Laser hair removal: see price and number of treatment sessions

Laser hair removal is a progressive hair removal technique done through laser light energy. The first laser hair removal devices came in the 1970s, but this technology was at first ineffective, very painful and limited. However, in 1983, Anderson and Parrisch introduced the concept of selective photothermolysis (used in laser hair removal), revolutionizing the physical principle of the laser mechanism, leading to greater effectiveness. Today there are different types of laser capable of promoting progressive hair removal.

Other names

The technique is also commonly called definitive waxing, however, this name is incorrect, since epilation does not guarantee that hairs will not return to normal. grow up. The best term to use is long-term hair removal.

Indications

Laser hair removal can be done by anyone who is uncomfortable with their hair or other methods of hair removal with wax and razor blade. There are special indications for cases of pseudofolliculitis (by ingrown) in the groin, which eventually stains the region, such as face, legs or any other region of the body.

In general, white fur with thick, dark hairs respond better to Laser hair removal, but that does not mean that anyone who does not fit these characteristics, can not do laser hair removal. Over the years new technologies have been created, even black or tan skins can do. Dermatologists recommend the use of Diode and ND YAG lasers with long pulse for these cases. The exception is for those with white, red and blond hairs - as the melanin amount is small, there is still no good response to treatment for these cases, however they can be treated, they only need more sessions.

We usually start doing laser hair removal as soon as it is uncomfortable for the person, even in cases of pre-teens. There have been cases reported in the literature on the use of laser hair removal in younger children who had congenital hypertrichosis (which are abundant for genetic reasons) in the lower back (lumbosacral region).

How is laser hair removal

The procedure is performed with the use of a laser emitting device, imposed exactly on the hairs to be eliminated. In laser hair removal, the target is melanin, the substance responsible for the coloring of the bulb and hair shaft, causing minimal thermal damage to adjacent tissue. In people who are very sensitive to pain, we can use anesthetic creams.

When the laser pulse is triggered, absorption of the energy photons by the melanin occurs. The absorbed heat is released by the bulb and the hair shaft, causing a thermal destruction of the structures of the hair.

The types of laser most used to make laser hair removal are Alexandrite laser, diode laser (800nm) and Laser hair removal is often painful, but nowadays there are already devices that have low levels of laser hair removal. ache. In some cases anesthetic ointments and cold air jets may be used to relieve pain.

Laser Hair Removal Sessions

The sessions should be done every 30 or 45 days. "I usually advise to do three to four maintenance sessions after one year, depending on the patient's case," explains Isabel Martinez.

Professionals who can do

The legislation does not define which professionals are able to apply waxing to laser. However, the recommendation is that an evaluation be done with a dermatologist before starting treatment. This professional can carefully evaluate your skin and define the best treatment for it. The advice of the dermatologist Izabel Martinez is to undergo the technique with a reliable professional or in a place that you know and trust.Care before undergoing laser hair removal

"The patient should avoid sunbathing, should not remove the hair with tweezers or wax in the previous month, before the session is done removing the hairs with a razor," recommends the dermatologist Márcia Linhares, member of the Brazilian Society of Dermatology

The person should not be exposed to the sun, should wear sunscreen with a minimum SPF of 30 and always follow the doctor's recommendations.

Pregnant can do?

Hyperpigmentation and hypopigmentation dark, clear), pain, redness, paradoxical hypertrichosis (the sudden growth of the hair, rather than its reduction), irritation, itching and the formation of small wounds on the skin. In these cases the doctor may recommend corticosteroids for local use, moisturizers and antiallergics. If the applied technique is not adequate, there is a risk of burns.

Results of laser hair removal

The effects are seen from the first sessions, because at each session the patient can observe an area of ​​hair growth failure. The areas that best respond to treatment are groin, armpit, beard and leg. The fluff, because it has very fine hairs, and the male back, because it has a thicker skin, are the areas where the results are more easily lost.

Why can the hairs come back?

There are cells called stem cells (or totipotential cells) that can produce a new fur. These cells do not die during laser hair removal because they do not have melanin, the substance responsible for the uptake of energy. Some hormonal changes - caused by pregnancy, the onset of menstruation and the use of medications - may stimulate these cells to produce new hairs.

According to the literature, a reduction of 74-84% in the long term (an average of 18 months), "explains Dr. Isabel Martinez, a member of the American Laser Academy and director of the Martinez Clinic.
