  How does it work?

  Bursts of light at different wavelengths are delivered to the treatment area of the skin at preset lengths of time,
  calculated in milliseconds and called “pulse duration”. The light is delivered by a hand piece connected to the main
  device and fitted with a xenon lamp with filters and focusing optics. The light penetrates the skin,
  is absorbed by the melanin in the hair which turns it into heat, and conducted to the hair follicle whose
  temperature rises to the point necessary for destruction.

  What is the procedure

  Client/patient is required to shave the treatment area 24 hours before each successive session. A gel is applied
  onto the skin in the treatment area. This gel will act as a refracting agent, directing and concentrating the light
  beam to the target. After deciding on the starting point of his treatment, the practitioner gently rests the quartz
  lens of the hand piece onto the skin and flashes a first “pulse”. He then moves the quartz to the next spot and
  so on until treatment is completed.

  How many treatments are needed?

  The hair cycle is divided into 3 distinct phases:
  •    Anagen, when the hair follicle is attached to its root and blood supplied by nutrient vessels.
  •    Catagen, when the hair separates from its nutrient source, and starts sliding upward into its protective sheath.
  •    Telogen, when the hair is expelled entirely from the sheath and falls out.
  A new hair then starts growing to replace the fallen one (new “Anagen phase”). For obvious reasons, hairs can only
  be efficiency and permanently removed when they are attached to their roots and their nutrient source is active,
  therefore in the “Anagen” phase only, as our target is the hair follicle and its nutrient source. In different
  parts of the human body, a different percentage of hair is in the “Anagen” phase at a given time. For example on the
  head, 80% of hair are in the “Anagen” phase at the same time, while on the legs, only 30% of hair are in the
  “Anagen” phase at the same time… This explains why several treatments will be needed in order to achieve optimal
  results in each targeted treatment area. Depending on client/patient, an average 3 to 7 sessions should be sufficient
  to successfully remove 90/95% of unwanted hair. Thereafter, and only if need be, 1 or 2 “maintenance” sessions
  could be planned at 6 months/1year intervals to perfect the treatment.

  How long does one session last?

  It all really depends on the size of the proposed treatment area. For example the following times per session are the
  standard (for all the devices on the market, including Yperion’s “L series”) in comparison with Yperion’s new
  generation of “IPL” equipment, the Or Light , where treatment time has been drastically reduced:
         2 minutes        Upper Lip        Just a few seconds
        20 minutes        Armpits          5 minutes
        25 minutes        Full Bikini        6 minutes
        30 minutes        Arms              8 minutes
        45 minutes        ½ Legs          10 minutes
        90 minutes        Full Legs        20 minutes

  Does it hurt?

  Sensitivity to light treatment varies from one individual to the other as each of us obviously has his own level of
  pain tolerance. The sensation of pain is extremely variable from one individual to another; it depends on: 
  •    individual sensitivity
  •    The area of the body (the face is more sensitive than the legs, the centre of the face more sensitive than the
        sides of the face)
  •    The skin pigmentation. The more the skin is pigmented the greater the epidermis will be heated. Light skins are
        the least sensitive
  •    The hair density. The more hairs there are per cm2,  the greater the sensation of heat (density of a man’s beard
        455 hairs/cm² and legs 50 hairs). This explains why the pain sensation diminishes with the number of sessions.
  The darker the skin, the greater the pain. In general, the sensation is that of an elastic band snapped against
  the skin. For most people a LOT less painful than waxing. Most will feel NO pain at all. To put the record straight,
  hair removal using “IPL” technology is no more, even less painful than waxing or other antiquated and
  repetitive hair removal methods.

  Are there any undesirable side effects?

  The vast majority of clients/patients do not experience any kind of side effect. Most of them can resume work just
  after completing their session. Right after treatment, client/patient may, on very rare occasions, experience some
  form of minor swelling, and sometimes skin may show some redness or turn pink and slightly sore. The feeling might
  be that of a very mild sunburn, and will generally disappear after a day or two. On some very rare occasions, mostly
  intense light delivered to a fair skin can darken it at the flash points. These darkened spots, or hyper-pigmentation,  
  will slowly disappear over time. On the opposite, if the skin pigments absorb too much energy, white or pallid
  patches may appear at the flash points. These pale spots, or depigmentation, will also slowly disappear over time.

  Will it work on me?

  “IPL” hair removal treatment is best suited for Fitzpatrick “1 to 4” skin types, as darker skins with high concentration
  of melanin absorb high quantities of energy and can easily be overheated and burnt, with serious risk of blistering,
  scarring. For the same reason, clients/patients who have been exposed recently to the sun and have tanned skins
  cannot be treated without risk and should wait for their skin to return to “fair” before starting or
  continuing treatment.

  Red hair responds poorly to “IPL” treatment while white and blond hair do not respond at all, for the obvious reason
  that they do not contain sufficient concentrations of melanin, the chromophore indispensable for conducting the light
  and the heat to the target area.

  People who have a history of sensitivity to light-based treatment should refrain from exposing themselves to any
  “laser” or “IPL” device treatment or therapy.

  If the projected treatment area presents any type of infection, client/patient should refrain from exposing it to an
  “Intense Pulsed Light” or any other Light-based treatment.

  Some companies claim their devices can be used on dark skin. Is this true?

  Any device can “theoretically” be used on dark or even black skin, but clients/patients should be treated at such
  low energy, in order to prevent burning or worst, that no significant result will ever be achieved. Clients/patients
  with very dark or black skin are often falsely made to believe that they will enjoy comparable results as people with
  a fair complexion. Unscrupulous manufacturers and/or practitioners may believe or maintain that efficiently treating
  dark or black skin is possible, but according to scientific progress as it stands today their affirmation should be
  considered as naive at best and dishonest at worst. The same applies to manufacturers and/or practitioners claiming
  to be able to efficiently treat red, white or blond hair. Without the presence of melanin, the indispensable
  chromophore responsible for absorbing the light and turning it into heat, how can the follicle and the hair root ever
  be permanently destroyed? Science might possibly be able to give us a response one day, but  as of today:
  significant hair removal for white or light -colored hair, using “laser” or “Intense Pulsed Light” devices is totally
  unconceivable.
