Dear Ana M G: Any time the tissues undergo an injury, like a cut (small injury or face and neck lift (larger injury), a cascade of events occurs heal the body. The “scar” you see along the incision line follows the same healing progress as the tissues that were lifted under the skin. The same cells, proteins, blood vessels, nerves, and scaffolding are used in the repair of as they do under the skin. Scars become more stiff, thickened and irregular, ie. lumpy, swollen, bumpy than natural uninjured skin. Much of this is because it is collagen developing in a random alignment that is laid down rather than the basket weave pattern and stretchiness of natural dermis. This allows for strength but not elasticity. Collagen is the thread that holds the a wound or incision together. It is not produced by the fibroblast for some 10-14 days after the cut was made. So, it is sutures and fibrin which glue, approximate and make waterproof the cut. As with the “ying and yang” balance of all body functions, so is it with collagen or scar formation. Changes over time occur. Production and break-down of collagen over 1-2 years yields the strongest, most flexible and thinnest final scar. Most of the time, scar production peaks in thickness, lumpiness, swelling, redness and irregularity in 12 weeks (3 months) and has subsided by 6 months. Another 6 months or more of scar remodeling occurs to breakdown the thick, lumpy scar into a smooth, thin sheet or line scar we desire. With this background it is understandable how each patient’s repair process is unique and will differ in quality. While surgeons desire a perfect scar and smoothness every time, scars are permanent reminders of the injury to the skin of a quality predestined and not overly influenced by surgical technique. Consider massaging techniques to assist in remodeling your skin. If you have any further questions, contact your surgeon. Always consult with a well-qualified Board Certified Plastic Surgeon regarding your concerns. I wish you all the best!
