Hi and thanks for using the forum.
The hardness you are describing is scar tissue and it is very common when you have a laceration that has been sutured. The wound should continue to soften over time, but you can appy Vit. E to the scar to help soften up the tissue. Also, if the scar is very noticable, there are over the counter medications ( one example is Mederma) that can help fade and soften the scars and make them less visible. You may always have a mark on your lip, but these things can help make it less noticable. Finally, if you feel these are not the right answers for you, you could see a dermatologist or a plastic surgeon who may have other options for you. Good luck.
