Do dermal fillers have any long term anti-aging benefits like preventing additional volume loss or boosting collagen production?

Repeated dermal filler injections can actually stimulate your body's own collagen production, which will potentially allow you to use less filler on each subsequent treatment.

Thanks for your question. Voorhees at the University of Michigan was the first to show that HA fillers would squeeze collagen producing cells and cause them to create more collagen. In my own practice I have definitely noted that patients who get filler treatments regularly not only need less filler upon re-injection, but the effect seems to last longer, too. I hope you find the same to be true for you!

Yes, HA fillers get replaced replaced by your body with collagen. HA is the natural scaffolding for growth and organization of new collagen. But collage ages and stretches and breaks over time, with sun, smoking and hormonal fluctuations and need stimulation and replacement to maintain volume and elasticity of soft tissue.
