After a first filler procedure for under-eye bags, is it best to underfill than overfill, and go back to get a touch-up?

It is always best to start conservatively. Additional product can always be used to layer and achieve a satisfactory result, but dissolving too much product is more troublesome. Wait two weeks before attempting a touch up to be sure that the original product has perfectly settled and no residual swelling is present. Best of luck!

Hi & thank you for your question. It is always best to start with less and add more. Let things settle for a week , see how you like it and go back for additional filler if you desire.Hope this helps

I always do cheeks before undereyes and when doing under eyes I do with cannula to limit complications and do conservative amounts.  Best, Dr. Emer.

I definitely prefer the less is more approach when treating underneath the eyes with fillers. It is always easier to add more than to take away too much (even though hyaluronic acid fillers are dissolvable). One syringe of filler is enough to make at least some improvement underneath the eyes. Unless the filler wasn't injected in the correct place, then that's a whole different story. I would give it 2 weeks and then follow up with your injector. If more is needed then it can be given at that time. Hope this helps answer your question.

One syringe is usually enough for under eyes but not if it was injected in the cheeks.  It is good idea to undercorrect and be conservative.See an oculoplastic specialist for eyelid filler injection.
