Laser hair removal
Treatment in our office
Diode laser at a 808nm wavelength is the best new hair removal technology. It is considered as a “calm strength” and it is aimed both at men and women who want to reduce or permanently eliminate hair growth on the face, armpits, back, pubic area, as well as on the buttocks, legs, chest area and, if needed, the abdomen.
Diode laser hair removal is completely pain-free and, as such, is performed without applying anesthetic cream. It is also extremely effective, as results can be achieved in just 3 – 5 sessions in 40-day intervals.
Another great advantage of diode laser is that the patient can use a depilatory cream or a razor prior to each session because, in contrast to conventional laser treatments, hair doesn’t need to be grown beforehand.
How diode laser works
The main principle of hair removal is selective photothermolysis, during which a specific wavelength acts for a specific amount of time on the targeted hair follicle, leaving the surrounding tissues intact. Essentially, a laser is effective when the laser beam contains the appropriate amount of energy and each pulse lasts long enough to affect the hair follicle, causing its destruction.
Diode laser operates at a 808nm wavelength and the energy – pulse duration is adjusted according to the area under treatment and the skin complexion. The laser head spot is automatically cooled and, in combination with the gel applied and the ultrasounds, the treatment is quick and pain-free.
As laser technology has greatly improved in the past years, laser is considered the best method of hair removal, as the application of local anesthetic cream is unnecessary and the desired result is achieved after 3 – 5 sessions every 40 days, with a great chance that further treatments will not be needed, Why so? All hair removal lasers act only on the follicle of actively growing hair, namely hair that is in the anagen phase. It would, therefore, be of no use to have more frequent sessions, as it is only logical that targeting all follicles in one session is not possible.
Carbon dioxide (CO2) laser
Resurfacing carbon dioxide (CO2) lasers have the ability to separate covalent bonds. They are, thus, used to treat liver spots, actinic keratosis, milia and hypertrophic adenomas on the face, as well as cherry angiomas (red moles). This type of laser can be used on the pubic area to treat genital warts, but it can also be applied on persistent warts on any place on the body. The CO2 laser removes the diseased tissue by evaporation, creating small wounds in the process, which usually heal in 2 weeks time.
Fractional CO2 lasers are mainly used for treating wrinkles, pigmented skin lesions from sun exposure, acne scars and stretch marks. By heating the dermis, fibroblasts are stimulated and create new collagen and elastin, increasing skin thickness. This is extremely beneficial for the skin, because it regains its health and glow, making it appear alabaster.
Increased safety profile
Fractional laser thermolysis (Fractional CO2 lasers) acts by depositing tens or hundreds of microscopic laser beams on a per cm2 area of skin at a time, leaving the skin between the beams healthy. This enables faster healing and minimizes the risk of scar formation and hyperpigmentation; that is why this type of laser therapy has a better safety profile than other similar lasers.
After the Treatment
It should be noted that, because fractional CO2 laser is performed from October until May, sun protection and constant moisturizing are quite important. After the treatment, there is usually some redness that subsides after 2 – 4 days and patients can apply makeup if they want to.
Q–switched Nd–Yag laser
Nd-YAG laser has a wavelength of 1064 nm and can reach deeper layers of skin tissue than other laser types.
In Q-switched mode, Nd-Yag produces beams at 2 wavelengths, one beam in the infrared spectrum (1064 nm) and a second beam (532 nm), which is useful for superficial skin lesions. Q-switched lasers operate on very brief pulses with high-intensity energy.
Due to long-term sun exposure and as years pass, dark spots may start appearing on the skin. Patients usually worry about these spots, since they do not know if they are benign or not.
With the help of the dermoscope, the dermatologist will detect which lesions can be treated with the Q-switched laser. Red and brown lesions respond better on the 532 nm wavelength. By some blasts on the lesion, it sublimes, leaving a thin crust in its place, which will later go away.
This is a skin-friendly and quite effective treatment of hyperpigmentary lesions. The pigment is soon secreted from the system, which is completely safe throughout this procedure. After a short amount of time, during which patients have some scratch-like marks, the new, healthy skin is revealed without the unappealing hyperpigmentation.
Blue, gray and black coloured ink used in tattoos can be removed with a Q-switched Nd: Yag laser (at a 1064 nm wavelength). It is important to know that the colour of the tattoo and the depth of the pigment in the skin affect the duration and the result of the laser treatment.
The laser treatment includes the selective decomposition of ink molecules, which are then absorbed by the macrophages and secreted from the body.
Multiple sessions (usually 5 or more) in a minimum of 7-week intervals might be needed to achieve the desirable results.
The removal of eyebrow tattoos is usually accomplished in fewer sessions.
ClearLift laser “face lift”
This is a new skin regeneration and anti-aging method, which has zero recovery time and is ideal for all ages and skin types. A carbon cream is applied and is then neutralized with constant blasts, resulting in the activation of fibroblasts by the laser, since at a 1064 nm wavelength the laser penetrates the dermis without burning the upper skin layers.
This method, also known as “black doll”, is becoming more and more popular and it is ideal as a maintenance treatment after 2 – 3 fractional laser sessions, especially on more “sun-aged” patients.
It should be noted that:
Throughout the treatment, patients must protect their eyes either with a non-transparent cover or with the special glasses.
Local anaesthesia might be applied on the area, but it is usually not necessary.
Care should be taken during the first days after the treatment, so as to avoid friction in the area by any means and also by applying smoothing skin cleansers.
Over the course of the treatment, patients should protect the skin area under treatment from sun exposure, in order to minimize the risk of post-inflammatory hyperpigmentation.
