Under Eye Blue Veins, Skin Thinning, Loss of Fat, and Wrinkles? Only 21 Years Old. (photo)

Hello there , 
I can understand your pain. You are beautiful young lady and II am sure you are full of energy. looking tired for someone like you is not fair. I want to recommend PRP which will help you build healthy tissue, give a glow. A filler can be combined with it but PRP is the most important factor. the increased volume will  help the blood vessels look less prominent.

The larger blue veins can be treated by surgical removal or laser.  The dark color under the eyes is due to pigment in the skin itself as well as the thin transparent nature of the skin in this area.  This darkness is very difficult to treat and may persist.  Until we have a better answer to this problem I would recommend camouflage with cosmetics.  Finally, the sunken look around the eyes may respond to soft tissue fillers or fat grafts.
