Laser hair removal: history of development and modern times

The beginning of the era of laser hair removal is considered to be 1960 when American physicist Theodore Maiman developed the first solid-state laser.

The first ruby laser

As the active medium of the optical generator, the scientist used a crystal of synthetic ruby.
Although over time laser devices have been improved and made into a universal tool with almost unlimited application, Maiman’s contemporaries called the invention “a solution looking for a problem.”

The first laser with a ruby rod and a silver resonator was revolutionary but expensive and unreliable.

When it was tried on hair follicles, the surrounding tissues overheated, and the long pulse duration greatly prolonged the procedure.

In 1962, the first semiconductor laser diode operating in the visible spectrum was invented. After improving the diode, continuous laser diodes were created that could operate at room temperature.

In 1964, again based on Maiman’s invention, the first device for laser hair removal with an active medium of aluminum-yttrium garnet (neodymium laser) was created.

This was the YAG (solid-state) laser, which was recognized among many similar devices by the FDA, the American agency for product, drug, and cosmetic quality control.

Experiments on diode lasers were conducted as early as the 1980s. The first diode laser recognized by the FDA association was released to the market only in 1995.

The theory of selective photothermolysis for creating lasers

Most of the developed equipment, like Maiman’s prototype, was not effective enough for commercial use.
Safe laser hair removal in the modern sense appeared only with research on the topic of selective photothermolysis.

The theory of selective photothermolysis was proven by a group of American scientists in 1986. However, only in 1996 was a laser device created based on this theory that entered the commercial market.

In short, the essence of selective photothermolysis is that the laser beam affects different skin components differently. The main components that absorb light are water, melanin, and hemoglobin. The absorption spectrum of these components is different.

Knowing this and optimizing the emission spectrum of devices with an artificial light and heat source, scientists managed to achieve an effect only on the follicle, where the maximum amount of melanin is concentrated.

When using laser pulses, melanin heats up and causes the destruction of surrounding cells within the hair follicles. This leads to the death of active follicles and the weakening of those in the resting phase.

Many other procedures that improve skin condition, eliminate pigmentation, wrinkles, and provide tissue lifting are also based on the principle of photothermolysis. For this, neodymium, diode, and alexandrite models are used.

Ruby, neodymium, and alexandrite lasers

In the 1990s, there was a rapid development of laser technologies. Many diode, alexandrite, and neodymium laser devices were produced.
However, some made the hair removal procedure painful. Others were ineffective on dark, tanned skin.

Today, you can experience all the advantages of the latest generation of laser equipment.

The main advantage of modern devices is the ability to adjust pulse characteristics. This allows effective hair removal on different skin types and hair colors.

Moreover, the equipment reduces procedure time and the number of sessions, making your visit to the cosmetology salon comfortable.

Every manufacturer also ensures that the procedure is painless, which is why different skin cooling systems are developed.

Why Motus AX?

The device we use at LaserVille is based on the alexandrite laser. But this is already a new generation of alexandrite lasers, effective on all skin types.
Dynamic epilation, patented by DEKA, is performed in constant motion. It allows you to enjoy all the benefits of modern hair removal – speed, effect, and safety.

It is completely painless: the powerful cooling system lowers the temperature of the nozzle to 15 degrees Celsius.

Therefore, you do not feel discomfort, as with epilation on a conventional alexandrite or diode laser.

At the same time, the system allows for choosing the most effective parameters for different skin types and hair colors. It regulates exposure time, frequency, and pulse duration.

Specialists trained by the device manufacturer understand the differences and subtleties of working with different protocols (built-in settings).

Our device cannot be used when the lamp resource is depleted – it automatically shuts down.

A course of procedures on the dynamic alexandrite laser will give you results that were only dreamed of a few years ago – your skin will be hair-free. Smooth and silky. You’ll constantly want to touch and stroke it.

And you’ll be left with only pleasant memories of the time spent in the epilation salon.
