Does Laser Hair Removal Hurt?

Does Laser Hair Removal Hurt?

Permanent hair removal has been available in some form for 125 years; the first electrolysis machine was invented in the late 1800s by an ophthalmologist who used the device to treat ingrown eyelashes (trichiasis). Since then, numerous electrolysis machines have been patented, but no new hair removal technology appeared until lasers entered the consumer market in the 1960s.

While electrolysis is undeniably effective, it can only target one hair at a time. The holy grail of permanent hair removal has always been the bulk treatment of many hair follicles at once. This reduces the time needed to treat an area of skin by a factor of several hundred.

The first lasers used in dermatology in the mid to late 1960s emitted a continuous wave, an impractical feature for hair removal since the beam also damaged adjacent tissue. The development of the Q-switch, similar to a camera shutter, allowed the beam to be emitted in timed pulses.

In the late 60s, early laser hair removal devices targetted individual follicles through a wire-thin fiberoptic probe, later modified into a penlight-type device. These devices were difficult to use, just as electrolysis probes are, and in addition were ineffective at destroying the hair follicle. The FDA forced the removal of these devices from the marketplace due to false advertising.

In a repeat of history, the late 70’s saw the introduction of a laser device to treat ingrown eyelashes. This led to the introduction of argon laser equipment to treat unwanted hair elsewhere on the body, but this device also proved to be useless for body hair.

Other dermatologists noticed that lasers used to treat tatoos and vascular lesions produced hair loss in the adjacent tissue, which led to more experiments.

1995 the first FDA-approved laser hair removal device was introduced, the SoftLight by ThermoLase. However, FDA approval does not mean that a device is effective; it just means that according to the FDA’s inspectors, it is not acutely dangerous and makes no medicinal claims that have not been substantiated by research.

The SoftLight used a carbon-based lotion which was rubbed into the skin immediately following hair removal by waxing. Theoretically, the lotion would penetrate into the open hair follicle, and then the laser would be applied to heat the accumulated carbon and destroy the follicle. However, this device proved less effective than light devices that targeted the hair follicle pigments naturally present in skin.

The company which produced SoftLight initially made an excellent profit by offering what they claimed was permanent hair removal through a chain of proprietary clinics called Spa Thira. However, by 1997, a medical study which followed treated patients found full hair regrowth, and in 1998 and 1999 successful lawsuits against the company forced it to cease manufacturing the devices.

In 1997, the FDA approved several more devices which target the melanin in the hair follicle. These devices have better results than the earlier versions; however, some are still so new it is difficult to tell if the hair removal is permanent. Of the 9 laser or light-based systems currently being used, 2 of these use non-laser light. The non-laser technologies use columnated light of many wavelengths which the system operator filters to select the wavelength most likely to be absorbed by the melanin in the patient’s follicles.

Some consumers claim they have experienced long-lasting hair removal with the newer lasers. The treatments are safe if performed properly, and are useful for large areas such as the back or legs, where electrolysis would be a tedious, painstaking process. Even when hair is not completely removed, it grows back finer and lighter. Light-skinned patients with dark hair have the best results. The treatments are said to be more comfortable than electrolysis, and patients can usually tolerate them without analgesics.

3-4 year results are available for some systems such as pulsed light, but most of the newer machines have not been around long enough for long-term data to be available. Also, light-based devices do not work well on blondes or redheads, or people with dark skin. Untrained technicians can cause burns, lesions, skin discolorations and in some cases scars.

It is important to remember that any permanent hair removal treatment must be repeated several times, over a period of at least 1-2 years. At any given time, most hair follicles are in the dormant stage, not producing any hairs, and if there is no dark hair in a follicle, laser/light systems will not have any effect. However, after a year or two, most follicles will have restarted their growth cycle.

  1. You have to be careful of the “scammers” ,
    Here are a few things you should find out before hand
    # Find out the type of equipment used. Make sure its NOT IPL or SPL
    # Find out the experience and qualifications of the technician. As a minimum this should include 5 years experience in skin therapy
    # Word of mouth is also a good indication. Positive experience from people who have undergone treatment is a good sign.
    # Be aware of false adverstising and heavily discounted treatments.

  2. Yes, it hurts, but clinics do offer numbing cream. It really helps ease the pain. It kind of feel like ant bites. It is the best thing I did for myself. Wish I could have done it sooner.

  3. You can't answer this question until we know which laser machine do they use. Normally it hurts a little bit .Usually the treatment causes 1 to 3 hours and needs a repeated treatment every 6 months or 12 months until the whole hair follicle gets damaged. Repeated treatment is needed as some hair follicle get escaped. So how many times …..it depends on the machine, the person doing the treatment and finally the body nature of yours. A treatment session may cost $400 to $3000 and more according to the area and clinical charges
    More on the working of laser can be found on http://www.beauticianworld.com/hairremoval/laser.html

  4. Yes, it hurts. Usually you are given a numbing cream to lessen the pain.

    There is nothing that is permanent. So its actually laser hair reduction. so yes, you can be totally hairless in some areas, but once a year you may need a touch up. You go 5-8 times of treatments.

    Its expensive. The larger the area the most expensive. Every place is different. Go for a consultation, they are free. But usually you are looking to spend at the very least a few thousand fo those areas.

  5. Its just like some ants bite.
    Normally is 3 times for per underarms.
    After which some little hairs still grows, but its colourless.

  6. Plucking (tweezing), Shaving, Depilatory creams and Waxing are temporary hair removal methods. Waxing usually lasts for 3 weeks, but it is painful. Electrolysis and laser hair removal are "permanent" hair removal methods but are expensive and you have to find a trained professional, otherwise your skin could be damaged. A review of the various hair removal methods is available at http://3rc.info/

  7. ive had laser on my bikini line, ive had 6 sessions so far.
    yes it does hurt,it kind of feels like being flicked with an elastic band but x10! the only good thing is that the pain goes away almost instantly.
    depending on how course your hair is will determine how many time you'll need to go. i've probably got about 4 more sessions until i'm finished, then ill never have hair again!!
    laser is permanant so once you've finished you wont have any hair left

  8. Laser hair removal has actually been surpassed by IPL hair removal (in Australia – that is). As a Laser Aesthetician I have used and experienced both. I have dark hair and olive skin. I did have some hypopigmentation from the Ruby Laser but it resolved. I have had no side effects from the IPL and all my hair has gone…. legs, underarms, bikini. It's wonderful, not having to worry about it anymore. Both laser and IPL are attracted to the melanin in the hair and only goes as deep as the hair root.It is not invasive at all and feels like a slight rubber band flicking the skin. It doesn't cause cancer !!!! Either way it will take several treatments to be hair free.

  9. I had my second treatment on my legs, bikini area, and underarms yesterday. It "hurts" you skin in the sense that it is painful. It feels like snapping a rubber band against your skin or being poked with a sewing needle over and over again. But it doesn't "hurt" the skin in the sense of damaging it. Laser hair removal does no damage to the skin if the skin and hair are completely different colors. Darker complexion people like Spanish and Black people cannot have laser hair removal done because their skin and hair are similar in color. The laser basically burns the hair follicle because it is dark, and it doesn't burn the skin because it is light. It targets darkness. So a black person who used laser hair removal would probably lose their hair, but their skin would blister and peel horribly, and no medspa or dermatologist would do laser hair removal on them.

    I would tell you everything about my experiences but since that would take many pages I'm going to stop with answering your question. If you need to know anything else about it just E-mail me

  10. No it does not! It's the best thing to come out since the vibrator!
    OMG, did I just say that out loud?
