First Assessment of a Carbon Monoxide Laser and a Thulium Fiber Laser for Fractional Ablation of Skin.

Lasers Surg Med 2020 10 14;52(8):788-798. Epub 2020 Jan 14.

Institute of Biomedical Optics, University of Luebeck, Luebeck, 23562, Germany.

Background And Objectives: A recent generation of 5,500 nm wavelength carbon monoxide (CO) lasers could serve as a novel tool for applications in medicine and surgery. At this wavelength, the optical penetration depth is about three times higher than that of the 10,600 nm wavelength carbon dioxide (CO ) laser. As the amount of ablation and coagulation is strongly influenced by the wavelength, we anticipated that CO lasers would provide extended coagulation zones, which could be beneficial for several medical applications, such as tissue tightening effects after laser skin resurfacing.

Successful Treatment of Porokeratosis With Ablative Fractional Carbon Dioxide Laser and Vitamin C, E, and Ferulic Acid Serum

J Drugs Dermatol 2019 Nov;18(11):174-1176

Porokeratosis is a rare disorder of epidermal keratinization that encompasses several clinical forms, characterized by erythematous, annular plaques with an atrophic center and hyperkeratotic ridge-like border. The histopathological hallmark of porokeratosis is the cornoid lamella, a thin column of parakeratotic corneocytes embedded within the stratum corneum. There is no standard treatment regimen for porokeratosis. Read More

Histologic effects of resurfacing lasers.

Facial Plast Surg 2014 Feb 31;30(1):40-8. Epub 2014 Jan 31.

Department of Dermatology and Cutaneous Surgery, University of Miami, Miami, Florida.

By utilizing resurfacing lasers, physicians can significantly improve the appearance of sun-damaged skin, scars, and more. The carbon dioxide and erbium:yttrium-aluminum-garnet lasers were the first ablative resurfacing lasers to offer impressive results although these earlier treatments were associated with significant downtime. Later, nonablative resurfacing lasers such as the neodymium:yttrium-aluminum-garnet laser proved effective, after a series of treatments with less downtime, but with more modest results. Read More

Fractionation: past, present, future.

Semin Cutan Med Surg 2012 Jun;31(2):105-9

SkinCare Physicians, Chestnut Hill, MA 02467, USA.

The development of fractional photothermolysis is a milestone in the history of laser technology and cutaneous resurfacing. Based on the concept that skin is treated in a fractional manner, where narrow cylinders of tissue are thermally heated and normal adjacent skin is left unaffected, the fractional devices have shown effectiveness in treating a variety of conditions. Since its development, we are becoming more adept at using optimal parameters to induce near carbon dioxide laser benefits with a much more comfortable postoperative period and fewer complications.
