Skin contraction following erbium:YAG laser resurfacing
Summary
Erbium (Er):YAG laser resurfacing effectively tightens skin by causing measurable cutaneous contraction. This laser treatment offers a new method for skin tightening, showing significant results over 16 weeks.
Area of Science:
- Dermatology
- Laser Medicine
- Aesthetic Surgery
Background:
- Skin resurfacing methods like chemical peels, dermabrasion, and lasers induce dermal remodeling for skin tightening.
- The erbium (Er):YAG laser efficiently removes tissue with minimal thermal damage, making it a novel resurfacing tool.
Purpose of the Study:
- To document and quantify the cutaneous contraction induced by Er:YAG laser resurfacing on human skin.
Main Methods:
- Lentigos were used as skin markers on human forearm skin.
- Square areas were resurfaced with the Er:YAG laser, and distances between markers were measured pre-procedure and at multiple time points up to 16 weeks post-procedure.
Main Results:
- Two to three passes of the Er:YAG laser resulted in immediate 4% linear skin tightening.
- This tightening increased progressively, reaching 14% at 16 weeks post-treatment.
Conclusions:
- Er:YAG laser resurfacing demonstrably produces cutaneous contraction.
- This contraction phenomenon likely contributes to the observed clinical skin tightening effects of Er:YAG laser treatments.
