LTFLASH®

LTFLASH DERMEOThe LTFLASH®, designed for professionals in the aesthetic sector, is a compact pulsed light device which offers new treatment opportunities (treating customers at home). 

The LTFLASH® device enables the user to perform hair removal treatments on light and dark skin and skin rejuvenation. 

The LTFLASH® device possesses the DHR "Dynamic Hair Removal" mode, which enables the operator to treat an area by scanning it.

Through its concentrated technology, the LTFLASH® device provides the same energy over the entire surface of the optical guide. 

Its efficiency and safety have been proven by dermatologists' feedback, and by a clinical study carried out on voluntary patients at the hospital la PITIE SALPETRIERE in Paris. The device offers an ease of use which is unique in the market.

Technology

shema-penetration-LTFLASH

The technology of pulsed light is based on the selective photothermolysis principle (photo: light, thermo: heat, lysis: destruction, selective: targeted). It transforms electrical energy into intense bursts of radiant energy through a lamp containing a noble gas, xenon. The resulting radiation is a bright flash of high intensity, which covers a spectrum of wavelengths ranging from visible light to close infrareds (spectrum band from 420 nm to 1200 nm). The polychromatic light is absorbed by chromophores (melanin, oxyhemoglobin, porphyrin, water), which are pigments absorbing light and reacting to the photothermal effect. This is the phenomenon that leads to the cells destruction or changes. With the cooling water running through the lamp, the infrared light is absorbed, the heat is dissipated and therefore is not transmitted to the skin. It is only the chromophore that is targeted by the light so there is no risk of burns.

Various filtrations are available depending on the targeted chromophore (porphyrin, oxyhemoglobin, melanin, water) and the desired application.

Principle

IPL operates according to pulses ; the emission as a train of pulses, can cut a bright flash in several pulses in order to distribute energy. The time between each pulse corresponds to the Thermal Relaxation Time (TRT) and thus allowing the skin to dissipate heat. To achieve results, the maximum energy is needed.

The balancing pulses provides the same energy density from the first to the last pulse.

Another feature of the pulses is the "square form" also called a "Simmer", it allows the device to immediately reach the energy level required and to keep the level constant.

Treatments

The efficiency and safety of DERMEO devices have been proven by cosmetic physicians, and by a clinical study carried out on voluntary patients of the hospital "la PITIE SALPETRIERE".

schema-hair-removalThe hair is mainly composed of keratinocytes that synthesize keratin, and melanocytes which are responsible for the production of melanin. In photo-depilation, intense pulsed light is absorbed by the melanin (coloured pigment) contained in the hair. This is then channeled to the “root” (hair shaft, hair follicle, epithelium and matrix). When the light meets a chromophore, it is converted into heat; the thermal effect destroys the germ cells responsible for hair growth. These are located approximately 4-6mm under the skin.  Hair acts as a conductor of energy to these cells, therefore, the hair must be in the “anagen” phase (phase at which the bulb and the hair shaft are attached to the root). Light skin contains a small amount of melanin but by using a wavelength of 620-1200nm the melanin in the hair absorbs the light. Multipulse is an important parameter that reflects the TRT (Thermal Relaxation Time) of the skin which is relative to the target chromophore which avoids the risk of burns caused by single flashes that are too long.

Protocol

Treatment time: 8 to 10 sessions are required at interval of about 4 to 6 weeks depending on the zone treated.HR: 620 - 1200 nm

Proven results

According to our clinical study conducted by the Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO), on volunteers recruited from the Hospital Pitié-Salpêtrière in Paris, the subjects who completed treatment for hair removal showed excellent results: 80% of hair treated was gone after 2 or 3 sessions.

The hair is mainly composed of keratinocytes that synthesize keratin, and melanocytes which are responsible for the production of melanin. In photo-depilation, intense pulsed light is absorbed by the melanin (coloured pigment) contained in the hair. This is then channeled to the “root” (hair shaft, hair follicle, epithelium and matrix). When the light meets a chromophore, it is converted into heat; the thermal effect destroys the germ cells responsible for hair growth. These are located approximately 4-6mm under the skin.  Hair acts as a conductor of energy to these cells, therefore, the hair must be in the “anagen” phase (phase at which the bulb and the hair shaft are attached to the root). Dark skin contains a higher concentration of melanin. From the cornea layer, the skin can act as a competitive chromophore when targeting the melanin in the hair. The specific filtration for dark skin (phototype IV, V and the begining of VI) promotes the absorption of the pulsed light by melanin contained in a hair anchored in tissue, and thus leads to a high level of effiency of the treatments. A specific filtration is necessary up to 690 nanometres, and is limited in exposure using a range of wavelengths from 420 to 690nm which allows the destruction of the bulb, while preserving the skin.

The multipulsed mode is an important parameter that reflects the TRT (Thermal Relaxation Time) of the skin which is relative to the target chromophore which avoids the risk of burns caused by single flashes that are too long. To completely preserve dark skin during hair removal treatments it is necessary to increase the number of pulses, reduce the pulse duration and increase the interval between pulses

Protocol

Treatment time: 8 - 10 sessions are necessary with regular intervals of around 4 to 6 weeks according to the area treated.
DS: 690nm - 1200nm for dark skin.

Proven results

According to our clinical study conducted by the Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO) on volunteers recruited from the Hospital Pitié-Salpêtrière in Paris, the subjects who completed treatment for hair removal on dark skin showed very satisfactory results with an excellent tolerance level.

The accumulation of exposure to the sun, smoking, general pollution and aging are accompanied by age related distortion of the structural components of the skin. Fibroblasts, which are one of the main types of cells found in the connective tissue of the dermis, are responsible for the renewal of collagen and elastin. The natural production of collagen starts to decrease from the age of 25 and it further declines from the age of 40. It is important to stimulate cell renewal to prevent the skin from aging in order to take anti-aging action. Intense pulsed light emits the flash of pulsed light at a wavelength of 535nm allowing the stimulation of fibroblast cells. This thermal denaturation of collagen induces neo-collagenesis ; the inflammatory response that results from heating the skin creates a cascade of reactions leading to the synthesis of collagen.

Using IPL for skin rejuvenation stimulates the production of collagen and elastin. There is also an improvement in skin elasticity, reduced pore size and a reduction in fine lines. The skin is radiant and toned, the face is reshaped and the skin texture is improved. The results are visible from the first session.

Protocol

Treatment time: 4 - 5 sessions are necessary at intervals of 2 to 3 weeks between sessions.
SR : 535 - 1200 nm

Proven results

According to our clinical study conducted by the Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO) on volunteers recruited from the Hospital Pitié-Salpêtrière in Paris, the subjects who carried out a rejuvenation treatment had very satisfactory results; the depth of wrinkles were reduced, the skin tone and complexion improved and pores were tightened.

Clinical Study

To demonstrate the quality and effectiveness of DERMEO’s medical devices, a clinical report was officially established by the GREDECO laboratory. This study was performed on voluntary patients who were recruited at the hospital of Pitié Salpêtrière in Paris (FRANCE).

This study enabled DERMEO to assess the performance of the pulsed light devices on several subjects in the real conditions of consultation.

Regarding efficiency, DERMEO has obtained excellent results (hair removal, and rejuvenation), for almost all configurations and within the due time.

For aesthetic treatments such as rejuvenation, spot care and hair removal on light and dark skin, a high level of safety and efficacity has been proven.
