Under eye filler at 21? Too young?

I often recommend my younger patients to start early with preventative and cosmetic treatments. For under eye, a combination approach will give the most improvement. Fillers, lasers, and microneedling/PRP can improve under the eyes. My patients try to get non surgical treatments to avoid surgery. We use PRP and stem cells there often. I suggest consulting with an expert to develop a treatment plan best suited for your short and long term goals. Best, Dr. Emer

Hi, 
So here is the scoop on putting hyaluronic acid in the eye area. Sometimes it works out great and sometimes it works out terribly. The problem is that the anatomy in that area is not always the best to receive filler and that is when the outcome can be worse than the problem itself. Yes, it can be removed, but with removal comes its own consequences to the skin in that area. So really you need to weigh the benefit with the potential risk. To me, your troughs do not look that bad. WIll they get worse over time? Maybe. But I think you could always make the decision to try filling them as doing it sooner rather than later has no real benefit in terms of prevention. 
I would also suggest that you look into carboxytherapy, as it looks like you have some discoloration under the eyes and that may be contributing to an illusion that the tear troughs are deeper than they are. CO2 under the eyes is very safe and low risk. It works to increase the circulation under the eyes an reducing puffiness and darkness caused by stagnant blood flow. It is also something that is preventative for future aging under the eyes. 
Best of luck
