1.2 Applications
The WON COSJET ATR S laser system is a flash lamp pumped, Q-Switched
Nd:YAG(Neodymium-doped Yttrium Aluminum Garnet) laser is near infrared (1064 nm) and
visible (532 nm) pulsed laser output energy are used in these applications. This beam is directed
to the treatment zone by means of the Articulated arm and specially designed handpiece. When
the laser beam contacts human tissue, the energy in the beam is absorbed surrounding skin
structures. The physician can optimize the effect for different applications by controlling the
energy of the laser pulse and the spot size of the treatment beam.
1.2.1 Side effect
Skin lightening (depigmentation): Some dark skinned individuals can develop fading of the skin
color. This complication is temporary and usually resolves within 10-14 weeks. However, there
are times when the complication is permanent.
Skin darkening (hyperpigmentation): In fair skinned people, lasers can sometimes cause
darkening of the skin. Over time this fades and recovers; but in some cases a bleaching agent has
to be used to erase the dark color.
Infections : Sometimes an infection can occur at the site of the tattoo removal. The infection may
be superficial and resolves but in some cases, deep skin infections can occur and result in a scar.
Skin Texture : After laser treatment, most individuals will have a rough skin texture. The skin
will feel like it has been scraped. These changes are transient and usually resolve in 1-3 months.
Thick skin usually resolves better than thin skin. The facial skin is more sensitive to texture
changes than skin elsewhere on the body.
Allergic reactions : Rarely when the laser disrupts the ink particles some individuals may have an
allergic type reaction. It is not known why the reaction occurs and to what ink. The skin usually
becomes red, dry and it itchy. Application of topical corticosteroids will suffice.
Ink darkening : When the laser is applied on cosmetic tattoos, it can worsen or darken the color.
This is most likely felt to be due to the heat of the laser reacting with the cosmetic chemicals. The
changes can be permanent. So before a cosmetic tattoo is treated, a brief test is done to look at the
response. Many an individual has had permanent tattooing of their eye liners.
Sun burn : After every laser procedure, a sunburn effect occurs. The skin appears red and fiery in
some cases. This is a normal and transient- it does resolve within a few weeks. Besides keeping
the area clean, there is no need to apply any ointments or creams, except the sunscreen
