I am a 25-year-old male, and I would like to attain more facial definition (especially in the cheek area), similar to actor Henry Cavill's cheeks. Most of the time, my face seems to have kind of a chubby/fat look. I have included a pic of what my face looks like after I have run 6-7 miles, since I seem to have more definition due to having lost temporary water weight. Would fat injections be enough to gain more hollowing/definition in my cheeks? Or would it be necessary to get implants?
