Background: From the theoretical foundations of laser and energy-based applications for the skin to the development of advanced medical devices, the field of dermatologic surgery has undergone transformative changes.

Objective: To review the scientific and clinical advancement of laser and energy-based therapies within dermatologic surgery.

Materials And Methods: A literature search was conducted to identify important scientific advancements and landmark studies on light, laser, and energy-based devices within the field of dermatologic surgery.

Treatment of Acne With a 1726 nm Laser, Air Cooling, and Real-Time Temperature Monitoring, Software-Assisted Power Adjustment to Achieve a Temperature Endpoint With Selective Sebaceous Gland Photothermolysis.

Objectives: This work highlights the methods used to develop a multi-pulse 1726 nm laser system combined with bulk air-cooling for selective sebaceous gland (SG) photothermolysis using thermal imaging and software algorithms. This approach enables treating to a desired tissue temperature and depth to provide a safe, effective, reproducible, and durable treatment of acne.

Methods: We designed and built a 1726 nm laser system with a 40 W maximum power output, a highly controlled air-cooling device, and a thermal camera in the handpiece, which permits real-time temperature monitoring of the epidermis.

The 595-nm Wavelength Pulsed Dye Laser for Pediatric Port-Wine Birthmarks and Infantile Hemangiomas: A Systematic Review.

Introduction: The 595-nm wavelength pulsed dye laser (PDL) is well-established in the treatment of vascular lesions. In June 2023, it received FDA clearance for the treatment of port-wine birthmarks (PWB) and infantile hemangiomas (IH) in the pediatric population.

Objective: Review the evidence regarding the efficacy, safety, and implications of using PDL for management of pediatric PWB and IH.

Dermal Microcoring for Skin Laxity, Rhytides, and Scars.

Background: Dermal microcoring extracts cores of skin that are small enough to allow healing in a scarless fashion. Its use has been reported in the treatment of skin laxity, rhytides, and textural abnormalities.

Objective: To report the authors' clinical experience using dermal microcoring in a variety of cases.

Clinical Efficacy and Safety of a Thermomechanical Fractional Injury Device for Neck Rejuvenation.

Background: Neck rejuvenation has consistently become a popular cosmetic procedure. While various treatment modalities have been used, a novel fractional thermomechanical skin rejuvenation system was recently developed to create dermal coagulation through direct heat transfer with subsequent neocollagenesis.

Objective: A prospective clinical trial evaluated the efficacy and safety of a thermomechanical fractional injury device (Tixel 2, Novoxel, Netanya, Israel) for neck rhytides.

755-nm Picosecond Laser With Diffractive Lens Array for Acne Scars in Fitzpatrick Skin Types V and VI.

Background: Patients commonly complain about the appearance of acne scars. While various lasers and energy-based devices can offer clinical improvement, many of them are limited in treating patients with skin of color. Concerns exist regarding efficacy and safety, including risks of scarring, prolonged dyspigmentation, necrosis, and burns.

Paired Treatment Using Radiofrequency Microneedling and 755-nm Picosecond Laser With Fractionated Lens Array for Facial Rejuvenation.

Background: Patients frequently complain about fine lines, wrinkles, dyschromia, and photoaging, for which lasers and energy-based devices can treat each of these. Pairing various devices in a single treatment session can be safe and effective, but different technologies, mechanisms, histologies, parameters, and techniques must be considered.

Objective: To examine the utility of a paired treatment regimen using radiofrequency microneedling and 755-nm picosecond laser with fractionated lens array to improve the clinical appearance of facial wrinkles and photoaging.

High-Intensity, High-Frequency, Parallel Ultrasound Beams for Cellulite of the Buttocks and Thighs.

Background: Ultrasound energy can successfully treat fine lines and wrinkles, as well as lift the eyebrow and submentum. Ultrasound waves of high intensity induce thermal injury in the dermis with subsequent tissue remodeling.

Objective: To examine the utility of a novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams to improve the clinical appearance of cellulite on the thighs and buttocks.

Weekly Pulsed Dye Laser Treatments for Port-Wine Birthmarks in Infants.

Importance: Early treatment of port-wine birthmark (PWB) can be life-altering and is often associated with improved outcomes and quality of life. There is growing evidence that shorter treatment intervals may play a role in more rapid PWB clearance; however, the optimal treatment interval has not been established.

Objective: To describe the outcomes of once-weekly pulsed dye laser (PDL) treatments for PWB in infants.

Extension Phase of a Multi-Center, Randomized, Blinded Clinical Study Evaluating the Efficacy and Safety of a Novel Topical Product for Facial Dyschromia.

Background: Dyschromia can be associated with increased production and/or reduced clearance of pigmentation in the skin. Multiple pathways are involved in causality. A novel topical product was recently developed, which contains actives that have been validated through in-vitro and clinical studies to counteract pigmentation related to photodamage, PIH, and melasma.

Clinical and Optical Coherence Tomography Correlation of Vascular Conditions Treated With a Novel, Variable-Sequenced, Long-Pulsed, 532 and 1,064 nm Laser With Cryogen Spray Cooling.

Background: Patients frequently seek laser treatment for vascular conditions. More recently, a novel 532 and 1,064 nm laser was developed to offer greater flexibility.

Objective: A prospective clinical trial evaluated the safety and efficacy of a novel, variable-sequenced, long-pulsed, 532 and 1,064 nm laser with cryogen spray cooling (DermaV, Lutronic, South Korea).

Laser Removal of Eyeliner and Eyebrow Tattoos: Chart Review, Experiences, and Learnings.

Background: Cosmetic tattoos in the periocular area, including microblading, have become increasingly popular. More patients have been seeking laser tattoo removal. A retrospective chart review for the laser treatment of eyeliner and eyebrow tattoos and a discussion of treatment experiences can better inform physicians.

Growing a cosmetic practice with devices and injectables in dermatology.

Growing a cosmetic dermatology practice is an often complex and arduous task. Many factors must be considered to build and maintain a successful clinical practice. Devices and injectables are both integral components to operating a comprehensive cosmetic dermatology practice.
