Fillers are used to adjust the shape of your face by adding volume. There is more than one type, and they all have different effects on skin types. The most common filler among cosmetic surgery patients today is called Juvederm (or Restylane). It works best for those who want natural-looking results with minimal discomfort.
Typically people can see results after receiving the injections. However, it depends on what product and area of injection you choose for yourself as some may experience mild swelling or bruising that lasts a few days following their procedure with no long-term effects.
