I thought I was growing old(er) reasonably well (I'm 42) and never thought about any "enhancements". Just had my passport photo taken and the Nasolabial folds are really bad, of course I could try to convnce myself that is just bad lighting but my mirror doesn't lie ;). I am now v. distracted about them so has anyone had any fillers and do you recommend them and how long do they last? Is there any other alternatives? Thanks!
