How long does it take for hyaluronidase to erase the effects of hyaluronic acid filler?

The corners of my mouth look turned down, like I'm frowning or unhappy, when I am not showing any expression. Can lip injections help turn the corners of my mouth up?

Which lip filler lasts the longest? Do the new lip implants feel stiff? Can you still pucker your lips with them in?

I want to have fuller lips but I don't want that 'duck bill' look of overfilled lips. What is the best way to keep my results natural?

I would like to enhance my upper lip, what is the best procedure for a permenent fix?

I am 54, recently quit smoking, and have very thin lips. I would love to reward myself with this type of procedure. Please give me the information on this to help me decide if it is for me. Thank you in advance

What are the pros and cons for each?

I had my lips done before once by a different doctor, and all went well afterwards a massage. I went to a new place and she put Restylane in but did not massage at all, and told me not to touch my lips. She then wanted to inject a small amount into the small circle on the center of the top lip under my cupid bow, and I let her. Shockingly, she injected it on the inner soft tissue of my top lip and it hurt, even though I was numb. It's been seven days and it still stings off and on and it is red.
