Without a photo it is tough but I would certasinly get on a good skin care program such as Nia 24 or Obagi,These can help reverse sun damage.Alight peel or laser may be good for the fine lines.
You're very young and, without a photo, it is impossible to determine whether you are a candidate for any procedure. One important thing you can do is to stay out of the sun or to use and reapply sunscreen religiously to reduce premature aging of the skin. You could consult a dermatologist or plastic surgeon about a laser procedure if the condition is significant enough to warrant intervention.
