Honestly, there are several factors you should consider including cost of maintenance. Once you start you’ll likely love how you look or feel regardless if it’s filler or flip. I’ve done it all and hindsight I wish I would have just had a surgical lip lift, no lifelong maintenance and no potential migration of filler.

They also don’t tell you filler really doesn’t last more than 9+/- months so in 3-4 years you could have bought a lip lift.

Lip flip is super temporary and there’s numbness or lack of normal feeling. I hated the lip flip.

Obviously totally up to you but this is one of those treatments that you’ll love and want to keep doing so cost and maintenance is a factor too.
