‌Injectable substances and functional ingredients‌: The main ingredient of water light needle is hyaluronic acid, and its quality standards need to be clearly defined, including parameters such as concentration and purity. In addition, depending on the product design, other ingredients with specific cosmetic functions, such as antioxidants, vitamins, etc., may need to be added.
‌Injection system design‌: The microneedles of water light needles need to be designed to be small enough to ensure comfort during injection and reduce patient discomfort. Some products may use automatic injection systems, and a stable, reliable, and easy-to-operate injection mechanism needs to be designed.
‌Dose control‌: Accurate control of the injection dose is key to ensure that each injection provides consistent results.
‌Injection device materials‌: Injection devices need to use medical-grade biocompatible materials to reduce the risk of allergies or other adverse reactions. The device should be durable enough to ensure that it does not fail under normal use conditions.
‌Safety Design‌: The design of the injection device should have a mechanism to prevent reuse or abuse to ensure the safety of the product. In addition, the water light needle product needs to be highly sterile to prevent the risk of infection.
