28 and have had dark circles since I was 15 (which suddenly appeared after struggling with insomnia) and have never gone away. There is hollowness but it’s the discoloration (bordering more red-pink than purple) which bothers me most. I had three sessions of PRP/PRF last year but it didn’t do much. I’ve been hearing a lot about polynucleotides and am wondering if it’s worth trying, or even with the risks of under eye filler, if that is a better option in my case?
