Any operation, which involves cutting the skin will leave a SCAR.
The desire is to either HIDE the scar, or make it so minor that it is hardly noticeable.
Therefore a surgical facelift CANNOT be scarless. It can have a minimal scar.
Changes can be made using threads implanted under the skin.
When these are ineffectual, then consider a facelift.
We perform MINIFACELIFTS.
