Ultrasound-enhanced delivery of tranexamic acid and glutathione for facial melasma

Official title: Clinical Trial on the Efficacy and Safety of Ultrasound-Enhanced Delivery of Compound Tranexamic Acid Solution in the Treatment of Melasma

Run by The First Affiliated Hospital with Nanjing Medical University · NCT07202156 · Data updated 2026-11-12

This trial will test whether using ultrasound to help the skin absorb a 10% tranexamic acid and 2% glutathione solution reduces facial melasma in adults aged 20–55.

Is this trial a fit for you?

Likely a good fit

Adults aged 20–55 with clinically diagnosed facial melasma who can consent, comply with follow-up visits, and agree to photographic documentation are ideal candidates.

Probably not a fit

People who are pregnant or breastfeeding, allergic to tranexamic acid, have a history of thrombosis or certain ocular problems, or cannot stop estrogen-containing medications are unlikely to benefit or be eligible.

What this trial studies

This randomized split-face controlled trial compares a compound solution (10% tranexamic acid, 2% reduced glutathione) delivered with active ultrasound (5 W/cm² for 10 minutes) on one side of the face versus the same solution with ultrasound off (0 W/cm²) on the other side. Participants are adults 20–55 with clinically diagnosed facial melasma who will receive topical application, photographic documentation, and scheduled follow-up visits. The approach is based on preliminary basic and clinical data showing ultrasound-assisted delivery improves absorption of water-soluble agents and that the skin-barrier effects are temporary and reversible. Safety monitoring includes screening for allergy to tranexamic acid, thrombotic history, pregnancy/lactation, and ocular abnormalities.

Why it matters

Potential benefit: If successful, this could provide a noninvasive method to improve delivery of water-soluble agents and reduce pigmentation in facial melasma.

How similar studies have gone: Topical and oral tranexamic acid have prior clinical use for melasma and preliminary studies suggest ultrasound can improve transdermal uptake, but larger controlled split-face trials are limited.
