es for epidural procedures of 2%, or 0.2% annually, from 2009 to 2018. However, prior to inflation, the increases were noted at 14.6% and 1.5%. Inflation-adjusted costs per patient, per visit, and per procedure also declined. The proportion of Medicare patients per 100,000 receiving epidural procedures decreased 9.1%, or 1.1% annually. However, assessment of individual procedures showed higher costs for transforaminal epidural procedures compared to lumbar interlaminar and caudal epidural procedures. There is an increasing rise of cosmetic injectables. We sought to understand the manufacturing, quality control process, and needle selection of hypodermic needles for fillers. To understand the process of manufacturing and quality control of hypodermic needles and the relevance to an aesthetic clinician. We conducted a search of the internet and contacted medical device companies to understand the manufacturing process. We then collaborated with the Executive director of global pharmaceutical technology from Abbvie as well as the packaging and device engineer at Galderma and summarized our findings. Microtubule Associated inhibitor Finally, we reviewed the literature and summarized existing recommendations on techniques to minimize pain related to injection. Hypodermic needles undergo an extensive manufacturing and regulatory process. Many considerations are taken into account in needle manufacturing as well as the selection process with commercially available hyaluronic acid filler products. Needle manufacturers are held to universal standards though the International Organization for Standardization (ISO). Filler companies perform their own testing to evaluate suitability of needles for their product including leakage force, penetration force, extrusion force, etc. Finally, parameters such as needle length, needle diameter, and wall thickness are considered for selection of needle/hub with individual filler viscosity. There is extensive consideration that goes into needle manufacturing, quality control, and optimization for hyaluronic acid filler. Understanding the technical process helps inform the clinician and guide patient care for maximum comfort. J Drugs Dermatol. 2021;20(1)44-48. doi10.36849/JDD.5591.

Treatment of upper facial lines is a common aesthetic practice; however, there is limited information on systematic tailored approaches for the treatment of forehead wrinkles using botulinum toxin A. To describe the safety and efficacy of the ONE21 technique using incobotulinumtoxinA (INCO) for the treatment of forehead wrinkles. Single-center, retrospective study with 86 females presenting a baseline Merz Aesthetic Scale (MAS) score &ge;2 for dynamic forehead lines who had been treated with INCO using the ONE21 technique. Assessment was performed by two independent blinded raters using MAS for forehead lines (dynamic and at rest), and eyebrow positioning, based on standardized pictures taken before (baseline) and 4 (&plusmn;2) weeks after treatment injection. The primary outcome was the percentage of subjects with a MAS improvement &ge;2 points for dynamic forehead lines at week 4 (&plusmn;2). Secondary outcomes were MAS scores for resting forehead lines and for eyebrow positioning. The mean age was 46.2 years, and mean total dose of INCO, 20.3 U. Most (97.7%) subjects had a MAS improvement of &ge;2 points for dynamic forehead lines at week 4 (&plusmn;2); 100% improved &ge;1 point. MAS scores for resting and dynamic lines, and eyebrow positioning were significantly improved (P<0.001). Eyebrow po
