Fillers under the eye have become very popular. The most commonly used filler for under the eyes is hyaluronic acid. Poly-l-lactic acid is another option, a synthetic material made from phosphate and calcium that energizes collagen production. Calcium hydroxylapatite, made from calcium and phosphate, is a biocompatible dermal filler that stimulates collagen production. It also supports and sustains connective tissues in the face, which can add volume overall.
I have tried many types of fillers under my eyes. Most of the time it was successful, but the last time I had fillers under my eyes, it looked terrible. On one side it looked OK, but on the other side, I had a huge lump under my eye. I went to a plastic surgeon and he had the nurse practitioner dissolve the filler. I consulted an additional plastic surgeon and he told me that he is not a fan of fillers under the eye. He uses botox lower than right under the eyes and it makes the skin under the eyes look better even though it is not filled right under the eyes.
Everyone reacts differently to fillers. For some, it is a miracle and for others, it can be problematic. It is hard to know unless you have it done. It is temporary so it doesn’t last forever. Under-eye fillers usually last about six months although some people can see results for up to a year or more.
