Best Treatment For Skin Depression On Cheek? (Photo)

I have a skin depression in the shape of an inverted Y on the apex of my cheek. This is a strictly topographical issue which is particularly accentuated by overhead and oblique lighting. Let's just say I now hate cloudy days. While I'm not sure when exactly it manifested, I noticed this about 3 years ago and used to have repeated breakouts in this area about a decade ago. I'm very much interested in what the best approach would be to resolving this.
