I would like to inquire about the effects and price of lip fillers.

I'm worried because my lips are usually too thin and look lifeless.

Whenever I do lip makeup, I tend to draw a large line to create an over-lip look, but it is cumbersome and the staying power is poor, so I am looking for a fundamental solution.
Seeing how many of my acquaintances use fillers to create a beautiful mouth shape, I am seriously considering getting lip fillers myself.
Since this is my first time getting a filler procedure, I have many questions, so I am writing this post to ask.
First of all, I would like to know the specific extent of the filler's effects.
Whether it simply adds volume to the lips, or whether it naturally lifts drooping corners of the mouth or corrects asymmetrical lip lines
I wonder if it is actually helpful.
I am also curious if it is possible to resume daily activities immediately after the procedure, and roughly how long the effects usually last.
I'm also curious about the price range.
I heard that there is quite a significant cost difference between domestic and imported products.
I would like to know what the average cost is usually based on 1cc.
I want to find a safe hospital that does a good job with molding rather than just the cheapest place,
It would be very helpful for me to create a budget if you could provide some guidance on what a reasonable price range is.
I am carefully researching options because I want to create natural-looking yet voluminous lips.
First of all, I am really curious about the satisfaction level of those who have already received the procedure!!
