Hi There, Personally, I don't feel that your bottom lip protrudes 'too much'. As others have mentioned, there's an infinite number of lip shapes and volumes, and everyone's ideal look is different. Many people are looking to fill their bottom lip but you are lucky that it's already full. I would suggest a small amount of filler in the top lip to bring it more in line with the bottom, when looking at your profile. This treatment can be done in a way that doesn't make a dramatic change to your top lip shape, but just alters the appearance from the side view. As injectable lip filler is not permanent, you can see how you feel with your upper lip enhanced, and go from there. I wish you luck in finding a look that you like!
