A thread lift is a procedure that gives a subtle lift to the skin. The difference between a thread lift and a facelift surgery is that a facelift surgery removes the sagging or loose skin through a surgery. A thread lift on the other hand just simply suspends certain part of the loose skin to lift it back up. Lifting the skin is an ideal process because in this way the healing response of the body is provoked. If this happens then our body naturally commands large surges of collagen to the treated areas. Collagen plays a vital role in the healing process so this plays a very important role.
