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 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.

Using an Nd-YAG laser for hair removal provides a temporary result contrary to treatment with pulsed light.

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). 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. Specific filtration is necessary up to 690 nanometres, and is limited in exposure using the range of wavelengths from 420 to 690nm which allows the destruction of the bulb while preserving the skin. The use of an Nd-YAG laser for hair removal only gives temporary results as opposed to IPL.

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

Acne is a skin infection caused by the bacterium Propionibacterium acnes. Gram positive bacilli, which is anaerobic and purple, acts on the sebaceous follicle which when mixed with excess oil releases cytokines, the molecules responsible for inflammation. Using intense pulsed light to treat acne is based on heating the porphyrins produced by the bacteria “Propionibacterium acnes” causing its destruction. Exposure of the porphyrin (chromophore) to the light activates its excited state, resulting in the formation of singlet oxygen, a condition in which the oxygen atom is very reactive in contrast to its ground state which is a triplet state. Singlet oxygen combines with cell membranes to destroy bacteria. The photo-thermal effect also allows for the aseptic treatment of the area. Light filtration between 420 - 1200nm corresponds to an optical penetration depth between 0.5mm and 2mm in order to act intensively on the sebaceous glands that lie on the surface. It filters out all wavelengths except the blue light. In addition, pulsed light works on acne scars by stimulating the production of collagen and elastin by the fibroblasts.

Intense pulsed light is generally indicated for retentional or inflammatory acne of either medium or minor severity. It is used as a substitute to long term antibiotics as drugs such as isotretinoin which are already banned in several countries. Medical treatment of acne using pulsed light is a real medical benefit to patients.

Protocol

Treatment time: 10 - 12 weeks according to the severity. Intervals of 1 or 2 weeks between each treatment.
AR: 420 - 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 of acne have been satisfied with the results.

Eliminate your imperfections

There are two types of pigmented lesions ; “solar lentigo”, which is associated with exposure to the sun, and “senile lentigo”, which is associated with the ageing of the skin, smoking, and general pollution. The two main factors responsible for pigmented lesions are exposure to the sun and the ageing of the skin as we get older. Pigmentation is a result of multiplication of the number of melanocytes, whose volume and activity increases as a result of these factors. Using IPL at a wavelength of 550nm allows an optical penetration depth of 2mm. With this filtration the chosen target is melanin on the skin surface, which then absorbs the light energy resulting in a build-up of heat causing its destruction. After the session, the destroyed particles are then removed by the “phagocytosis” principle which is particle removal by intracellular digestion.

A short flash duration and high power allows protection and comfort for the skin.

Pathological types of pigmented lesions such as nevus naevocellulires and Dubreuilh melanosis cannot be treated with intense pulsed light.

Protocol

Treatment time: 1 - 3 sessions are necessary at intervals of 1 to 2 weeks between sessions.
PL: 550 - 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 pigmentation had very satisfactory results.

Vascular lesions (telangiectasia, erythrose, angiomas, rosacea, small varicosity, diffuse redness) are due to blood vessels that become visible under the skin. The pulsed light is absorbed from a wavelength of 500nm by oxyhaemoglobin, the targeted chromophore in the treatment of vascular lesions. The light is converted into heat, which causes significant heating of the vessel walls and leads to their destruction by photocoagulation and thrombosis without damaging the surrounding tissue. After treatment, the target vessel is then naturally removed from the body leaving no trace.

Intense pulsed light is particularly effective on superficial vascular lesions like blotches, spider veins, redness, etc.

Protocol

A short flash duration and high power allows protection and comfort for the skin.
Treatment time: 1 to 3 sessions are required at intervals of 1 to 2 weeks.
VR dual-band: 500 - 670 and 870 - 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 vascular treatment had very satisfactory results.
