Laser Hair Removal – How To Choose The Best One

When you want to buy a laser hair removal machine, avoid doing a very hard job searching and analyzing various types and brands of lasers, avoid pieces of information that are disguised as advice but are sale statements that promote certain treatments. We will ease this task so you can choose the best hair removal machine possible.

How does Laser Hair Removal work?

Hair removal using laser involves applying a beam of light to a group of hair follicles to burn them, or at least numb them, without damaging the surrounding tissues (selective photothermolysis). The light is absorbed by the hair that carries it through its melanin to its root and, after raising its temperature destroys it.

What is the best laser treatment for me?

This will depend on two factors: The shade of your skin or the type of hair you need to have removed.

You may have very fair skin, or maybe a dark brown or black skin tone; the important thing is that this has to be considered along with the type of hair you want to eliminate: coarse, dark, light or almost not visible. The hair and skin combination will determine the type of laser you should use for the occasion. Remember that, after having all this clear, you should check if the product is on comparoid reviewed so you can select the best value for your money you can possibly obtain.

When can Laser Hair Removal be done?

The process can only be done when the hair is visible and not too long (anagen phase), so you have to perform several sessions (usually from 6 to 11 sessions depending on the areas and your hair type) to be able to treat all the hairs in their respective growth phases.

What differentiates the types of lasers available?

The type of laser is characterized by having a defined and stable wavelength, which defines its color and the depth at which it will enter the skin. Depending on the depth, laser hair removal will either reach the deepest rooted hair or the superficial ones.

Regarding laser hair removal machines, color does matter. Depending on each laser color, the energy of the light will be absorbed differently. Each hair is rooted differently, and this also affects how it is affected by the laser.

Lasers also differentiate according to the wavelength at which they operate.

Here we present a list of the most common types of laser you will find out there:

1.    Ruby Laser

This is the oldest of this class of hair removal machines. It was the first model used for laser hair removal, but its wavelength of 695 nm does not allow it to be applied to hairs with little contrast without burning the skin. Hence, it was only used with clear skins and dark hairs.

It is also not very efficient and cannot reach the deepest hairs, so few sites still use it. I do not recommend it.

2.    Alexandrite Laser

This next generation of lasers, with a wavelength of 755 nm (red), has been active for years and allows extending the treatments to people with lighter hair. It damages dark skins, but is better absorbed by hair melanin and is usually indicated for dark hairs and medium skin types (phototypes 2 or 3). It is somewhat painful to use, and it is mostly used to treat the extensive amount of skin in short periods of time.

3.    Diode Laser

It has a Wavelength of 800-810 nm (dark red), allows to go deeper than its predecessors, while it can be applied to the tanned and dark skin. Phototypes up to type 6 can be treated, although they will always need more sessions than for lighter skins.

4.    Nd-Yag Laser

With a very wide wavelength, can be used for very hard hair that is very deeply rooted.

5.    Photoepilation

Not to be confused with laser hair removal and also known as IPL (Intense Pulsed Light), it diverges from Laser Hair removal in the fact that it has a varied wavelength (from 590 nm to 1200 nm) and it is poly-chromatic. It’s beam of light moves in all directions. It is used to treat varied types of hair, skin photo-types and hairs deeps.
