Like other dermal fillers, Teosyal RHA 4 works by adding hyaluronic acid subcutaneously. The hyaluronic acid helps to hydrate and support the skin, restoring volume. Teosyal RHA 4 contains a mixture of cross-linked hyaluronic acid, which lasts longer within the skin before breaking down, and non-modified hyaluronic acid, which acts more like natural hyaluronic acid within the skin, stretching and moving with ease. These substances gradually break down within your patient’s skin, absorbing into the body.
Teosyal RHA 4 usually lasts about 6 to 9 months within the skin, so your patients should expect to return to your clinic once or twice a year for touch-ups.
