The Teosyal RHA line has some new formulations of dermal fillers created for specific areas of the face. RHA fillers are also composed of HA (HA), a substance found in our bodies and tissues. It is safely absorbed by our skin when injected and naturally breaks down after a while. It promotes a youthful appearance by filling in volume and reducing the wrinkle appearance. 


RHA dermal fillers have many advantages over traditional HA fillers because of the Resilient HA (RHA) composition. The molecules of RHA are more flexible and better settle underneath the skin. This is best suited for facial concerns with constant movement. In addition, the product’s elasticity avoids a lumpy look when introduced to the skin. There are four different RHA products: RHA 1, RHA 2, RHA 3, and RHA 4. Each has cross-linked HA molecules and is designed for specific concerns to produce different results.
