Skin Rejuvenation Tattoo Removal Q-Switch ND YAG Laser Machine
Skin Rejuvenation Tattoo Removal Q-Switch ND YAG Laser Machine
With the overwhelming popularity of tattoos over the last ten years, the market for effective removal has exploded. Tattoos are created by injecting colored pigment into small deep holes made in the skin. Regardless of whether a tattoo artist or an untrained individual injects the pigment, the marks or designs are relatively permanent. When people subsequently want their tattoos removed, most physicians today consider laser surgery one of the best methods. The Q-switched Nd:YAG is the most frequently used laser for tattoo removal. During treatment, pulses of light from the laser are directed onto the tattoo, breaking up the tattoo pigment. Over the next several weeks the body's macrophages remove the treated pigmented areas.
Technology in use
Tattoo ink and natural pigmentation like melanin absorb short pulse duration/high peak energy Q-switched pulses so quickly that they create a photo-acoustic effect within the pigment clusters. This effect breaks down the ink into much smaller particles that can be more easily removed by the body's natural filtering system.
Key advantages for physicians
Easy to administer, simple to switch between wavelengths
Also able to treat dermal pigmented lesions such as nevus of Ota
Key advantages for patients
Minimal risk of side effects
Effective treatment for dark tattoo inks (black, blue and green)
Dramatic results after several treatments
Laser tattoo removal FAQ:
1.What is Nd:YAG laser?
Nd:YAG (neodymium-doped yttrium aluminium garnet) is a crystal that is used as a
laser medium for solid-state lasers.
The triply ionised neodymium [Nd(III)] dopant (ie a substance added in minute amounts to another pure substance to alter its conductivity), typically replaces a small fraction of the yttrium ions in the host crystal structure, since the two ions are of similar size.
The neodymium ion provides the laser activity in the crystal.
Nd:YAG laser has a wave length of 1064 nm and has the capability to reach deeper layers of skin tissue than other types of lasers.In Q-switched mode, Nd:YAG produces 2 wavelengths, one in the infrared range (1064 nm) and a second beam of 532 nm wavelength which is useful for superficial
skin lesions. Q-switching refers to the technique of making the laser produce a high intensity beam in very short pulses
2.How does Nd:YAG laser work?
Lasers work by emitting a wavelength of high energy light, which when focused on
a certain skin condition will create heat and destroy diseased cells.
3.What does the laser procedure involve?
It is important that the correct diagnosis has been made by the clinician prior
to treatment, particularly when pigmented lesions are targeted, to avoid mistreatment of skin cancer such as melanoma.
1).The patient must wear eye protection (an opaque covering or goggles) throughout
the treatment session.
2).Treatment consists of placing a hand piece against the surface of the skin and
activating the laser. Many patients describe each pulse feeling like the snapping of a rubber band against the skin.
3).Topical anaesthetic may be applied to the area but is not usually necessary.
4).Skin surface cooling is applied during all hair removal procedures. Some lasers
have built-in cooling devices.
5).Immediately following treatment, an ice pack may be applied to soothe the treated area.
6).Care should be taken in the first few days following treatment to avoid scrubbing the area, and/or use of abrasive skin cleansers.
7).A bandage or patch may help to prevent abrasion of the treated area.
8).During the course of treatment patients should protect the area from sun
exposure to reduce the risk of postinflammatory pigmentation.
4.Are there any side effects from Nd:YAG laser treatment?
Side effects from Nd:YAG laser treatment are usually minor and may include:
1).Pain during treatment (reduced by contact cooling and if necessary, topical anaesthetic)
2).Redness, swelling and itching immediately after the procedure that may last a few days after treatment
3).Rarely, skin pigment may absorb too much light energy and blistering can occur
(this settles by itself)
4).hanges in skin pigmentation. Sometimes the pigment cells (melanocytes) can be
damaged, leaving darker (hyperpigmentation) or paler (hypopigmentation) patches of skin. Generally, cosmetic lasers will work better on people with lighter rather than darker skin tones
5).Bruising affects up to 10% of patients. It usually fades on its own
6).Bacterial infection. Antibiotics may be prescribed to treat or to prevent wound
5.How many laser treatments can I expect?
Treatment time depends on the form, size and location of the lesions as well as the skin type.
Small red vessels can usually be removed in only 1 to 3 sessions.
Several sessions may be necessary to remove bigger veins and spider veins.
In general, patients have 2 to 6 treatments, approximately every 4 to 6 weeks.
Patients with darker skin types may require more treatments.
The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment for tattoo removal.
Multiple sessions (5 to 20 sessions) spaced at least 7 weeks apart may be required to attain favourable results.
The following skin disorders can be treated with Nd:YAG laser beams.
ND:YAG can be used to remove spider and thread veins in the face (cheek,temporal region, nasal dorsum, forehead) and legs.
Some vascular birthmarks (capillary vascular malformations)Varicose veins in the leg Facial veins (telangiectasis)
Haemangiomas (vascular tumours) in the face and around the mouth
Nd:YAG laser can be used to remove brown age spots (solar lentigines), freckles,naevus of Ota, naevus of Ito, mongolian spots, Hori naevus and cafe-au-lait-
macules.Light pulses target melanin at variable depth on or in the skin.
Blue, grey and black tattoos can be removed with a Q-switched Nd:YAG laser (1064 nm wavelength).
The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment.
Laser treatment involves the selective destruction of ink molecules that are then absorbed by macrophages and eliminated.
Other uses of Nd:YAG laser
Nd:YAG lasers have also be used to improve wrinkles in photo-aged skin.
