Photo-Epilation Refers To All Laser Or Intense Pulsed Light Hair Removal Methods
In epilation methods the follicle is targeted to be removed together with the hair shaft. The most requested of all of the epilation treatments are pubic laser hair removal. Great results are achieved with ingrown pubic hair. Pubic hair styling (hearts, diamonds etc) can also be done. Removing hair by photo-epilation is still a relatively young application. The first laser to attempt this technique was the Q-Switched Ruby laser in 1995. The rate at which energy for a laser is delivered can be either a continuous wave (Diode) or interrupted wave(Q-Switched Nd:YAG). The interrupted wave is known as a pulsed wave, but strangely the intense pulsed light (IPL) machine uses continuous wave that is delivered in very short bursts.
The three skin chromophores are melanin, haemoglobin and water. Different lasers target different chromophores. Laser vs Intense Pulsed Light
Clinical data have gradually been gathered for each type of laser, from Alexandrite, Ruby, Nd:YAG to intense pulsed light or IPL. Lasers were initially sold as the first and only machine that can achieve permanent hair removal. But many laser manufacturers had to eat humble pie and revise this claim. The FDA (Food and Drug Administration) only gave approval to electrolysis to use the term "permanent hair removal". All photo-tricholysis systems have to use the term "hair reduction". Both doctors and patients now have more realistic expectations of this treatment. Depending on factors such as colour, texture and location of the unwanted body hair, it is now generally accepted that hair can be removed for up to one year with photo-epilation methods. Once regrowth starts again, hair is both fairer in colour and fewer in numbers. Fine vellus hair do not react well to the light-based method. Does Laser Hair Removal Work?Yes, laser hair removal results are very good. And so are the results from intense pulsed light (IPL) machines. There are other photo-epilation machines too.Very good hair removal results are achieved with thick, dark terminal body hair – the kind men have but don’t want! Men increasingly request permanent pubic or genital hair removal. More specifically brazilian hair removal and bikini area hair removal. The temporary methods like shaving and depilatory creams have the unwelcome side effect of ingrown hair. Photo-epilaton devices do not work on white, grey, light blonde or red hair. All these hair types have a total absence if dark pigment (eumelanin) in the hair. Dark pigment is needed to absorb the light that must convert to heat to kill the dermal papilla that nourishes the follicle. What Does Laser Treatment Cost?Laser hair removal cost is extremely high, because the cost is directly related to the purchase price of the laser machine. Lasers are very expensive, because the technology is very advanced.The treatment price of laser hair removal is always much higher than the price of intense pulsed light treatments. IPL and laser hair removal results are equally good and satisfying to customers. Intense pulsed light machines cost less, because the technology are less advanced. Photo epilation devices are extremely sensitive machines. They should only be moved with the utmost care and then only when it is really necessary. After being moved the machine will have to be callibrated again at huge cost. So don't be fooled by manufacturers’ claims of "permanent laser hair removal at home". Or also "portable permanent laser hair removal machine". Be warned! You will only waste your hard earned money. Why Is Skin Cooling Important?Please follow this link to read about my daughter's and my own first hand experience with a nasty laser hair removal side effect. Luckily most photo-epilation hair removal induced side effects are rare and not permanent.It is advisable to always use skin cooling (minus 4 degrees Celsius) before, during and after photo-thermolysis treatment to reduce IPL and laser hair removal risks. My own intense pulsed light machine has a built-in cooling device that works on this perimeters for the protection of the client's skin. I have never burnt any client's skin. Cooling saves the skin from overheating, burning, blistering and eventual hyper-pigmentation. The proteins in the hair shaft, the follicle and dermal papilla are coagulated by this rapid heat increase of about 70 degrees Celsius for the duration of 0.02 seconds. Only hair in the growing anagen phase will be coagulated. Photo epilation is ineffective on hair in the catagen and telogen phase of the hair cycle. Once a follicle is killed it can never produce a hair again. How Is Light Absorbed By The Skin?Selective photo thermolysis is used for photo-epilation. The high concentration of the chromophore eumelanin in the base of the follicle is targeted to absorp the extremely high intensity light beam that is delivered to the skin.The dark melanin absorbs the light and is turned into heat energy. If no dark melanin are present (eg grey hair) no heat will be produced inside the follicle. If the skin is light in colour (little dark melanin) not much light and heat will be absorbed by it. But with a dark hair most of the available heat will stay inside the follicle, resulting in its death. This means the minimum damage is done to the skin surrounding the follicle. Darker skins on the Fitzpatrick classification scale have much more melanin present in the skin, meaning more light and therefore more heat will be absorbed. This might even lead to burning of the skin. Different Types Of Lasers
Lasers suitable for hair removal always fit into the infrared range (750nm to 10,000nm) of broad spectrum visible light (380nm to 750nm). The four main hair removal lasers are Ruby (690nm), Alexandrite (780nm), Diode (810nm) and Nd:YAG (1064nm). Intense pulsed light (IPL) has a standard range of wavelengths between 500-1200nm and is therefore also suitable for hair reduction. Lasers And ColorThe optical window for melanin absorption is 600-1350nm. Ruby has the highest melanin absorption and Nd:YAG the lowest. Diode has the highest haemoglobin (blood) absorption and Ruby the lowest. Some laser types are more suitable for acne treatment, others for tattoo removal and others for vein removal.Cosmetic lasers are in high demand. The typical cost of laser hair removal and tattoo removal prices must be discussed with the salon of your choice, because prices differ substantially. I have only started to scrath the surface of the intricacies of photo-epilation technology. Maybe you are beginning to appreciate why these treatments are so very, very, very expensive.
