How Do Aesthetic Lasers Work?

by Conor Adan

Today, men and women have many options for rejuvenating their skin safely and get long-lasting results. These options of rejuvenating the skin include laser, chemical peels, and microneedling.

A laser in aesthetic treatments is nothing short of revolutionary, helping the skin by correcting pigmentation issues, free lines, loose skin, and wrinkles.

Expanding the menu of services you get in the aesthetic practice to include laser skin treatment will make your experience exciting and refreshing.

Understanding Lasers

Lasers are basically a complicated field when it comes to aesthetics. It is only with the laser understanding that you will make an informed decision.

In order to have a better understanding of lasers, there are several things to look at. Some of these include the following:

  • Pulse width
  • Frequency
  • Spot size
  • Wavelength
  • Laser medium

Laser Pulse and the Power Bestowed

There are different forms of pulsing for CO2 lasers. UltraPulse is a newer technology that comprises a short pulse duration with a high frequency and pulse power in the aesthetic world.

An excellent device comes with a millisecond pulse width – meaning it’s amazingly fast-firing. Such a device can penetrate a targeted tissue with less collateral damages.

In the cosmetic world, a day or two will make a great difference for many patients. Basically, it’s a matter of taking extra days off work to have the treatment done.

Preferred Wavelengths

You can use laser wavelengths to tune to vaporized colored biologic targets in the human body. The pigment in a brown spot, hair color, tattoos, arteries, veins, and blood vessels can be targeted by one laser wavelength specifically.

The main trick is to produce a specific wavelength, which is required for the application you prefer. A common wavelength usually used in aesthetic laser surgery is 532nm. Cosmetic surgeons use this wavelength to vaporize red tattoos, blood vessels, and spider veins. Other wavelengths include:

  • 1308nm
  • 10,000nm
  • 755nm
  • 1440nm
  • 942nm
  • 2940nm

Types of Aesthetic Lasers

Aesthetic lasers come in different types, distinguished by their mode of delivering lasers and wavelength. You can also modify aesthetic lasers by combining them with other elements, like metals, gases, and precious stones.

Based on how deeper lasers go when treating patients’ skin, they can be non-ablative and ablative. In order to treat superficial layers of the patient, ablative laser treatment will be a suitable option. It helps to get rid of the top surface of patients’ skin.

A non-ablative option like Cutera lasers is suitable for deeper tissues. The best thing about these lasers is that you will not damage the top layer of the skin.

When to Use Aesthetic Lasers

You can break down both non-ablative and ablative lasers into different kinds. A professional and experienced aesthetic surgeon will use different kinds of lasers to tighten the skin.

Basically, skin tightening is a feature of every laser therapy since the aesthetic laser controls minor injuries, which the body naturally repairs through collagen production. Apart from tightening the skin, surgeons also use lasers to:

  • Remove wrinkles
  • Treat lesions
  • Remove tattoo

The Takeaway!

The field of aesthetic laser is big and will continue to grow. If you work in this sector, it will be important to be updated with the newest technology so as to offer your patients the best treatment.

It will also be worthwhile to use external energy measurement devices to check the actual laser output before offering treatment.
