No more torture of this barbaric technique of hair removal that involves tearing our hair with a dry and painful gesture.
From now on, we can have a painless and lasting hair removal with pulsed light hair removal (or flash lamp). Explanations and instructions.
Pulsed light: how does it work?
The depilation is done by the emission of light and the absorption of this light by a target: the hair.
The light reaches 70 ° C and destroys (only) the hair, eventually leading to a near non-regrowth of it. In the hair, it is the pigment (melanin) that will capture the light and thus heat.
The technical specificity of pulsed light, relative to the laser, lies in the wider emission spectrum (several wavelengths instead of one with the laser) of light.
How is a session of pulsed light hair removal?
Not being considered as a medical act, pulsed light hair removal is generally performed in beauty centers.
Before any session, take some precautions:
- Shave the hair in the affected area about 2 to 3 days before the session (the darker the hair is, the more it is spotted by the light).
- Anticipate the sensations of heat and tingling by applying for the more sensitive areas, such as the shirt or the face, an anesthetic cream (prescribed by a doctor).
- Protect your moles and wear anti-radiation goggles (provided by the facility).
Once lying in a cabin, the professional diffuses the flash light on the areas to be treated for 5 to 15 minutes.
You only feel a little tingling and a feeling of warmth. Be careful, sensitive areas can be a little more painful.
How many sessions do you have to do before getting results?
We space sessions of 1.5 months on average at the beginning to 2 months - 3 months thereafter.
After two years, this period increases to 6 months, then 12 months.
To know: we avoid a session 2 to 3 weeks before exposure to the sun and we wait at least 1 month on his return.
Is pulsed light effective?
It is necessary to wait 3 sessions before the first signs of effectiveness are visible.
Each session burns a limited percentage of hair. As of the fifth session, approximately 90% of the hairs are eliminated.
a pulsed light hair removal is almost definitive on the armpits and the jersey and durable on the other zones.
It must be remembered that the efficiency varies according to the setting and quality of the machine. For information, a device with a medical CE offers more guarantees than others.
Contraindications?
Pulsed light hair removal is not suitable for white, discolored or clear hair and is not recommended for dull, mixed or black skin. Similarly, it is to proscribe on tanned skin (naturally or using self-tanning products).
Finally, it is contraindicated for certain pathologies or treatments:
- Pregnant or lactating woman.
- Diabetic, epileptic, cardiac.
- People with a blood disease.
- People undergoing anticoagulant treatments, antibiotics or photosensitizing drugs.
True-false on pulsed light hair removal
- The laser is more effective on black hairs on white skin .
True: the laser is particularly effective on brown hair (with a lot of melamine) on a white skin because the contrast between the hair and the skin intensifies the "capture" of light.
- Pulsed light hair removal sessions are cheaper than laser.
True: practiced in aesthetic centers with shorter sessions and therefore more profitable, the pulsed light hair removal practices prices a little cheaper than the laser.
- Light depilation is effective on white hairs.
False: The absence of melanin compromises heat transfer and renders this technique ineffective on white hairs.
- Pulsed light hair removal is more suitable for blonde hairs and down than laser.
True: A laser can only deliver a single wavelength, unlike pulsed light that sends out a multitude of wavelengths and increases the chances of adapting to as many hair colors.
