Cog thread treatment is a minimally invasive cosmetic procedure designed to lift and tighten sagging skin using dissolvable threads made of materials like PDO (polydioxanone). These threads are inserted beneath the skin using fine needles, where they create a supportive scaffold that gently lifts tissues while also stimulating the body’s natural collagen production. Over time, the threads dissolve, but the collagen they trigger helps maintain firmer, smoother skin. The treatment is commonly used on areas such as the face, jawline, neck, and brows, offering subtle, natural-looking results with minimal downtime compared to surgical facelifts
