We must understand the differences between IPL and laser hair removal before we can fully appreciate their effects. The followings are the specific introduction.
What is laser hair removal?
Lasers have monochromatic focused beams. Monochromatic refers to a laser that has one wavelength or only one color. The wave’s crests and valleys are aligned. The wavelengths that melanin in hair absorb is between 600–1100nm, so there are many professional lasers that can remove hair. There are four types of professional lasers that can remove hair: the Ruby Laser (694nm), Alexandrite Laser (755nm), Diode Laser (805nm), and Neodymium: Yttrium Aluminium Garnet Laser (1064nm). The laser pulse is absorbed by melanin-containing cells in hair follicles, which then convert into heat. This slows down hair growth and eventually achieves the perfect result showing no hair regrowth.
Since Theodore Maiman invented the first laser in 1960, it has been used in many ways. Scientists discovered that lasers could be used to remove hair in the 1970s. The beauty industry was interested in laser hair removal and funded research to create machines. Laser hair removal became widely available around 1990.
What is IPL hair removal?
IPL stands for Intense Pulsed Light. Although it is not a laser, IPL uses light energy to reduce and slow down hair growth on the face and body. IPL uses a xenon Flash Lamp that emits diffused, incoherent light. It is composed of many wavelengths and colors, so it cannot be focused like lasers. The IPL is fast and coherent, with a wavelength range of 500 to 1200nanometers. Different wavelengths are absorbed by the chromophores within our bodies.
The IPL filter removes unwanted wavelengths in order to target specific chromophores. It leaves only wavelengths between 600–1200 nanometers, and then multi-wavelength flashes from IPL are absorbed by the melanin-containing cells of the hair follicle. This heat causes hair to shrink and it stops growing completely. Different areas of the body have different hair diameters and depths, so it requires targeted “hair removal strikes.”
1976 was the first year of clinical trials of IPL for treatment of vascular lesions. The 1997 clinical trials of an IPL machine commercially available are the first to be reported, especially forIPL laser hair removal at home.
The difference between laser and IPL hair removal
Laser hair removal
Lasers are monochromatic (monochromatic) coherent light (i.e. all crests and troughs of the wave are aligned)
Melanin can be targeted using a single specific wavelength of light from a laser. Melanin absorbs energy at a range of different wavelengths (600 to 1100 nm). The laser is a single wavelength, so hair removal lasers can have different wavelengths, such as diode lasers at 810 nm.
Focus to a point. Different types of lasers reach different depths.
Lasers are effective on dark hair.
The laser processing area is small. It works on the face and smaller body areas, but is time-consuming for the legs. At least 1hour
IPL hair removal
Intense pulsed light is a fast flash of multispectral (multIPLe colors) incoherent light.
It can be targeted using a range of wavelengths from the IPL. The wavelength of IPL is between 500 nm and 1200 nm. It is filtered to 600 to 1200 nm for IPL hair removal.
Xenon lamps produce IPL, which is directed at the skin through a filter head made of quartz or sapphire, for example.
IPL for dark skin and blond hair.
The IPL processing area is larger and the processing speed is faster.
professional IPL machinesuch as underarm laser IPL hair removal, upper lip laser hair removal and facial IPL laser hair removal can be used for different purposes and parts of body. in 10 to 30 minutes with the latest and fastest equipment.
The principIe of action of laser hair removal and IPL laser hair removal
Laser hair removal and IPL laser hair removal work by destroying the hair follicle area and key cells.What is the follicular area?The hair follicle is a pocket in the skin that encloses the hair shaft, and the follicle controls the hair growth cycle.Dermal papilla with fibroblasts, hair matrix, outer root sheath and epithelial stem cell bulge are the structure of the hair follicle area. The dermal papilla fibroblasts and the epithelial stem cells together influence the growth cycle of the hair follicle.There are 3 phases of hair growth: Phase 1: anagen phase (active growth phase), Phase 2: regression phase (cells stop growing) and Phase 3: resting phase (hair follicle inactivity).
If enough heat is applied to destroy the dermal papilla fibroblasts and epithelial stem cells, they will not be able to start a new hair growth cycle. Therefore, the damage is irreversible and the result is that the hair follicle shrinks or remains dormantin most cases. Destruction of the stromal keratin-forming cells will cause the hair to stop growing and possibly fall out within a few weeks. However, if only these stromal keratin-forming cells are destroyed, the hair will remain as thick as before. This is because intact dermal papilla fibroblasts and follicle cells can still trigger terminal hair growth in the next anagen phase. Therefore, the best hair removal for menand the best hair removal for women of laser hair removal and IPL laser hair removal will damage all 3 key cells, resulting in long-lasting hair removal results. With laser hair removal and IPL laser hair removal treatments, hair removal and regrowth inhibition can be achieved during the anagen phase.
With the development of the medical aesthetic industry, hair removal technology is also constantly innovating. One of the more popular hair removal devices belongs to the Sapphire ice point hair removal device. It uses the principle of selective photothermal actionso that the semiconductor laser through the sapphire and the hot light filters into cold lightdirectly to the skin surface.Melanin hair follicles selectively absorb laser energy, and the temperature rises sharply resulting in a photothermal effect so as to destroy the surrounding hair follicle tissue and achieve the effect of permanent safe painless hair removal.
How to choose IPL laser hair removal？
IPL laser hair removal device should be professional, effective and less painful. At the same time, an IPL laser hair removal at home device should also be clean, comfortable and high value.
Different parts of the body have different hair follicle depths and hair diameters. Most hair removal device products on the market are single-headed, with a single band for the whole body or intelligent identification of skin hair removal, having inadequate professionalism and poor experience.
Jovs Venus Pro ll generation hair removal device, with six modes corresponding to six body parts, to provide the best light wave program, can be seen as the option of professional IPL machinesuch as underarm laser IPL hair removal, upper lip laser hair removal and facial IPL laser hair removal. There are several strengths of it as below.
-
Grade Ice-Cooling hair removal care brings to IPL painless hair remover experience.
-
The patented 330°rotating head takes care of every detail of your body.
-
Hospital-grade SR photorejuvenation mode used IPL tech, with the remarkable effect of skin resurfacing and brightening.
