Would This Be Considered a Uneven Skin Tan or Sun Damage? (photo)

So below i have uploaded pics, focusing on what either is uneven sun tan or sun damage. I thought this to be a sun tan, but sun tans usually go away, and what you see has not gone away since i was 17/18 years old. (I am now 22). I use to do a lot of yard work at my home (during my teen years). I would be in the sun for 4-6 hrs/day and i would never use sunscreen, except when i went to the beach. It has been like this since i was 17/18 years old . Is there any laser treatment that can fix this.
