Flexible, surface-lighting MicroLED skin patch for multiple human skincare.

Summary

This engineering–clinical study introduces a flexible surface-lighting microLED patch that delivers uniform, high-density irradiation while conforming to skin. Early clinical testing demonstrated pore tightening and skin rejuvenation, suggesting a non-invasive, home-use phototherapy platform with improved light delivery versus conventional LEDs.

Key Findings

• Developed a flexible, surface-lighting microLED (FSLED) patch with uniform emission and high mechanical flexibility via pick-and-place transfer.
• Designed for efficient, even light delivery by conformal contact with skin, enabling high-density irradiation over large areas.
• Clinical trials demonstrated improvements in pore tightening and skin rejuvenation.

Clinical Implications

May enable more effective, comfortable, and adherent at-home phototherapy for pore and rejuvenation indications, potentially reducing clinic visits and improving outcomes.

Limitations

• Sample size and trial design details (randomization, controls, duration) are not specified in the abstract
• Long-term safety, durability, and head-to-head comparisons with standard phototherapy devices are not reported

Future Directions

Conduct randomized controlled trials with standardized endpoints, dose–response optimization, and long-term safety monitoring; evaluate indications beyond rejuvenation (acne, dyschromia, wound healing).
