Importing your own laser and IPL equipment.

We often get the question from students: “What do we think about importing your own equipment from China?”

Chinese made laser or IPL

There is no easy answer to this question.

Before you can start thinking of buying equipment you first need to answer two questions for yourself.
Firstly, what would you like to do? (What treatments or services would you like to offer your client?)
Secondly, what technology would serve you best to do these treatments you would like to offer?
These two questions you have to answer before looking at equipment, whether importing it for yourself or buying from a local agent.

The only way you can answer these two questions is to start your journey with a solid education in the treatments and technologies that you have in mind.

Once you have decided on what it is that you want and that you would like to import it yourself from China there is one very important factor that you have to remember: When you deal with Chinese manufacturers the first thing you have to realize is that English is not their main language. This is very important, because it may lead to various miscommunications on both sides of the negotiations. It is therefore important that you spend time in reading and writing emails various times before coming to a conclusion. The same is also valid for the user manual(s) that will accompany the equipment. Do not except that it will be written in a form of English that you can easily understand.

Other factors that you have to keep in mind when dealing with a foreign manufacturer directly are practical training on the specific unit(s), technical support and availability of consumables (like flash lamps). If you can get a suitable solution to all of these points, you may save yourself a lot of money by importing your own equipment.

However, on the other side of the coin, you may end-up with something totally different than what you have had in mind.

Many newcomers to the industry think that a Nd:YAG laser is the same thing whether you buy it in China or America. This is a total misconception. It means that the machine from China and the machine from America will have the same wavelength (1064nm), but apart from that it will be two totally different machines. The wavelength is no indication of the overall quality of the machine.

Evaluate all the properties of a machine before you buy it and not just the wavelength. The ability of the machine to provide good results lays in the combination of all the properties of the machine and not just in the wavelength.

A word that appears more and more nowadays in media is biomodulation. Biomodulation is a better descriptive word than low-level laser or LED-therapy for the biological processes stimulated with low energy photon irradiation.  With the advancement of low-level lasers and LED’s, it has become more probable that the devices utilizing these technologies also create a thermo reaction (heat reaction). With biomodulation this thermo reaction is absent, irrespective of the technology used.

Photo-biomodulation has become the collective name for what was previously called LLLT, soft laser, cold laser, LED-therapy and cold light therapy. These names all referred to treatments where no thermo reaction was created. The light is only used to stimulate existing chemical reactions in the body.

Biomodulation, itself, is the process following a photochemical reaction. Photochemical reactions can be compared to photosynthesis in plants where the light causes a chemical change when it is absorbed.

Which treatments are generally seen as biomodulation treatments?

This can be any treatment done with low-level lasers, LED devices or other low energy output light devices. You will find these treatments in beauty, lifestyle and medicine. The most important factor is that the light does not create a thermo or ablative reaction. Only a chemical reaction.

How much energy is required for biomodulation?

There are more and more evidence that biomodulation has a biphasic dose response. This means that effective treatment require a minimum level of energy to achieve a therapeutic (beneficial) reaction and as the energy is increased from this minimum level upwards the therapeutic reaction will improve until it reach a maximum therapeutic result. When more energy is applied after this maximum therapeutic level has been reached the results will decline and at some point a too high energy level will give negative therapeutic results.

In general it seems that the best biomodulation results are between 2 J/cm2 and 8 J/cm2 (depending on various factors).

You will find some more information about this in the paper: “Biphasic Dose Response in Low Level Light Therapy – An Update” by Huang, Ying-Ying; Sharma, Sulbha K; Carroll, James; more…

Laser hair removal

Although one of the most common treatments performed with lasers and IPL’s; laser hair removal still remains a regularly discussed topic with some stubborn urban myths about it.

Let us start with the question: What is the difference between temporary laser / IPL hair removal and permanent laser / IPL hair removal?

When the hair root is not sufficiently heated to kill the hair papilla the hair will shed, but a new hair will grow again from the same papilla. The hair free period can be up to 3 months.

On the other hand if the papilla is killed there will not grow another hair from it.

Shedding of the hair after a treatment does not indicate permanent results

How does laser hair removal work?

The light emitted from the handpiece gets absorbed by melanin which then heats-up. Because the hair root contains a high concentration of melanin there will be enough heat created to damage the tissue surrounding the hair root to such extend that no further hair growth will occur from that specific hair papilla.

To achieve this there must be enough energy (light) available for a sufficient period of time to heat up the hair root. The real secret to success lies in the energy and pulse length combination. Too much energy in a too short period will lead to destruction of the hair itself without sufficient damage to surrounding tissue (shedding of the hair and temporary results). Too little energy will cause very little or no visible results and sufficient energy with a wrong pulse length will also deliver temporary results.

What happens to the skin since it also contains melanin?

It also heats-up. The melanin in your skin is exactly the same pigment as the melanin in your hair. For this reason skin cooling is a very important component of successful permanent hair removal. The epidermis must be cooled during the period that the laser emits the light beam.

This cooling will not affect the heating-up of the hair root since the skin is a very weak conductor of heat and both the cooling of the epidermis and the heating of the hair root are local processes.

Thus the lighter the skin is the safer the procedure will be and the darker the hair gets the better the treatment results.

Cooling gels are very ineffective in protecting the skin during a treatment. This is because of two simple reasons:

Firstly, the cooling gel will be pressed away by the handpiece and thus not provide a sufficient protection layer.

Secondly, if the cooing gel is not pressed away and a distance is left between the handpiece and the skin the light will be reflected and refracted to such an extent by the gel that the treatment will not achieve the desired results.

In practise the use of cooling gel during a treatment indicates that you should only expect temporary results and not permanent results.

What is the difference between a laser treatment and an IPL treatment?

Lasers only emit one wavelength of light at a given time. This means that less elements in you skin and body will react to the light during a treatment and the treatment will be much more focused. (Using a wavelength of 750nm will not affect elements that react to 680nm.) For this reason you will get lasers that are suitable for hair removal as well as lasers that cannot do hair removal. There is also no (or very little) loss of energy.

IPL’s emit a broad range of light that is filtered (usually) between 500nm and 1100nm. Because of this the handpiece must be placed directly onto the skin or else too much loss of energy will occur. In turn this leads to a high heat build-up in the epidermis. This is also the reason why IPL’s are not suitable for dark skin types.

Various manufacturers claim that their IPL’s are safe for dark or all skin types. This is only achievable if you lower the energy to such a level that permanent hair removal can no longer be achieved.

Can permanent laser / IPL hair removal be achieved on all skin types and hair types?

No. The hair and hair root must contain a sufficient concentration of melanin to generate enough heat to destroy the hair papilla.

The ideal person for permanent laser / IPL hair removal will have very light skin and dark hair. However, this ideal person exists rarely in reality. The bigger the contrast between skin and hair, the better the results will be.

Is laser more dangerous than IPL?

No.  In the hands of a well trained therapist both technologies will provide the desired results in a safe manner.

Because of the wide range of wavelength and heat build-up, IPL’s may lead more easily to skin burns.
