Introduction
It has been estimated that up to a quarter of young to middleaged adults have at least one tattoo. As more tattoos are being acquired, increasing numbers of people are also seeking their removal. The number of tattoo removal procedures is still growing.
The motivation for tattoo removal includes new jobs or careers, the need to portray a certain image at work or in new social circles, and new, negative feelings towards old tattoos or sometimes tattoo went very bad [1]. Tattoos are created by the introduction of exogenous pigment into the dermal skin layer and be divided into professional, amateur, cosmetic, traumatic, or medical tattoos. Professional tattoos are applied with a tattoo machine into the deeper layer of the dermis and are permanent in nature.
Cosmetic tattoos are often referred to as permanent makeup, are becoming to be more popular. Permanent eyeliners, eyebrows, and lip liners are commonly applied using the process of sparse micro-pigmentation to save time and enhance facial features such DOI: 10.26717/BJSTR.2021.34.005504 26460 as lips, eyelids, eyebrows. Inks used usually contains red, brown, or flesh-like pigments containing iron dioxide or titanium dioxide, that is why they ate difficult to remove. They may turn black after Q-switched (QS) laser treatment. Chemical reduction of ferric to ferrous oxide is thought to be responsible for such a phenomenon.
Such paradoxical darkening has been successfully treated with further QS laser treatments, sometimes requiring up to 20 sessions.
Unfortunately, laser tattoo removal is generally more costly, more painful, and takes more time and more patience to have it done.
Q-switched (QS) lasers are the gold standard in tattoo removal.
As per the Theory of Selective Thermolysis, the laser pulse duration is critical and should be equal or shorter than the Thermal Relaxation Time (TRT) of the target chromophore. Tattoo ink granules measure 0.1μm and their TRT has been estimated to 10ns. QS laser is characterized by the release of a high amount of energy in an extremely short time -Nanoseconds (ns) or Picoseconds (ps). The violent and rapid thermal expansion induced by light absorption generates shock waves audible as a popping sound with each laser pulse with potentially localized cavitation leading to vacuoles [2].
The administration of energy in such a short pulse leads to a rapid thermal expansion of the target, that is, subsequently fragmented by the release of an acoustic wave that leads to destruction and ''cutting'' tattoo pigment. The disintegration of pigments into smaller granules allows macrophages to phagocyte fragments and to carry them away via the lymphatic system. Phagocytosis is subsequently triggered and the tattoo fragments are packaged for lymphatic drainage and further scavenged by dermal macrophages, fibroblasts, and mast cells, leading to a lightening of the tattoo.
The pigment treated this way gradually becomes shallow until it disappears, while no injured trace will be left on the peripheral tissues making the treatment selective and safe.
On laser impact, the immediate flash of white light from the tattoo is followed by epidermal whitening and slight edema.
Immediate tissue whitening is a sign of rapid, localized heating with steam formation, resulting in dermal and epidermal vacuolization.
Some pinpoint bleeding may be observed (most likely represent indirect vascular injury from the photo-acoustic waves [3].
The immediate whitening phenomenon is a good marker for melanosome destruction and resolves within 10-20 minutes approximately. It should be considered as a treatment end-point and if not observed, it is likely that the laser exposure dose is not sufficient. Frosting made by application of Q switched laser prevents entrance of laser light within the dermis [4]. In 2012 R20 method protocol was proposed by Kossida [5], in which up to 4 passes of laser are allowed, with subsequently 20 minutes waiting between the passes. It was hypothesized that after the subsidence of frosting in the event that we deliver laser, at that point it can enter more profound within the dermis hence focusing on more dermal ink. It can also fragment the ink particle into smaller pieces thus allowing faster clearance of ink by macrophages. It is more effective than the traditional method. The number of sessions required for tattoo removal is greatly reduced thus decreasing the number of visits to the clinic and increasing patient compliance. However high risk of darker phototypes patients scarring was observed.
Cosmetic tattoos show many peculiar characteristics, so their removal requires specific considerations. Permanent makeup inks are different from regular tattoo inks as they often contain a higher percentage of inorganic matter and oxides-used for their reflective purposes. Some of the semi-permanent makeup is resistant.
As suggested by Cannarozzo G, et al. [6], a single passage with fractional ablative Er:Yag laser was used as the first pass, to induce an ink clearing and to reduce the possibility of scar formation [6][7][8]. Perfluorocarbons (PFCs) are micron-sized non-toxic, chemically, and biologically inert compounds with unique physical properties that enable their use in a wide range of medical applications. It helps to heal wounds, possesses a bubbling effect. It is a stable, heavy liquid and has no flashpoint. Perfluorocarbons have potential additional benefits including reduced collateral thermal tissue injury due to tissue compression owing to its high specific gravity [9,10]. Absorption via the epidermis of topical products is limited by the barrier role of the skin. Laser-Assisted Drug Delivery (LADD) which, due to its ability to produce microscopic ablated channels, often uses ablative fractional lasers to enhance drugs absorption.
It is necessary to adapt the parameters of LADD to the patient, the skin condition and its location, and the drug [11]. During a laser tattoo removal procedure, when ink granules undergo a rapid temperature increase, which subsequently heats the surrounding PFC liquid while simultaneously producing an ultrasound pressure wave. The total treatment time is thus reduced from 80 min to 5 min.   Also it is time-saving and cost effective.
