Are there any procedures to soften and make my cupid bow less prominent? (Photo)

you can do fillers around it to blend them more or do surgical change but I wouldnt do that. fillers would be a good option.

lip fillers and lift will not help the corners of your mouth, that needs botox, threads or a lip corner lift.  sometimes an early face/neck lift helps. accutite can be a non invasive alternative. I would use daily hydration and plumping (see emeragecosmetics.com lip essentials kit).  everyone can do a little filler when done well really gives nice hydration and plumping.  Best, Dr. Emer.

Dear lyline,
I typically use Juvederm for my lip sculpting. There are two main focuses of lip injections, adding volume and actually sculpting the shape. Both involve injecting the filler in different areas of the lips and patterns.
I would recommend finding a plastic surgeon to perform you lip injections. Most of my patients have results that last at least 6 months.

In the hands of an experienced plastic surgeon, a filler can be used to create exactly what it is you're looking for and soften the sharp angles of your cupid's bow. I hope this helps and good luck from New York City plastic surgery
