To evaluate the efficacy and safety of picosecond 532 nm laser (PS 532) and 755 nm Q-switched Alexandrite laser (QSAL) for treatment of freckles in a split-face manner. Eighteen patients with freckles were enrolled in the study. The right and left sides of their faces were randomly assigned to either a QSAL-treated group or PS 532-treated group. The degree of pain, satisfaction with the results, and adverse events associated with the laser treatment were evaluated using a questionnaire. All of the patients were followed up at 4 and 12 weeks after one treatment session. Among the 18 patients, PS 532 was found to be associated with less pain (3.56 ± 2.431) than QSAL (3.94 ± 1.893), but the difference was not statistically significant. The curative effect and satisfaction associated with 755 nm Q-switched Alexandrite laser was greater than that of picosecond 532 nm laser (P < .001). Both picosecond 532 nm laser and QSAL are effective in the treatment of freckles, and QSAL has a greater rate of satisfaction and curative effect.","PeriodicalId":54852,"journal":{"name":"Journal of Cosmetic and Laser Therapy","volume":"22 1","pages":"22 - 27"},"PeriodicalIF":1.2,"publicationDate":"2022-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89168359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control (non-varicose) and varicose vein specimens were subjected to chemical, thermal and morphological analyses. Varicose vein fragments were irradiated with 1.56-μm and 0.97-μm lasers in conditions closely similar to those of the clinical EVLA procedure. The laser treated specimens were subjected to thermal and histological analyses. A noticeable difference in chemical composition and structure was detected between the control and varicose veins. Glycosaminoglycan content increased significantly in varicose vein (P = .02), elastin content decreased insignificantly (P = .26) while collagen content showed a slight, but not significant, increase (P = .14). Varicose vein demonstrated regional variability in wall thickness, some decrease in the amount of smooth muscle cells, thinning and loosening of collagen fibers and fibrosis. The critical laser radiation power was demonstrated simultaneously to cause complete denaturation of collagen (as indicated by the DSC data) and coagulation necrosis of all the three venous wall layers, total homogenization of the tissue and obliteration of vasa vasorum (as indicated by the histological analysis data). Lower laser radiation powers fail to produce these effects. Critical laser power provides the desired result of the thermal effect on the vein ex vivo, namely, tissue necrosis and vasa vasorum destruction. The complete degradation of the collagen recorded by DSC could be a marker of the irreversible destruction of the vein wall in modeling of endoluminal thermal treatment.","PeriodicalId":54852,"journal":{"name":"Journal of Cosmetic and Laser Therapy","volume":"199 1","pages":"163 - 169"},"PeriodicalIF":1.2,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74977589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have explored approaches designed to improve treatment efficacy. This integrative literature review summarizes the results of clinical and animal studies published between 2004 and 2021. Pulsed dye laser has been administered in combination with photoelectric devices (the neodymium: yttrium-aluminum-garnet lasers, dual-wavelength 1064-/595-nm laser irradiation, fiberoptic Nd-YAG laser, photodynamic therapy, and radio frequency), and drugs (rapamycin, imiquimod, timolol, axitinib, endothelin receptor antagonist, artificial red blood cells and oxymetazoline). The initial results suggest that combination therapy is a direction worth exploring in the future.

Moiré is a type of interference pattern corresponding to the shape of the face. We aimed to objectively evaluate the effect of RF on facial skin laxity using moiré. Ten subjects participated and were treated with a monopolar RF on the face. Clinical photographs and moiré images were obtained at the baseline and after treatment. The periorbital angle from the upper third of the face, zygomatic length ratio (L1/L2), angle from the middle third, perioral perpendicular length, and angle from the lower third were analyzed. After one session of RF treatment, the mean zygomatic length ratio (L1/L2) from the middle third of the face significantly increased in the 4th week (by 49.68%, P = .047). The L1/L2 ratio increased to nearly one, which were not significant after 8 weeks. The mean perioral perpendicular length decreased to 282.25 ± 84.069 pixels (px) after 4 weeks, and to 281.38 ± 76.03 px after 24 weeks; these differences were statistically significant.

Measurements included cosmetic results, complications and patients’ satisfaction. Eighty lesions involved the gray line and 24 lesions were in the lacrimal region.

However, transcutaneous drug delivery of cosmeceuticals initially meant for topical application have also been shown to have unintended side effects. The objective of our study was to report safety data from our single academic center experience consisting of patients treated with topical application of a vitamin C-containing cosmeceutical immediately following fractional ablative CO2 laser treatment with a focus on reportable side effects. Methods: A retrospective chart review of all patients at the University of Minnesota M Health Cosmetic Center who had fractional ablative CO2 (10,600 nm) laser procedure for any diagnosis followed by immediate one-time application of a combination serum containing 15% Vitamin C, 1% Vitamin E, and 0.5% Ferulic acid (C E Ferulic®, SkinCeuticals Inc., New York, NY) from Jan 1, 2015 to Dec 31, 2018 was performed. Pediatric and research opt-out patients were excluded. The medical records of these patients were manually reviewed for the following: age, sex, diagnosis, location, after-care instructions, antiviral and/or antibacterial prophylaxis use, and documentation of post-procedure side effects. Results: Thirty-three patients, encompassing a total of 45 treatment encounters, met inclusion criteria. There were ten cases of expected side effects: erythema (6), erythema with tenderness (1), erythema with mild bumpiness (1), skin peeling with pattern marking (1), and pain with slight bleeding (1). These were attributed to the normal post-procedure course and resolved without complications. There were no reported side effects related to the topical application of Vitamin C, Vitamin E, and Ferulic acid serum. Conclusions: The topical application of a Vitamin C, Vitamin E, and Ferulic acid serum immediately following fractional ablative CO2 laser therapy did not result in associated complications. However, these results may not be generalizable to longer application courses beyond the immediate post-procedure time period, nor to other cosmeceutical formulations.

Case presentation of a patient underwent picosecond laser cosmetic treatment, complicated with severe corneal burn injury. We evaluate patient’s visual acuity, corneal edema condition under slit lamp and corneal OCT (Optical coherence tomography), corneal shape with topography, and intraocular pressure. Picosecond laser emits optical pulses with duration between one to tens of picoseconds. The original purpose was to remove tattoos, but has now extended to a wide range of skin diseases and even cosmetic use. When applying cutaneous laser therapy, several ocular adverse events have been reported, mostly due to no appropriate ocular protection during treatment. We report a case of corneal burn injury after receiving picolaser therapy for a pigmented lesion over the upper lid. Severe cornea edema and vision impairment improved gradually after appropriate treatment. Even picosecond laser produce less thermal burns then other lasers, it is essential to use ocular protection during the entire treatment.
