Elravie is a monophasic dermal filler based on hyaluronic acid of non-animal origin, created using HI technology. The technology consists of the activation of HA molecules, in which the greatest number of bonds between the molecules of HA and BDDE is formed during crosslinking process. This leads to decrease in the amount of residual BDDE and formation of a stable filler structure. Therefore, risk of edema and allergic reaction after the procedure is significantly reduced.
