Laser and pulsed light: these permanent hair removal technologies, formerly reserved for pros, are now accessible at home. Painless and practical devices, but whose effectiveness in the long term however remains to be demonstrated.
A growing number of brands offer devices promising sustainable hair removal at home. Two technologies employed are used for several years by dermatologists. "Pulsed light or laser, the principle and the result will be substantially the same on homeappliances, says dermatologist Nina Roos. The projected light is transformed by melanin – pigment giving hair colour dark - thermal energy, which will burn the bulb, the root of the hair. »
Simple and painless
Place the machine on a skin carefully shaved and clean, then press to activate the light flash. The process is fast (an armpit is dealt with in 2 minutes), and painless, limiting itself to a fugitive sensation of heat.
Depending on the area, it is necessary, first time, repeat the operation once every 15days or every month, then way more spaced, as hair fall of themselves. After a fewmonths, one or two annual sessions of maintenance sufficient to maintain clear skin.
Sustainable home hair removal equipment: how effective?
Scientists are not in tune about the effectiveness of these durable epilators at home.First, the studies are still few: "most commercially available devices benefit from a this electronics, and not a medical. '' This means that their effectiveness has not beenmedically controlled,"says dermatologist Nina Roos.
Clinical tests conducted by Philips, one of the manufacturers, certainly results live upto expectations. They indeed indicate a reduction of 86% of the hair after the sixthmeeting of its device to intense pulsed light, the Lumea. However, no indication is specified outcomes over the long term.
Paradoxical growth, a more frequent phenomenon in the case of epilation at home
In certain very specific conditions, laser hair removal can cause the opposite effect to that sought: an exacerbation of hair regrowth paradoxical. Fine animal hair, dull skin, hormonal instability, some delicate areas of the body... Laseristes dermatologistsknow recognize the skins prone to paradoxical regrowth and act accordingly. The phenomenon is therefore relatively rare when sustainable hair removal is practised bya pro, but it could be more frequent at home.
Especially on the duvet and fine hair
In addition, some dermatologists believe that these sustainable hair removal homedevices could encourage the phenomenon of paradoxical regrowth. "On fine hair type down, it takes a high energy to destroy the bulb, explains Dr. Nina Roos. However, these devices, for security reasons, have not sufficient power. Not only the hair does not fall, but heat could stimulate the growth of the hair. »
Sustainable hair removal: a technology adapted to clear skin, dark hair
Laser or pulsed light technologies target a specific population. First of all, some devices are intended only to women. More: melanin being electrically conductive, the effectiveness is conditioned by the type of skin and hair. Also, these devices are shown in light skin and not tanned to dark hair. Use on dark or tanned skin can cause burns.
In the light of the reservations of some dermatologists, it appears prudent to not use home these devices on the fine hairs and fluff.
A perfectly healthy skin
On the other hand, must be perfectly healthy skin: no wound or infection or Mole. Sustainable epilators at home are also contraindicated in pregnant and lactating women, as well as to people with epilepsy, diabetes, a disorder of hemostasis, taking certain medications (pain relievers, photosensitizers, etc.) …
Major equipment
Finally, the purchase price of these epilators at home is an obstacle of a different kind: from 300 euros and up to 1,350 euros. The price difference is explained by moreor less extensive area covered in a 'flash'. Be aware that epilators have a limited life span (average, 10,000 to 40,000 "flashes").
