Neck Rejuvenation with Calcium Hydroxylapatite, Hyaluronic A...

Background and Objectives
Aging of the neck is characterized by skin laxity, rhytides, loss of the mandibular contour, widening of the cervicomental angle, accumulation of submental fat, and an increased prominence of platysmal bands, in addition to others, for which many treatment options are available. In the present report, we describe a 1-day combined treatment for neck rejuvenation that addresses these signs of aging without the need for radiofrequency, highintensity focused ultrasound, laser, or other devices.
Materials and Methods
To improve skin laxity, calcium hydroxylapatite in a 1:1 dilution with normal saline or lidocaine (with or without epinephrine) was applied to the neck with a 25-gauge cannula. For horizontal neck lines, hyaluronic acid filler at a total concentration of 20 mg/ml containing 0.3% lidocaine was injected subdermally along the horizontal neck wrinkles using a 33-gauge needle and a superficial serial puncture technique. To treat hyperkinetic activity of the platysma, a total dose of 60-70 U of incobotulinumtoxinA was divided into 60-70 injections. GAIS scores and photos were assessed at 30, 90, and 180 days after treatment.
A 33-year-old female patient presented with horizontal neck wrinkles and mild aging changes with minimal fat accumulation. At 6 months after treatment, she achieved a GAIS score of 2. No serious side-effects associated with the treatment were reported.
In this report, we found combined treatment with CaHA, hyaluronic acid filler, and incobotulinumtoxinA to be effective at treating signs of aging of the neck. Further studies of similar treatments for neck rejuvenation may prove beneficial.

Discover the True Science of Multispecialty Light-Emitting D...

Background and Objectives
Low level light therapy (LLLT) is the therapeutic indication of light energy to achieve a clinical effect in an athermal and atraumatic way, and includes applications in wound healing and pain attenuation. Light emitting diodes (LEDs) have become the light source of choice with quasimonochromaticity giving laser-like target specificity, so LED-LLLT is amassing a growing body of solid evidence in the international literature.
Photobiological basics of LLLT
LLLT involves a direct energy transfer between incident photons and their target cells, boosting thecellular energy pool without causing heat or damage. If such photoactivated cells are compromised, they will be repaired. If they are functional cells, they will perform more efficiently If there are not enough cells, proliferation will occur. In LLLT, wavelength is of prime importance to ensure absorption in the targets, and also determines the intrinsic depth of penetration of the light energy into the target tissue: the light energy must also have sufficient intensity.
The ideal LED-LLLT
system The ideal LED-LLLT system should offer three wavelengths.. 415 nm in the visible blue is useful to control inflammatory acne. 633 nm visible red is particularly useful in photodynamic therapy (PDT) and some aspects of hair regrowth. 830 nm in the near infrared has a wide range of proven targets including, but not limited to, the following: all aspects of wound healing, acute or chronic, traumatic or iatrogenic; attenuation of pain of all entities, acute or chronic; bone repair; nerve repair; sports medicine; and hair regrowth. The HEALITE system (Lutronic Corporation, Goyang , South Korea) meets these criteria and has amassed a good number of panspeciality articles in the peer-reviewed literature. HEALITE embodies the true science of LEDLLLT.

New Concept of Plasma-Forming : PLASMA Physics for Your Skin...

The elements that form the Earth appear in the form of solids, liquids, and gases, transitioning between states thereof with changes in temperature. When there is more energy applied to these three basic state, it becomes the plasma. A plasma is formed when there are equal amounts of ionized particles and electrons, called a quasi-neutral state. Plasma with various properties is used in various applied sciences, industries, and medical fields. When artificially generated plasma is used for industrial or medical use, it can be divided into high temperature or thermal plasma and cold plasma according to the temperature. High-temperature plasma is mainly used for industrial purposes such as nuclear fusion, incineration, and metal cutting, whereas low-temperature plasma is used for light-emitting sources, medical fields, and equipment. The most typical characteristic of plasma is the radicals that are generated in various ways. the radicals generated by plasmas are thought to be more effective in killing cancer cells or sterilizing bacteria. Various radicals generated in the plasma destroy the cell wall of bacteria and have a strong sterilizing effect and interestingly, living tissues are hardly damaged under the same conditions. Therefore, plasma has a very good effect on bacterial-infected tissues, thereby can speed up the wound healing process. In particular, interest in plasma for dermatological treatment is increasing, and cases of use for wound healing have been reported in the UK and Germany. In addition, recently, cases of use in acne, athlete's foot, freckles, and atopy have been continuously reported, and as interest in plasma has increased, efforts to apply it to various skin treatments are increasing. Plasma will continue to be actively researched in more fields in the future. Through such efforts, it will be necessary to develop purpose-built plasma generating devices that are easier and more convenient to use. Furthermore, additional research is needed to determine how unstable plasma energy can be accurately adjusted and to develop quantitative methods with which to measure radicals present in a plasma.
