Laser hair removal - one of the newest methods of removing unwanted hair. The operating principle of hair removal is very similar to the principle of laser hair removal - that's just, unlike laser hair removal, Laser hair removal involves the destruction of hair follicles and preventing hair growth by means of a high-intensity light. The directional flow of light provokes the thermal damage to the hair follicle, destroying it by heating.
Laser hair removal is suitable for removing unwanted hair in any area of the face and body for both women and men. Keep in mind that epilation does not guarantee permanent removal of hair growth: while the skin remains smooth for a long time, epilation performed regularly, only reduces the number of hairs in a given area with each subsequent procedure, but does not help get rid of unwanted hair forever.
The procedure for hair removal
Hair removal procedure itself is quite simple and is accompanied by a minimum of discomfort - for the prevention of pain in the area treated by the light beam, sometimes applied anesthetic for topical application. In addition, the skin at the site of epilation before the procedure can be treated with a special cooling gel that minimizes discomfort during the procedure. During hair removal must always wear protective goggles.
The duration of the procedure of hair removal is an average of twenty-five minutes, however, this figure is strictly individual and depends on the number of hairs and the size of the area to be hair removal
Hair removal: perfect skin without hair
. Since epilation effect on the deeper layers of the skin, the surface layer of the skin is not damaged in any way - only in rare cases after the procedure may be a slight skin irritation.
How effective epilation
The effectiveness of hair removal, as well as hair removal
Hair Removal: Which method is right for you?
with a laser, it depends on several factors. Among them:
- Natural skin tone although epilation is suitable for almost any color, most effective procedure in cases where the nature of the skin is enough light.
- Hair color: is how dark or light hair, is crucial for the effectiveness of hair removal. It's best results when the hairs are dark. To remove the gray or very light hair epilation is not suitable.
- The thickness of the hair: Laser hair removal is most effective in cases when the hairs are not only dark but also quite thick: the thinner the hair, the less effective the treatment.
On average, in order to achieve optimal results - that is, to grow hairs were as invisible, and the skin remains smooth for a very long period of time - must be a minimum of six treatments of hair removal with a certain interval between them. If the skin is dark or light hair may require more hair removal sessions. From time to time re-doing photoepilation necessary also because the effectiveness of the procedure depends on the phase of hair growth: each one removed during the procedure different hair growth phase, so will have to repeat the procedure several times.
Side effects and safety
Hair removal using light of high intensity is considered one of the safest procedure to remove unwanted hair, but hair removal and have some nasty side effects. One of the most common side effects of treatment - a slight reddening and swelling of the skin at the site of the impact of the light beam: this phenomenon is perfectly normal, and redness disappears on its own within a few hours. Within a few days after the procedure can be observed a slight irritation, itching and redness of the skin - symptoms similar to symptoms of sunburn
Sunburn: severe blow to the body
. Only in very rare cases, epilation may cause more significant skin disorders - including hyperpigmentation, a darkening of the skin exposed to light, and hypopigmentation - that is, on the contrary, clarification of certain parts of the skin.
Classification of skin types
- Type I - skin always burns in the sun and never tans
- Type II - skin always burns in the sun, sometimes tans
- Type III - sometimes skin burns in the sun, always tans
- Type IV - The skin never burn in the sun, always tans
- Type V - Leather with moderate pigmentation
- Type VI - Black
To prevent the absorption of light energy of skin pigment, it is necessary to use a device that emits light corresponding to the color of the hair (the length of light waves) and destroys the cells responsible for hair growth (located in the root of the hair follicle). All lasers emit light of different colors (different wavelengths) depending on the used active material. Thus, the ruby laser emits red light (695 nm), alexandrite laser - infrared light (755 nanometers).
For example, using a ruby laser can remove only the dark hair in people with light skin, hair and mainly on the face, where the skin is lighter. If black hairs grow on darker skin, laser energy is absorbed by pigments of the skin, hair and destruction does not occur. Similarly, if the hair is colorless or light, it will also be insensitive to the laser radiation.
Laser systems based on the action of high-intensity light pulses are converted into non-invasive procedure photoepilation long body hair removal. Unlike conventional fixed laser light wavelength, laser systems with high intensity light pulses such features:
- Adjust the wavelength of light depending on the color, hair color and depth of the hair follicle of each patient.
- Effectively removes hair almost any color and density, from subtle to severe.
- Removes hair in patients with any skin type
How to determine your skin type
- Remove the hair anywhere on the body: the face, armpits, bikini area and perineum, and so on.
Laser systems based on the action of high-intensity light pulses
Before the procedure, hair removal operator adjusts the length of light waves in accordance with the pigmentation of hair to be removed and the surrounding tissue. Then the hair follicle to selectively direct a pulse of light of high intensity without damaging the epidermis.
During the procedure, gradually increasing the temperature of the radiation, the energy of the light pulse of high intensity absorbed by the pigment of the hair, and part penetrates the skin and is absorbed directly to the hair roots. This distribution of energy - a unique feature of laser systems with high intensity light pulses - help permanently destroy the cells responsible for hair growth.
After procedures for the destruction of hair follicles are removed along with the natural physiological process that provides a long-term effect of hair removal.
