Laser hair removal involves the use of a high power laser to attack the roots of the hair, destroying hair follicles and vesicles so that the hair can no longer grow. Almost anyone can get laser hair removal, but it is most effective on people with light skin and dark hair. Because the laser of the laser hair removal machine is designed to release energy at the site with melanin.
This process usually requires first sedation of the skin and anesthetic application.The skin in the target hair removal area is then operated by a professional laser technician.
If you are wanting a long-term hair removal effect. Laser hair removal is a great choice. Some people gain permanent hair removal after several treatments, while most people will last for months to years. If you want to save time, laser hair removal is a quick and easy way.Laser hair removal is safe and occurs without any long-term damage to the skin.Even skin-sensitive people can use this method.You can do laser hair removal in any part of your body including full bikini area.
As for the pain, the laser hair removal is not as painful as waxing, but an anesthetic is recommended ( not necessary), it is important that the machine must be operated by professionals. Laser hair removal is much more expensive than one waxing. But as a long-term hair removal method, it is actually more cost-effective over time.
Laser hair removal is based on the selective principle of photothermal dynamics, through reasonable adjustment of laser wavelength, energy, pulse width, laser can reach through the skin surface root hair follicle, light can be absorbed and converted into damaged hair follicle tissue heat energy, making hair lose regeneration ability, at the same time do not damage the surrounding tissue, pain is slight. Laser hair removal takes advantage of the "selective photothermal effect" of the laser, with a laser mediated through the specific wavelength through the epidermis, directly illuminating the hair follicles. Melanin of hair follicles and hair stems selectively absorb light energy, and the resulting thermal effect makes it necrotic the hair follicle, and the hair no longer grows. Effect of laser hair removal Due to the irreversible process of hair follicle heat removal and necrosis, the laser hair removal can achieve the hair removal effect of permanent hair removal. If you have dark skin or uneven skin tone problems, the energy partly affects the skin, in this way, the skin rejuvenation effect after a treatment may be more obvious than the hair removal effect.
Laser hair removal techniques have been certified to achieve permanent removal of growing hair after several treatments, and the specific number of treatments is related to the skin and type of hair.Laser hair removal generally takes three to five times, some people even more times, because there are three stages of hair growth cycle: growth period, regression period, rest period, only hair in the growth period can be effectively removed.These three growth cycles of hair exist at the same time, so to achieve a more complete hair removal has to undergo several treatment.
Intense Pulsed Light
IPL technology —— also known as strong pulse light technology —— is not actually a laser treatment, using a wide spectrum of light with multiple wavelengths compared to laser hair removal. This means it has more unfocused energy around the hair and skin. So, the IPL uses a multispectral light, while the laser uses a single spectral light, which means that the IPL energy is scattered and much weaker. So the hair removal effect of IPL is weaker than the laser hair removal, but it also brings the advantage of IPL hair removal technology —— it is almost painless. Like laser hair removal, this method is also better suitable for people with light skin color and dark hair color.
IPL also used by cosmetic and medical practitioners to perform various skin treatments for aesthetic, including photorejuvenation (e.g. the treatment of skin pigmentation, sun damage, and thread veins) as well as to alleviate dermatologic diseases such as acne. There are many names and devices for pulsed light treatments such as E-Light, ELOS, and M-Light.
In general, the IPL hair remover is equipped with filters of different wavelengths, so that the machine can be used not only for hair removal, but also for skin rejuvenation.
808nm laser removal
The 808nm laser is a new generation of lasers used for hair removal.The absorption of melanin in this band is better and maximizes laser absorption of hemoglobin or water.And the penetration of other lasers, can effectively destroy hair regeneration tissue.808nm semiconductor laser is selected by more and more people for its advantages of simple structure, good curative effect and small side effects.
Compared to the IPL, the 808nm laser hair removal machine has only one wavelength laser, but the energy of this 808nm laser can reach the subcutaneous tissue of the skin, and the hair removal effect is much better than the IPL's.
The hair follicles and sweat glands are two separate tissues, hair grows from the hair follicle, while the sweat glands are next to it. The laser acts only on the melanin in the hair follicle, while the sweat glands do not absorb the laser capacity and damage the sweat glands. The laser destroys the hair follicles, so that the hair no longer grows, but does not destroy the sweat glands, and has no other adverse effects on the human body. So laser hair removal doesn't affect perspiration.
Laser hair removal is a less painful hair removal method in all hair removal methods.The results of multiple clinical trials show that most patients just feel like being "bounced by rubber bands".
Rest assured that it is still safe if the operator is skilled. It really needs a painless feeling, now the technology has reached the level of no pain, in addition, because everyone's physical condition is different, the feeling of pain is different.Before laser hair removal, there is a "an irradiation trial" phase to determine the patient's pain.
Laser hair removal machines have been certified by international authorities and received tens of thousands of successful treatments worldwide. Laser energy is selectively absorbed by melanin in the hair follicle, converted into thermal damage without damage to the surrounding skin. Human skin is a relatively light structure, plastic beauty experts clinical experiments found that in front of a powerful laser, the skin is a transparent cellophane, so the laser can very smoothly through the skin deep hair follicle, because the hair follicle has a lot of melanin, so can preferentially absorb a lot of laser energy and eventually converted into heat energy, make the hair follicle temperature rise, achieve the purpose of destroying hair follicle function.In this process, because the skin relatively does not absorb laser energy, or absorbs a very small amount of laser energy, so the skin itself will not have any damage.
Laser hair removal is suitable for dark and light hair in all parts of the body (upper and lower limbs, calves, chest, abdomen, hairline, facial beard, outside the bikini line), but not for white hair.
Those who fail or fail with electric needles, drugs, tweezers, or other instruments can try laser hair removal.
If the skin is sunburned, damaged, or the roots are red, swollen, or itchy, it is recommended not to shed hair. At this time, hair removal will cause hair follicle damage and infection.
In addition, hair removal should be avoided after waking up in the morning, during menstruation, and during pregnancy and breastfeeding. Patients suffering from diabetes, skin diseases, varicose veins or other serious diseases are not suitable for hair removal.
