Lip line on the pink part of the lip from a dry mouth cut. (Looking for a more permanent solution than fillers and Botox).

The cut that I attained on my bottom lip ended up bleeding a good amount, and left a medium to deep lip line. I would also like to disclose that I’m currently 19 years old, and that I’m on isotretinoin, but my treatment will be done within 1 month. I’m wondering if it’s possible to get laser or chemical peel in the pink lip area, and wether or not that would be beneficial for the lip line. If I cannot have laser or chemical peel done on my lip, what are my other options.
