Safety Issues Regarding Laser Hair Removal

Safety issues regarding laser hair removal relate to both clients and technicians. These safety issues are very different than those involving other forms of epilation. There are no concerns of drawing blood, contaminating probes, or risking infection. However, there are concerns regarding burns and eye safety. Several organizations have laid down guidelines to ensure the safety of both the clients and technicians. These organizations include The Occupational Safety and Health Administration, The American National Standards Institute, The Food and Drug Administration, The Center for Devices and Radiological Health, and The Society for Clinical and Medical Hair Removal.

All laser hair removal devices in the United States are subject to very strict mandatory performance standards. They also must meet the federal laser product performance standard, which includes specifying their safety features, both for the benefit of the patient and technician.

It is best to purchase new laser hair removal equipment. If used equipment must be purchased, it should only be bought from a qualified distributor with the assurance that it has been thoroughly checked and serviced. The equipment should also be guaranteed..

The room that is used for laser hair removal can be used for other treatments. However, it must be set up in accordance with the strict guidelines that are associated with the use of laser equipment. Setting up the room the proper way is usually done by the equipment distributor or the manufacturer.

The laser hair removal room should have a door that can be locked during treatment. There should be a warning light outside the door to let others know that treatment is being done and they should not enter. There should be protective eyewear, outside of the door for people who may need to enter during a treatment. They should not be any windows in the room, however if there are windows they should be blacked out with protective coverings. It is very important to that the electrical outlet has its own circuit breaker. It also must be grounded, and have the proper amperage and voltage. The room should not have any mirrors or reflective surfaces in it.

Laser hair removal equipment should be on a flat surface and have plenty of ventilation around it. This equipment should only be serviced and calibrated according to the manufacturer’s guidelines for that particular device. It should be regularly cleaned of any carbon buildup that may occur. When the laser equipment is not in use the key should be removed.

It is important that the operator of the laser hair removal device be well trained and qualified. This training should be in all areas including histology and client care. The technician should not wear any reflective clothing or jewelry. The technician, along with any other person in the room, is required to wear ANSI approved protected our eyewear in order to avoid laser blindness.

The client should receive a thorough and detailed consultation, pre and post care instructions, and a patch test before the laser hair removal treatment begins. It is also important that the client understands the benefits and risks of the treatment. During the laser hair removal process the client should wear ANSI approved protective eyewear and be instructed to keep the eyewear on throughout the treatment.

Tray-Based Teeth Whitening: Extending Professionals Touch

Out of curiosity, have you ever asked the question why teeth get dark? Or have you even pondered on the possible answers to this simple query?

Tooth discoloration should not be taken lightly though the case should really lighten to brighten up a smile.

There are many reasons why teeth get stained. The most typical reasons vary from factors written below:

1.heredity
2.consumption of staining substances (such as tea, coffee, and colas)
3.excessive fluoride and use of abrasives (which only expose dentin and causes severe discoloration)*
4.tetracycline (antibiotic) staining
5.old fillings
6.aging

Toothpastes that have whitening agents can minimize the stain that is on the surface of the teeth. The case is also coined by dentists as extrinsic staining. However, professional dental cleanings and whitening toothpastes will not change the intrinsic staining of the teeth, if used appropriately. This is the main reason why tooth bleaching or tooth whitening is so popular.

Normally, teeth whitening remedies are categorized into two:

1.Professional whitening systems

This is usually performed by dentists using whitening gels and lasers to activate the solution. This is normally done inside a dental clinic.

2.Home-based teeth whitening remedy

This could either be done in-between appointments of professional treatments using whitening kits and tray-based whitening techniques or are just home-made remedies from kitchen and medicine items. These applications are usually done at home and according to the frequency suggested by dentists and/or by a products instructions.

Just how is tray-based teeth whitening technique employed to the patient? Read on the following four-step procedure:

1.A whitening gel is poured all over a tray that just fits over the teeth of the patient.
2.The active ingredient inside the gel, carbamide peroxide will be broken down sp that oxygen can enter the enamel to bleach the discolored areas.
3.By this, the physical structure of each tooth is not actually transformed. Crowns, fillings, and Bonding will not lighten but the colored substances will.
4.Casts or impressions of the tray are customized by dentists. The accuracy of the trays is critical to the treatment

Below are follow-up questions most patients are curious about tray teeth whitening method.

How safe is the method?

Most dentists agree that tray bleaching or whitening is relatively safe, fast, provides easy ways to lighten teeth between two and five shades in a matter of few days.

How is this different from other professional whitening systems?

Below is a list of some professional whitening products dentists in choosing items for their professional whitening system. The kind of bleaching laser or light is enclosed in parentheses.

1.BriteSmile (gas plasma light/light emitting diode)
2.LaserSmile (a Biolase laser)
3.LumaArch (halogen light)
4.Rembrandt Sapphire (plasma arc light)
5.Zoom! (metal halide light)

Generally, laser treatment is done by applying a 35% Hydrogen Peroxide gel-based solution on the teeth of the patient. After applying the solution on the surface of the teeth, a light is held several inches away from the patients mouth to activate the peroxide component of the gel. There are manufacturers and dentists who advertise that this method works better than tray whitening method. There are no actual data completed to support their claims.

Actually, after a year of usual lifestyle habits (drinking tea, colas, coffee, smoking, etc.) treatments using laser-accompanied whitening gel are disregarded. This will cost you another $ 500 or more to have the same treatment again.

However, with the custom-made mouthpieces, you can have your usual lifestyle habits for a year and perform touch-ups one day roughly alternately every 3-6 months to take off the new stain inexpensively.

Necessary Care after Laser Hair Removal

Laser hair removal, although a simple process, does require proper care of the skin in the area that was treated. Generally there is little recovery time needed regarding laser hair removal procedures. People can usually return to normal activities immediately after treatment. However, it is important to take the time to follow the recommended guidelines for aftercare in order to protect against any chance of a complication and to reduce any discomfort that may be experienced.

Following laser hair removal treatment, it is not uncommon for the skin to be slightly swollen and red in the treated area. Some people describe it as feeling like a mild sunburn, with slight puffiness and irritation. Placing a cooling preparation such as a cold compress, cold pack, or aloe vera, on the affected area will ease the temporary mild burning sensation. Some people experience this burning sensation for only a few hours, while others may feel it for a day or two. This is the time it takes for the skin to return completely to its normal state.

It is important to apply a total sunblock to the area that was treated with laser hair removal if it is going to be exposed to sunlight. A sunblock with an SFP of 30 or higher should be applied. Irritation and a burning sensation of the treated areas can result from even the slightest exposure to the sun. Sunlight should be avoided for three weeks following laser hair removal. This will prevent hyperpigmentation from occurring.

Moisturizing creams can also have a beneficial effect on the treated areas and help to prevent tissue crusting or scabbing. These creams can be bought over the counter or be prescribed by your practitioner. It usually is not necessary to use antibacterial cream. In fact, antibacterial creams might cause drying of the skin in the area that was treated with laser hair removal. Healthy skin is important for successful laser treatments and moisturizing every day will help to keep your skin that way.

As long as the skin is not broken, it is safe to apply makeup to the areas of the skin that have undergone laser hair removal treatments. The makeup used should be new and applied with clean fingers or a new clean sponge. Make of also helps to act as an additional sunblock.

Following a laser hair removal treatment, it is best to take warm, quick showers. It is best to use a gentle cleanser and avoid harsh soaps that may dry the skin. If any area of the body other than the face as has been treated, hot baths should be avoided for a couple of days.
The area of treatment should not be shaved for four or five days. After that time, it is okay to begin shaving again. Tweezing, waxing, plucking, and bleaching should not be done at all during, or in between, laser hair removal treatments.

If any blistering occurs, immediately apply a topical antibiotic cream or ointment and cover it with a non-adhering dressing. Immediately notify the laser technician or your physician.

After a few days, you will usually notice the hair that was treated by laser hair removal begins to shed. This should be expected and is a normal part of the treatment and recovery.

Laser Hair Removal Devices

There are several different types of laser hair removal devices available today. These are alexandrite lasers, diode lasers, ruby lasers, and NeoDymium Yttrium Aluminum Garnets, which is commonly referred to as Nd:YAGs.

Alexandrite lasers became available for use in laser hair removal in 1997 when they were cleared by the FDA. Alexandrite lasers produce light beams in the red spectrum of visible light.
Their wavelength is 755 nanometers which is very effective but only safe on light skin. Generally, alexandrite lasers are considered long pulsed and because of this produce greater depth penetration. Five different types of the alexandrite laser are available. These include the Apogee, GentleLase, Epicare, Epitouch Alex, and Ultrawave II-III.

The FDA also cleared diode lasers for use in 1997 as an effective method of permanent hair reduction. Diode lasers produce a wavelength of 800 nanometers with pulse widths of 5-400 milliseconds. This type of laser has proved successful in the treatment of ingrown eyelashes and works very well on dark hair. The Light SheerXC is a diode laser that is extremely powerful. Other diode lasers include EpiStar, Apex-800, Iridex, and Mediostar.

Ruby lasers were also cleared by the FDA for laser hair removal in 1997, however, they did not prove as effective. Clinical research showed that the laser damage did not extend far enough down into the hair shafts to result in permanent laser hair removal. Originally there were five types of ruby lasers, of which only two are still available for commercial use. A Ruby lasers operate on a shorter wavelength system of only 694 nanometers.

NeoDymium Yttrium Aluminum Garnets have a longer wavelength which makes them more effective for longer term, and according to some people, even permanent laser hair removal. There are two types of Nd:YAGs lasers. These are the Q switched and the long pulse. All Nd:YAGs produce a wavelength of 1064 nanometers. The Q, switched NeoDymium Yttrium Aluminum Garnets has a very short pulse of about one nanosecond. Long pulse NeoDymium Yttrium Aluminum Garnets have a pulse of about a millisecond and can be used on all skin types.

The pulse duration, or pulse width, of lasers used for hair removal is the timing of the light energy. It is usually measured in milliseconds. Most lasers used for hair removal have a maximum pulse duration in the 20 to 40 millisecond range. Longer pulse widths are generally considered more effective and produce fewer side effects.

Each type of laser produces a specific spot size which is measured in millimeters. The spot size is the size, or width, of the beam of light at the laser sends out. A spot size of seven to 10 mm is considered acceptable for laser hair removal.

Most lasers have three main parts, an energy source, and active medium, and an optical cavity, also known as a resonator. The energy source is a device that supplies energy to the active medium. Laser hair removal devices use electricity as their energy source. The element of the active medium contains atoms that can both absorb and store the energy. The optical cavity is the part of the laser that contains the active medium. Lasers are defined by the elements they use.
