Patients with large benign melanocytic lesions located on the neck represent a therapeutic challenge since the neck is a high-risk area for hypertrophic scarring and/or retraction. When treating a benign, extensive and visible melanocytic lesion, the choice of therapy mainly depends on the likelihood of improved cosmesis. We report a case of a 33-year-old woman with a medium-sized Nevus Spilus located on the neck, successfully treated with four sessions of pulsed dye laser. We achieved an excellent clinical and cosmetic result in such a challenging area...

CARS (Coherent Anti-Stokes Raman Scattering) microscopy is an imaging method for living cells visualization as well as for food or cosmetics material analysis without the need for staining. The near infrared laser source generates the CARS signal - the characteristic intrinsic vibrational contrast of the molecules in a sample which is no longer caused by staining, but by the molecules themselves. It provides the benefit of a non-toxic, non-destructive and almost noninvasive method for sample imaging. CARS can easily be combined with fluorescence confocal microscopy so it is an excellent complementary imaging method...

INTRODUCTION: Facial burns occur frequently and depending on the injured skin layers often heal with scars which may cause permanent functional and cosmetic sequelae. Preservation of the sensitive facial skin layers, especially of the dermis is essential for scarless epithelialisation. Enzymatic debridement of deep thermal burns has already been shown to assist with preserving viable dermis. However, up to date, there are no published reports on wound healing and in the long term aesthetic outcome after enzymatic debridement of facial burns...

BACKGROUND: Occupational exposures to ultrafine particles in the plume generated during laser hair removal procedures, the most commonly performed light based cosmetic procedure, have not been thoroughly characterized. Acute and chronic exposures to ambient ultrafine particles have been associated with a number of negative respiratory and cardiovascular health effects. Thus, the aim of this study was to measure airborne concentrations of particles in a diameter size range of 10 nm to 1 μm in procedure rooms during laser hair removal procedures...

BackgroundLocalized cutaneous argyria is a rare skin condition caused by direct contact with silver or silver particles. It presents as asymptomatic gray or blue-gray macules that appear similar to blue nevi. Histologic features include brown-colored or black-colored silver granules in the basement membrane and dermis, most commonly surrounding eccrine glands, elastic fibers, and collagen fibrils. The condition is most frequently observed in individuals who are regularly exposed to small silver particles, such as silversmiths and welders...

There are several therapeutic options to treat congenital melanocytic nevi. The motivations for the treatment of small- to medium-sized congenital nevi located on the face or other sensitive areas are frequently cosmetic. The choice of therapy depends on the operator's expertise and on the likelihood of improved cosmesis. We report a case of a medium-sized congenital nevi located on the lower eyelid, successfully treated with a combination of ablative lasers with a single surgical procedure. We achieved an excellent clinical and cosmetic result...

Early methods of tattoo removal ultimately resulted in unacceptable cosmetic outcomes. While the introduction of laser technology was an improvement over the existing chemical, mechanical, and surgical procedures, the use of nonselective tattoo removal with carbon dioxide and argon lasers led to scarring. Q-switched lasers with nanosecond (10-9) pulse domains were considered to have revolutionized tattoo treatment, by selectively heating the tattoo particles, while reducing the adverse sequelae to adjacent normal skin...

The successful application of lasers in the treatment of skin diseases and cosmetic surgery is largely based on the principle of conventional selective photothermolysis which relies strongly on the difference in the absorption between the therapeutic target and its surroundings. However, when the differentiation in absorption is not sufficient, collateral damage would occur due to indiscriminate and nonspecific tissue heating. To deal with such cases, we introduce a novel spatially selective photothermolysis method based on multiphoton absorption in which the radiant energy of a tightly focused near-infrared femtosecond laser beam can be directed spatially by aiming the laser focal point to the target of interest...

BACKGROUND: Glaucoma is the international leading cause of irreversible blindness. Intraocular pressure (IOP) is the only currently known modifiable risk factor; it can be reduced by medications, incisional surgery, or laser trabeculoplasty (LTP). LTP reduces IOP by 25% to 30% from baseline, but early acute IOP elevation after LTP is a common adverse effect. Most of these IOP elevations are transient, but temporarily elevated IOP may cause further optic nerve damage, worsening of glaucoma requiring additional therapy, and permanent vision loss...

Understanding the high temperature behavior of collagen and collagenous tissue is important for surgical procedures and biomaterials processing for the food, pharmaceutical, and cosmetics industries. One primary event for proteins is thermal denaturation that involves unfolding the polypeptide chains while maintaining the primary structure intact. Collagen in the extracellular matrix of cartilage and other connective tissue is a hierarchical material containing bundles of triple-helical fibers associated with water and proteoglycan components...

Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium...

Submental fat (SMF) accumulation is a cosmetically distressing concern for which there have been recent advances in minimally invasive and noninvasive therapeutic options. In this article, we review the newest treatments available for SMF, including laser-assisted lipolysis (LAL), radiofrequency (RF)-assisted lipolysis, deoxycholic acid (DCA), and noninvasive devices. These treatments provide additional options for patients seeking nonsurgical approaches to treatment of SMF.

Importance: Surgical excision is the standard treatment for cutaneous squamous cell carcinoma (SCC). However, microinvasive SCC (Clark level II) is limited to the papillary dermis, and it should be differentiated from invasive SCC. Ablative fractional laser-primed photodynamic therapy (AFL-PDT) may have enhanced efficacy. Objective: To compare 1 session of AFL-PDT with 2 sessions of conventional methyl aminolevulinate-PDT (MAL-PDT) for the treatment of microinvasive SCC...

Silver nanoparticles (AgNPs) are the most commonly used nanoparticles (NPs) in medicine, industry and cosmetics. They are generally considered as biocompatible. However, contradictory reports on their biosafety render them difficult to accept as 'safe'. In this study, we evaluated the neurotoxicity of direct AgNP treatment in rat hippocampal slices. We produced pure uncoated AgNPs by a pulsed laser ablation method. NP characterization was performed by Ultraviolet (UV) visible spectrophotometer, scanning electron microscope, transmission electron microscope (TEM) and energy-dispersive X-ray spectroscopy...

REVIEW
Austin H Nguyen, Adam M Vaudreuil, Christopher J Huerter
Xanthelasma palpebrarum is a benign periorbital xanthoma with substantial cosmetic and psychosocial burden for patients. Treatment modalities should be considered based on efficacy as well as cosmetic outcome. Laser modalities in the treatment of xanthelasma palpebrarum have not been comprehensively reviewed and discussed. Accordingly, this study seeks to systematically and critically review the available literature discussing laser treatment of xanthelasma palpebrarum. PubMed was systematically reviewed for reports on laser therapy in the treatment of xanthelasma palpebrarum...
