Dissolve lip fillers before lip lift? I've have fillers for 2 years (4.5 ml over that period). (Photos)

I noticed that my lip never is how I like. I also noticed that my nasolabial fold became deeper and the skin next to my nose started to sag. Is that because of the weight from the fillers? I decided to have a lip lift in 12 months. I will dissolve the fillers before my operation so that my lip will be in their natural state. Can I reverse the damage if I dissolve my lipfillers, and can the sagging/lines become worse the longer I wait?
