At Clapham Aesthetics we use only the safest hyaluronic acid-based dermal fillers which are semi-permanent only. The effects will fade gradually as the filler biodegrades but should last between 9 to 12 months. Excessive exercise or dehydration can contribute to minimizing the benefits of hyaluronic fillers. To maintain your fuller lips it is recommend that you come back to us on an annual basis or sooner for a smaller top up if desired and deemed suitable. The filler will biodegrade and be excreted naturally over time.
