Hey, T.

Old farts w/ baggy skin and angular features on the neck have this issue. Alot. Here's where the experimentation w/ stretches and strokes comes into play (like Ryan said). I still try new S&S for some areas. I've also tried stroking the concave areas the same way as the Coup de Maitre on the mustache, where the blade almost rotates on the axis of the spine. It'll take some experimentation and some time to find the right combination. The smiling blade is great for those concave areas. Less so for the wide, flat cheek. It definitely took me longer than 2 months to learn. I hope I learn some day
