Laser lights have been used by dermatologists for tattoo removal through photothermal interactions. However, most clinical studies used a visual scoring method to evaluate the tattoo removal process less objectively, leading to unnecessary treatments. This study aimed to develop a simple and quantitative imaging method to monitor the degree of tattoo removal in in vivo skin models. Sprague Dawley rat models were tattooed with four different concentrations of black inks. Laser treatment was performed weekly on the tattoos using a wavelength of 755 nm over six weeks. Images of non-treated and treated samples were captured using the same method after each treatment. The intensities of the tattoos were measured to estimate the contrast for quantitative comparison. The results demonstrated that the proposed monitoring method quantified the variations in tattoo contrast after the laser treatment. Histological analysis validated the significant removal of tattoo inks, no thermal injury to adjacent tissue, and uniform remodeling of epidermal and dermal layers after multiple treatments. This study demonstrated the potential of the quantitative monitoring technique in assessing the degree of clearance level objectively during laser treatments in clinics.

“…Parallel to the worldwide popularity of tattoos, Q‐switched yttrium aluminium garnet (YAG) laser has become the preferred method for tattoo removal due to the very short impulse that limits the thermal damage of the treated skin . Picosecond lasers were recently introduced aiming at further reduction of thermal damage of the skin and better tattoo clearance . However, advantages and cost‐effectiveness of new picosecond lasers remain to be documented.…”

Applications of picosecond lasers beyond tattoos: pigment reduction and tissue remodeling

We read the recent review regarding the use of picosecond lasers for tattoo removal with interest. Whilst the evidence underlying tattoo treatment is equivocal, there are promising results for other indications [1] for which picosecond laser use may be better tolerated or more effective.The ultra-short pulse duration of the picosecond laser imparts a predominantly photo-acoustic effect on the tissue and has fewer side effects (such as dyspigmentation, scarring) and shorter postprocedural downtime. As such, picosecond lasers could become more widely used by clinicians than longer-established laser modalities, with the added benefit of less downtime and higher efficacy.To date, there is evidence of use of picosecond lasers in both pigment clearance [2,3] and tissue remodeling with cases published showing efficacy in the appearance of nevus of Ota [4], minocycline-induced pigmentation [5], photo-aging [6] and acne scars [7].Picosecond lasers used in all of the above conditions lead to improvement of dyspigmentation and/or textural change, with tolerable side effects of mild transient erythema and oedema [1].The sample sizes of the studies [4][5][6][7][8] were however small, ranging from 3 to 20 patients with an average follow-up of 3 months.Practitioners should be aware of the range of uses of picosecond lasers beyond tattoo removal in order to ascertain their full potential; larger randomized control trials and split face studies could further inform future practice.
