IPL Hair Removal Effectiveness

I´m studying skin therapist in Stockholm and I´m working on a study about laser and IPL. And the question is : which technology is the best for hair removal? I´ll also buy a machine for my clinic in october 2008 and I´m searching for a machine that is effective, safe and works on a wide range of haircolors as possible. I´ve also read about diodlaser, a combination od radiofrequency and IPL, and that it´s the newest technology.

Lasers are more effective than IPL for hair removal

The most effective hair removal occurs with lasers not IPL. In addition, IPL is least effective and has the most side effects for darker skin types because it does not have the correct wavelength range (1064 nm) to effectively treat this skin. The most effective types of lasers for permanent hair removal are:

  • Diode and Alexandrite (light skinned patients)
  • Long Pulsed Nd:Yg (dark skinned patients)

If you are in Stockholm your best bet is going to be the Lumenis Lightsheer for safety, efficacy and durability. It is the gold standard for light skinned hair removal.

Lasers are better for hair removal

Nancy,

Most laser hair removal studies show that for permanent "Hair Reduction" 755nm or 810nm Lasers work the best. Dark hair responds the best and blond hair has the poorest response. Many treatments will cause the hairs to enter telogen, but don't offer good hair reduction when patients are followed long term.

Lasers are betters than IPL for hair removal

IPL and lasers can both be used for laser hair removal. IPL is safer for darker skin types but it takes longer to achieve permanent results. Diode lasers are usually very effective and work best on light skin and dark hair. They also require less treatments.

Lasers or IPL for hair removal

I use both. The lasers work better and are safer for darker skinned patients. But, I feel that alternating the two during alternate treatment sessions is more effective than one alone.

Lasers vs. IPL

Both lasers and ipl can be effective. For an understanding of which modality is right for you, visit an experienced practitioner.

IPL Hair Removal Effectiveness

Both methods IPL or Diode laser are effective for hair reduction. However the way IPL is delivered in a pulse type fashion is not as comfortable for the patient compared to the Diode laser. The newest technology in Laser Hair Removal is the Diode laser. This technology employs selective photothermolysis to target the specific target such as the melanin in a hair follicle resulting in disruption of hair growth. This technology offers the deepest penetration levels and melanin absorption. The great advantage of this technology is patient comfort and skin protection as it has a cooling device that protects the skin from thermal burns. The diode laser is also safer to use on higher Fitzpatrick skin types vs. IPL.

Lasers are the Preferred Option

While IPL is indicated for the reduction of hair growth, it has it's limits.  It is not particularly safe or effective on all skin types or hair colors.  In my experience IPL has not been as effective as lasers.  There are multiple options when it comes to laser hair removal. Not only are there different wavelengths, there are also many brands.  There are many good devices, just some work better than others based on the individual patient. A 1064nm Nd:Yg (Yag) is effective on all skin types, but is best suited for darker skin types.  A diode laser, 810nm, which is again effective on all skin types, but is better for lighter complexions.  If a patient is a candidate for both, I prefer the diode. We have the Soprano Ice, a newer model of an 810nm diode, and we have seen very good results on all skin types.

What is the effectiveness of IPL for Hair Removal?

Hi there, 

I recently did a review of this topic and posted it about it in a blog I wrote. If you are interested in learning more about IPL's it may be usefull to check it out.  There are some studies that compare diode lasers to IPL and I mention them in the article.

Studies Show Both IPL and Lasers Work for Hair Removal

I love reading answers that pop up with questions like this. The issue is not which works better, but which does the doctor answering the question have that he or she wants to promote that is at play here.

Some of the answers already given are correct: both work, and there are clinical studies that support one versus the other and vice versa. I did the original IPL hair removal studies. I like this technology but do more laser work these days. Lasers are faster for the most part, they are not as painful, and they work efficiently for my patients. But remember, both work.

IPL or Laser - which to choose?

Light, be it IPL or Lasers allow you to achieve hair removal because the hair follicle and hair shaft absorb light of certain wavelength's or colors and reflect the others. That is why objects look a certain color - because they reflect to your eye the colors they DO NOT absorb. In the case of hair, you want to deliver an intense pulse of light to the hair follicle and shaft of a color that will be absorbed by the tissue. This causes sudden heating of the tissue and its ultimate destruction.

First it is important that you understand the difference between the two technologies -

1. IPL - Intense pulsed light (also known as BBL - broadband light on the Sciton machines) - this is highly concentrated pulses of light of many different colors (wavelengths). It is effective against hair because some of the wavelengths of light delivered are absorbed by the tissue and result in follicular heating and destruction.


2. Laser - This is light of only one wavelength or color. It is collimated which means all the rays of light are parallel and not scattered as with IPL. If the wavelength of the laser light beam matches what the target tissue (the hair follicle) will absorb, then you are using all your available light energy for the purpose desired and so it is more efficient. there are many different wavelengths of light used for hair removal, to name a few of the more common:


Nd-Yag 1064, Alexandrite 755 and Diode 800 but there are many more types for different purposes. Some lasers are best for darker skinned patients to reduce the risk of pigmentation problems. Some lasers are faster for hair removal (ie diode) than others (Alexandrite).
There is more to this than just picking a wavelength - you have to consider the delivery system - is the laser energy delivered evenly to reduce risk of burning the skin, how do you make adjustments to protect from burning the skin or getting post treatment pigmentation problems.


I did many years of research on the technology before pulling the trigger and purchasing a system. Although there are several good systems around, I settled on the Palomar Vectus LASER system for a few reasons:


1. It is a Diode laser which makes it useful for skin types I - VI.
2. The delivery system has a broad treatment area making it quick and easy to obtain excellent results on even the most challenging of surfaces like a hair male patient's back.  In comparison tests with the Lumenis Duet system, also a very good system, it performed much more efficiently.
3. The energy dispersion is much more even than the Duet, so there is less risk of burns and undertreated areas.

4. SAFETY - this is a big one for me - it has a "Skin-Tel" system which allows the operator of the laser to take measurements of the patients melanin content (pigment) in their skin and the computer in the laser makes automatic adjustments in the energy delivery so as not to over treat or burn a patient.


My office has had this laser for almost two years and we are very happy with it as are our patients. I hope that this answers your questions.
