Once your lips are as big as they’re going to get, you need to keep going with your lipcare routine, keeping them moisturized, and continue using the plumper once every day or two. Lip plumping requires a little bit of effort (if you can call it effort to use a plumping product and lipbalm regularly) to maintain bigger lips, but I think it’s worth it because I like how my lips look when they’re plumped.
