WEIFULI is a new, non-invasive, multifunctional needle-free mesotherapy system that truly replaces needle injection.
Based on technologies adapted from the aviation industry, it blasts the liquid medicine into a stream of 5-20μm microdroplets (molecular level), which is accelerated to 220 m/s (subsonic speed) and acts on the skin with a jet pressure of 7bar. As the airflow stretches the skin, the micropores gradually expand, thereby opening the natural passage of the skin, and the medicinal liquid flowing from the microdroplets smoothly enters the dermis layer, giving full play to the efficacy of the medicine.

Air flow boosts liquid velocity up to 220 m/s (subsonic speed)
Dedicated nozzle with 5-20μm droplet flow (molecular level)
Spray to expand the skin to form a pressure jet phenomenon (hydration)
Realize the dual effects of fluid exfoliation and expansion injection

Diagram1: Penetration depth comparison, needle free injection can reach to the dermis layer.

Diagram2: Hyaluronic acid is injected into the subcutaneous section at an angle of 45-90° at a distance of 0.5~1cm from the skin for 10s, 30s, and 1min. The nutrient solution between cells has increased significantly, and hyaluronic acid has entered the dermis in large quantities.

Diagram3: 2000μm subcutaneous section, there is a large amount of hyaluronic acid between the cells.
Compared with the needle transdermal, the needle-free transdermal can also reach the effective
depth of 2mm under the skin

Diagram4: After comparing the epidermis before and after treatment with 200μm slices, the stratum corneum was basically intact.

WEIFULITM needle free mesotherapy system is widely suitable for transdermal drug delivery, deep cleaning, hydration, whitening, acne, skin inflammation etc.
