What is the difference between RE2O and Juvelook? Can they be administered together?

Juvelook is a collagen promoter that induces self-collagen production, while RE2O directly fills with human-derived allogeneic dermis, so it is good to understand that their mechanisms differ. However, when RE2O and Juvelook are administered together, immediate filling and long-term self-regeneration can be expected, so they are often used in combination.
