I had 1ml of teosyal, 0.5 under each eye to improve my tear trough hollows. The initial results were great but as the needle sites healed the filler seems to have disappeared only 2-3 weeks after treatment. My eyes now seem the same as before the treatment and the filler doesn't appear to have migrated elsewhere. I never massaged them as per instructions. Everywhere I've read it should last at least 6 months, what's going on?!? I also had no bruising just some swelling.
