Q Switched ND YAG Laser

What is Q switched Nd:YAG Laser?

Nd:YAG (neodymium-doped yttrium aluminium garnet; Nd:Y,3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers.

At DISHA SKIN AND LASER INSTITUTE we use FISCHER Q Switched Nd:YAG laser This laser has a filter that emits a wavelength of 1064 nm. This 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 haemoglobin absorption. This is the wavelength of choice for tattoo removal in darker skin types.

How does Q switched Nd:YAG Laser really work in removal of Tatoos?

Tattoo consists of thousand of particles of tattoo pigment suspended in the skin. While normal human growth and healing processes will remove small foreign particles from the skin, tattoo pigment particles are permanent because they are too big to remove. Laser treatment causes the tattoo pigment particles to heat up and fragment into smaller pieces. These smaller pieces are then removed by normal body processes.

How many treatment sessions are required?

Complete laser tattoo removal requires multiple treatment sessions typically spaced at least eight weeks apart. At each session, some but not all tattoo pigment are fragmented and the body removes the fragmented pigment over the course of several weeks. The result is that the tattoo is lightened over time.

Remaining large particles of tattoo pigment are then targeted at the subsequent treatment session, causing further lightening. The number of session and the spacing of treatments depends on various parameters, including the area of the body treated and the skin color. Tattoo located at the extremeties like the ankle generally take the longest. As tattoo fade between treatments, clinicians may recommend the patients to wait many months between treatments to facilitates ink resolution and minimize unwanted side-effects.

What are the factors influencing tattoo removal?

Following variables can change the way your body will react to laser Tatto removal

Skin type: Thinner skin can scar more than thicker skin

Color: As mention dark blue or balck tattoo is easier to remove than yellow or red tatoo

Amount of ink: More ink deposited will take more time to remove

Scarring or tissue changes: A scarred tissue will have a lesser cosmetic clearance than a non scarred tissue

Is the procedure painful?

Laser tattoo removal can be slightly uncomfortable but is very tolerable in most cases. The pain is often described as hot oil on skin or a slap from a elastic band. some patient may require topical anaesthesia. A topical anaesthetic cream can be applied for 60-90 minutes prior to treatment .

What can I expect post treatment?

Immediately post treatment slight swelling, white discoloutration with or without punctuate bleeding is often observed. Minimal edema and redness on the adjacent skin usually resolves within 24 hrs. subsequently a crust appears over the entire tattoo, which sloughs off at approx. 14 days post treatment. Post operative care include topical application of antibiotic ointment and a non-occlusive dressing. Fading of the tattoo will be noted over 8 weeks and retreatment energy levels can be taloired depending on the clinical response observed.

Are there any side effects?

Transient pigmentary changes may occur that resolves in 6-12 months, rarely permanent.

Darkening of skin is related to the skin type. Skin types IV, V and VI are more prone to darkening.

Transient textural changes are occasionally noted but often resolve within a few months.

Rarely scarring can occur.

Additionally, if a patient forms a blister or crust post treatment, it is imperative that they do not manipulate this secondary skin changes.

Local allergic response to tattoo pigment- like redness, swelling, inflammation can occur.

Rare adverse effects include hypopigmentation(white spots), hyperpigmentation(dark spots) burns, scars, paradoxical darkening of tattoo
