First, it sounds to me like you need to have consultations with experienced, board certified plastic or ENT-facial plastic surgeons. They would give you a well- designed plan to address skin, underlying fat and muscle, looseness, laxity, etc. Your focus should be on selecting an experienced surgeon for the facial rejuvenation surgery and non-surgical care, rather than pre-selecting a method for the treatments. The entire professional service you receive is more important than individual steps of an operation. Search for quality, not features.
Second, the individual methods you mentioned in your post all address different aspects in facial rejuvenation. Re:pair is a method that generally gives mild improvements in skin texture with multiple treatments. Botox decreases excessive localized muscle activity. Browlift can reposition lax forehead tissues, improve over-active muscles, raise eyebrow position, and more. None of these methods addresses the under-eye bags that you mentioned. None address a droopy eyelid. (This might need the expertise of an ophthalmologist / oculoplastic surgeon.)
In short, start over at the beginning. Select an excellent surgeon for evaluation and on-going care.
