Face and neck rejuvenation using an improved non-ablative fractional high power 1064-nm Q-switched Nd:YAG Laser: clinical results in 16 women
摘要： Objective: To evaluate the safety and efficacy of a specific treatment protocol using a new and improved non-ablative fractional high-power 1064-nm Q-switched Nd:YAG laser for face and neck rejuvenation. Methods: Sixteen women, aged 30 to 60 years old, were selected to undergo three consecutive treatment sessions with this new laser at maximum energy (2,400 mJ/pulse, Clear Lift laser?-Harmony XL-Pro, Alma Lasers Ltd.). Face and neck were treated in eight patients, respectively. Each treatment used the same protocol. The efficacy was evaluated by the therapist (TS), the patient (PS), and two separate independent experts who were blind to the study (E1 and E2). Results: According to E1 and E2, the mean reduction in signs of skin aging on a Global Esthetic Improvement Scale was 30-40%. Using a 0–10 points scale, TS and PS mean (range) satisfaction rates were 9.0 (8–10); 9.2 (6–10) for the face and 8.7 (8–10); 8.0 (3–10), for the neck, respectively. The procedure was practically painless, no significant adverse effects were observed, and the patients returned to their daily and work activities without downtime. Conclusion: This laser was safe and effective for face and neck minimally invasive rejuvenation, with excellent results using our usual routine use conditions.

Multiple miliary osteoma cutis treatment response to Q-switched Nd:YAG laser: A case report
摘要： Facial multiple miliary osteoma cutis is a variant of osteoma cutis usually occurring in women with a previous history of acne vulgaris. Successful ablative laser treatment has been reported using both CO2 and Er:YAG lasers among other invasive treatment modalities, like surgical removal. We report a patient with biopsy-proven facial multiple miliary osteoma cutis responding to non-ablative Q-switched Nd:YAG laser therapy. The patient had excellent cosmesis without textural changes or hypopigmentation despite her Asian background after three sessions over 6 months. Multiple miliary osteoma cutis is therefore now amenable to non-surgical non-ablative therapy by using Q-switched Nd:YAG laser therapy reducing the risk of textural changes and hypopigmentation, especially in dark complexion and high-risk individuals. To our knowledge, this treatment approach has not been previously reported.

Fractional 1,927?nm Thulium Laser Plus Photodynamic Therapy Compared and Combined for Photodamaged Décolleté Skin: A Side‐by‐Side Randomized Controlled Trial
摘要： Background and Objectives: Décolleté photodamage is a common condition typically treated with light and energy‐based devices. This study investigated the efficacy and safety of a fractional 1,927 nm thulium laser (TL) alone and combined with photodynamic therapy (PDT). Study Design/Materials and Methods: In a 12‐week follow‐up study, participant décolletés were divided into four treatment areas and randomized to receive a single treatment with field‐directed TL, PDT, combination TL‐PDT, or lesion‐directed curettage control. All actinic keratoses (AKs) underwent lesion‐directed curettage before randomization. TL was delivered at 20 mJ/mb, 500 mJ/cm2 fluence, 5 W, and 8 (n = 6 pts.) or 16 (n = 6 pts.) passes. PDT was performed with 16% methyl aminolevulinate (MAL) creme incubated for 3 h, followed by red light‐emitting diode light at 37 J/cm2. Outcome measures included clinical assessment of overall photodamage and specific subcomponents, assisted by optical coherence tomography (OCT) imaging. Results: Twelve women with moderate to severe photodamage on the décolleté and a cumulative total of 184 thin grade I AKs were included. Field‐directed treatments TL and combination TL‐PDT equally improved the overall photodamage, mottled pigmentation, and rhytides compared with lesion‐directed control (P < 0.05). The skin texture improved by TL alone and was further improved by combining TL and PDT (P < 0.05). Median AK complete responses were similar for field‐directed interventions TL‐PDT (100%), TL (90%), PDT (82%), and lesion‐directed curettage control (52%) (P = 0.464). Patients presented with mild local skin responses, slightly more pronounced when combining TL with PDT versus individual treatments (P < 0.05). No scarring or adverse events were observed. Conclusions: The 1,927 nm fractional thulium laser is an effective, tolerable, and safe field‐directed treatment for décolleté photodamage. Provided alone, TL proved to be as effective as combined TL‐PDT for overall photodamage, while a greater improvement in skin texture was achieved using TL and PDT in combination.
