But Lamees Hamdan, founder of Dubai-based luxury natural skincare brand Shiffa, admitted that cheap “jade” rollers are not likely to be made of the precious stone, but rather plastics.

Karina Sulzer, founder of Los Angeles-based Skin Gym, says the roller’s success is due to its simple usage. “As a millennial, our generation will do research before we buy anything. We want something simple and traditional."

She is also trying to make the traditional tool innovative, as her product is based on crystals with different functions, including one that adds moisture, and another for fighting acne. Her hope is that customers can make personal purchases according to their skin conditions.
