Most of us have heard about laser hair removal. Some consider it a miracle, some say it is useless, and some are afraid of the laser and its side effects! Anyway, it is a laser and you can cut stone and iron with it! If you are not familiar with lasers, think it is useless, have had an unpleasant experience before, or are among those who are afraid of the complications and dangers of lasers, this article is for you. Here, we have reviewed everything related to laser hair removal, told the facts and tried to have a useful disambiguation.
What is laser hair removal?
We don’t want to bother you with the scientific topics of laser, but it is good to have a general idea of how the laser works and how it works.
A laser is a light beam. However, the light has special physical characteristics and is very energetic. Lasers have many uses in medicine and industry. Lasers are used in industry for cutting and engraving and in medicine for various surgeries such as eye surgery (LASIK).
Laser is a science and technology. That is, depending on its application, you can include special features in it and optimize it to perform a specific task. Laser hair removal is precisely designed to remove unwanted hair without affecting other parts of the skin and body.
Different lasers are used to remove unwanted hair. Alexandrite, Nd:YAG and diode technologies are among the most used lasers for hair removal. These lasers are different in terms of application. For example, alexandrite is more effective for those with light skin and Nd:YAG is used more for dark skin. This practical difference is due to the difference in physical properties of lasers such as frequency and wavelength.
The laser affects the follicles. Laser hair removal is designed to heat the hair bulb and damage the follicles. Follicles are small organs inside the skin that produce body hair. When the hair follicle and bulb are damaged, hair growth stops forever.
The laser inflicts selective damage. The important point is that the heat of the laser causes the follicles to be damaged and disabled, but this damage is completely selective. It means that there is no damage to the skin and tissues adjacent to the follicle at the same time. Of course, sometimes the skin is damaged due to the error of the operator. We have reviewed these issues in the section on the side effects of laser hair removal.
Laser reduces unwanted hair permanently. This method can remove between 70 and 90% of unwanted hair forever. For this reason, scientifically, we say that laser causes a permanent reduction of unwanted hair and not a permanent removal of unwanted hair. Because we cannot remove 100% of unwanted hair in one treatment period. But those 70 to 90 percent that have been removed will never grow again.
Applications of laser hair removal
Laser hair removal can be used anywhere on the body. Of course, there are more referrals for laser for some parts of the body. For example, bikini and genital area lasers and facial hair lasers are more common in women. In men, armpit hair laser, beard line laser, back hair and neck hair are mostly done. However, the laser method is so flexible, fast and effective that the entire body can be lasered in less than an hour in one session.
No matter how limited or wide the treated area is (whether it is just the back of the lips or the whole body laser), to effectively remove or reduce unwanted hair, you must complete a course of treatment. This course usually includes 4 to 6 laser sessions with intervals of about 6 weeks.
Laser facial hair removal
The facial area is one of the sensitive areas of the body where we can safely remove unwanted hair with a laser. Of course, the hair under the eyebrow cannot be lasered because there is a risk of eye damage, but the hair between the two eyebrows can be effectively removed with a laser.
Considering that shaving is not recommended for women and waxing can increase the thickness and density of unwanted hair, lasering these hairs is your best choice.
compared to other methods
Laser is the best way to remove unwanted facial hair because a razor can leave permanent scars on your face and you have to shave your face every 3-4 days. Banding, waxing and removing hair with tweezers can increase excess hair by increasing blood supply to the skin. So the best way to permanently and safely remove unwanted hair is laser.
For women who have ovarian laziness
Facial hair is a major problem for women who suffer from ovarian cysts or polycystic ovary syndrome (PCOS). Facial hair becomes thick and abundant in this disease. Again, waxing, tweezers and tying are not suitable solutions because they cause extra hair to thicken and increase. Although laser hair removal is not as effective for women with ovarian laziness as for other women, it can significantly help reduce facial hair.
Number of sessions
Laser facial hair removal is very fast and may take 5 to 10 minutes, but facial hair (like hand hair) is very stubborn and requires more sessions. Usually, 6 to 12 laser sessions with 2 to 4 week intervals are needed to effectively remove facial hair.
Facial laser pain
The amount of laser pain depends more on the location and your tolerance threshold than anything else. In general, lasers on the lower areas of the face, the areas in front of the ears and behind the lips do not hurt. Forehead laser may be a little painful at first, but it will be less in the next sessions. For those who feel a lot of pain, we can use numbing creams or painkillers.
