Neck skin laxity is a challenging concern that many patients find difficult to address without surgery. Our PDLLA-PCL neck tightening treatment offers an effective non-surgical alternative, using collagen-stimulating microspheres to rebuild the structural support within the neck skin. The treatment is delivered through precise injection points across the neck area, triggering progressive collagen and elastin production that gradually tightens, firms and improves the quality of the neck skin. Over 8–12 weeks, patients notice a visible improvement in neck firmness, reduced crepiness and a more youthful neck-to-jaw transition. Results can last up to 2 years, making this one of the most long-lasting non-surgical neck treatments available.
