Dear 1n04oC82nie, References of a suture place under the skin for revitalization, began with the Egyptians and Russian gold threads to stimulate mild skin reaction and smoothening. Today, we attribute these historical advances as injectable threads. The “new” innovation of adding cones or barbs allow for an “instant” mechanical advancement / lift / compression followed by a secondary longer term collagen tightening. As minimally invasive rejuvenation procedures advance, we must remember that the science of healing remains the same and unseen. Healing occurs as a sequential activity from injury to platelet coagulation to inflammation and scar production and finally remodeling into the final result. It takes 2-3 weeks for swelling and bruising (no matter how minimal) to significantly reduce and the first collagen molecules to begin appearing. During this time, the injected sutures (coned Silhouettes (SIL), barbed EuroThreads (ET) and others can move or loosen their grip on the surrounding fibrous entrapment of the subcutaneous tissues. My recommended post-procedural recommendations are based on this premise. Thereafter, the fibroblast stimulated collagen induction by the PDO, PLLA, PGLA made threads continue and prolong the process to firm, contract and generate more structural and rejuvenative molecules like collagen, elastin, fibronectin and many other restorative by-products. My recommendations following Injectable Threads (please follow the instructions of your chosen surgeon!) Intradermal injectable threads require a minimum of 3 days until the hair-sized strand cannot travel back out the injection site. Subdermal suspension SIL and ET sutures require the splinting of facial motion to reduce skin movement, layered shearing, buckling and loss of suspension suture lift / advancement for a minimum of 3 weeks. Reduction in swelling to reduce the amount of suture movement, popping of the anchors and therefore loss in tension of the tethering cones and barbs with head elevation, reduction in movement, diminished activities for 3 weeks. Gentle massage and iced compresses to assist in reduced swelling. Gentle compression initially with the use of a compression facial garment. Subsequent lymphatic or deeper massage for scar remodeling. Despite the simple appearance and relatively “risk-free” use of these Injectable Sutures, this option in facial enhancement is an Advanced Technique. The greatest side-effect of the procedure is disappointment and false expectations. Threads cannot provide a facelift result but they are a useful option pre- and post- facelift. If placed too close to the skin, they can cause puckering. Please, consult with a skilled, knowledgeable and experienced Board Certified Plastic Surgeon matching you as an appropriate candidate for this procedure. I hope I have been helpful. All the best!
