Question : What are dermal fillers? Are they the same as injectable fillers?
Answer : The skin consists of two parts, the epidermis, which is the top layer of the skin, and the dermis, which is the bottom layer of the skin. Most fillers are injected into the dermis. You can inject into the superficial or the deep dermis depending on the type of filler. All fillers that are injected in the dermis are injectable fillers by definition.
