Breast lift with implants, and future explant - how should I proceed? (Photos)

Hi I am considering options I am 54 and currently have 490 and one 415 cc implants, had a rupture in 2016 and had implant revision and exchange of implants. I had multiple revision surgeries due to double bubble, last revision in 2016. I had a disastrous infection and had allergic reactions to antibiotics Was in hospital for a few weeks, only to inevitably have the implant removed and I had to have it out for a year, after 2 years I had revision and downsized a bit, had pretty bad scarring inside and was pretty deformed breast for the outside, I probably should have had a lift too but anyway suffice to say I wasn’t happy with the result there are Pretty saggy and uneven. I have a misshaped pectoral muscle on one side as one of the muscles was cut too far on original surgery and there is a noticeable deformation When I flex, anyway I’m considering a lift and replace implants at 400cc, howeve I’m also considering do I just do a lift and explant, but I’m not sure I’m ready for that . I do have some health issues itchy rash on torso and bad asthma I’ve wondered if I have an allergy to the silicone, do I get the implants out and lift and then in six months see how I am and how I feel then get implants if no change in health, is this possible to have implants after explant abd lift ? or do I just get implants and lift and then in 10 years get explant at 65, would I need another another lift then I don’t want implants at 65, thanks
