Dr. Hosung Choi of Piena Clinic has released a hands-on video showcasing his injection techniques using HiloWave. In this session, the editor of the publication personally volunteered as a patient to evaluate the treatment’s effectiveness and pain level firsthand.
HiloWave is formulated with both high- and low-molecular-weight hyaluronic acid (HA), cross-linked with a minimal amount of BDDE. Its excellent spreadability, natural volume enhancement, and long-lasting results have made it a standout in the medical aesthetic market. Dr. Choi highlights HiloWave’s particular strength in midface rejuvenation, effectively addressing nasolabial folds, volume loss, and age-related skin sagging.
The first part of the video focuses on the preliminary steps, including anesthesia, cannulation design, and injection planning. Dr. Choi offers detailed insights into choosing between cannulas and needles, determining injection depth and angle, and setting entry points —practical knowledge that can immediately benefit fellow practitioners. Given the editor’s sensitivity to pain, Dr. Choi employed his signature VIP anesthesia method. Though more time-consuming, this technique greatly reduces discomfort and is ideal for sensitive or high-profile patients. Even the editor, who typically avoids needle procedures, was able to receive both cannula and injection treatments comfortably. This method provides valuable insights for physicians treating patients with pain sensitivity.
The hands-on video further demonstrates real-world considerations such as cannula size selection, injection pressure, and control of injection volume and speed. Dr. Choi also shows how to visually and manually assess treated areas for uniformity, gently compressing any raised points to prevent long-lasting bumps or unevenness. By layering HiloWave using both cannula (subdermal) and needle (intradermal) techniques, a method Dr. Choi refers to as a “sandwich approach,” he achieves both a lifting effect and improved skin texture. The low-molecular-weight HA plays a key role in quickly improving skin tone and surface quality, while the high-molecular-weight component enhances structure and support.
With over 20 years of experience in injectables, Dr. Choi emphasizes the importance of using techniques that are not only effective but also safe and intuitive. His preference for methods that minimize risk while optimizing outcomes is evident throughout the procedure. The full technique, from treatment design to clinical tips and post-injection checks, is available to view in the full-length video below.
