How does a laser burn occur?

Various factors can cause a burn after a laser hair removal session. Before looking at these responsible factors, it is necessary to understand how the laser works on the skin.

During a laser hair removal session, the laser projects a light beam that is absorbed by the melanin in the hair to destroy the hair bulb. As mentioned, certain factors can cause burns, some of which are:

A poorly adjusted laser

Indeed, if the laser's power is not adapted to the skin type or hair color, the risk of burns increases. Darker skin contains more melanin, and due to excessive absorption of laser energy, overheating of the epidermis can occur.

Excessive heat

If the laser heat is too intense and remains concentrated on the treated area for too long, it can damage the surrounding skin and thus cause a burn.

An unsuitable laser

If the laser is not suitable for the skin type and/or hair, it can cause lesions. Indeed, there are lasers that are better suited for light skin, others for dark skin. It is important to have a laser hair removal session performed by a qualified person.

Inadequate precautions before and/or after the session

If you exposed yourself to the sun before or after a laser session, if you applied unsuitable products to your skin, if you used perfume, deodorant, if you did not strictly follow the instructions, all of this can lead to a risk of burns. It is essential to strictly adhere to the process and safety instructions during a permanent laser hair removal treatment.

Laser cooling system failure

The lasers used today are all equipped with cooling systems. If this system is not activated or if it fails, it can inevitably cause burns. On the one hand, if the skin overheats, and on the other hand, if the application is prolonged and intense on the same area, even if the cooling system is working well, there can be a risk of cold burn due to improper scanning of the laser over the treated area.
