First, I want to acknowledge how hard this has been for you. Long-standing under-eye darkness and hollowing can be incredibly frustrating—especially when it’s something you’ve noticed since childhood and have worked so hard to hide. Your feelings around this are completely valid. That said, there are important reasons why most experienced injectors set strict age limits for tear-trough (under-eye) filler, and it’s not about dismissing your concern. Why under-eye filler is usually avoided at your age Under-eye filler is one of the highest-risk cosmetic injections on the face. In younger patients especially: Facial bones and fat pads are still changing and maturing Early filler can shift over time and look worse as your face evolves The tear trough area has delicate blood vessels—serious complications, though rare, are real What looks like “volume loss” at 18 is often genetic anatomy or pigmentation, not true aging-related hollowing For these reasons, ethical providers will not perform this procedure on someone under 21—and trying to “find a way around” that limit is not in your best long-term interest. What you’re likely seeing instead From your description, this sounds like a combination of: Genetic tear trough anatomy Thin under-eye skin Pigment showing through (not actual darkness) Possibly mild allergic congestion contributing to shadowing These issues do not always improve with filler, even in adults—and in younger patients, filler can sometimes make things look heavier or more uneven. What you can do now (and what actually helps) There are meaningful, safer options at your age: Medical-grade eye creams with ingredients like caffeine, niacinamide, vitamin C, or retinoids (used cautiously) Consistent sun protection, which makes a bigger difference under the eyes than most people realize Addressing allergies or congestion, which can deepen under-eye shadowing Color-correcting concealers (peach/salmon tones) rather than heavier coverage In select cases, non-ablative laser or light treatments for pigmentation or skin thickness—these are sometimes appropriate even for younger patients when done conservatively These approaches won’t “change your face,” but they can significantly soften what you’re seeing and prevent it from worsening. Looking ahead If, after facial maturation, under-eye hollowing remains a concern: Tear trough filler can be considered later, when anatomy is stable At that point, small amounts placed deeply and conservatively can be very effective Waiting often leads to better, more natural results—not missed opportunities The most important takeaway I know how tempting it is to want a fast fix—especially when something has bothered you for so long. But under-eye filler is not a benign procedure, and doing it too early can create problems that are far harder to fix later. Protecting your face now is the best investment you can make in how it will look in the future. Your concern is real—but patience here truly works in your favor.
