Sculptra is an injectable biodegradable poly-L-lactic acid that acts as a collagen stimulator to replenish lost facial volume over time. This treatment is great in restoring loss of facial structure and fullness brought on by aging. Utilizing your own collagen production, this procedure allows for long-lasting, natural results without looking "done". Sculptra works most effectively when done in a series of treatments over several months. How many sessions would need to be discussed with your aesthetics provider, however once the series is completed, maintenance is minimal.
