Permanent Hair Removal Treatment
When talking painless and permanent hair removal treatment, diode laser and IPL OPT machines are unable to avoid. Hair removal treatment carried out by the professional beauty salon equipment is safe, painless and with truly permanent effect. It does not require any numbing cream and it is safe for all skin colors!
Diode Laser Technology
How Does Diode Laser Working in Hair Removal Treatment?
Diode laser is considered to be the golden standard for permanent hair removal. It is safe, painless and very effective way for hair removal. Each session only takes 10- 30 minutes and after 3-6 sessions your hair will gone forever. So it it is one of the most popular treatment among professional beauty salons and medical clinics.
Diode Laser uses a specific 808nm wavelength to treat unwanted hair. The diode laser light energy will breakdown the the pigmentation in the hair follicle. This damage stops hair from growing.
When the laser is directed at the skin, it passes through the skin and is absorbed by the hair follicles. This bright light on the hair follicles causes intense heat. This heat, very short-lived (10ms to 400ms max), can reach up to 75°C and irreversibly destroys the hair root, as a result of which the hair ceases to renew itself.
How Will Diode Laser Wavelength Affects Hair Removal Treatment?
For diode laser hair removal device in the market. There are 2 most popular options: single wavelength 808nm, or the triple wavelengths 755nm 808nm 1064nm. (Read here: What’s the difference between 808nm and triple wavelengths?)
For diode laser 808nm, some people also call it as 810nm. And for diode laser triple wavelength, people also call it as mixed wavelengths or the hybrid laser.
What is difference between 808nm and triple wavelengths?
Diode laser 808nm
808nm is the most classic wavelength in laser hair removal.
Diode laser with 808nm provides deep infiltration of the hair roots with high average power, a high repetition rate, and a big area dimension for quick hair reduction therapy, in this way, can save half the treatment time. The 810nm has a moderate melanin absorption degree making it safe for darker skin kinds. Its deep penetration abilities target the Lump and also Light bulb of the hair follicle while modest tissue deepness penetration makes it suitable for treating the arms, legs, cheeks, as well as beard.
It known as the speed wavelength that can do hair removal very fast make the treatment time faster with very good effect.
Diode laser triple wavelengths
Triple wavelength refers to the diode laser that combines 3 wavelengths to 1 laser stack : 755nm 808nm and 1064nm. When triple wavelength works, all 3 wavelengths works together to do the treatment. And different wavelength good at different aspect:
755nm is considered as Alexandrite wavelength offers more powerful energy absorption by the melanin chormophore, making it ideal for the widest range of hair types and color-especially light -colored and thin hair.
With more superficial penetration, the 755nm wavelength targets the bulge of hair follicle which is especially effective for superficially embedded hair in areas such as the eyebrows and upper lips
The classic wavelength in laser hair removal treatment, the 808nm wavelength offers deeper penetration of hair follicle with high level average power, a high repetition rate and a large spot size 15*30mm for fast treatment.
The deep penetration capabilities of 808nm target the bulge and bulb of the hair follicle while moderate tissue depth penetration makes it ideal for treating the arms, legs, cheeks and beard.
1064nm is considered as yag wavelength which is characterized by lower melanin absorption, making it a focused solution for darker skin types.
All the same time, the 1064nm offers the deepest penetration of hair follicle, allowing it to target the bulb and papilla, as well as treat deeply embedded hair in areas such as the scalp, arm pits and pubic areas.
So the combined wavelength diode laser machine have a wider applicable scope (suitable for all skin types and hair types) and better hair removal effect.
How do you choose from 808nm and triple wavelengths?
Diode laser with triple wave is only 500 USD higher than the single wave 808nm. So if you have enough budget, go for triple wavelengths will never be wrong.
If over half of your patients have very dark skin tone, choose triple wavelengths. (Even you do not have enough budget now, we still suggest you to keep collecting money directly buy a triple wave diode laser. Because although 808nm is good for most of the skin types, but if skin tone is very dark or near to black, definitely diode laser with 3 wavelengths has better effect.)
If you do not have enough budget yet, or you do not have too many black skin patients, a 808nm laser can be a very good and effective option for hair removal.
IPL SHR OPT Technology
How Does IPL Working in Hair Removal Treatment?
Intense Pulsed Light System (IPL for short) projects high-energy light onto the skin like a laser method. Unlike the laser method, IPL uses a wide spectrum of light wavelengths. Before the procedure, a thin layer of gel is applied to the skin for optimal light transmission. Intense pulsed light is directed through the applicator to the surface of the body and the hair is removed. Controlled light pulses pass through the top layer of the skin and are transported to the hair follicles through the melanin of the hair. Melanin converts light energy into heat, which destroys hair follicles and causes swelling.
IPL, SHR, OPT, Are They Same?
IPL, SHR, OPT, they use same technology – Intense Pulse Light. But SHR and OPT are advanced version of IPL. (Read more: The difference of Elight SHR IOL)
IPL (Intense Pulse Light)
IPL system usually comes with several changeable filters for different functions, 480nm-1200nm filter for acne treatment, 530nm~1200nm filter for Vascular treatment, photofacial for light skin, 590nm~1200nm filter for Pigmentation treatment, photofacial for dark skin, 640nm~1200nm filter for light skin Hair Removal Treatment and 690nm~1200nm filter for dark skin Hair Removal Treatment.
And it emit light in bounch, each bounch contains 1-6 flashes. The first flash has highest energy and reduce in next flashes. So Burns are possible due to the uneven impact of the pulse.
SHR (Super Hair Removal)
If the IPL handle in-build with a professional hair removal filter, then it will becomes SHR. This filter which is exactly good for hair reduction will be coated to the crystal. So that the light transfer in and out the filter-coated crystal and delivers to patient follicle directly. It will loss less energy and has better hair removal effect compared with the changeable hair removall filter.
And besides, SHR machine uses the fast flash technology for hair removal treatment, the frequency can reach up to 10Hz, which makes a much faster hair removal treatment than IPL.
OPT (Optimal Pulse Technology)
OPT technology, which also called as square wave technology, means the energy of each flashes is same, will not be reduced. More energy can be delivered to certain areas, so OPT technology can give more effective and much faster results.
Compared with conventional IPL technology, the output power of OPT is always at the same level. At the same time, OPT technology is also SHR technology on the move. The OPT SHR machine can cover the treated area quickly.
Diode Laser V.S. IPL technology
When talking about hair removal treatment, there is an inevitable topic of the difference between diode laser and IPL. There are different in many aspects, from technology, emitter, wavelength, function, spot size, lifespan, sessions, price etc they are very different.
Below is a chart to compare diode laser and IPL from all aspects.
If you need more details, please read this article: What’s The Difference of Diode Laser & IPL Machine?
|Technology||LASER technology||Intense Pulse Light technology|
|Emitter||Laser stack||UK xenon lamp|
|Spot Size||Usually smaller than IPL||Usually larger than diode laser|
|Function||Laser hair removal||Multifunctional including: Hair removal treatment, Acne treatment, Facial thread vein treatment, Pigmentation treatment, Skin rejuvenation treatment|
|Lifespan||20 million shots||1 million shots|
|Session||3-6 sessions get permanent hair removal effect||6-10 sessions get permanent hair removal effect|
|Price||2-4 times higher than IPL machine||Cheaper|
Why it need multiple sessions to get permanent hair removal treatment effect?
The number of sessions varies from patient to patient, but in most cases, 3-6 treatments are prescribed for best results. The frequency of sessions is usually every 4-6 weeks, but this also varies from person to person, depending on hair type, color and natural growth cycle.
We need multiple treatments to get the permanent laser hair removal effect, because each maokong may contains 1-4 hairs, and hair growth has a cycle.
- Anagen: The growing phase of hair, lasts for 2-7 years, takes up 80% of all hair and containing most of the melanin.
- Catagen: The regression phase of hair, lasts for 10 days, hair follicle shrinks.
- Telogen: The resting phase, lasts around 3 months. Along with those hairs which are in resting phase, new hair starts to grow.
Laser works best in the hair in the active growing phase.
Hair follicles in the anagen growth phase have the most melanin, so laser kills the hair in this phase mostly.
Totally 3-5 sessions of laser hair removal treatments is needed to reach all of your hairs during this phase.
The hair stems from the follicle will lose its course texture after every treatment. Meanwhile, hair growth speed becomes slower.
However, very oblivious effect can be seen after just the first treatment.
Hair Removal Treatment Steps
Pre-care of epilation by diode laser machine
- The treatment area must be shaved 24 hours before the hair removal treatment.
- Remove the makeups and lotions.
- Do not wax or tweeze in the treatment area for at least 1 month
- Avoid the straight sunlight exposure.
After-care of epilation by diode laser machine
- After treatment, skin will have some burning sensation ,cooling the treatment area with cooling head for 10 -15minutes；
- The treated area may experience some red rashes, it will vanish after a day or two.
- Do not apply heavy creams or lotions as these may block the pores and cause complications.
- Avoid intense sunlight, sunbed or other artificial tanning for one month after treatment. Tanning after treatment sessions may enhance melanin regeneration, which may result in hyper-pigmentation
- Do not scrub or exfoliate the treatment area within7 days. Do not use chemicals or medications (other than those referred to in these instructions) on the treated area for one week.
Steps of hair removal treatment
Shave the hair & Clean the treatment area
Apply the cooling gel
Set treatment parameters for the patient
Both doctor and patient wear the protective goggles
Start the hair removal treatment with diode laser machine or IPL machine
How To Choose a Suitable Hair Removal Treatment Device?
Make sure to buy from real manufacturer
Except the world famous brands like Alma Laser, Candela etc, most of the professional beauty salon equipment are manufactured by China. No matter you search in Europe or USA or South America or Middle East, you will find the beauty machines looks similar and actually 90% of them are come from China.
In China, there are hundreds of companies are selling beauty salon equipment, but only about half of them are the real manufacturer – there are plenty of the trading companies advertising as the manufacturer but actually they only has several sales persons working in a small office even working in home.
The first step is to make sure to buy machines from a real manufacturer – Because only real manufacturer knows how to build a high quality machine and only manufacturer has engineer team to offer fast technical support, and manufacturer can offer the lowest price based in the same quality.
If the trader sell you a very cheap machine, it means this trader are buying this machine from others in a even more lower price! Imagine, how will such machines be good quality? Actually many traders even not offer any proper after-sales service! So make sure aviod such traders!
However, traders will not say they are traders, so how do you know they are trader or manufacturer?
You can make video call to require the sales person to show you the office and the workshop to make sure they are really factory. If the sales person using any excuses not doing video call, they 100% is not real factory.
Compare price, but do not ONLY compare price
For hair removal treatment, both diode laser and IPL has good effect. But diode laser machine price is usually 2-4 times higher than IPL. No matter what you choose, just to make sure that price should not be the only factor that affects you which supplier to choose.
For example, if you search diode laser hair removal machine in Google, you will find countless distributors and manufacturer with very big price gap from 1500 USD to 15000 USD. That’s 10 times difference huge difference! However, in China, most diode laser machines price varies from 1500 USD to 7000 USD. Two machines may looks very similar from appearance, but they may be very different in the price. Before we buy anything, for sure we will compare the prices, but please remember, do not ONLY compare the price. Because there are a lot of scams in cheap devices.
Some of my clients bought cheap machines from unknown compaies they thought they bought diode laser machine, but actually it is just IPL machine. You will never know what you are really buying by an unreasonable low price.
If you interested, I have spent one week to summarized the different scams collected from my clients and wrote an article to disclose the scams in cheap beauty machines. Please read: Scams in Buying Laser Beauty Machines. Hope you will never meet such scams. And again, compare price is right, but remember do not ONLY compare price!
Choose the model based on your demand, instead of pursuing the “best”
If you have enough budget and want to get the most professional hair removal treatment machine,you can choose diode laser.
If you do not have too high budget – for example you only have 1800 USD, then please do not blindly pursuing “best”. 1800 USD you can get a very high quality IPL machine, but you will never get any real diode laser machine. So if you dream of buy a good diode laser machine at 1800 USD, then you already becomes the target of the traders to cheat – the traders will tell you this 1800 usd machine is diode laser best for hair removal, and actully it is only a 800 USD poor quality IPL machine! (This is not joking, it is really happened with one of my clients)
So, as a professional hair removal treatment machine manufacturer, we truly suggest to buy according to the actual demand, not just pursuing the best or the cheapest.
There is no so-called “the best” model, there is only the “most-suitable” model, as long as this machine is most suitable for you, the it is the best for you.
