What are these dents on my cheeks called? (Photo)

Evening. I'm a 28 year old male who has noticed for the last year or so, these dents on my face. I was wondering what are these called and what procedure can be done to minimize them or get rid of them. These make me look about 7 years older and realized, by looking at pictures, that I had these for the last two years more or less and seems to be getting worse. I don't know if this helps but by body fat is around 27%, maybe more.
