Designed to get rid of hair permanently, laser hair removal is increasingly popular. Therefore, we answer the main questions on the subject.
Laser hair removal is certainly one of the most popular hair removal techniques out there. This progressive hair removal technique is done using laser light energy.
The history of this process began in the last century. Initially, the first laser hair removal devices appeared in the 1970s. The technology was, at first, ineffective, very painful and limited.
In 1983, Anderson and Parrisch introduced the concept of selective photothermolysis in laser hair removal and revolutionized the physical principle of the laser mechanism. Consequently it became effective. There are different types of laser capable of promoting progressive hair removal.
Furthermore, the technique is also called permanent waxing and long-term waxing. Want to learn how it’s made? We tell you right now.
How laser hair removal is done
Firstly, the procedure is carried out using a laser emitting device. It is placed on the hair to be eliminated.
The target is melanin, the substance responsible for the color of the hair bulb and shaft, causing minimal thermal damage to the adjacent tissue. It can be used with anesthetic creams if the person is sensitive to pain. Furthermore, there are devices that present low levels of pain.
When the laser pulse is fired, the energy photons are absorbed by melanin. Heat causes thermal destruction of hair structures. The types of laser most used to perform laser hair removal are the Alexandrite laser, the diode laser (800nm) and the Nd:YAG laser (1064nm).
This type of hair removal can be done by anyone. There are special indications for cases of folliculitis (ingrown hairs) both in the groin, which ends up staining the region, and on the face or any other region of the body.
Furthermore, white skin with thick, dark hair responds better to laser hair removal. Although it can be applied to people of any age, it is best used on adults.
Sessions
Laser hair removal causes pain, but it is bearable. Some studies show that iodine laser hair removal requires an average of 3 to 10 sessions.
Consequently, an average of 5 sessions is recommended, resolving 90% of the hair in most patients. After these 5 sessions, only maintenance sessions will be carried out, every month or every three months.
The legislation does not define which professionals are able to apply laser hair removal. Still, the recommendation is that an evaluation be carried out with a dermatologist before starting treatment.
He will evaluate your skin and decide which treatment is best for it. The tip is to do it with a trusted professional or in a place you know and trust.
Care
Before laser hair removal, you need to take some care. Firstly, the patient cannot be tanned or have seen a lot of sun in the last few days. Consequently, winter is the best time to start laser hair removal.
Furthermore, the patient cannot shave with wax, tweezers or any type of hair removal that removes the hair from the bulb, one month before the laser hair removal session.
People with active infections in the areas to be treated cannot undergo laser hair removal. Furthermore, pregnant women cannot undergo the procedure either. Each session costs between 150 and 1000 reais.
Some complications may occur. They are hyperpigmentation and hypopigmentation, pain, redness, paradoxical hypertrichosis, irritation, itching and the formation of small wounds on the skin.
In these cases, the doctor may recommend local use of corticosteroids, moisturizers and anti-allergens. If the technique applied is not adequate, there is a risk of burns.
