“Today we were talking in our Patients Code of Care conference in our practice about the things that a lot of questions that come up and one of them that frequently comes up because there’s so how much technology on the market now for laser hair removal and the question is which machine is the best and the answer is probably isn’t the best machine for any particular individual but there are certain machines that are better than others and I’ll tell you right now there are couple of factors or features that one should look for and first its simple explanation about how laser hair removal works.
Laser is what it sounds like, its amplified light energy but its one wavelength with light and the reason that the wavelengths for hair removal are chosen are basically two factors. One of them is “How much light absorption occurs from the hair to the hair itself from the laser energy delivered?” so when the laser fires the laser goes basically through the skin to a certain level, the longer the wavelength of light energy the deeper it will penetrate in the skin, skin is pretty think and the hair is pretty deep so this is in the form of millimeter range and so longer wavelengths of light in general would be better but also the shorter the wavelength to light the more energy is absorbed by the melanin so melanin is particularly absorptive of shorter wavelengths and there’s actually a couple of peaks on this melanin is that the skin pigment we have melanin absorption curve. In those peaks that occur and this is just of interest you don’t have to go out and look up any chart but i have some available we can actually show one. On the melanin absorption chart there are wavelengths around 800 nanometers where there’s a lot of absorption of energy by melanin. There’s a wavelength of energy about 755 so a little shorter with peaks a little bit shorter wand then there’s one up longer about 1,064 nanometers and those three all represent vast majority and let me vast majority of the laser hair removal machines. Machines that can generate laser energy in those wavelengths. So one is Alexandrite laser that’s a 755, there’s a diode laser like the light cherry teeth that is at 800 to 810 nanometers and then there’s several devices that are at 1064 in the Yag laser is the molecule that’s used to accelerate or amplify and heal the light, laser light.
So if one is choosing between those 3, now we have three wavelengths to light. We have the 800 nanometer Diode, the 755 Alexandrite and then the ND: YAG 1064.
There’s not a really a best answer. I would say there are certainly better piece of equipment in different companies. I’ve chosen the Light sheer duet as a duet mostly because the spot size is this bigger round and its completely painless so you can cover large areas of hair in a very short period of time and have no pain because i think there’s almost completely painless in the use of Light sheer duet had and you feel a little tingling basically, that is a big benefit because historically pain has been an issue with hair removal. Now when i compare to waxing or some of the other methods of removing hair it’s really not that painful no matter which of the devices you use or which wavelength you choose.
So that wavelength the 800 is very, it’s in the middle, it’s very high on the absorption curve, it’s not a really long wavelength so if you had particularly thick skin that wouldn’t be as good but it absorbs the light energy very efficiently and then the longer wavelength ND: YAG might be used for darker skin patients in a lot of cases because it’s a lower on the melanin absorption curve with that said we got ways of adjusting, in fact all of the devices the Alexandrite, the Diode and the ND: Yag for a design for hair removal can all be adjusted to skin color and types. So really even African-American can do laser hair removal and many actually need it it’s a condition called Tinea barbae where the curly hair gets stuck underneath the skin on the neck while shaving and that causes a lot of problems with skin bumps and inflammation with unattractive, it can even cause some scarring and those patients are very, very good candidates to doing hair removal a long lasting treatment for the permanent reduction of hair and the more or less qualifier are saying we’re talking about the devices that laser hair removal, we call it permanent hair reduction at any given time when we’re treating somebody probably 60 to 75% of the hairs are growing and we don’t want them to be long we want to shave them flush with the surface in preparation to the treatment but we also know that some of the hair to resting and in resters actually a hair in the hair shaft, in the tunnel to which the hair travels then there’ll be no heat absorption and nose follicles will be undisturbed unheated and untreated so that’s why we need multiple treatments at least 3 weekend on both between them and usually it’s a bit longer so that we can target all of the hairs whether they’re growing actively at the time of treatment or if you wait a little bit when the other follicle become active and still growing so that’s the important concept. Hair removal takes several treatments to accommodate for the rest of the face and the hair growth cycle.
Three basic technologies, I didn’t really name any names except the one we are using. They’re all very effective and largely it’s the hands of the operator sort of simplified as they’ve tried to make it really comes down to the expertise or the person delivering the energy and looking at the skin tissue and laser interphase watching that action and making sure we’re maximizing the energy delivery in destruction of hair and hair follicles and minimizing the chance of skin injury where you get blisters or getting the source didn’t have to do wound healing and I’ve certainly seen those as referrals so we want to avoid who does it if we can, completely.
