Abstract:
Q-switched (QS) Nd: YAG lasers are frequently utilised light sources for tattoo removal due to their precise micro- confined photo-acoustic interaction with exogenous and endogenous pigments. In order to achieve optimal results, several treatment sessions are usually required. However, the number of sessions depend on tattoo size, design com- plexity, pigment quantity within dermal layers, and anatomical location. Higher energy settings have often been used to reduce treatment sessions to a minimum however, this approach may lead to possible post-laser skin complica- tions such as pathological wound healing. This case report highlights the importance of recognizing early stages of pathological wound healing encountered after high fluence 1064 nm QS laser tattoo removal. Early implementation of a proportional wound care strategy with anti-neoangiogenic and anti-inflammatory properties through the uncon- ventional use of potent topical steroids applied in a pulsed fashion resulted in positive control of the tissue repair processes. This approach led to effective wound healing re-modulation achieving near normal skin remodelling and optimal tissue healing which in turn, permitted the completion of necessary QS tattoo removal sessions to accomplish successful and safe tattoo fading whilst maintaining overall patient satisfaction.
