We’re often told that dark circles under the eyes are simply genetic — a trait passed down like eye colour or bone structure. But at Mesglo Aesthetic Clinic London, we know that the story is more complex. In fact, the vast majority of patients we see with persistent under-eye darkness aren’t suffering from pigment issues alone — they’re showing signs of structural ageing, lifestyle impact, or skin degeneration that can be corrected.

In this deep-dive article, we explore three of the most common but underserved aesthetic causes of dark circles, what makes them different from hereditary hyperpigmentation, and how to treat them with modern, non-surgical, regenerative solutions.

Cause 1: Midface Volume Loss and Shadowing

What’s really happening?

As early as your late 20s, your midface fat pads begin to shrink and descend, leaving the under-eye area unsupported. This creates a shadow in the tear trough (the groove between your lower eyelid and cheek), making the area look darker — even if there’s no pigmentation.

It’s not about colour. It’s about anatomical light loss. You can brighten the area with every eye cream on the market, but unless you address the midface structure, the hollowness — and its shadow — will remain.

How we treat it at Mesglo

We take a layered approach using non-volumising, precision-targeted injectables. Instead of “filling the trough,” which can lead to puffiness, we support the structure from the cheeks upward:

- Cheek Enhancement restores midface volume to reduce downward shadowing.

- Polynucleotides for Face strengthen skin and boost fibroblast activity without heaviness.

- For select cases, we use micro amounts of filler in a blended tear-trough-cheek technique, which provides lift rather than weight.

This restores smoothness and light reflection under the eyes — correcting the “dark” effect at its structural root. https://mesglolondon.co.uk/?p=3962
