Laser and Light Treatment of Acquired and Congenital Vascular Lesions


    Laser and Light Treatment of Acquired and Congenital Vascular Lesions


    IPL treatment of PWS


    IPL devices are broadband filtered xenon flashlamps that work based on the

principles of selective photothermolysis. The emission spectrum of 515–1200 nm is adjusted with the use of a series of cut-

off filters, and the pulse duration ranges from approximately 0.5 to 100 msec, depending on the technology. The first

commercial system, Photoderm VL (Lumenis, Yokneam, Israel) became available in 1994, and has been used to treat vascular

anamolies. Another, IPL Technology (Danish Dermatologic Development [DDD] Hoersholm, Denmark) with a dual mode

light filtering has also been used to treat PWS. Many other IPL system

have recently been developed, and the appropriate parameters for congenital vascular lesions are being

developed. The IPL has been used successfully to treat PWS (Fig. 39.7),78–80 but pulsed dye laser remains the treatment

of choice.


    IPL technology has also been used to treat pulsed dye laser-resistant PWS. In the study by Bjerring and associates seven

of 15 patients achieved over 50% lesional lightening after four IPL treatments. Most of these patients had lesions involving

the V2 dermatome (medial cheek and nose), which are relatively more difficult to lighten. Six of seven of these

patients showed over 75% clearance of their PWS. A 550–950-nm filter was used with 8–30-msec pulse durations and fluences

of 13–22 J/cm2 to achieve tissue purpura. The 530–750-nm filter can also be used with double 2.5-msec

pulses, with a 10-msec delay and fluence of 8–10 J/cm2. Epidermal cooling was not required. Treatment resulted in immediate

erythema and edema, and occasional crusting. Hypopigmentation was observed in three patients, hyperpigmentation in

one patient, and epidermal atrophy in one patient.


    The basics of body fat


    Let’s start with the basics. Not all fat is created equal. We have two distinct types of fat in our bodies: subcutaneous

fat (the kind that may roll over the waistband of your pants) and visceral fat (the stuff that lines your organs

and is associated with diabetes and heart disease).


    From here on out, when we refer to fat, we are talking about subcutaneous fat, as this is the type of fat that

cryolipolysis targets. A recent study showed that the body’s ability to remove subcutaneous fat decreases with

age, which means we are fighting an uphill battle with each birthday we celebrate.


    From popsicles to freezing fat


    Cryolipolysis machine — which literally translates

into cold (cryo) fat (lipo) destruction (lysis) — was invented, in part, by observing what can happen when kids eat

popsicles. No kidding here. The cofounders of this process were intrigued by something called “cold-induced fat necrosis”

that was reported to occur after young children ate popsicles that were inadvertently left resting on the cheek for several

minutes. Skin samples taken from pediatric patients like these showed inflammation in the fat, but normal overlying skin.

Thus, it appeared that fat may be more sensitive to cold injury that other tissue types.


   
       
            HOW DOES IT WORK?

       
       
            Coolplas Fat Freeze

Machine
uses rounded paddles in one of four sizes to suction your skin and fat “like a vacuum,” says Roostaeian.

While you sit in a reclined chair for up to two hours, cooling panels set to work crystallizing your fat cells. “It’s a

mild discomfort that people seem to tolerate pretty well," he says. "[You experience] suction and cooling

sensations that eventually go numb.” In fact, the procedural setting is so relaxed that patients can bring laptops to do

work, enjoy a movie, or simply nap while the machine goes to work.
       
       
            WHO IS IT FOR?

       
       
            Above all, emphasizes Roostaeian, CoolSculpting is “for someone who is looking for mild improvements,”

explaining that it’s not designed for one-stop-shop major fat removal like liposuction. When clients come to Astarita for a

consultation, she considers “their age, skin quality—will it rebound? Will it look good after volume is removed?—and how

thick or pinchable their tissue is,” before approving them for treatment, because the suction panels can only treat the

tissue it can access. “If someone has thick, firm tissue,” explains Astarita, “I won’t be able to give them a wow result.
       
   


   
       
            WHAT ARE THE RESULTS?
       
       
            “It often takes a few treatments to get to your optimum results,” says Roostaeian, who admits that a single

treatment will yield very minimal change, sometimes imperceptible to clients. “One of the downsides of [CoolSculpting] is

there’s a range for any one person. I’ve seen people look at before and after pictures and not be able to see the results.

” All hope is not lost, however, because both experts agree that the more treatments you have, the more results you will

see. What will happen eventually is an up to 25 percent fat reduction in a treatment area. “At best you get mild fat

reduction—a slightly improved waistline, less bulging of any particular area that’s concerning. I would emphasize the word

mild.”
       
       
            WILL IT MAKE YOU LOSE WEIGHT?
"None of these devices shed pounds,” says Astarita, reminding potential patients that muscle weighs more than fat. When

you’re shedding 25 percent of fat in a handful of tissue, it won’t add up to much on the scale, but, she counters, “When

[you lose] what’s spilling over the top of your pants or your bra, it counts.” Her clients come to her in search of better

proportions at their current weight, and may leave having dropped “one or two sizes in clothing.”
       
   


    Although the mechanism of cryolipolysis is not completely understood, it is believed that vacuum suction with regulated

cooling, impedes blood flow and induces crystallisation of the targeted adipose tissue with no permanent effect on the

overlying dermis and epidermis. This cold induced ischaemia may promote cellular injury in adipose tissue via cellular oedema

and mitochondrial free radical release. Another theory is that the initial insult of crystallisation and cold ischaemic

injury is further perpetuated by ischaemia reperfusion injury, causing generation of reactive oxygen species, elevation of

cytosolic calcium levels, and activation of apoptotic pathways.


    Whichever the mechanism of injury, adipocytes undergo apoptosis, followed by a pronounced inflammatory response,

resulting in their eventual removal from the treatment site within the following weeks. The inflammatory process sees an

influx of inflammatory cells at 14 days post treatment, as adipocytes become surrounded by histiocytes, neutrophils,

lymphocytes, and other mononuclear cells. At 14-30 days after treatment, macrophages and other phagocytes envelope and digest

the lipid cells as part of the body’s natural response to injury. Initial concern was that cholesterol, triglycerides, low

density lipoproteins (LDLs) and high density lipoproteins (HDLs), bilirubin and glucose levels were affected, however these

have been shown to all stay within normal limits following the procedure.


    Four weeks later, the inflammation lessens and the adipocyte volume decreases. Two to three months after treatment, the

interlobular septa are distinctly thickened and the inflammatory process further subsides. Fat volume in the targeted area is

apparently decreased and the septa account for the majority of the tissue volume.


    Patients and treatment areas


    Although all studies show reduction in every area examined, it is still unknown what areas are most responsive to

cryolipolysis. Various factors may play a role in the degree of fat reduction observed after cryolipolysis. The vascularity,

local cytoarchitecture, and metabolic activity of the specific fat depots in questions may play a role.


    There is lack of substantial research to identify the ideal patient or even the ideal area to be treated. Given a modest

(yet significant improvement of up to 25% reduction in subcutaneous fat), it is thought that the best candidates are those

within their ideal weight range and those who engage in regular exercise, eat a healthy diet, have noticeable fat bulges on

the trunk, are realistic in their expectations, and are willing to maintain the results of cryolipolysis with a healthy,

active lifestyle.


    New design Cryolipolysis is

safe for all skin types, with no reported pigmentary changes, and is safe for repeated application. Ferraro et

al. suggest that patients who require only small or moderate amounts of adipose tissue and cellulite removal would

benefit most from cryolipolysis treatment. Contraindications include cold-induced conditions such as cryoglobunaemia, cold

urticaria, and paroxysmal cold haemoglobinuria. Cryolipolysis should not be performed in treatment areas with severe varicose

veins, dermatitis, or other cutaneous lesions.


    HIFU Decide Guide: Which Device is for you?


    High-Intensity Focused Ultrasound also known as HIFU machine

 is a non-surgical, non-invasive treatment procedure that tightens and lifts the skin using ultrasound energy. It

is taken to be a safe and effective procedure for tightening the facial skin.


    HIFU treatment procedure has loads of advantages over the traditional means of facial improvement: painless, zero

incisions, scarring, and recovery time. In addition, it is far less expensive too.


    Granted, HIFU is a popular means of looking better. Little wonder that there are tons of clinics and spas that offer

services they claim can make you look better. However, that's not enough reason for you to jump on the bandwagon of folks

searching for ways to look better


    Why Choosing The Right HIFU Device is Important?


    Be sure to get a professional assessment before you start your HIFU treatment. This is because a professional and

objective assessment from a specialist will help you discover the best form of treatment using the right

multifunctional HIFU that is suitable for you.


    Ultrasound technology is completely safe and has been used in medicine for decades. It works by contracting and

shortening muscle fibers, thus causing the lifting and tightening effect that makes the skin look better.


    Lifting, tightening, and fats melting are natural processes that result in a slimmer face, reduced jowl line & facial

tightening. Confused about how to go about the HIFU facelift treatment in Singapore?


    You will be able to decide on the best HIFU device to use when you finally decide to undertake the treatment. Let’s look

at some of the most common HIFU devices in Singapore.


    What is the working principle for HIFU vaginal machine?


    The vaginal HIFU machine uses an

noninvasive ultrasonic focusing technique to focus on the mucous membrane fibrous layer and

muscle layer directly. Using ultrasonic waves as the energy source and taking advantage of its penetration and focus, the

system will send out ultrasonic energy focusing in the the lamina and muscle fiber layer in a predetermined depth. A higher

intensity of ultrasonic region, called focus region, is formed. In 0.1 second, the temperature of the region can reach to

above 65 ℃ , so the collagen is reorganized and the normal tissue outside the focal region is undamaged. Therefore, the

desired depth layer can obtain the ideal effect of collagen concentration, reorganization and regeneration. Ultimately, the

mysterious effect of vagina tightening is achieved.


    What is the functions for each cartridges?


    1. Vagina tightening head


    4.5mm heads produce the energy directly to the SMAS , make it thermal coagulation , make the SMAS tighten and

lifting, improved the muscle structure from deep to shallow, make better to help the muscle layer restore elasticity

and  tighten.


    3.0mm head the ultrasound penetrates to the skin under the depth of 3.0mm, aim

at  activating the dermal layer’s collagen, effectively enhance the effect of the consolidation of the

outline, but also shrink large pores and reduce the appearance’s wrinkles.


   



    Knowing that you are interested in 3D Hifu

machine
, we have listed articles on similar topics on the website for your convenience. As a professional manufacturer,

we hope that this news can help you. If you are interested in learning more about the product, please feel free to contact

us.3D HIFU is ultrasound energy distance of width, length and depth, which more Comprehensive, three-dimensional. Directly

delivers heat energy to skin and subcutaneous tissue that can stimulate and renew the skin's collagen and thus

consequently improving the texture and reducing sagging of the skin. The high quality handle with German imported

motor can be used for life. Total 8 cartridges supply treatmetn for whole body. 1.5mm is for the forehead and

around the eyes, 3.0mm is for the dermis layer--face treatment, 4.5mm is for the SMAS layer--face

treatment, 6.0mm/8mm/10mm/13mm/16mm for body fat layer. Every cartridge can reach 20000 lines lifetime. 


   



    4D HIFU machine uses the power of High

intensity focused ultrasound to safely lift and tighten skin. High intensity focused ultrasound is a form of energy that is

significantly different than light such as IPL and Lasers or Electrical (Radio-Frequency) energy. HIFU, protects the skin

surface, whilst precisely penetrating at deeper depths and higher temperatures than Radio Frequency for example, treating

beyond the Dermis and Foundation layers, where structural weakening starts.


    Tissue at the target point is heated to 65°C, Thermal Heat is created with the skin tissue creating both spaced ‘wounds

’ and cellular friction - which in turn promotes healing, immediately contracts collagen and stimulates a rapid production.

Over the next 90-180 days, the wound-healing response stimulates long-term tissue and leads to further lifting and

tightening, with results that can last years.


    4D HIFU also helps to improve the tone and all the features of your face such as your eyes, cheeks, mouth, chin and

skin also making it a viable alternative to Botox, with the benefit of being able to maintain facial expression. Excellent

for post surgical face lift to maintain the lift and treat blood stasis, scarring, and numbness. 


    This mode could minimize treatment time achieves the great anti-aging result. It will be leading the new treading in the

market, and help you to expand your business.
