Laser Hair Removal – Alexandrite

Laser hair removal is one of the most popular treatments in Aesthetic Medicine. it is a treatment that makes use of the latest laser technologies in order to remove the unwanted hair. Many laser devices have been developed like the Alexandrite laser focused to help people solve their unwanted hair problems.

What woman does not dream to permanently get rid from cumbersome, awkward and sometimes painful epilation process and enjoy a beautiful and smooth skin without unwanted and unsightly hair growth. And what man who suffers with excessive hair growth on the back or chest would not want to escape permanently from this picture?

Traditional methods of hair removal such as wax, razor, electrolysis needle etc., proved ineffective to truly eliminate the problem and often accompanied by undesirable side effects (folliculitis, burns, pain, etc.). The results are short term, very frequent repetitions are needed and more required by all in any case the solution offered is not permanent.

The modern hair removal treatments include laser hair removal treatment and photolysis (IPL laser hair removal). Both treatments are advanced solutions to the problem belonging to the so called “light therapy”.
To understand the mode of action of these treatments should first of all be clear that the LASER has nothing and should in no way be confused with IPL hair removal. These are two completely different treatments such as philosophy of application and results.

The treatment of unwanted hair growth using technology LASER is the most modern and comprehensive proposal for the definitive solution of the hair problem. Latest LASER systems come to offer a unique answer to the problem of persistent reduction of excessive hair growth with a safely and really low cost compared with other treatments.

But what exactly is the technology of LASERS;

LASER (Light Amplification by Stimulated Emission of Radiation) essentially means enhanced light. Light which is stable, monochromatic with a specific wavelength, visible or invisible. This monochromatic light emitted by a special mechanism which is located in the heart of each LASER system, which determines the color of the produced light.

The mechanism induced produces a light beam which is then transmitted from the controlled device through a very thin optical fiber. Depending on the characteristics of light is determined and the application of LASER. In essence that is there are many different kinds of LASER devices for hair removal. Each of them produces a different light than the others and has a different use.

What types of LASER currently exist for the treatment of unwanted hair growth?

The LASER systems available today predominantly for hair removal are:

  • Alexandrite LASER 755 nm, (Alexandritis)
    alexandrite laser
    Alexandrite laser hair removal machine
  • Diode LASER 800-810nm,
  • Nd: YAG laser 1064nm
  • Ruby LASER 694nm

Comparative study between LASERS, published in the journal of the European Dermatology Association (JEADV Jan 2006 vol 20 NoI, p.9-19), showed that LASER Alexandrite and diode LASER have a greater efficiency.
Since LASER Alexandrite has been approved by the US Food and Drug Administration (FDA approval) to permanently reduce unwanted hair growth,  we will try to do a more thorough report on the treatment of unwanted hair using this type of LASER.

How does Alexandrite laser hair removal work?

The LASER Alexandrite, through the stimulation of a crystal produces light which targets the melanin of the hair follicle cells. Melanin is a dark pigment which is produced by the melanocytes of the skin and this is due to the skin color and the color of the hair.

When light is incident on the LASER cells containing melanin, is completely absorbed by this pigment resulting cells are destroyed by the process of sublimation. Specifically therefore when light falls on the LASER dark or black hair, then absorbed by the melanin cells bristle thereby destroyed strain but particularly the hair follicles since there melanocytes have the highest concentration.

The hair follicle is essentially the matrix from which the hair is incurred and hence the destruction of the hair follicle results in gradual attenuation of the hair and gradually leads to definitively eliminate this. This phenomenon is called “selective photothermolysis” and is the basis of technology LASER depilation.

Does Alexandrite laser apply in all skin types?

The Alexandrite laser is an extremely safe choice in light skin color, since the light is not absorbed by LASER surfaces that have no melanin. In Mediterranean countries for people having the “white” skin, that type of Laser hair removal treatment by appropriate selection of the treatment parameters is a very good and efficient solution.

The LASER Alexandrite is not a good solution to  dark races in general, and in the newly tanned skin. Black skin or freshly tanned skin means a high concentration of melanin, which the application of LASER will result in the absorption of light energy by the melanocytes, with the direct consequence of burns and attendant discoloration or hyperpigmentation after the hair removal treatment.

For dark skinned race or recently tanned skin LASER choice in terms of security, although not as effective, is the Nd: YAG laser 1064nm.

Is Alexandrite LASER effective on blonde or white hair?

This type LASER has the greatest efficacy in treating hair growth including black or dark hair, anywhere on the body.
Since the philosophy behind laser treatment is based on the absorption of light by melanin, although in some area of the body are white or blond hair, i.e. hair without melanin then the application of LASER Alexandrite has no therapeutic activity.
Today there are some types of LASER that specialize exclusively in white or blond hair. In these cases are addressed to electrolysis type solutions.

What should the patient expect during the treatment?

First always wear safety glasses to protect our eyes from the light of LASER.
In each embodiment the doctor guides the light beam to the treatment areas with a small transmission system, a special head (piece hand) from which emitted LASER.
Through this head, the beam of light of LASER, is released in one area of skin and destroys many hairs simultaneously and not separately each individual hair.

Does Alexandrite laser treatment hurt?

Before and after each pulse of LASER a short pulse of cooling spray is usually released in the treatment area, through a special cooling mechanism.
Making use of the cooling system the sensation of pain truly minimized.
More sensitive areas such as the mustache, eyebrows or bikini which is theoretically more painful, are being treated using anesthetic ointment (type EMLA), so the process of hair removal is completely painless.

Women who did previously depilation needle, consider hair removal LASER virtually painless.
This is because the pain coming from LASER is small and subjective since the LASER light is selectively absorbed by the hair follicle while the pain electrolysis is large and effective because due to electric current that burns each hair separately.

Should the area be shaved before laser hair removal treatment?

In order for the beam of laser light to be effective, it should cause destruction in the bulb, the hair root, the part of the hair beneath the skin that does not appear.
Laser light does not “see” and does not need to “see” the visible part of the hair, that which emerged above the skin. It acts directly on the hair follicle in the skin, where the hair is born, leaving intact skin surface.

What the doctors usually do is simply to reduce the length of the hair to raise at 1-2 mm above the skin and not to shave the treatment area. This occurs predominantly at the first session, given that the sessions that will follow, if they become the fourth or fifth most weeks, the hair will not have a chance to out again.

How many hair removal sessions will be needed? How long do they last?

In each body hair growth there are two zones: the hormone-dependent and non-hormone-dependent zones. For example the face, mustache and loin are hormone-dependent zones. Underarms, bikini, hands, legs, nipples chest, eyebrows are not hormone-dependent zones.

The application of LASER in hormone-dependent areas, requires frequent repetitions because of standing “bombarding” performed by hormones in the hair follicles.

Specifically it may take 10 to 16 sessions with an interval of one month to achieve permanent hair reduction at a rate of 70-90% in the hormone-dependent areas while non hormone-depended areas require 6-8 sessions on a monthly basis, for the same hair growth reduction rates. Application time varies from a few minutes to a maximum of one hour, depending on the region.

How often should I repeat the Alexandrite LASER session?

In each hair distinguish during the life of three phases: anagen, telogen and Catagen. During the anagen phase lasts approximately 3-5 weeks, depending on the area of the body, the hair is regenerated and emerges from the hair follicles.

In this phase the concentration of melanocytes at the base of the hair follicle is the maximum so that the application of LASER every 4 to 5 weeks is accompanied with maximum efficiency. This is because due to the high density of melanocytes in the anagen phase, we have the maximum light absorbance of the Laser the pocket so as to cause the maximum destruction of bristles.

In essence that is the treatment should be repeated once a month or not later than 40 days. In the interval between applications, usually do not have time to grow any hair in the treated area.

Is Laser hair removal safe? Are there any side effects?

Laser hair removal using alexandrite laser offers a permanent, safe and fast solution. Because it is simply amplified monochromatic light can be applied already from early adolescence and in all areas of the body such as a mustache, chin, cheeks, eyebrows, underarms, bikini, chest, back, arms, thighs, drumsticks. This is an effective treatment that can be applied literally everywhere where unwanted hair exists.

Specifically it is safer to do LASER on underarms or bikini from shaving these areas because only a few repetitions are needed to permanently freeze the annoying hair growth. The depth of hair removal laser penetration is focused on just a few millimeters so it does not affect the remaining lymph nodes.

Regular shaving of the underarm or bikini and injuries made in the region, is more dangerous to create inflammation in the lymph nodes than the LASER light which will give a permanent and definitive result in about six to eight repetitions.

After each application the areas can display a mild redness, slight itching or a small swelling in the healed area but these effects usually last a few minutes or at most a few hours. Permanent effects such as hyper-pigmentation, discoloration are extremely rare, since most systems have effective cooling mechanisms.

Before and after the application of laser hair removal.

Before applying a laser hair removal treatment the patient should definitely avoid exposure to sunlight and to several artificial skin tanning ways like Solarium. After the treatment exposure to sunlight should also be avoided as far as possible and if this is inevitable eventually the use of sunscreen with SPF SPF 30 or higher is required.

Could someone achieve the same results with waxing or photolysis?

The photolysis machines certainly have a place in the hair removal treatment, but they are clearly more “primitive” forms of treatment in relation to the revolutionary technology of LASER.

Specifically photolysis is a form of hair removal technology is based on the phenomenon of intense pulsed light (). It differs completely from the technology of LASER light on why the photolysis is poly-chromatic. Exactly about it, because that is photolysis machines can not emit light with stable and unique color LASER, are less selective effect on hair and therefore providing much less effectiveness and unfortunately less security.

Treatments using photolysis applied extensively to non Medical Center slimming and beauty, usually aesthetic and generally non-medical data that no special license is required. The results of photolysis is quite satisfactory, since it improves the areas of unwanted hair growth, but usually without giving final and permanent solution.

Unlike photolysis, right to use LASER have only Medical Centers, eminently Plastic Surgery and Dermatology, since the application of LASER technology is not so simple and requires specific training and expertise of the medical staff.

The constant development and upgrading LASER machines in recent years offers excellent results in the treatment of unwanted hair growth “which besides the fact that it is very safe, they tend to be radically and permanently.”

Can man do laser hair removal? If yes, what are the most common application areas?

One of the main problems of men are hirsutism ie areas with hair on the back, shoulders and neck. It is in fact the presence of unwanted hair growth in conspicuous places of the trunk, which especially during the summer months covering the muscle lineage body giving it an unsightly picture many times.

Hair removal LASER Alexandrite consists a unique treatment to remove annoying hair growth for men as it may relieve them safely, permanently, quickly and relatively painlessly from unsightly hairs.
Beyond the back hair removal or waxing the shoulders and neck, often dealing with the LASER Alexandrite chest waxing and waist (lumbar) and hand waxing.

Young men who take care of their body or very often men engaged in Bodybuilding and want a perfect image of themselves except back waxing, neck, hands and chest do waxing on legs and abdomen, so as to completely delete the muscles when they descend into fights.

Laser Hair Removal Cost

It could be argued in the past, before about five to ten years, that “hair removal LASER it consists a luxury resort”. Luckily not the case today.

Hair removal using the LASER Alexandrite is a completely safe, fast and effective treatment with extremely affordable cost.

Since they have discovered new, faster and more efficiently LASER and given the current economic conditions we can say that today the cost of hair removal treatments with LASER is very low.

Beyond the permanence of the results offered by the technology of LASERS, this is an additional reason why LASER hair removal is considered one of the most popular treatments at the Clinics of Plastic Surgery.

Indicative we can list the cost of some hair removal treatments with Alexandrite LASER:

Upper lip – chin – eyebrows: from 30-60 Euro (40-80 USD)
Cheeks (sideburns): from 30-50 Euro               (40-66 USD)
All face-neck (Full Face): from 70-100 Euro    (83-120 USD)
Armpits: from 70-90 Euro                                   (83-106 USD)
Bikini (line): from 70-80 Euro                            (83-94 USD)
Bikini (all front): from 90-100 Euro                  (106-120 USD)
