Cosmetic fillers are substances that smooth wrinkles and folds by bulking up the tissue underneath. Doctors inject them directly into problem areas. Collagen is the oldest and best-known cosmetic filler. Newer options include hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, polymethylmethacrylate beads (PMMA), and ordinary fat that comes from your own thigh or belly.
Generally, you can go back to working out two to three weeks after breast lift or breast reduction surgery. This depends on how you feel. Do not lift anything that weighs more than five pounds for three weeks. Avoid contact sports for six weeks. If you had breast enlargement with a breast lift, hereafter avoid all exercises which isolate your pectoralis muscles as these can shift the implant toward you armpit. Workouts must stop if you experience discomfort in your breasts or chest. A balance of rest and reduced activity will speed up your recovery.
