I want to get rid of my cupid's bow without lip fillers, is it possible? (Photo)

Hi. interesting question.
I recommend that you evaluate your lips to assess your lips well. On the other hand it may not disappear in its entirety but we can give it to filler aspect and disguise a little, but it is something that in the long run you will probably need the same treatment again.

That can be done. The horizontal stiff skin between the two peaks can be excised and the vermilion raised to eliminate the dip between them. Just like making a more pronounced Cupid's bow by vermilion excision between the peaks the reverse can be done to reduce/eliminate it through skin excision.
