What are the differences between domestic and imported lip fillers, and will the bruising and swelling be manageable?

Hello

My cupid's bow is indistinct and my lower lip is on the thinner side, so I'm considering getting lip fillers to make it look more vibrant.

Since this is my first time getting fillers, I'm being cautious because I'm worried it might look too obvious or the injection site might look unnatural. With so many types of fillers available—both domestic and imported—I'm asking to know which formulations are commonly used for sensitive and thin areas like the lips.

Do you tend to experience significant bruising or swelling immediately after the procedure? I am hesitant because severe bruising will be very noticeable when I go to work or have appointments. I would appreciate it if you could share your experiences regarding the actual recovery speed and how long it took for the natural shape to set.
