Randomized Controlled Trial Comparative Study
Randomized, Evaluator-Blinded Study Comparing Safety and Effect of Two Hyaluronic Acid Gels for Lips Enhancement.
Hyaluronic acid (HA) fillers may differ in terms of gel characteristics and ease of use and it is of interest whether this might affect safety and duration of effect. ⋯ Both products achieved durable improvement in lip fullness and aesthetic appearance. A significantly smaller amount of HA-RK was required compared with HA-JV to achieve optimal treatment effect.

Randomized Controlled Trial
Finer Needles Reduce Pain Associated With Injection of Local Anesthetic Using a Minimal Insertion Injection Technique.
The injection of local anesthetic into the skin is often the only memorable event described by the patient after dermatologic procedures. ⋯ This study further validates the use of this technique for the injection of lidocaine and the preference of a 33 gauge over a 30-gauge needle for the initial injection on the face and scalp.
