 weeks of treatment.
