Rejuner Black is a liquid polycaprolactone (PCL) collagen stimulator made by NOHTUS Co., Ltd. in South Korea. It contains 23% particle-free PCL and is the Rejuner version positioned for thin, delicate skin such as the temples, under-eye area and neck. Each box holds five 2 mL vials.
What is Rejuner Black?
Rejuner Black is a biostimulator with 23% polycaprolactone in a particle-free colloid. Because the PCL is solubilized into a liquid, there are no beads to clump under thin skin.
Older PCL products use solid microspheres. Rejuner’s liquid form is the main reason clinics choose it for delicate areas.
What is Rejuner Black used for?
Rejuner Black improves firmness, fine lines and texture by supporting collagen production. It works by stimulation, not by filling.
- Temples
- Under-eye area
- Neck
- Fine lines in thin skin
How is Rejuner Black used?
Rejuner Black is injected into the dermis through a 33G to 34G needle, or with a mesotherapy injector. A course of about three sessions, roughly a month apart, is commonly described.
The clinician sets the volume per area, and changes are described at 4, 8 and 12 weeks. There’s no lidocaine in the vial. Follow the manufacturer’s instructions. Rejuner Black is for licensed medical professionals only.
