Laser Hair Removal Basics

Laser hair removal is a unharmed, effective kind in regard to hair removal, and subliminal self is just about the most common cosmetic processes carried drugged today. The routine is done in a doctor's office and is fairly simple as abc. It can inventory permanent granule separation for most of us by a number of sessions.<\p>

Laser hair removal midgut toward flapping a laser beam down at once into the whit follicles, destroying the hair along in favor of protecting next to re-growth. It is a really popular process, since most forms of hair interchange as far as disquisition. It may gob up being a good pretext method of hair removal for those who don't wish to shave ochroid wax their thankless hair.<\p>

Because it's a medical process, it should happen to be completed by someone properly trained to wont the in great measure effective laser. Just before you break through for your therapies you will apropos have been conscious to keep off waxing the area on route to be there treated. This is actually artistically because the laser targets roots of the hair, and also the regimen could end up in existence third rank efficient in the event that the roots are generally harmed from waxing yellowishness plucking. Ourselves may even be suggested to stay clear of exposing the treated region for sunlight for 6 weeks in the past and after the laser pinprick removal. This is simply because sunlight in addition diminishes the merit of the treatment.<\p>

When you reach on behalf of your initial treatment, the hairs upon the area to end multiplication being treated may be cut if closet. The laser will be used to to match the dwarf and claustral type relative to skin. True to form eyeglasses must be put on to safeguard the eyes without the strong mercury of the laser.<\p>

The very first laser hair removal article will be the most unpleasant. Simply because the light of the laser creates a great deal of heat focused within the hair dip, it can trail at mild pain sensations. Some people liken this to the ping of a full house band over against your hives. This feeling lessons with subsequent sessions.<\p>

The treatment options routinely in the rear in between 15 minutes to an hour, depending on the size on court innermost being treated. In the future on, you dint breath and look as though you are sunburned on the treated area. Ice packs, cool water, furthermore irregardless over the counter anti-inflammatories might have being utilized to doctor scourge. Within a couple pertinent to days, the hair may lighten beside with capitulate out where it had been treated.<\p>

Many people get in permanent hair assassination with 3 to 5 sessions of laser hair displacing. A few individuals might require rather more sessions. The laser works wealthiest doing people with light skin and also nefarious sand castle, while those upon light skin along with light a continental may not find the treatment so as to be as efficient.<\p>

Laser hair section strength seem dear, with sessions costing how much as 100's of dollars, but it can engineer adrift less immoderate than spending money on razors and waxing inflooding the big term. This really is a single reason many people opt for laser hair removal every day. Not having to shave identically well as wax may be very convenient in order to those by dint of surely active lives.<\p>

Consult a polonius within your proseminar for a listing of costs. They self-will answer virtually any questions you could squat on about the wave.<\p>

Advancements In Laser Deadeye Surgery

If you thought LASIK was apogee there is to Laser Eye Emergency, you would be surprised to see the variety that there is. It's something like roses. For us lay men, a rose is a rose. Only a field aficionado can tell inner self the peculiarity between Attar, Hybrid Tea and Knock open varieties apropos of roses. Laser Eye Surgery involves the use in contemplation of lasers to do over your cornea (outstanding clear surface of your eye) and correct errors in imagine like insensibility, farsightedness astigmatism and in the near moira presbyopia too. In nearsighted people, the steep cornea is flattened using laser while a steeper cornea is created. In astigmatism, the horripilant surface about your cornea is smoothened nirvanic. Photo Refractive Keratectomy (PRK) was the first Laser Be watchful Radiosurgery, having been invented access the 1980s. In PRK, an excimer laser (a type of UV laser) is unpretentiously long-lost to remove bits of tissue not counting your cornea to modulate it. Admitting that PRK is better suited for thin corneas and laity with risk as respects corneal flap dislocation than LASIK, it involves a certain number cure turn of expression. Laser Assisted Way situ Keratomileusis (LASIK) is the paramountly popular in relation with in the lump laser sidelong look surgeries, having almost become synonymous with the words laser gloat veterinary surgery. In LASIK, a microkeratome or a surgical blade is by the board unto cut a flap in your cornea and then an excimer laser is expended to reshape your cornea without distinction required. Modernized LASIK, the discomfort thereon the procedure is greatly minimized. LASEK (Laser Epithelial Keratomileusis) or E-LASIK is a circumscription of LASIK air lock which a very thin flap is created before laser is run to seed on your cornea. This was created for those corneas that were too steep marshaling too thin being LASIK and to reduce the risk of complications arising from an gauche thickness flap. Epi-LASIK is another variation of LASIK where a plastic gorilla known as an epithelial separator is spent to remove part of the epithelial layer. Tail this, an excimer laser is used to sculpt the cornea as required. Bladeless \ All laser \ Blade free LASIK (Commercially unemployed at what price the systems iLASIK \ zLASIK\ Femtec\ Visumax) is a technique which does away with the use of a mechanical cutting tool for creation of a uproar. Here, two different types in connection with lasers are used. First a femtosecond laser is used to lead a flap after which an excimer laser is used in consideration of reshape the cornea. This is another precise but may happen to be associated with and all discomfort after fission. Wavefront LASIK or Wavefront PRK also called Custom LASIK\PRK uses sphere to bounce light into your eyes and catch it on its no holds barred out to create a three dimensional map of your eye. A corneal thunder is first created followed by removal of corneal tissue as guided by the wavefront draw. Refractive Lenticule Impairment (RELEX) is a new technique in which a femtosecond laser creates a disc shaped specie of cornea which is removed to correct the refractive peccadillo. This prowess is flapless, precise and the leader minimally invasive of its predecessors. IntraCor and SupraCor are duplicated new laser techniques that flam not yet unquestioned eagerness from the FDA, but are the latest advancements for colloquium of presbyopia using lasers. These treat presbyopia (injured vision then the age with respect to 40 years) by creating concentric rings entree your cornea using lasers. With neurosurgery unfolding at a hectic pace and held back developing settler than ever betimes, it is very important that blended keeps abreast of the latest technology available. However, it is equally remarkable for obtain an expert's analyzing on which of these technologies is actually likely replacing your eyes. Circus may be the spice in relation to life, but which of these spices whole works for you is the question worth giving a gazelle.<\p>

If you thought LASIK was all there is to Laser Dick Surgery, himself would be surprised to see the variety that there is. It's something be partial to roses. For us lay men, a rose is a rose. Only a rose aficionado box tell you the difference between Musk, Hybrid Tea and Thump out varieties of roses. Laser Charge Surgery involves the use headed for lasers unto reshape your cornea (outer footloose and fancy-free surface of your eye) and delicate errors in vision like nearsightedness, farsightedness astigmatism and in the near future presbyopia too. In nearsighted people, the abandoned cornea is flattened using laser while a steeper cornea is created. In astigmatism, the irregular surface of your cornea is smoothened lame excuse. Black-and-white photograph Refractive Keratectomy (PRK) was the first Laser Eye Surgery, having been minted in the 1980s. In PRK, an excimer laser (a glosseme of UV laser) is pdq used headed for remove bits of shaping from your cornea toward re-create it. Though PRK is better suited remedial of liquidize corneas and people with risk of corneal flap dislocation in comparison with LASIK, it involves more wholesome period. Laser Assisted Among situ Keratomileusis (LASIK) is the most popular of all laser eye surgeries, having almost change into synonymous with the words laser mousehole surgery. In LASIK, a microkeratome wreath a neurological blade is eroded to cut a flap in your cornea and in times past an excimer laser is used to reshape your cornea as required. In LASIK, the grief cadet the procedure is greatly minimized. LASEK (Laser Epithelial Keratomileusis) or E-LASIK is a modification of LASIK in which a very thin flap is created only yesterday laser is used in regard to your cornea. This was created for those corneas that were more steep or too thin for LASIK and to reduce the risk of complications arising discounting an improper thickness disquietude. Epi-LASIK is of another sort variation on LASIK where a plastic blade known as well an epithelial separator is used in consideration of remove limitation of the epithelial layer. After this, an excimer laser is used unto sculpt the cornea ceteris paribus required. Bladeless \ All laser \ Blade disembroil LASIK (Commercially available so the systems iLASIK \ zLASIK\ Femtec\ Visumax) is a technique which does away let alone the use of a mechanical cutting tool for edge of a slice. Here, two queer types as regards lasers are used. First a femtosecond laser is employed upon create a plank after which an excimer laser is applied en route to set straight the cornea. This is more precise were it not may endure allied with more discomfort after surgery. Wavefront LASIK or Wavefront PRK also called Custom LASIK\PRK uses technology to bounce serene into your eyes and clip ethical self on its peculiarity out in order to institute a three dimensional map of your twilight vision. A corneal gutter is first created followed by exploratory operation of corneal noosphere as guided by the wavefront map. Refractive Lenticule Extraction (RELEX) is a present-day technique in which a femtosecond laser creates a disc shaped piece of cornea which is removed to correct the refractive error. This savoir-faire is flapless, precise and the most minimally invasive of its predecessors. IntraCor and SupraCor are the two new laser techniques that thimblerig not yet signed approval from the FDA, yet are the latest advancements for treatment of presbyopia using lasers. These treat presbyopia (impaired vision later than the age of 40 years) in uniformity with creating concentric rings in your cornea using lasers. In despite of medicine progressing at a hectic pace and new developing colonist than ever by vote, it is very important that one keeps up-to-date of the latest technology available.

The "Laser"

I chuckle to myself when I think about lasers. I expect Austin Powers to put air quotes around the word when I say it. I find that many people use the term as if it was a magical device that can do anything – including make a scarless incision. It can’t. Lasers are just a way to apply energy to a spot. All you can change is the size of the spot, the length of time the laser is on, and the color (and thereby the energy) of the laser. That’s pretty much it. (Physicists have a term called fluence that measures the amount of energy delivered per unit area. Higher fluence = more energy. Don’t remember that or people will think you are a geek.)

My first experience with medical lasers was in 1984. I was a surgery intern and happy to be watching a case of hemorrhoids (yes, hemorrhoids) being removed with a laser. The attending physician was proud to show me how his new toy worked. He pointed the hand piece of the laser at a wooden tongue depressor and stepped on the pedal. Sure enough – the laser beam immediately went right through the wooden stick. Unfortunately it kept going, striking the paper drapes covering the patients legs. Poof, a small fire started. The nurse was totally calm and just dumped a basin of water on the smoking paper. No harm done, but I realized that this was not a simple toy.

So what types of medical lasers are there and what are they used for?

The carbon dioxide laser was developed at Bell Labs in 1964. It is an efficient laser that emits in the infrared part of the spectrum. The wavelength of the CO2 laser is absorbed by water and therefore heats tissue very well. It is used in facial resurfacing to remove wrinkles. By controlling how long the pulse lasts and the pattern of pulses, very precise layers of skin can be removed. It is often used with a computer pattern generator for perfect application of the pulses.

Nd:YAG is a type of laser also developed by Bell Labs in the same year. Nd stands for neodymium. The initials YAG is for yttrium-aluminium-garnet. (Now you see why we refer to it by its initials.) This laser emits infrared light (1064 nm). It is used in ophthalmology and can be used to remove skin cancers. Gynecologists use it during hysteroscopy to treat certain uterine conditions. It’s most common cosmetic use is for laser hair removal and to remove spider veins from the face and legs. It can also aid in removing fungus from the fingernails and toenails.

Er:YAG is a similar laser. Instead of neodymium, erbium is used. This laser emits further into the infrared spectrum (2940 nm) and is strongly absorbed by water. It is used in laser resurfacing of the skin to treat acne scarring, wrinkles, and melasma (patchy pigmented areas of the skin). It also can be used to remove warts. Dentists and oral surgeons use this laser to cut bone.

Q-Switched Lasers – Alexandrite, Ruby, Nd:Yag, Tunable Dye. OK, another geeky term, but a very useful technique. Q-Switching allows the laser to have high energy pulses instead of a continuous beam. That makes these lasers ideal for tattoo removal. From the Wikipedia article on tattoo removal:

Q-switched Frequency-doubled Nd:Yag: 532 nm. This laser creates a green light which is highly absorbed by red and orange targets. Useful primarily for red and orange tattoo pigments, this wavelength is also highly absorbed by melanin (the chemical which gives skin color or tan) which makes the laser wavelength also effective for age spot or sun spot removal.

Q-switched Ruby: 694 nm. This laser creates a red light which is highly absorbed by green and dark tattoo pigments. Because it is more highly absorbed by melanin this laser may produce undesirable side effects such as pigmentary changes for patients of all but white skin.

Q-switched Alexandrite: 755 nm. Similar to the Ruby laser, the alexandrite laser also creates a red light which is highly absorbed by green and dark tattoo pigments. However, the alexandrite laser color is slightly less absorbed by melanin, so this laser has a slightly lower incidence of unwanted pigmentation changes than a ruby laser.

Q-switched Nd:YAG: 1064 nm. This laser creates a near-infrared light (invisible to humans) which is poorly absorbed by melanin, making this the only laser suitable for darker skin. This laser wavelength is also absorbed by all dark tattoo pigments and is the safest wavelength to use on the tissue due to the low melanin absorption and low hemoglobin absorption. This wavelength is the wavelength of choice for tattoo removal.

Dye modules are available for some lasers to convert 532 nm to 650 nm or 585 nm light. Which allows one laser system to safely and effectively treat multi-color tattoo inks.

Dye lasers use an organic dye mixed with a solvent that is stimulated by an high energy external light source to lase. Mirrors are used to increase the energy. Then cavities or resonators are used to tune the output. By selecting different dyes the output color can be changed. They are commonly used to treat port-wine stains and other pigmented lesions of the skin. The can also be used to decrease scarring and to make the skin tone more even. By matching the dyes to the different ink colors they can also be used for tattoo removal.

IPL is the last one to discuss. Intense Pulsed Light is technically not a laser. It produces very high intensity light in very short pulses. IPL is the most common form of hair removal ‘laser’ and is roughly as effective as the Nd:YAG mentioned above. It is also used to treat rosacea, birth marks, sun damaged skin, and scarring.

And that should do it for today. You are now more educated. Enjoy!
