IPL Hair Removal: How Does It Work?

Intense pulsed light is a relatively new and successful treatment to remove unwanted hair.

When properly applied, this treatment allows a reduction of 80% of excess hair.

The light energy, attracted by melanin, reaches the hair bulb and destroys it if it’s in the growing phase (the anagen phase). To avoid burning problems, the IPL machine has a special selective phototermolysis function that allows to differentiate the temperature of skin and bulb: the first will keep inside the security level while the bulb temperature will reach a level high enough to destroy it.

The IPL hair removal treatment works better if:

  • The skin is not dark or tanned
  • The hair is not blond, nor white (the larger the contrast between light skin and dark hair, the better the results)
  • There are no freckles or other skin spots (if there’s a single mole, it will be covered)
  • The hormonal structure is stable (so to avoid, in the future, the growth of new, unwanted hair)
  • The hair is 2-3 mm long
  • The IPL hair removal is performed by an expert and trained operator, that can properly set the machine according to the skin and hair characteristics.

How an IPL hair removal session works:

Before flashing intense pulsed light on the skin, a special gel is applied, that works as energy conductor and as skin protector at the same time. Light is then flashed with the help of a handheld at regular intervals. In a few minutes it’s possible to treat vast areas (like the legs or the the back) but also small ones like the upper lip or the chin area. After the session, the gel and the hair are removed with a spatula, while the remaining hair will fallĀ  in one or two days. After one month, the hair that were not in the active growth phase will grow, and will be ready for another session of IPL hair removal.
