Hello Interloper!

Due to the depth of treatment required to remove tattoo inks, the treatment is generally considered to be painful, although this will vary from person to person due to different tolerances to pain. A stinging or burning sensation will be noticed during the procedure, and the area treated may feel hot for some time after treatment. Your practitioner can advise on ways to alleviate any pain and discomfort during treatment with topical anaesthetics and cooling devices.
During treatment, most patients will experience small white dots which appear on the skin for several minutes after each firing of the laser – this is only water, vaporised by the heated tattoo pigment, and fades within a few minutes. After the treatment, minor bleeding may occur, with skin redness, swelling and oozing, plus blistering appearing over the treated area. The treated area may also feel very tender to the touch. This will fade over a few days. Once any blistering, crusting or scabs have resolved, the area of skin over the tattoo will look shiny for a number of weeks. It is vital that the skin is well looked after immediately after treatment. The treatment site should be considered as a minor burn and should not be picked at, and blisters should not be popped. There is a risk of infection if the area is not properly looked after.
Once the skin has returned to normal, generally after 4 – 6 weeks, then repeat treatments can be performed.
Post-treatment risks or side effects include:
Hyperpigmentation – patches of darkened skin, especially on people with darker skin-types. This condition usually resolves on its own, although skin products are available to help even out disrupted skin tones
Hypopigmentation - patches of pale skin colouring or loss of natural skin colour. As the laser treatment can also target the natural skin pigment colour or melanin in your skin as well as the colour of the tattoo inks, this can leave the treated area with a somewhat ‘bleached’ look following treatment. This will usually recover to some extent but it can take months and even years to do so. In some cases, the skin where the tattoo was treated may never match exactly with the surrounding area. This risk is increased with darker skin colours and the number of treatment sessions required to successfully remove the tattoo pigments.
Scarring - as these lasers do not heat up the surrounding tissue to a great degree, the risk of scarring following tattoo removal is considered to be very low. In the rare cases where scarring may occur, this is generally due to either a history of scarring (some people scar very easily) or poor treatment site healing, generally caused by the patient picking at scabs. Extreme multiples of treatment (30+), as a result, for example of a very resistant green pigment within the tattoo also increase the risk of scarring although in all cases, scarring risks can be alleviated by the use of silicon scar-reduction gel.
