Title:
High speed ink aggregates are ejected from tattoos during Q‐switched Nd:YAG laser treatments.


Abstract:
IntroductionDark material has been observed embedded within glass slides following Q‐switched Nd:YAG laser treatment of tattoos. It appears that these fragments are ejected at high speed from the skin during the treatment.


Industry Significance Rating:
Medium - Industry wide monitoring is recommended.

Title:
Unveiling skin macrophage dynamics explains both tattoo persistence and strenuous removal.


Abstract:
The authors: "describe a new mouse model that exploits the pattern of expression of the high-affinity IgG receptor (CD64) and allows diphtheria toxin (DT)-mediated ablation of tissue-resident macrophages and monocyte-derived cells. We found that the myeloid cells of the ear skin dermis are dominated by DT-sensitive, melanin-laden cells that have been missed in previous studies and correspond to macrophages that have ingested melanosomes from neighboring melanocytes. Those cells have been referred to as melanophages in humans. We also identified melanophages in melanocy ...

Title:
Identification of organic pigments in tattoo inks and permanent make-up using laser desorption ionisation mass spectrometry.


Abstract:
Nowadays, about 12% of the European and 20% of the US population are tattooed. Rising concerns regarding consumer safety, led to legal restrictions on tattoo and permanent make-up (PMU) inks. Restrictions also include bans on certain colourants. Both ink types use organic pigments for colour-giving, plus inorganic pigments for white and black and colour tones. Pigments are only sparingly soluble in common solvents and occur as suspended particles in the ink matrix. Their detection and identification therefore pose a major challenge for ...

Title:

Microbiological survey of commercial tattoo and permanent makeup inks available in the United States



Abstract:
AIMS: Tattooing and use of permanent makeup (PMU) has dramatically increased over the last decade, with a concomitant increase in ink-related infections. The aim of this study was to determine whether microorganisms are present, and if so, the number and their identification, in the commercial tattoo and PMU inks available in the United States. METHODS AND RESULTS: We surveyed 85 unopened tattoo and PMU inks, purchased from 13 companies. We incubated 100 μL of ink samples on trypticase soy agar plates for bacterial growth, 7H10 Middlebrook medium for ...
