Dark circles are one of the most frustrating concerns because they are often caused by several different factors at the same time. The fact that you’ve already had a small amount of cheek filler and tear trough filler 3–4 years ago without improvement is actually very useful information—it suggests that volume loss is probably not the only cause of your dark circles. In my experience, under-eye darkness usually falls into three main categories: Shadowing from hollowness (tear troughs) Pigmentation (brown or gray discoloration) Visible blood vessels or thin skin creating a bluish or purple appearance Filler is most effective for the first category—shadowing caused by a hollow under-eye area. If the darkness remains even when the lighting is good and the area has been volumized, I would start thinking more about skin quality, pigmentation, or vascular show-through. Why the cheek filler may not have changed the circles A small amount of cheek filler can improve support to the lower eyelid and soften the transition between the cheek and the under-eye area, but it often does not significantly change true dark discoloration. Likewise, tear trough filler from several years ago may have either: completely dissolved over time, or left some residual filler that is no longer providing meaningful support. If the area is not obviously hollow now, adding more filler may not be the best next step. What I would consider instead 1. Determine the type of darkness A simple clue: Brown when you stretch the skin → more likely pigment Blue, purple, or shadowy → more likely vascular or structural Worse with fatigue or allergies → often has a vascular component 2. For pigmentation If the circles are brownish, treatments that may help include: Azelaic acid Vitamin C Niacinamide Retinoids (used carefully around the eyes) Occasionally chemical peels or pigment lasers in experienced hands 3. For thin skin and vascular show-through When the skin is very thin, the underlying muscle and veins become more visible. In those cases, I often think about: PRF (platelet-rich fibrin) injections Fractional laser resurfacing Radiofrequency microneedling Polynucleotide or skin-regenerating treatments (where available) These approaches aim to thicken the skin and improve its quality, which filler cannot do. 4. If there is still a mild hollow A careful assessment is important because sometimes patients who have had filler previously develop persistent edema or contour irregularity, and adding more filler can actually make the under-eye area look heavier and darker. My overall impression Since you’ve had: tear trough filler twice in the past, and recent cheek filler with little change in the dark circles, I would be cautious about simply pursuing more filler as the next treatment. In someone with persistent dark circles despite prior volumization, I would be much more interested in evaluating: skin thickness, vascular discoloration, pigmentation, and whether any residual filler is still present under the eyes. For many patients in this situation, the most noticeable improvement comes from treating the skin itself rather than adding additional volume. Procedures that stimulate collagen and improve under-eye skin quality often provide a more natural and lasting improvement when filler has already failed to address the darkness. One encouraging point is that the fact that the cheek filler did not make the area worse suggests that your concern may be treatable with a more targeted approach, rather than being an untreatable structural problem. The key is identifying whether the dominant issue is pigment, vessels, or skin thinning, because each of those responds to a very different treatment strategy.
