Q: Do fillers in the lips re-stimulate collagen?
What our experts say:
Yes. Fillers can re-stimulate collagen in any area that they are injected. The mechanism of collagen production is poorly understood, but emerging theories say that it has to do with pressure on the fibroblasts in the localized area, which causes the fibroblasts to produce additional collagen. We also use platelet-rich plasma injections such as Selphyl to directly stimulate collagen production by fibroblasts by reintroducing the patient's own cytokines, growth factors and platelets into the area.
