Hello, I have a horizontal line above my upper lip, I have heard it referred to as a 2nd smile line also. I’ve tried a small amount of Botox but it did not work. Filler in that space seems like it would look very unnatural. How do you treat this? Wondering if botox was not used on the right muscles. It’s apparently not something my clinician has seen very often so I’m hoping there’s insight here. Thanks
