An aged face results from not only the skin but also subcutaneous fat layer and special layer called SMAS (Superficial Musculoaponeurotic System), which are located between the skin and muscle layer. Therefore, a simple facelift that tightens only the skin flap wouldn’t have a long-lasting effect but would leave a large scar on the cutting line. This is because the incision is sutured without other layers of the entire skin tissue.
MACS-Lift (Minimal Access Cranial Suspension) was a recently introduced facelift method, a procedure of peeling the skin and tightening the SMAS layer with a thick, medical thread. This surgical method may cause unnatural facial expressions, and may not be effective in improving the sagging of the frontal face and jawline; the result is not long lasting (lasts only several months) without peeling the SMAS layer.
