Using A Laser Machine In Hair Removal

Using a Laser Machine In Hair Removal

Laser hair removal is the most effective technique for painlessly eliminating hair gradually and almost permanently in both women and men. This technique removes the bulb, contributes to the hair’s regrowth, and is located at its root. Therefore, these areas must be heated to 100 ° to transform them into scar tissue and prevent hair re-growth.

In using a light beam, the laser acts on the hair and cross the epidermis to eliminate the hair follicle – responsible for the regrowth of the hair. Melanin, a dark brown pigment contained in the hair, then captures the energy of the laser. Transformed into heat, this is transmitted to the bulb, thus destroying the various structures essential in hair regrowth.

After the destruction of the hair follicle, the hair can no longer grow back. Laser hair removal eliminates about 80 to 95% of the hair and obtains an almost final result. There is no risk of scar or burn when the laser is adjusted and handled by a physician. 

It uses a particular wavelength to target only melanin and avoid touching the surrounding skin. This is called selective thermolysis. The laser is attracted to the melanin in the hair, reducing the risk of burning the skin. 

When the skin is tanned, it can be difficult to use laser hair removal as the risk of minor burns is higher.

Features and Benefits 

Laser hair removal machine removes hair from small and large areas of skin, even in hard-to-reach areas. The device is equipped with a cooling device, protecting the skin from overheating and the appearance of age spots. After implementing 6-10 sessions, the hair growth rate slows down, making it ideal for performing the procedure at intervals of 6 months.

Below is a feature of the machine that can be applied to different skin conditions to achieve different results.

Sorts

There are different types of laser hair removal. The specialist selects the most suitable for a given patient, based on his physiological characteristics.

Diode

Such a laser’s properties make it possible to carry out the procedure even on heavily tanned skin – it affects both melanin and vessels that nourish the hair follicle. Hence, the hair is removed for a long time.

Neodymium 

This laser has the highest power and allows one to get rid of fair hair on any skin type. The device removes both subtle and strong hair, nourishing the skin while influencing a specific area point by point. It is also used for skin rejuvenation. 

Alexandrite 

Radiation generated by the device does not alter the dermis structure and minimizes burns’ risk—ideal for treating ingrown hair. In addition to epilation, it also reduces tattoos, removes age spots, and vascular formations.  

Hybrid 

Three types of lasers are combined in the epilation machine-alexandrite, diode, and neodymium, and equipped with an emitter that works with bars of various lengths. It has a full impact after a session and removes all light hair and dark hair independent of skin tone and texture.

Types of laser hair removal machines

Like electric hair removal, laser hair removal is based on removing the hair at its root by destroying the hair follicle. It is the heat produced by the laser, which will epilate by destroying these follicles.

The technique allows a powerful and profound thermocoagulation. This coagulation of the hair root will allow permanent (or very long-lasting) hair removal from the treated area. The destroyed hairs do not grow back.

Hair removal lasers can be classified into two categories:

1) Thermal effect lasers:

The hair removal laser emits a potent flash of light, concentrated on a small skin area. The dark pigment of the hair (melanin) will absorb this light energy and transform it into heat with, as a consequence, the burning of the hair bulb and the non-regrowth of the hair. This is why lasers do not depilate light-colored hairs.

The same principle allows the pulsed light (or flash lamp) to remove hair sustainably. The surrounding skin, clearer, absorbs less heat and therefore remains unharmed. This is all the more so since a system for cooling the skin’s surface has been used.

2) Photomechanical effect lasers:

In this case, the laser emits a light ray of a specific wavelength, which will resonate with the hair pigment. This intense vibration will deteriorate the hair bulb and prevent hair regrowth.

Is laser hair removal permanent?

Unlike other permanent hair removal methods, this technique allows hair to be treated over a more extended period of time and rapidly because larger areas can be treated in the same session.

The use of the term permanent hair removal is a misnomer. One can instead talk about long-term hair removal since, in reality, this aesthetic medicine technique reduces the number of hairs and the latter’s diameter.

Can laser hair removal be practiced on any skin?

Yes, as long as the right devices are chosen. However, one must be extremely careful with tanned skin because it presents a higher risk of burning or depigmentation. Therefore, it is advisable not to expose the skin to the sun and not use a self-tanner during the treatment. 

Depending on the skin’s phototype and the hair color, use different laser types with specific wavelengths. Here are some examples:

  • Skin with a light phototype of 1 to 4, and your skin is not tanned; use an Alexandrite laser, which has a wavelength of 755 nm. 
  • Dark skin type (4 to 6) or tanned skin, the Nd-YAG laser at wavelength 1064 will be preferred.
