What are facial injectables and where would they help with my dull/tired looking face? (Photo)

I'm 21 and for the past year I feel like my face has looked dull and tired all the time no matter how well I keep up with my skincare. I especially feel like my under eye area constantly looks dull/dark. I struggled with acne and feel like my skin has taken a beating because of it as well. Would fillers under the eye help? What treatments would you recommend to help the dullness/tiredness?
