Ammi PDO Cog Threads  23g x 38 mm 20 pieces These cog threads are inserted with a sharp needle If you really want some lift, cogs are the way to do it! These little barbed biodegradable threads are placed under the skin and lead to tightening and lifting. The barbed threads are placed under the skin with a cannula or with a fine needle that is attached to the absorbent thread. The needle is inserted into the subcutaneous layer and when removed, the cog threads remain implanted. Cogs provide an easy way to lift multiple areas, such as sagging cheeks, jawlines, brows, arms, thighs, abdomen, and of course, the oh-so-dreaded jowls. They can improve pores, reduce fine lines and wrinkles by encouraging collagen fiber synthesis.  Polydioxanone (PDO) threads are a special medical grade thread that is thinner than hair and made of protein. Research has shown that a foreign body in the skin causes a reaction that improves the blood flow to the area and stimulates neocollagenesis (the production of new collagen in the skin). It also stimulates elastin and hyaluronic acid, both substances are key to maintaining firm, youthful looking skin. The cog threads are dissolvable and will  be reabsorbed in 6 months.  They leave behind all the good stuff like collagen and  elastin, and you continue to see results for another 2-3 years! You can expect to see results like: Lifting Tightening Elasticity Collagen Production Improvement in skin texture Fewer lines and wrinkles An overall sense that you are defying gravity, one thread at a time. SHINE BRIGHT, BEAUTIFUL YOU!!
