There is no problem getting various types of skin care treatments after your face lift as long as you allow enough time for healing after your surgery. I would not recommend intervention for the first 6 months after your surgery, but after that I allow my patients to have whatever facial skin therapy that they like.
There should be no problem in receiving a skin surface improvement including for the problems you describe using Isolaz (vacuum therapy along with broad-band light and cosmeceutical products. However, you might consider visiting your cosmetic/plastic surgeon who performed your facelift both for a recommendation as well as to explore what services might be available in that office. Good luck.
You should be able to do all treatments to facial skin after couple of months from facelift surgery as it should be completely healed at this point. It's a concern to avoid such treatment right after surgery due to potentially compromising blood supply to facelift skin flaps.
It is always best to contact your plastic surgeon and get his/her input in this matter.
