The use of lasers - what you need to know to avoid misconceptions

The active development of aesthetic medicine requires that specialists in this field be aware of the main distinguishing features, principles of operation and the history of the creation of laser devices.

Knowing this information helps the professional to be safe from common misconceptions and navigate a wide variety of lasers.

Dermatologist, specialist in laser technology in aesthetic dermatology Sergey Voronovsky agreed to share information about the use of lasers in cosmetology with estet-portal readers, dispel existing myths and give his recommendations.

What factors contributed to the use of lasers in cosmetology

S.V.: In the late 80s, the frequency of complications after using phenolic peels and mechanical dermabrasion was too high. Over the decades, tools have been upgraded to find a regimen that won't burn but is effective in dealing with common cosmetic problems.

First came the laser with continuous operation. The occurrence of deep burns prompted the creation of a pulsed laser, later – superimpulse. When the laser exposure time was less than 1ms, the problem of burns was defeated.

We have managed to achieve water evaporation without thermal injury.

It is worth remembering that lasers with an emission time of 1-2 ms exist on the modern market and their use is associated with the occurrence of thermal trauma elements.

Which laser guarantees a short rehabilitation period

SV: There is a common myth that the skin heals faster after using an erbium laser.

This myth is probably related to the fact that erbium lasers were created later than CO2 lasers. But back in the late 90s, the American doctor Goldman conducted an experiment. The sample of patients was 50 people. The doctor polished half of the patients' faces with an erbium laser, and the other half – CO2 laser.

As it turned out, healing proceeded in almost all cases in the same way. Thus, this myth was destroyed 20 years ago.

What are the benefits of ablative skin rejuvenation compared to chemical peels

S.V.: Ablative skin rejuvenation – This is a high-dose treatment that allows you to adjust the exposure to take into account the different thicknesses of the skin in certain areas of the face. The use of chemical peeling does not allow controlling the penetration of the therapeutic factor and reaching the required depth. Also, if we compare the use of deep chemical peels and deep laser techniques, the risks of complications after the use of the latter are much lower.

How many times is laser resurfacing acceptable

SV: Deep laser resurfacing can be repeated after 9-12 months. Superficial laser exposure for the purpose of lifting and leveling wrinkles can be applied with an interval of 2-4 months between procedures. In this case, after each subsequent procedure, the result improves.
