MATERIALS AND METHODS Some 242 solar-damaged anatomical sites on 61 human subjects were treated with three laser treatments at two study centers. The treatment involved applying a carbon suspension to the skin surface and irradiating the exogenous chromophore with a Q-switched Nd:YAG laser. Cosmetic skin-resurfacing was accomplished using a wavelength of 1064 nm, a fluence of 2.5 J/cm2, a pulse duration of 6-20 ns, a pulse repetition rate of 1-10 Hz and a fixed beam size of 7 mm. The treatment sites were evaluated at baseline, 4, 8, 14, 20 and 32 weeks for skin texture, skin elasticity and rhytid reduction. All sites were treated at baseline, 4 and 8 weeks. Skin replicas taken prior to treatment and at the conclusion of the study were analyzed for wrinkle and cosmetic improvement using the Magiscan digital image process system. Adverse events were recorded throughout the study. RESULTS At 8 months the investigators reported improvement in both skin texture and skin elasticity, as well as rhytid reduction compared to baseline. In self-assessments, subjects also reported noticeable skin texture and cosmetic improvement, but assessed wrinkle reduction less favorably than seen by the investigators. The majority of adverse events were limited to mild, brief erythema. CONCLUSIONS Topical carbon suspension assisted Q-switched Nd:YAG laser treatment offers a safe cosmetic method of resurfacing solar-damaged skin. The effect, as reported by investigators and subjects in this study, and confirmed by skin replica analyses, included improvement in skin texture, elasticity and rhytid appearance.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 1 1","pages":"23-7"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950517057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59799169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Post-treatment erythema is the most common side effect of this method of skin resurfacing. Sublethal thermal damage to the dermis has been proposed as an etiology for post laser erythema. Recent developments in laser resurfacing technology have aimed at minimizing thermal damage to the dermis. OBJECTIVE To determine depth of skin ablation, extent of thermal injury, and ideal laser parameters for the FeatherTouch laser system. To assess the safety and efficacy of laser resurfacing at high energy fluences with a single pass. DESIGN Laser resurfacing was performed in the preauricular skin of five patients undergoing rhytidectomy. A total of 60 sites were tested with fluences of 7 to 17 Joules/cm2. Histologic evaluation of excised skin showed maximal thermal injury to be restricted to 60 microns in the papillary dermis. The reticular dermis showed no evidence of injury. Based on these findings, laser resurfacing at 17 J/cm2 (70 watts) was performed on 30 patients (in the periorbital area, a maximum of 9 J/cm2 or 36 watts was used). Follow up ranged between 12 and 18 months. RESULTS Based on histologic comparison of average and high fluence laser resurfacing, high fluence laser resurfacing did not cause added thermal damage to the reticular dermis. In the clinical group, no major complications such as scarring, scleral show, infection or ectropion were encountered. Transient hyperpigmentation was noted in three patients. Overall patient satisfaction was good to excellent. Post-treatment erythema lasted an average of 4 weeks. CONCLUSION We conclude that CO2 laser resurfacing of the face (excluding the periorbital region) can be performed safely and effectively, with the FeatherTouch laser, at 17 J/cm2 with one pass. In our group of patients, laser resurfacing with a single pass at 17 J/cm2 caused less post-operative erythema than two or more passes at 9 J/cm2.","PeriodicalId":81650,"journal":{"name":"Journal of cutaneous laser therapy","volume":"1 1 1","pages":"37-40"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14628839950517075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59800023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
