Ultrapulsed CO2 Resurfacing of Photodamaged Facial Skin in Vegan and Omnivore Patients: A Multicentric Study
No full textBackground and Objectives: Skin photoaging is related to extrinsic environmental exposures, mainly represented by ultraviolet radiation. One of the treatment options is laser resurfacing. As nutritional status is involved in cutaneous photodamage, we evaluated whether dietary patterns can also influence the response to facial resurfacing. Our prospective multicentric study involves three dermatologic centers specialized in laser therapy in northern Italy. The study aims to compare the outcome of a CO2 ablative laser therapy between omnivore and vegan patients. Study Design/Materials and Methods: Fifty-three omnivore and fifty-three vegan women undergoing ultrapulsed CO2 resurfacing for photodamaged facial skin were enrolled in this study. Clinical improvement was evaluated 3 and 6 months after the treatment using the modified Dover score. Results: After laser treatment, vegans showed slower complete re-epithelialization (P < 0.001*) and disappearance of the erythema (P < 0.001*). After 3 and 6 months, vegans showed worse outcomes in terms of fine lines (P < 0.001* and P < 0.001*, respectively) and tactile roughness (P = 0.003* and P = 0.002*, respectively) compared with omnivores, while they did not differ in mottled pigmentation. Conclusions: The present study suggests that diet influences the clinical outcome of fractioned CO2 laser treatment. Lasers Surg. Med. © 2021 Wiley Periodicals LLC
Fractional 1064 nm picosecond laser and skin photoaging: in vivo evaluation of treatment effects with reflectance confocal microscopy
No full textFew studies showed the role of picosecond laser (PLS) in the treatment of skin photoaging signs. However, no studies have explored the microscopic effects of PSL in photoaging. The aim of this study is to preliminarily identify clinical variations induced by a 1,064 nm Nd:YAG PSL on the décolleté area, then to apply the treatment protocol to treat facial photoaging and estimate the clinical and microscopic outcomes. A total of 10 consecutive patients with cutaneous photoaging were enrolled. Patients were treated 3 times at monthly intervals with the fractionated 1,064 nm Nd:YAG PSL. In a preliminary phase, PSL treatment was performed on the décolleté to establish its efficacy and safety. Then, the same treatment protocol was applied to all the face and clinical and reflectance confocal microscopy (RCM) were analyzed, comparing baseline (T0) pictures and 4 months after the treatment (T1) ones. On the face, a reduction of dyschromia and wrinkles was observed at T1. Furthermore, the underlying RCM variations were revealed at different skin levels. Our results show the clinical and microscopic effectiveness and safety of the 1,064-nm Nd:YAG PSL in the treatment of skin photoaging signs
Picosecond Laser treatment of Striae Distensae: In vivo Evaluation of Results by 3D Analysis, Reflectance Confocal Microscopy, and Patient′s Satisfaction
No full textBackground and Objectives: The efficacy of picosecond laser (PSL) in the treatment of striae distensae (SD) has been recently reported; otherwise, the base for this improvement has not been clarified yet. The aim of this study is to treat long-lasting SD with PLS and to describe their in vivo morphological variations after treatment using three-dimensional (3D) imaging and reflectance confocal microscopy (RCM). Study Design/Materials and Methods: A total of 27 patients asking for treatment for SD were treated with four monthly sessions of PLS. Clinical improvement was estimated through a blinded evaluation performed by two independent dermatologists, Global Assessment Improvement Scale (GAIS), patients′ satisfaction, 3D imaging, and RCM assessments at baseline and 6 months after the last laser session. Results: Although a clinical improvement of SD was observed in 81.4% of patients according to physicians′ GAIS, only 66.6% of patients reported subjective improvement and satisfaction after treatment (P = 0.04). 3D imaging revealed a significant improvement in terms of skin texture (P < 0.001) and mean SD depth (P < 0.001). Otherwise, RCM highlighted collagen remodeling and the appearance of new dermal papillae in all the treated SD compared with baseline. Conclusions: The present study confirms that PLS represents a safe treatment option for SD; herein, we report morphological documentation of skin variations after PLS treatment. Lasers Surg.

The influence of social media on patients’ perception of aesthetic treatment outcome. Satisfaction with tattoo removal: A model
No full textThe level of patient satisfaction following tattoo removal often varies and frequently diverge from clinical objectivity. This study assesses how much social media can influence patient satisfaction after picosecond laser (PSL) tattoo removal, in light of the growing influence they have on consumers. Twenty-seven patients were treated with PSL for removal of professional black tattoo. Two groups of patients were identified: those who were already being treated at our institute or had been referred by other physicians (group 1) and those who found us through social media (group 2). Clinical improvement was evaluated 8 weeks after the final laser session and patients’ satisfaction was assessed. In both groups, clinical results were homogeneous; however, Group 2 patients’ subjective Global Aesthetic Improvement Scale scores were lower than those reported by clinicians (p=0.035), while Group 1 was globally more satisfied (p<0.001). We can affirm that the influence of social media on the perceptions and expectations of patients can affect their level of satisfaction. Particularly for people who are influenced by social media, it is essential to provide explanations prior to laser treatments, in order to clarify what may actually be expected from laser sources
