CO2 laser resurfacing: still a good treatment.

Area of Science:

• Dermatology
• Aesthetic Medicine
• Laser Surgery

Background:

• Aging skin and facial rhytids present significant aesthetic concerns.
• Carbon dioxide (CO2) laser resurfacing is a well-established modality for skin rejuvenation.
• Understanding the physics, histology, and history of CO2 lasers is crucial for effective application.

Purpose of the Study:

• To recommend CO2 laser resurfacing as an excellent tool for treating aging skin, particularly moderate to severe facial rhytids.
• To discuss techniques for avoiding common disadvantages through proper patient selection and conservative settings.
• To evaluate the efficacy of CO2 laser resurfacing alone and in combination with other modalities.

Main Methods:

• Review of CO2 laser physics, histology, and historical application in dermatology.
• Application of CO2 laser resurfacing with controlled fluence, density, and pattern size.
• Combination treatments including trichloroacetic acid peels, phenol peels, and dermabrasion.

Main Results:

• CO2 laser resurfacing offers an excellent benefit-risk ratio when parameters are carefully controlled.
• Combination therapies with chemical peels and dermabrasion yield outstanding results.
• Simultaneous rhytidectomy and CO2 laser resurfacing can be performed safely and effectively.

Conclusions:

• CO2 laser resurfacing remains a highly effective treatment for aging skin and facial wrinkles.
• Proper patient selection and conservative treatment settings are key to maximizing benefits and minimizing risks.
• While newer technologies exist, CO2 laser offers a cost-effective solution with arguably superior results in many cases.
