Reading Time: <1 minuteIt is recommended that hair removal be performed at a medical institution. Laser hair removal has now evolved to the point where it is possible to choose a laser hair removal method that suits various areas, skin color, hair thickness, growth pattern, and quality. The main hair removal lasers are Alexandrite, diode, and YAG lasers, but hair removal devices that can emit a combination of these have also been developed. Some medical institutions specializing in hair removal have multiple hair removal devices and can respond to patients' needs. I have supervised the medical hair removal theory. https://lenard.jp/magazine/medical-epilation-ranking/   For cosmetic surgery, cosmetic surgery, armpit treatment, hyperhidrosis treatment, petite plastic surgery, hokuro removal, scar treatment, wrinkle, and sagging treatment in Nagoya, please contact Sakae Clinic.

Reading Time: <1 minuteDifference between medical hair removal and salon hair removal in beauty treatment salon So I looked for materials and papers on the most important aspect of the light used. Laser hair removal is mainstream in medical hair removal, but IPL hair removal is mainstream in beauty salons. This is because laser hair removal equipment cannot be used in beauty salons. Also, high-energy hair removal equipment like in medical institutions cannot be used. For both IPL and lasers, understanding the light absorption curve is the most important thing. This is very important in understanding the basics of hair removal theory, such as the characteristics of light. I have been doing IPL hair removal for many years, and if you have a solid understanding of the theory and characteristics of IPL hair removal, IPL hair removal is still effective in some areas. 1:https://onlinelibrary.wiley.com/doi/epdf/10.1002/lsm.20877 2:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3390232/ 3: https://link.springer.com/article/10.1007/s10103-004-0298-6   Laser systems such as the ruby ​​laser (694 nm), alexandrite laser (755 nm), diode laser (810 nm) and neodymium: yttrium-aluminium-garnet (Nd: YAG) laser (1,064 nm) are commonly used in hair removal. However, permanent hair removal has been difficult to achieve using lasers owing to the long growth / rest cycle of normal human hair follicles. There is still an increasing demand for safer and more efficient hair removal techniques. The latest and most effective choice in the treatment of hair removal is non-coherent intense pulsed light (IPL), which is both efficient and safe for hair removal. A group of 210 patients with skin type III–V were treated for superfluous hair in There was a significant hair reduction of about 6% with no side effects and minimal complications. Follow- up was done 80 months after the last session. In conclusion, IPL is very effective and safe for hair removal. 4: https://www.researchgate.net/profile/Andrea-Willey/publication/6371010_Hair_stimulation_following_laser_and_intense_pulsed_light_photo-epilation_Review_of_543_cases_and_ways_to_manage_it/links/5ea31e7345851553faaac989/Hair-stimulation-following-laser-and-intense-pulsed-light-photo-epilation-Review-of-543-cases-and-ways-to-manage-it.pdf   XNUMX:http://www.medicalphotonics.jp/pdf/mp0010/0010_018.pdf XNUMX:https://www.jstage.jst.go.jp/article/jslsm/31/1/31_1_53/_pdf/-char/ja XNUMX:https://ci.nii.ac.jp/naid/10029410625 XNUMX:https://ci.nii.ac.jp/naid/10029410618/   For cosmetic surgery, cosmetic surgery, armpit treatment, hyperhidrosis treatment, petite plastic surgery, hokuro removal, scar treatment, wrinkle, and sagging treatment in Nagoya, please contact Sakae Clinic.

Reading Time: <1 minuteRecently, I have been asked to supervise hair removal websites and check the medical suitability of articles. There seem to be very few medical institutions where doctors themselves perform hair removal with a solid understanding of hair removal theory. Nurses seem to be in charge of hair removal treatments at almost all medical institutions, but I wonder if they actually read papers and understand hair removal theory before applying it clinically. The target when removing hair is the melanin pigment of the "hair". Oxidized hemoglobin is the color of blood, that is, the color of the red blood cells in the capillaries in the dermis. The shorter the wavelength of laser light, which is easily absorbed by melanin and easily raises the temperature of melanin, the better, but in reality, if it is 400 nm, for example, it will just be absorbed by the melanin in the epidermis and the light will not reach the hair papilla or bulge area, and it will only cause epidermal burns. Also, if you want to destroy only melanin without burning blood vessels, you might think that a wavelength of 694 nm (ruby laser) would be good, but in reality, the shorter the wavelength, the more light is scattered, and with ruby's 15 nm, only 750% of the light reaches the dermis. For this reason, the wavelength suitable for destroying melanin in hair and hair roots with medical hair removal lasers is around 790-755nm, so 515nm Alexandrite light is suitable for medical hair removal lasers. In the case of beauty salons, hair removal is performed using IPL light containing various wavelengths starting from 1200nm. This is because only doctors are permitted to use lasers under the Medical Practitioners Act. For hair removal, IPL is used in beauty salons, so the wavelength is limited (IPL with a wavelength of 1-2nm was used for medical hair removal). *Factors that affect hair removal effect 10: Wavelength 30: Pulse width XNUMX: Fluence XNUMX: Number of irradiations XNUMX: Number of hair removals *Situation on the client's side XNUMX: Thickness of hair to be removed XNUMX: Color of hair to be removed XNUMX: Hair density XNUMX: Hair removal area XNUMX: Skin color These factors are taken into consideration when performing hair removal. Theoretically, the IPL spectrum is almost complete, and the only way to develop hair removal devices is to combine it with high frequency, increase the cooling power, and increase the fluence, as long as there are no problems under the Medical Practitioners Act and the Pharmaceutical and Medical Device Act. It is important that heat is transferred firmly to the bulge area and hair papilla to cause tissue destruction. Unlike lasers, IPL has the disadvantage that it is difficult to transfer energy only to shallow areas due to a lot of diffusion. Increasing the fluence unnecessarily can easily cause epidermal burns, so care must be taken when hair removal is performed on sunburned or dark-skinned clients. Unlike lasers, IPL is a pulsed light with the characteristics of incoherence, multi-wavelength, and scattering. It generally uses a xenon lamp as a light source, and uses wavelengths from XNUMX to XNUMX nm by cutting the short wavelength region with a filter. Depending on the application, one or two more filters are added to limit the wavelength band to be used in actual treatment. The energy intensity is not uniform, but has a peak on the short wavelength side of the oscillation wavelength band. In IPL treatment, pulsed light oscillated in milliseconds is irradiated onto the skin surface through a sapphire irradiation filter. The spot size is often a large rectangle of about XNUMX x XNUMX mm, allowing for wide-area treatment in a short time. IPL devices vary greatly in settings and performance, including the oscillation wavelength band, settable pulse width (e.g., a few milliseconds to tens of milliseconds), pulse division method (e.g., single, double, triple), uniformity of output within the pulse, and the presence or absence of a cooling device for the skin irradiation surface and the type of cooling device used.            

Reading Time: <1 minuteI am currently consulting on the theory of hair removal device development at the request of a certain manufacturer. It seems that most people do not understand the difference between hair removal at beauty salons and medical hair removal. Hair removal using lasers is not permitted at beauty salons. In the past, IPL, a type of light hair removal, was used for medical hair removal, but now laser hair removal is the mainstream. Hair removal devices that combine IPL with RF energy have been used in clinical practice for many years and I still prefer to use them. Hair removal devices have been developed on a theoretical basis. The aim is to achieve long-term hair removal effects by destroying the so-called hair center. The center of hair was once called the hair papilla, but it has now become clear that stem cells in the bulge region play a very important role in hair growth and hair development. In other words, hair removal effects cannot be achieved unless the bulge region is thoroughly destroyed with thermal energy. I have summarized the knowledge and papers on the bulge region. bulge area The bulge area is a newly discovered organ in recent research. It sends commands to the hair papilla, which produces hair, and promotes hair growth. The new theory behind medical laser hair removal is that by destroying this bulge area and cutting off the command for hair growth, permanent hair removal can be achieved without destroying the hair matrix cells or hair papilla, which are the seeds of hair. Until now, hair matrix cells (hair roots) have been destroyed, resulting in permanent hair removal.Medical laser hair removalIt was said to have the effect ofHowever, recent research has revealed that it is also important to destroy the bulge region, a hair growth factor that nourishes hair matrix cells.What is the bulge region?alopecia treatmentIt is a type of stem cell (cell that produces cells) that was discovered in 2000-2001 as part of research into hair growth, and produces cells that are important for hair production. Hair growth factors produced in the bulge area become hair matrix cells, which receive nutrients from the hair papilla to produce hair.Medical laser hair removalBecause the aim was to destroy the hair matrix cells, the bulge area was also destroyed at the same time.However, in recent years, hair removal machines that destroy only the bulge area have also appeared.destroy hair matrix cellsMedical laser hair removalThe heat was destroying the dermal papilla through the black hair.Since hair in the growing stage is connected to the dermal papilla, it was possible to thermally destroy the dermal papilla if there was black hair.However, the bulge area is not connected to the hair and always exists in the dermis.In other words, whether or not there are hairs is theoretically irrelevant to destroying the bulge area.However, the mechanism of the currently used hair removal machines that target the bulge area remains the same: they react to the black melanin pigment and apply heat.Therefore, even if the method destroys the bulge area, hair removal is performed in accordance with the hair replacement cycle.   Bulge region related papers 1:https://www.kitasato-u.ac.jp/ktms/kaishi/pdf/KI44-1/KI44-1p001-005.pdf 2:https://www.jstage.jst.go.jp/article/manms/16/3/16_130/_pdf/-char/ja 3:https://www.jstage.jst.go.jp/article/koshohin/42/2/42_420203/_pdf/-char/ja 4:https://www.jstage.jst.go.jp/article/dds/24/2/24_2_109/_pdf/-char/ja XNUMX:https://www.jstage.jst.go.jp/article/jnms/69/6/69_6_564/_pdf/-char/ja XNUMX:https://www.jstage.jst.go.jp/article/jslsm/27/4/27_4_280/_pdf/-char/ja 1: file:///C:/Users/NOBUHI~1204/AppData/Local/Temp/XNUMXA_Abstract.pdf XNUMX:https://www.kose-cosmetology.or.jp/research_report/archives/2016/fullVersion/Cosmetology XNUMX:https://www.tandfonline.com/doi/abs/10.1080/14628839950517039 XNUMX:https://onlinelibrary.wiley.com/doi/abs/10.1111/bjd.12477 XNUMX:https://www.taylorfrancis.com/chapters/edit/10.1201/9781003068952-5/hair-follicle-stem-cells-robert-lavker-tung-tien-sun-john-sundberg   For cosmetic surgery, cosmetic surgery, armpit treatment, hyperhidrosis treatment, petite plastic surgery, hokuro removal, scar treatment, wrinkle, and sagging treatment in Nagoya, please contact Sakae Clinic.
