The concept of laser was developed in 1917 by Albert Enstein as part of the quantum theory. Enstein has proposed the principles and concepts required to install a functional laser system. However, ruby laser was developed for the production of functional lasers for many years and the first laser device was developed in 1960.
Laser method was used for military or industrial purposes at first. For medical applications, laser systems could be produced much later. Laser devices that can make short pulses one by one have been developed over the years. The medical development process of lasers started from 1983.
New lasers have been produced in areas such as capillary treatment, stain, tattoo removal. Medical and clinical studies accelerated at this stage. The first type of light-based epilation began to be used in 1994. Laser epilation applications were actively approved in the late 1990s and entered the clinic. Laser hair removal has been an application approved by the FDA in 1998.
The purpose of laser epilation is to disrupt the function of stem cells that produce hair. The sudden high heat energy created by the absorption of the laser beam by the black dye in the structure of the hair, called melanin, damages the stem cells that produce the hair. While black hairs, that is, hairs that contain melanin substance more are affected by epilation, the effectiveness of gray and white hairs is almost low.
Unwanted hair on the body is an aesthetic problem for both men and women. Excessive hairiness; It can be caused by hereditary, hormonal or various medications used. Permanent solution cannot be obtained in the net, which is used today to get rid of unwanted hair, with razors, ropes, tweezers and chemical hair removal.
The principle of laser hair removal is to ensure that the color substance called melanin, which is located in the hair follicle, is retained by the laser light and converted into heat, then destroying the hair follicle with this resulting heat energy.
Laser Epilation Types
Laser types used for epilation are 3 types. It is important to start laser epilation with the correct laser type. Before the application, the specialist doctors should decide which laser method is suitable for the person by evaluating the skin and hair structure. With this evaluation, the success rate expected from epilation increases and the possibility of side effects decreases.
Diode Laser Hair Removal
“Diode laser” is a laser treatment management that aims to reduce unwanted hair. Since the wavelength of Diode laser is longer than other laser methods, effective results varying according to the treatment time are obtained even in dark colored skin.
Diode laser has a wavelength of 810 nm. This wavelength goes deeper in the skin than Alexandrite laser. Coming deep into the skin is more effective in areas with deep hair. Diode laser can be applied comfortably even on dark skin as its wavelength is long.
Alexandrite Laser Hair Removal
Alexandrite laser, which is a practical and effective method, can only be used on open skin types due to its technical features. The immediate removal of the hair from the surface after the treatment increases the satisfaction after the application.
Application with this laser increases the possibility of side effects in people with dark skin. Using the Alexandrite laser in areas such as the face and neck may cause an increase in thin hair. Its use in these regions is not recommended even if the skin type is light color.
Alexandrite laser is well held by melanin. Therefore, it can only be used on open skin types. This laser system works very well for correctly chosen people. However, in risky areas such as the face, it can cause hair growth instead of hair reduction. The back, shoulder and arm areas are among the regions where the effectiveness of this laser is low.
Nd Yag Laser Hair Removal
It is a system developed for very dark skin types. It is very painful and restricts the usage area of this laser compared to the other two lasers. It is a rarely used laser in very carefully selected situations.
Diode, Alexandrite and Nd yag lasers are laser systems used for epilation. Each of them can be preferred in different situations, namely the skin color of the person, the type of hair, the region to be applied. There is no such thing as the best laser system. All-in-one use is suitable for good results.
The laser epilation application procedure begins with the evaluation of specialists by examining the area to be applied by hair and skin type. As a result of the examination, the convenience of laser epilation, possible results and side effects are transferred to the person.
Then the application process is started. It is very important to choose the appropriate laser type in laser epilation application. For this reason, the following three epilation devices should be available in a laser clinic. These devices are named according to the wavelengths of light in nm. These:
- Diode Laser Hair Removal
- Alexandrite Laser Hair Removal
- Nd: Yag Laser Hair Removal
After the appropriate laser epilation device and dose is determined, laser epilation process is started.
What does the success of the laser epilation process depend on?
The first step to successful laser hair removal application is to choose the right device.
Skin Color (NO RACİSM)
The skin color of the person to be applied provides an advantage in application. Because dose increase can be made more easily in open skin types. The higher the laser dose, the greater the success.
In laser hair removal applications, the effectiveness of the thick hair is high. For this reason, the darker the hair, the more successful the laser epilation. In thin hairs, the effectiveness is very little or not at all. Diode lasers can provide efficiency in some well-chosen fine hairs.
Epilation application area: One of the hardest areas in epilation is the face area. Diode lasers are the ideal choice for the face area. Alexandrite laser should not be preferred in the face area. The armpit, genital and lower leg areas are the best response to laser epilation.
Gender (Respect For Women)
Women are more advantageous for laser hair removal. The average success of men is lower than that of women. If women have hormonal hairiness, the disease must be treated.
What should be considered before laser epilation?
Epilators, tweezers, rope removal should not be done on the hair that takes the hair from the root until at least one month before the laser epilation. In order for laser epilation to work, it has to extend to the root of the hair.
There should be no tanning or entering the solarium until 1–1, 5 months before laser epilation. Drugs used before laser epilation and all known diseases, especially skin diseases, should be reported to the doctor. In addition, if acne treatment has been observed in the last 6 months, the doctor should be informed.
What Preparations Are Made For Laser Epilation?
Before the laser epilation process, the area is cleaned from deodorant and other cosmetics with a wet wipe. The hair in the area is shortened with a shaver. In order to prevent loss of time in the sessions after the first session, the person can perform the shortening process 3 days in advance. The pain is usually minimal in the laser epilation session. However, local anesthetic cream can be applied 1 hour before the procedure in people who have a lot of pain.
How is Laser Epilation Application Made?
he laser rays produced in the laser device are applied to the skin with a hand tool. An area of 15 mm in diameter is scanned with one shot at a time. People who do and have laser epilation procedure should wear safety glasses during the procedure.
The rays applied to the skin are held by the dye substance called melanin, which is in the structure of the hair and gives black color. The retained light energy turns into heat energy in the hair. The heat transmitted to the hair root destroys the hair root in a millisecond time. At this moment, a feeling like a slight needle sting is felt, swelling and redness are observed in the hair roots.
These symptoms indicate that the hair is affected. Thanks to the air and contact cooling provided through the device, the skin is protected and pain and side effects are reduced. Even during cooling, it is observed that redness and edema have passed.
After Laser Hair Removal
After laser epilation, cooling the area with ice application or air at intervals of 15-20 minutes relaxes the skin, reduces redness and swelling or loses completely.
Moisturizing the area with moisturizers after the procedure also helps the skin to recover.
The first 24 hours after laser epilation, the application area should not come in contact with very hot water.
Heavy sports, sweating should not be performed on the area where epilation is applied.
It should not be sunbathed and entered into a solarium for tanning for 15 days after the application. If laser epilation has been applied to exposed areas of the skin such as the face, sunscreen should be used in sunny weather until the next session.
How many sessions is laser epilation applied?
Performing an average of 6 sessions of laser epilation provides a successful result. The average number of sessions is 10 on facial and hormonal hairs. The session intervals are on average 2 months in the body parts and 1 month on the face.
Laser Epilation Application Areas
Armpit Laser Hair Removal
For traditional and hygienic reasons, armpit hair is generally undesirable. For this reason, armpit laser hair removal applications are frequently preferred by women.
Armpit laser hair removal applications give successful results due to the features of the region. Although an average of 6 sessions are applied, successful results can be obtained even in 4 sessions under the armpit.
When it comes to laser epilation for the armpit hair, the issue of whether the laser does any damage to the lymph nodes is often of concern. However, laser epilation does not show any harm in the glands in this area.
In laser epilation application, the laser does not go under the skin. The application takes place in the top layer of the skin. The armpit lymph nodes are embedded in the subcutaneous oily tissue. Therefore, it does not cause any harm.
Before applying the armpit laser epilation, the hairs are shortened. Perfumes and deodorants in the area are cleaned with a wet wipe. Then laser operation is started. Alexandrite and diode lasers are mostly used in armpit laser hair removal.
Armpit hair turns are also treated with laser epilation method. Since the hairs are permanently destroyed, ingrown formation after laser epilation is not observed.
Genital Area Laser Hair Removal
Epilation in the genital area is generally not preferred for traditional reasons or personal preferences. However, it is difficult and painful to apply classical methods such as waxing to this area.
Shaving can be difficult due to the folds of the genital area. Those who prefer permanent hair removal have preferred laser hair removal in recent years.
Laser hair removal applications give good results in the genital area. An average of 6 sessions is sufficient. Sometimes, satisfactory results can be achieved even in 4 sessions.
While the upper parts respond very well in the genital area, the lip parts called labium respond less. In laser epilation applications, the effect of the laser is limited to the skin. For this reason, since the effect of the laser does not go under the skin, there is no harm to the internal organs, uterus and ovaries in the region.
Laser hair removal is also a good treatment method for hair growth observed in the genital area. Rotation of the hair occurs after the reverse growth of the hair. Reverse growing hair can cause pimples or even abscesses. Laser hair removal applications are the best method for long-term treatment of hair rotation as it permanently removes hair in this area.
Laser Epilation in Bikini Area
Laser applications of the bikini area are epilation applications that are well received as in the genital area. Hairs overflowing from the bikini area mostly disturb women.
Even women who do not want epilation in the genital area prefer hair removal in the bikini area in terms of cosmetics. 6 sessions of laser epilation is generally sufficient for the bikini area.
Leg Laser Hair Removal
Hairiness in the leg area is generally not hormonal but genetic. Especially women who complain about leg hair often have hairiness in their mothers. Laser epilation gives effective results in the leg area, especially in the lower leg.
Laser epilation application has created a tendency to give up waxing and epilator-like applications in the leg area in recent years. It can be applied easily and quickly in large areas such as legs. Despite the methods that take hours in the leg area such as needle epilation, it takes 1 session of laser epilation application, 1–1 for 5 legs, as short as 5 hours.
Laser epilation is also a good option in the treatment of wrecks on the legs, especially in the sitting area and hips. Laser hair removal application removes the problem of ingrown by permanently removing hair.
Laser epilation is generally applied for 6 sessions in the leg area. The most used lasers in this region are Alexandrite and Diode lasers.
Facial Laser Hair Removal
The facial area is one of the most critical areas for laser hair removal. Particular attention should be paid to some issues in epilation applications in this region. The reason for hair growth in the face area is mostly hormonal. The cause of the disease must be determined in hormonal hairs. It is important to start hormonal therapy with laser epilation application.
Due to the hormonal sensitivity of the face area and the fast hair cycle, selective treatment should be used when choosing the laser type. Alexandrite lasers can cause an increase instead of a decrease in hair in this area.
For this reason, it is not recommended to use Alexandrite laser in this region even if the skin color is light. The laser system, which draws attention with its good results in the face area, is Diode laser. Face, neck and nape are the areas where Diode lasers are used most.
Back Laser Hair Removal
Excessive hairiness in the back area is undesirable in men. Hair turns is another problem with heavy back hair growth. Classical methods in hair growth in this region are both very painful and a second person is required for application. Laser hair removal applications have provided considerable convenience for people with such dense back hair.
Back hairs are deeply located and thick hairs. For this reason, the laser type to be selected should go deep. Only in this way can the hair root be reached. At the same time, the thick hairs, called melanin, are excessive. The laser should also be kept well by melanin. Therefore, the most effective lasers in the back hair are Diode lasers. Alexandrite lasers cannot reach enough depth in this region and their effectiveness is weak.
Chest Laser Hair Removal
The chest area also has features close to those of the back region. Situations with dense hair in this area disturb the person or his partner. In this region, men mostly want the hair to be diluted.
This is made possible by laser epilation. Diode lasers are the most preferred laser epilation devices in this region. Alexandrite lasers can also be preferred if the person is light-skinned and suffers more than Diode laser application.
Arm Laser Hair Removal
Both men and women prefer laser epilation applications in the arm area. Arm feathers are different in nature. There are generally fine hairs. Considering that Alexandrite lasers can increase thin hairs, Diode laser should be preferred in the arm and shoulder region.
Laser epilation applications may not be performed on the arms as it is exposed to the sun in summer. For this reason, winter months are generally preferred for application. Laser application in the arm area takes up to 10 sessions.
Mustache Laser Hair Removal
Hairs in the mustache area are among the most disturbing women. Since the hairiness in this region symbolizes the masculine structure, women do not want even fine hairs in this region. Diode lasers, which are mostly preferred, are used in the face area and in the mustache area.
The photoepilation method, which has a weak effect in other regions, can also provide effective results in well-selected light-skinned people in the mustache area. In this region, the application takes up to 10 sessions.
Chin Laser Hair Removal
Chin hairs are generally hormonal in origin, like all hairs on the face. Among the underlying hormonal problems are mostly polycystic ovarian disease. For this reason, the assessment of a gynecologist is appropriate.
Epilation with a few hairs on the chin can also be applied. Diode laser is most preferred if there is widespread hair on the chin. In this region, the application takes up to 10 sessions.
Nape Laser Hair Removal
Hair growth from the nape area to the back is undesirable by some men for both hygienic and cosmetic reasons. Hairiness may also be observed in women in this region. These hairs are generally thin and laser is not a solution. Diode lasers are the first choice for hair growth in the nape region of men. Laser epilation is applied for up to 10 sessions in the nape area.
Laser Hair Removal On Beard
Today, excessive hair growth on the cheeks is also not preferred among men. Men want a more elegant beard look with a straight beard line. Therefore, laser hair removal preference in the cheek area is a very preferred hair removal area for men.
Laser epilation is applied on average in the beard area for 10 sessions. Diode laser is preferred in laser hair removal applications on the beard area.
Neck Laser Hair Removal
The neck area is the shaving zone in men. In this region, frequent hair turns and pimples occur. During shaving, these pimples or hair turns cut and cause bleeding. Also, men sometimes want the beard line to be moved upwards. Laser epilation is a good option for all these situations. Hair turns disappear over time after laser.
