Novathreads are hypodermic needles preloaded with a synthetic PDO absorbable suture. PDO (polydioxanone) sutures are surgical sutures that are used to perform cardiac surgery. All sutures are FDA-approved and PDO sutures are one of the safest materials that can be used in the body. Your skin will fully absorb the Novathread within 4 to 6 months without leaving any scar tissue. While the sutures are underneath the skin, however, your skin gently reacts to the skin creating a “selective inflammatory response” to produce collagen to create a longer-lasting result: This principle is behind a lot of aesthetic procedures (such as fractioned lasers, skin tightening treatments and microneedling). Our skin is excellent at repairing itself, and by inserting the Novathreads underneath the skin to lift the loose skin, the skin will heal itself by creating new collagen naturally!
