Intense pulsed light (IPL)
The intense pulsed light (IPL) technique is a recent evolution of the laser technique. It involves emitting strong, long-wave pulses to the surface of the skin in frequencies controlled by highly technical equipment. These programmed parameters vary according to the treatment being used.
The best opto-electronic treatments are obtained by combining the optical effects of IPL and bi-polar radio-frequency (RF). The synergy between these two methods, called Synopton®, triggered by an advanced electronic system and proven parameters, will safeguard the skin while focusing efficiently on the chosen targets. This is the most advanced technology for this application (see scientific references below).
Each flash produces calibrated impulses of large spectrum luminous light, the energy of which is absorbed by the substances contained in the target, also known as chromophores:
- the melanin in the hair and the junction of the derma- epidermis
- the oxy-hemoglobin
- the water into the skin layers and cells.
Thanks to Synopton®, the effect of the radio-frquency, independant from the melanin and from the color, is exponentially added to the effect of light for an increased efficency of the treatment.
For IPL lifting and skin rejuvenation, the wave length used specifically for this treatment stimulates the production of collagen, changes the connecting tissue, closes dilated pores and improves the elasticity of the skin. This results in a pronounced lifting effect. There is a noticeable visual improvement of the skin surface. The color becomes uniform. Brown marks are reduced and may even disappear, for example on the back of the hand.
For permanent hair removal, the chosen wave length is absorbed by the melanin in the dark hairs which are in the anogen growing phase.
The thermal effect which reaches 70°C destroys the hair at its root, by selective thermolysis, in excellent, comfortable and safe conditions without secondary effects. There is only a pricking sensation.
This technology will also heat the skin surface. In order to minimize this unwanted side-effect, and in order to avoid pain due to a sensation of burn, the crystal in contact with the skin is cooled down to -2°C. As a consequence, it is possible to apply the treatment in depth, down to the root of the hair.
Both techniques can be applied to all healthy skin. However the following conditions should be respected:
- the skin must not have any lesion, red patches or skin diseases
- there must be no medication treatment (antibiotics, Roaccutane®, vitamins A and K, medication encouraging hair growth, etc.)
- no self-tanning substances should be being used (gels, creams, tannings, etc.)
- one should not be heavily tanned or have a sun-allergy
- exposure to the sun must be avoided two weeks before and two days after a session
- before a session the skin should not have been sensitised (for example by exfoliation, etc)
- there should be no hair removal using the waxing method before a session, because it is essential that the hair is there in order to direct the light and the heat directly onto the follicle
- this technique should not be used during pregnancy.
