The principle of Laser hair removal
The Laser light is very special, it does that target melanin, a pigment that colors the hair and skin. On very dark or tanned skin, the Laser will heat undifferentiated way skin and hair.
The Laser target remains the bulb, true factory of the hair. Once the latter is eliminated, the hair repels more. In contact with the area to be epilated, Laser light is converted into heat and will move along the hair to go directly to the bulb. From a certain temperature, it coagulates and the hair will fall 14 days later
During a session, slight tingling are felt. The temperature at the surface of the skin remains tolerable while in depth at the level of the bulb can reach up to 150 degrees
The hair cycle
Just like hair, hairs evolve cyclically in three phases: the growth or growth phase (phase anagen), the growth phase (Catagen) and finally the fall phase (telogen).
Only hairs in the phase anagenesis are connected to their bulbs. The hair in phase catagen and telogen are simply clung to the skin, ready to be replaced by a new hair. Laser hair removal will be effective only on the hair in phase anagen because they are the only ones capable of transmitting the necessary energy to the bulb to eliminate it.
During a hair cycle, only 10 to 20% of the hairs are in phase anagen, that is why it is necessary to repeat depilatory sessions every 8 weeks to be effective on the hairs in the growth phase in the next cycle
Laser hair removal is a medical act
Prior consultation is required with an examination well led and a thorough clinical examination for medical contraindications that would defer the epilation or to propose more appropriate alternatives.
Today, diode Laser Technology low fluence allows effectively safe and comfortable way (minimal pain, should be on any type of same the darker skin) because it delivers a low-energy way repeated in order to raise gradually the hair follicle in temperature until it reaches its final coagulation.
At the end of the Protocol, maintenance sessions are to provide one to two times per year. The skin is a full-fledged body that regularly produces new follicles that it will be necessary to deal with
En bref
-
Long lasting epilation
Laser hair removal is not definitive, maintenance sessions are needed one to two times per year at the end of the original Protocol (8 sessions spaced 6 weeks on average)
-
Rather winter
Due to the risk of hyperpigmentation in the event of exposure to UV, it is preferable to conduct its meetings in the autumn-winter, especially on the areas that are likely to expose to the Sun
-
Sun protection
It is obligatory to protect all areas likely to be exposed with on-screen total until the next meeting and, even if the Sun is not at the rendezvous
