Medical hair removal

Reading Time: <1 minuteIt is recommended that hair removal be performed at a medical institution. Nowadays, laser hair removal has evolved and it is now possible to choose laser hair removal according to various areas, skin color, hair thickness, growth style, quality, etc. Alexandrite, diode, and YAG lasers are the main hair removal lasers, but hair removal devices that can combine these lasers have also been developed. Some medical institutions specializing in hair removal have multiple hair removal devices and can respond to the needs of their patients. I supervised 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.

Difference between medical hair removal and salon hair removal

Reading Time: <1 minuteDifference between medical hair removal and salon hair removal in beauty treatment salon I searched for materials and papers related to the most important light used in.Laser hair removal is the mainstream for medical hair removal, but IPL hair removal is the mainstream for beauty treatment salons.This is because laser hair removal equipment cannot be used in esthetic salons.Also, you cannot use high-energy hair removal equipment like medical institutions. Understanding the light absorption curve is of paramount importance for both IPLs and lasers.It is very important to understand the basics such as the characteristics of light in hair loss theory.I have been doing IPL hair removal for many years, but if you understand the theory and characteristics of IPL hair removal, IPL hair removal is still effective depending on the part. XNUMX: XNUMX: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.

Theory of medical hair removal

Reading Time: <1 minuteRecently, I have been receiving more and more requests to supervise hair removal sites and check the medical suitability of articles.There seem to be very few medical institutions where doctors fully understand the theory of hair removal and perform hair removal themselves.It seems that nurses are in charge of hair removal treatments in almost all medical institutions, but it is questionable whether the nurses read and understand hair removal theory and apply it clinically.When removing hair, the target is the melanin pigment in the hair.Oxygenated hemoglobin is the color of blood, the color of red blood cells in the capillaries within the dermis.The shorter the wavelength of the laser light, the easier it is to absorb the melanin and raise the temperature of the melanin, the better, but in reality, for example, if the wavelength is 400 nm, it will just be absorbed by the melanin in the epidermis and the light will not reach the dermal papilla and bulge area. It just causes epidermal burns.Also, if you are trying to destroy melanin without burning the blood vessels, you might think that a wavelength of 694nm (ruby laser) would be better, but in reality, the shorter the wavelength, the more the light is scattered, and with ruby's 15nm, only a small amount of light reaches the dermis. 750%.For this reason, the wavelength suitable for medical hair removal lasers to destroy melanin in hair and hair roots is approximately 790 to 755nm, so 515nm alexandrite light is suitable for medical hair removal lasers.In beauty salons, hair removal is performed using IPL light that contains various wavelengths starting from 1200 nm.This is because only doctors are allowed to handle 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 1-2 nm was used for medical hair removal) *Factors that affect the hair removal effect 10: Wavelength 30: Pulse width XNUMX: Fluence XNUMX: Number of irradiations XNUMX: Number of hair removal *Client side situation XNUMX: Thickness of hair to be removed XNUMX: Color of hair to be removed XNUMX: Density of hair XNUMX: Area of ​​hair removal XNUMX: Skin color Take these into consideration when hair removal is performed. We will implement it.Theoretically, the spectrum of IPL has been almost completed, and the only way to develop a hair removal device is to increase the fluence by combining it with high frequency or increasing the cooling power, unless there is a problem in terms of medical law and pharmaceutical equipment law.It is important that heat is firmly transmitted to the bulge area and dermal papilla to cause tissue destruction, and IPL, unlike laser, has the disadvantage that there is a lot of diffusion and it is difficult to transmit energy only to shallow areas.If the fluence is increased unnecessarily, epidermal burns are likely to occur, so care must be taken when removing hair for tanned clients or clients with dark skin. Unlike a laser, IPL is a pulsed light that is incoherent, has multiple wavelengths, and has scattering characteristics. Generally, it uses a xenon lamp as a light source and uses a wavelength of XNUMX to XNUMX nm, with the short wavelength region cut off with a filter. Masu.Depending on the application, one or two additional filters are added to limit the wavelength band used for actual treatment.The energy intensity is not uniform and has a peak on the short wavelength side of the oscillation wavelength band. IPL treatment irradiates the skin surface with pulsed light that oscillates in milliseconds through a sapphire irradiation filter.The spot size is often large rectangular, about XNUMX x XNUMX mm, making it possible to treat a wide area in a short time. IPL has different oscillation wavelength bands, settable pulse widths (ex. several milliseconds to tens of milliseconds), pulse division method (ex. single, double, triple), uniformity of output within pulses, and skin irradiation surface for each device. There are large differences in settings and performance, including the presence or absence of a cooling device and its method.

Hair removal equipment development consulting

Reading Time: <1 minuteCurrently, I am being asked by a certain manufacturer to provide theoretical consulting on the development of hair removal equipment.It seems that the general public hardly understands the difference between hair removal at a beauty salon and medical hair removal.Laser hair removal is not allowed in beauty salons.For medical hair removal, there was a time when optical hair removal called IPL was used, but now laser hair removal has become mainstream. Hair removal equipment that adds RF energy to IPL is highly effective, has been used clinically for many years, and is still my favorite.Hair removal equipment has been developed on a theoretical basis.It aims for long-term hair removal effects by destroying the so-called hair center.In the past, the center of hair growth was called the dermal papilla, but it has now become clear that stem cells in the bulge area play a very important role in hair growth.In other words, the hair removal effect cannot be obtained unless the bulge area is thoroughly destroyed with heat energy.I have summarized the knowledge and papers in the bulge area. bulge area The bulge region is a newly discovered organ through recent research.It has the function of promoting hair growth by sending instructions to the dermal papilla, which produces hair.The new theory of medical laser hair removal is that permanent hair removal can be achieved without destroying the hair matrix cells or dermal papilla, which are the seeds of the hair, as long as the bulge area is destroyed and the command for hair growth is cut off. Until now, hair matrix cells (hair roots) have been destroyed.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 treatmentA type of stem cell (cell that produces cells) that was discovered in 2000 to 2001 as part of research on hair.Hair growth factors produced from the bulge region become hair matrix cells, which receive nutrients from the dermal papilla to generate hair.TraditionalMedical 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.
