Study Overview
Brief Summary
The aim of the study:
1.To compare the efficacy and safety of fractional CO2 laser in combination with vitamin c and tranexamic acid in the treatment of melasma.
2 .To assess the value of dermoscope in measuring of the response to treatment in melasma patients compared to clinical scoring.
Detailed Description
Melasma is a chronic dermatologic condition defined by hyperpigmented macules and patches that appear in areas of sun exposure .
Traditionally, the mainstays of treatment for melasma have been topical bleaching agents and strict photoprotection.
Additional adjuvant treatment modalities include chemical peels, dermabrasion, and laser treatments, all of which have demonstrated limited efficacy. There has been an interest in studying the effects of vitamin c and tranexamic acid in melasma.
The development of fractional resurfacing has led to improvements to melasma treatment with decreased incidence of post-inflammatory hyperpigmentation; these improvements are due to the enhanced healing times and decreased inflammation as a result of the formation of microscopic columns of tissue destruction.
These microscopic columns of damaged tissue are surrounded by areas of normal tissue, allowing for shorter migratory paths for the healing keratinocytes.

Outcomes
Primary Outcomes
Efficacy and safety of fractional CO2 laser in treatment of melasma.
Time Frame: 1year
1.: For each patient, Right side of the face : Fractional ablative CO2 laser will be followed by immediate topical application of vitamin c 3% . Left side of the face: Fractional ablative CO2 laser will be followed by immediate topical application of tranexamic acid. * Fractional ablative CO2 laser sessions will be performed using the following parameters: power 8-10 W (according to the skin type), spacing 1000 μm (5.3% density), dwell time 400 μs, and stack . * During the session, protective goggles will be used both by the patient and by the physician. acid in the treatment of melasma. 2 .To assess the value of dermoscope in measuring of the response to treatment in melasma patients compared to clinical scoring.
