The objective of this study is evaluating the clinical activity of the association (tretinoin + arbutin + triamcinolone) in the treatment of epidermal melasma.

Official title: Efficiency And Safety Of Association Arbutin, Triamcinolone And Tretinoin In The Treatment Of Facial Melasma, Taking As Reference The Product Triluma ® (Hidroquinone, Fluoncinolone And Tretinoin).

Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Active Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: evaluating the clinical activity of the association (tretinoin + arbutin + triamcinolone)in the treatment of epidermal melasma. (Time Frame: arbutin triamcinolone tretinoin)

Detailed description: The melasma is a common hipermelanosis, acquired, symmetrical, with irregular occurring in areas such as photo-exposed face, forehead and temples, can affect the eyelids and tion. The facial regions most affected are: zigomatic (82. 4%), parotid (64. 7%), front (64. 7%), mandible (35. 3%) and nasal (35. 3%).

The injuries of melasma is variable increase of epidermal melanin and inflammatory infiltrate of mild to moderate intensity. Treatment with compounds such as hydroquinone and derivatives, tretinoin, corticosteroids moderate or combination of them all have shown good results, diminishing the training, reducing the stability and promoting the destruction of melanocytes. The primary objective of this study is evaluating the clinical activity of the association (tretinoin + arbutin + triamcinolone) manufactured by Glenmark Laboratory, and as the comparator drug product Triluma ® (hydroquinone + fluocinolone + tretinoin), in the treatment of epidermal melasma through parameters of clinical course of the disease (improves) and its security.

Patients who are included in the study will be randomly and automatically receive one of the treatments (New association or Triluma ®), which should use for 12 weeks. The products should be applied in the regions affected once a day, during night.

Severity Scale (Melasma Area and Severity Index - MASI), which quantifies the melasma and

will be the main tool of control of clinical improvement.
