Laser treatment has become an integral part of cosmetic health care in the modern world. Ranging from hair removal to skin rejuvenation and even eye surgeries, there is no doubt that the advent of laser treatments has revolutionized modern skin treatments. In this article we will discuss laser training for hair removal and skin rejuvenation in brief.
Devices available for Laser procedures
Before discussing how laser procedures are performed, it is important to be aware that there are many devices out on the market that can be used for this treatment. For example, Palomar® lasers are considered the industry standard in laser hair removal and skin rejuvenation.
In order to operate laser devices, specific training is required. This remains the case for whatever procedure is required to be performed. Let’s take a look at some of the basics that will be covered –
1. Understanding the principle
Before administering laser therapy to patients, it is important understand how laser therapy works. Laser therapy for hair removal operates on the principle that specific wavelengths of light which pulsate at a specific frequency are directed towards the base of the hair follicle (in hair removal) and different layers of the skin (in skin rejuvenation). The skin or the base of the hair follicle absorbs light which is then converted to heat. This heat is what produces the change required in the skin (such as removal of wrinkles and scars) and removes the hair from the area.
The advantage is that laser can be directed to a specific point where treatment is required without affecting the surrounding areas. It is therefore extremely useful in managing localised hair or skin problems.
2. Understanding the devices
There are a number of devices that are available to administer laser therapy. We already mentioned the industry-standard Palomar® lasers above. The devices that are used for both skin rejuvenation and laser hair removal are similar though their mechanism of action is slightly different.
Skin rejuvenation using laser treatment, also called ‘photo-rejuvenation’, utilizes a CO2 laser or a YAG laser. These devices emit intense pulsed light (IPL), which is absorbed by the melanin under the skin along with the capillaries in areas where it is applied. This generates heat and destroys the excess pigment and any extra blood vessels that may be present.
On the other hand, laser therapy for hair removal uses a process called ‘selective photo-thermolysis’ utilizing intense pulsed light directed towards the root of the hair follicle. Within the root of the hair follicle are different kinds of melanin and by destroying this, laser therapy can effectively remove hair from several areas and stop hair from going again.
3. Understanding the side-effects
Laser treatment is usually painless and side-effects are very few. Treatments are effective for a very long time though this may vary between patient to patient. The common side-effect is mild skin redness which should be explained to the patient. Preliminary tests assessing for the likelihood of developing problems are sometimes conducted as well.
There are a number of aspects of laser treatments and training that are important to be considered before administering treatment. Different points need to be covered in the training process not ensure the best treatment is offered to the patients.
