✔️ Can thin and flat lips be improved with lip fillers?

Hello~ haha

Since I was young, my lips have been very thin and the arch isn't smooth, so

I am writing to inquire as it has been on my mind for quite some time!

Since my lips are thin, my impression looks a little cold, or

It feels a bit plain, and the lines don't stand out well even when I apply lipstick.

Above all, my biggest concern is that when I smile, the upper lip curls in and is almost invisible..!

My upper lip is thin, and my lower lip is also on the thinner side compared to average people.

I've even developed a habit of constantly covering my mouth when I speak.

I'd like to improve the shape and volume of my lips a little with lip fillers. Would that be okay?

I'm also curious about the capacity in cc!

And since it is the lips, when speaking, smiling, eating, brushing teeth, etc.

I move around a lot; are there any specific precautions I should take after getting lip fillers?
