    Journal: J Drugs Dermatol; 2009 Mar; 8(3):248-52. PubMed ID: 19271372.
    Abstract:
    BACKGROUND: Traditional full-face resurfacing has been limited to erbium-doped yttrium aluminium garnet (Er:YAG) and carbon dioxide (CO2) lasers. These devices offer wavelength-specific advantages and disadvantages. METHODS: Nine patients were enrolled in a pilot study of a resurfacing system using a 2790-nm erbium:yttrium-scandium-gallium-garnet (Er:YSGG) laser system. Two treatments were carried out 1 month apart over the entire face. Test spots were performed prior to the full-face sessions to determine the optimal fluence for 1-pass laser resurfacing. Biopsies were performed at the time of treatment and at the final follow-up visit one month after the second treatment. Clinical endpoints included changes in pigment dyschromias, wrinkles, and skin tone. All outcomes were graded by blinded observers. RESULTS: Eight patients completed the 2 treatments. Biopsies showed thermal damage extending as deep as 80 microm below the stratum corneum. Reepithelialization was complete within 4 days. No scarring, post inflammatory hyperpigmentation (PIH), or infections were observed. CONCLUSION: A 2790-nm laser can be used for skin rejuvenation with a 4 day recovery window.
