ClinConnect Summary

This clinical trial is studying how a special liquid dressing containing exosomes can help patients recover after undergoing a specific type of laser treatment called Nd:YAG laser 532. The goal is to see if this dressing can improve healing and skin regeneration in patients with certain skin conditions, like seborrheic keratosis or freckles.

To participate in this study, you should be between 65 and 74 years old and be able to follow the treatment rules for at least 8 weeks. It's important that you don’t have a history of keloids (thick, raised scars), are not pregnant or breastfeeding, and have not used any cosmetics with growth factors in the past six months. If you qualify and choose to join, you'll apply the dressing to one side of your face after the laser treatment and follow up with the study team to track your recovery. This trial is currently recruiting participants of all genders, and it offers a chance to contribute to understanding new ways to enhance skin healing after laser procedures.
