Context: I’m a 25 year old. I have extremely deep creases on my lips (in spite of being hydrated, and using humectants & locking them in with occlusives on my lips). The deepest creases I have are along my bottom lip. The ONLY thing I want to change about my lips is smoothing these creases (not changing the shape, color, or size of my lips). I do not want to use any kind of filler. Is there any documented or case of treating lip creases without filler by a physician?
