I am scheduled for January 3rd, however, still battling the decision of what size to get. I would like to go with the 5mm to make the procedure worth it, since my fear is that the 4 mm is playing it too safe and may be too subtle. Although I want to make my mouth bigger, I don't want them to look unnatural or like sausages. I don't have super thin lips, however I have a very narrow mouth that isn't wide, so I'm wondering how the implants would look with the shape of my lips. any feedback is greatly appreciated! Will update!
