Injury risks for cosmetic procedures, laser and IPL

Cosmetic Treatments with laser radiation and Pulsed Light (Intense Pulsed Light, IPL) are becoming increasingly common. The strong radiation can cause skin burns and severe eye damage.

Different types of treatments, laser and radiation from other strong light sources are becoming more common. In the case of cosmetic procedures, like removing wrinkles, hair growth, visible vessel, pigmented lesions and tattoos, the radiation used is so strong that it can cause serious damage to eyes and skin if used improperly. It's about lasers in the strongest laser class, and the flashbulbs, IPL (Intense Pulsed Light). This also applies to variations in the IPL, such as FPL (fluorescent pulsed light).

Lasers in the second-strongest class, 3B, used for example, joint and muscle treatments. These lasers can damage your eyes.

There are also a host of other treatments, in which weaker lasers are used. One example is laser measurement of the feet to produce orthopedic topics. These measurements are harmless.

What are the risks?

The risk of injury in cosmetic treatments with powerful lasers or IPL depends on the type of modifications made. The radiation can cause skin and eye burns. A laser in Class 4 is so strong that it also can cause fires.

The eye is most sensitive body part for laser and IPL radiation. The radiation can cause damage to the retina, which at worst can cause vision reduction or blindness. This damage may be transient or permanent. The radiation can also damage the lens and iris, or cause inflammation of the eye. It is therefore important that both the person doing the treatment and the treated always use eye protection. Protective goggles should be adapted to the current source. The most powerful lasers, Class 4, can cause eye damage, even if you look at a reflection of the laser beam on a matte surface.

But the most common injury is burns to the skin. The darker the skin a person has, the greater the risk. This is because the skin pigment takes up the light and converts it into heat. Burns can cause scars or cause the skin to increase or decrease in pigmentation. Pigmentation disorder can persist from a few months to several years.

Some practitioners claim that their lights are safe and cannot cause damage. This is not true - treatments that have an effect also have side effects. There are no lasers of Class 3B and Class 4 - or IPL's that are harmless.

How can I protect myself?

* You should not carry out treatments close to the eyes, including the area between the eyebrows and under the eyes. The risk of damage to the eyes is great.
* You should not treat dark or tanned skin, as such skin burns easily.
* Do not remove pigment spots in other than a doctor because it may be a skin tumor or precursor to such. Pigment stains should not be removed by laser or IPL
* Do not remove the tattoos, except for doctors, because the risk of burns is significant. There is also a risk of allergic reactions as tattoo dyes are released into the body

Radiation Safety Role

SSM believes that misuse of lasers and IPL is a problem and is therefore reviewing the regulation in this area. SSM has partnered with the National Board on the issue. This is because the issue is part of the whole field of cosmetic treatments and The National Board is an expert authority within health care.
Special focus is directed towards the requirements to be imposed on:

* That the user of the equipment must have sufficient competence.
* That medical liability shall be necessary for the business.

In the current situation is very difficult for the customer to check if a business has sufficient expertise and using the proper equipment so that a safe treatment is guaranteed. "

Control, Cosmetic Treatment

Cosmetic treatments using Class 4 lasers and powerful flash lights that IPL (Intense Pulsed Light) are currently not regulated under law, except for treatments and examinations of the eyes and eyelids (see above and SSMFS 2008:14).

But there are requirements under Radiation Protection Act (1988:220) that those who perform cosmetic procedures, laser or IPL are required to know and follow. The law states, among other things, that he who engages in activities involving radiation shall take the steps and observe the precautions necessary to prevent or counteract damage. Violation of this may result in a fine or imprisonment for up to two years.

Classes of lasers

Lasers, and devices with lasers, are classified according to the laser power and the risks involved in normal use.

In order to use and possession of laser pointers in Class 3B and 4 requires permission from the SSM. It does not require permits for lasers in the lower classes.

All lasers must be labeled with the class. Lasers of Class 2 and up, also must include a warning and warning symbol. The text should be printed with black text on a yellow background.

Lasers in Class 1 are harmless even with long-term exposure. Toys with lasers are limited to Class 1 and if the laser beam is red or green has an output power of up to 0.4 milliwatts.

The class also includes devices that contain lasers of a higher class, but where the laser is built so that no dangerous radiation comes out. Examples include CD players and laser printers. A person who dismantles this type of product, however, runs the risk of exposure to hazardous laser radiation.

Class 2

Class 2 includes only lasers that emit visible radiation, which has a maximum output power of 1 milliwatt. If an unprotected eye is exposed our reflexes make us blink. The natural reaction is fast enough to prevent damage to the retina. Examples of lasers in this class are laser pointers used in lectures.

Class 3R

Class 3R lasers are emitting up to up to 5 mW of radiation is visible. If an unprotected eye is exposed to radiation the limitation value may be exceeded. But the risk of injury by a brief, accidental exposure is small.

Class 3A

This class is no longer used, but is now part of Class 3R. The name of this class have been IIIa or the like.

Class 3B

Permit required for certain uses and certain holding.

The class contains lasers with a power range from 5 mW to 500 mW. Such lasers can be hazardous to the eye in both direct exposure and by exposure from a reflex. Reflections from a matt surface is safe to consider. Powerful green laser pointer and a nightclub lasers are examples of products in Class 3B.

Class 4

Permit required for certain uses and certain holding.

Class 4 lasers include all that is stronger than class 3B, that is to say that they have an output of 500 mW. Here, it can also be hazardous for unprotected eyes to observe an illuminated spot on a matte finish. The class has no upper limit. Lasers in this class can damage the eyes and skin. They also constitute a fire hazard if they have high power. Lasers used for surgery and cutting metals belong to this class, as well as lasers for laser shows.

Class 1M and 2M

Lasers in Class 1M has a power that exceeds what is permitted in Class 1. This applies to both ultraviolet and visible infrared light, but in this class the beam is not narrow but widespread, which means that the limits for unprotected eyes or unprotected skin is not exceeded. But if the light beam is collected with magnifying optics, such as a telescope or a microscope, the lasers in in this class can damage your eyes. Some lasers used in fiber optic communication belong to this class. M stands for magnifier which roughly translates enlarge.

In Class 2M lasers are included those that provide visible light with a higher power than allowed in Class 2, but just like in Class 1M is not thin but widespread. Thus, only a small portion, up to 1 milliwatt, of the total beam hits the eye, which corresponds to a class 2 product.
