What are the characteristics of a good scar removal product?

A good scar-removing product must have safe ingredients. Products that have obtained medical patents through strict medical experiments, such as Bayu hyaluronic acid silica gel, have not only obtained national patent certification, but also the experimental results of sodium hyaluronate combined with silica gel membrane on hypertrophic scars after wound healing show that its effects in scar color, thickness and hardness are better than those of silica gel membrane products alone.
