Letter Case Reports
Nodular skin reactions in eyebrow permanent makeup: two case reports and an infection by Mycobacterium haemophilum.
Permanent makeup is becoming more and more popular. The procedures, however, bear some medical risks. ⋯ Adverse reactions after permanent makeup need a medical evaluation to identify health risks and initiate early treatment.

Randomized Controlled Trial
Effects of lavender olfactory input on cosmetic procedures.
To evaluate the effects of the aroma of essential oil of lavender against placebo on subjects' pain perceptions and levels of anxiety when undergoing elective cosmetic facial injections of botulinum toxin type A (BOTOX(®) COSMETIC) for the correction of glabellar wrinkles. ⋯ Although essential oil of lavender did not have an effect on the subjects' perception of pain during a facial injection, subjects showed significant increases in parasympathetic activity when exposed to the lavender aroma. Lavender aromatherapy has the potential to ease anxiety in patients undergoing minimally invasive facial cosmetic procedures.

Review
The evidence for reducing the pain of administration of local anesthesia and cosmetic injectables.
Administration of injections, whether local anesthetic or cosmetic injectable, can result in significant distress and discomfort to patients. This review explores factors that can alleviate anxiety and pain associated with injections including cosmetic injectables. We highlight that many techniques used to reduce pain have only been reported based on anecdotal evidence and small series. The techniques that have been reported to reduce pain, by randomized controlled trials, include pretreatment with topical local anesthetic agents and combined cosmetic injectables with local anesthetics.

Letter Case Reports
Paradoxical darkening and removal of pink tattoo ink.
It is widely accepted that Q-switched lasers are the gold-standard treatment for the resolution of unwanted tattoo ink. Although much safer than other tattoo removal modalities, the treatment of tattoo ink with Q-switched devices may be associated with long-term adverse effects including undesired pigmentary alterations such as tattoo ink darkening. Darkening of tattoo ink is most often reported in cosmetic, flesh-toned, white, peach, and pink tattoos. In this paper, we briefly review a case of pink tattoo ink that initially darkened paradoxically but eventually resolved with continued Q-switched laser treatments.

Randomized Controlled Trial Multicenter Study
A multi-center, double-blind, randomized controlled study of the safety and effectiveness of Juvéderm injectable gel with and without lidocaine.
Pain is a common patient complaint during dermal filler injections. The primary objective of this study was to compare a new formulation of Juvéderm((R)) injectable gel with lidocaine (denoted as JUV + L) to commercially-available Juvéderm((R)) injectable gel without lidocaine (denoted as JUV) with respect to procedural pain scores in subjects desiring nasolabial fold (NLF) correction. ⋯ The dermal filler formulated with lidocaine is effective in reducing procedural pain during correction of facial wrinkles and folds while maintaining a similar safety and effectiveness profile to the filler without lidocaine.
