Medicube is a Korean derma-cosmetic + beauty-tech brand created by APR Corp, led by founder Kim Byung-hoon (also behind Aprilskin). 
It is known for its targeted skin care for problems like acne, pores, and barrier care, and it often focuses on "real results" and testing that is focused on the skin. 
The AGE-R line of at-home devices, like the AGE-R Booster-H, made the brand very well-known. These devices were made to make skin glow and help products absorb better. 
Medicube now sells full routines (cleansers, toners/pads, serums, and creams) and devices. The company has grown quickly through global retail and social commerce.
