STFLASH4®

Gamme G4 : STFLASH4 The STFLASH4® system is a pulsed light device for professionals in the aesthetic sector. With a maximum power of 30J/cm² of light output over a surface of max 8.25cm², it allows hair removal on light and dark skin for treatments on face and body.

With its industry experience, DERMEO presents high quality systems reuniting the most recent technological innovations for optimal performance

  • The EASYLAMP® is the only water cooled lamp that is directly interchangeable by the operator in only 10 seconds. This avoids the device being temporarily unusable until a technician arrives to deal with it.
  • The optical blocks, interchangeable in only 5 seconds, one of 8.25cm² is the biggest on the market which saves time and increases profitability.
  • A train of pulses brings more comfort and safety towards treating darker skin tanned skin and mixed skins up to phototype VI.
  • A square pulse allows controlled and instant power which gives effective and long lasting results.
  • Balanced pulses evenly distribute the energy for comfort.
  • An upgradable monitoring system with straight forward updates that can be implemented by the user themselves.
  • The USB port allows the network and the transfer of information.
  • The SD card reader allows updates which can be done on-site.
  • Profile management: allows the same device to be used by several employees with different levels of access to different treatments.
  • Preprogrammed treatment protocols: optimised, secure and effective and even more.
These innovations benefits from several certifications, marks, labels and patents.

The STFLASH4® device, thanks to its technology, supplies the same fluence on the whole surface of the optical guide. One single treatment of flashes is necessary to obtain a progressive definitive result.

Technology

Intense Pulsed Light (IPL) is a technology that combines a power generator with a cooling system ; this comes with a handpiece which contains a xenon lamp and an optical guide which has a filter. This then projects an intense light. This technology is based on the principle of selective photothermolysis (photo = light, thermal = heat, lysis = destruction, selective = targeted). The radiating energy that results is a high intensity flash of light that covers a spectrum of wavelengths corresponding to visible light and near infrared (spectral range 420nm to 1200nm). Polychromatic light is absorbed by the chromophores (melanin, oxyhaemoglobin, porphyrin and water), pigments that absorb light reacting to the photothermal effect which causes either cell destruction or changes to the cell. Thanks to a water cooling system for the lamp, the infrared rays are absorbed, heat is not transmitted to the skin, only the chromophore is targeted and there is no risk of burns.

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

Principle:

train de pulse Intense pulsed light operates using pulses of light. Emitted in the form of a train of pulses, it allows a bright flash to be cut in to several pulses to distribute energy. The time between each pulse corresponds to the TRT (Thermal Relaxation Time) and allows the skin to dissipate heat.

Balancing the pulse evens the energy density from the first pulse through to the last.

Another characteristic of pulses is a “square” or “simmer”, which achieves a level of energy that is immediately requested and keeps this energy constant.

Difference IPL / laser

Unlike lasers, intense pulsed light photons are incoherent; they do not follow a predetermined path, this results in an unfocused beam of light. With a polychromatic spectrum, pulsed light can target multiple chromophores through the use of different filtrations allowing the realisation of different treatments.
The wavelength chosen will influence the depth of light penetration in the different layers of the skin allowing the pulsed light to target the desired chromophore.

Treatments

According to our clinical study conducted by the Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO) on volunteers recruited from the public Hospital Pitié-Salpêtrière in Paris

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 channelled 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.

Treatment safely on dark skin

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 channelled 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). The use of a specific filter (DS 690 nm) treatments on dark skin. The specific filtration for dark skin promotes the absorption of the pulsed light by the melanin, and thus a high level of efficiency.

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. 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 to 10 sessions are required at interval of about 4 to 6 weeks depending on the zone treated.
DS: 690 - 1200 nm 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

* In the United States of America the authorized claims by the F.D.A. for our device are: removal of unwanted hair from phototype skin I to V.

Clinical study

To prove the safety and efficacy results of aesthetic and medical devices DERMEO, a clinical study was officially directed bythe Group for Research and Evaluation in Dermatology and Cosmetology (GREDECO) on volunteers recruited from the Hospital Pitié-Salpêtrière in Paris. During twelve months, researchers, dermatologists and doctors performed tests on all DERMEO IPL devices applications, like:

  • Hair removal treatment on light skin,
  • Hair removal treatment on dark skin.

Satisfactory to very satisfactory results were obtained for all directions for both the patient and the practitioner.
