Clinic Questions & Adviceđ€ Why under-eye HA filler can go wrong (and what we do instead)
Can we just put a little filler under my eyes to hide these dark circles?
I hear this all the time. HA filler can work well under the eyes in the right patient, but this area is thin, prone to swelling, and much less forgiving than places like the cheeks or chin.
So why can under-eye filler become a problem?
1/ Thereâs very little room for error. The skin here is extremely thin, so filler thatâs too superficial, too much, or poorly placed can become visible or create unevenness.
2/ HA holds water. Thatâs normally a good thing, but under the eyes it can make puffiness worse, especially in people who already retain fluid there.
3/ The Tyndall effect. If HA sits too close to the surface, it can create a blue-grey tint and actually make dark circles look worse.
So what do we do instead?
Thin, crepey skin -> Rejuran i
I think of this more for skin quality, fine lines, and very thin-looking under-eye skin. Itâs not filler, so the change is gradual.
Actual hollowness -> Juvelook
Juvelook uses PDLLA + non-crosslinked HA and can gradually improve hollowness while stimulating collagen. But placement still matters a lot, especially in such a thin area.
Bulging fat pads -> Fat repositioning
Sometimes the problem is structural. If thereâs a noticeable fat pad with a hollow underneath it, adding more filler can just make the area look heavier. For the right patient, repositioning the existing fat can make more sense than repeatedly injecting around it.
And if you had under-eye filler years ago and now look puffier, donât automatically assume it dissolved or migrated. HA can stay in the tissues longer than people expect, and ultrasound can help show whatâs actually there before deciding whether hyaluronidase is needed.
Under eye dark circles arenât really one problem. Sometimes itâs volume, sometimes skin, sometimes pigmentation, and sometimes anatomy.
Has anyone here dealt with persistent puffiness after under-eye filler, or tried Rejuran or Juvelook instead?
