A total of 73 patients were included in this study with age ranging from 22 years to 47 years. All of them had resistant melasma and had not taken any treatment for the last six months. Results: Out of 73 patient 10 (13.7%) patients had poor response, 48 (65.8%) patients had fair response, 14 (19.1%) patients had good responses and only 1 (1.4%) had excellent response. No significant side effects were observed. Out of 73 patients, 63 patients were satisfied with the treatment. Only 2 patients complained of redness over the affected area which subsided within a week without any intervention, no other side effects were noted. Conclusion: Intralesonal tranexamic acid is safe, effective and an affordable option in resistant melasma.
