Just wondering if you have had any previous cosmetic lifts. Contour threads are for people who only have lifting and sagging to deal with not excess skin. if you have did, have you stopped smoking, is your diet good, do you keep out of the sun.
At 63, skin is aged generally and there is only so much a Surgeon should or could do. Maybe consider restaylne to the dimples/wrinkles and realistically, you probably need excess skin excised.
My belief is that you put the cart before the horse: facelift first - get rid of excess skin and then when it starts to sag, contour threads.
Hope it works out for you.
