[Latest Melasma Treatment Survey] 70% Unaware of Laser Worsening Risks, Only 23.7% Understand Optimal 8-12 Week Tranexamic Acid Regimen

Key Survey Findings Melasma manifests as light brown, symmetrical patches on the cheekbones. Because standard spot-removal lasers carry a risk of exacerbating melasma, treatment based on oral tranexamic acid is recommended. Effectiveness is typically felt after 8 to 12 weeks of consistent intake, and combined use with laser toning may offer improved results.
