Dark Circles Under Eyes — Causes and Effective Treatments

Last updated: 5 March 2026

Dark under-eye circles are one of the most common aesthetic concerns we see at Axiom Aesthetics. They can make you look tired, older, and unwell — regardless of how rested you actually feel. Understanding the cause is key to effective treatment.

Common Causes

Volume Loss (Tear Troughs)

As we age, we lose fat and bone density in the mid-face, creating hollow shadows beneath the eyes. This is the most common cause in patients over 30 and responds excellently to treatment.

Hyperpigmentation

Excess melanin production creates brown discolouration, particularly common in darker skin tones. Often genetic but worsened by sun exposure and inflammation.

Visible Blood Vessels

The under-eye skin is incredibly thin (0.5mm). Dilated blood vessels showing through this delicate skin create a blue-purple hue.

Allergies and Lifestyle

Allergic rhinitis, poor sleep, dehydration, excessive screen time, and smoking all contribute to under-eye darkness.

Professional Treatment Options

• Tear trough filler: HA filler injected to restore volume and reduce shadowing (our most popular option)
• PRP under-eye treatment: Growth factors stimulate collagen and improve skin quality
• Chemical peels: Lightening peels for pigmentation-related darkness
• Laser therapy: Targets pigmentation and stimulates collagen in the delicate under-eye area
• Skincare: Medical-grade vitamin C, retinol, and caffeine-based eye creams

The Importance of Expertise

The under-eye area is one of the most delicate regions to treat. Our Harley Street practitioners have extensive experience with tear trough treatments and understand the complex anatomy involved.
