A defined jawline is a cornerstone of facial attractiveness, and our PDLLA-PCL jawline treatment provides long-lasting firming and definition through collagen stimulation rather than simple volume addition. By delivering PDLLA-PCL microspheres along the mandibular border and pre-jowl area, this treatment triggers your body's natural collagen production process, gradually firming and tightening the jawline over several months. The result is a sharper, more contoured jaw with improved skin firmness and reduced early jowling. This approach provides more natural, longer-lasting results than hyaluronic acid fillers alone, with improvements continuing to develop for up to 12 weeks post-treatment and lasting up to 2 years.
