[Forum: dermopigmentation or medical tattooing. Dermopigmentation with an esthetic aim. Apropos of 420 cases].

420 cases of chromatic skin corrections for medical or aesthetic reasons have been documented over the last 1-5 years. The author analyses cases based on local anatomy classification, so that good and poor results of the technique are clearly revealed. Results are then regrouped in a synthetic study, without distinction of anatomical area. This synthesis establishes a check list of defects inherent in the technique: pain or discomfort, poor smoothing-out of skin defects, far from natural chromatic variations of the skin, dull lacklustre colours, short-lasting pigmentation, and chromatic instability of dyes. All these pigmentations were performed using basic techniques and medical pigments. The author suggests that in the future these defects should be corrected by: more systematic use of dyes used by tattoo artists, addition of a gloss in the dyes, transparent technique, anaesthetic skin cream.
