Few things make us look more exhausted than dark circles under the eyes, yet a few extra hours of sleep typically don’t make much difference. That’s because dark circles aren’t just a symptom of fatigue. Instead, they stem from multiple factors, amongst them genetics, skin thickness, bone structure, pigmentation, and lifestyle, all of which contribute to how shadowed or discolored the under-eye area appears.

While drugstore creams promise quick fixes, real results start with understanding why dark circles form in the first place and addressing the specific cause rather than the symptom.

Volume-Related Shadowing

As we age, the fat pads that once supported the lower eyelid can descend or shrink. That creates a small trough between the lower lid and the upper cheek, often called the “tear trough”. Light hits that hollow, making it look darker than the surrounding skin.

In some cases, we see clients with naturally deep-set eyes or protruding orbital rims who experience dark circles, regardless of age, due to their bone structure.

Skin Transparency

The eyelid skin is naturally thin — often less than half a millimeter thick — and becomes even thinner over time as collagen and elastin degrade. As that support layer weakens, the tissue becomes slightly translucent. The darker structures beneath, which includes tiny veins and the orbicularis muscle, start to show through, giving the area a gray or bluish hue.

We’ll typically start with procedures or treatments that stimulate new collagen production to help rebuild the dermal layer because stronger, denser skin reflects light better. 

Revision C+ Brightening Eye Complex contains a stabilized form of vitamin C that supports new collagen formation while defending against the oxidative stress that accelerates thinning. Over time, firmer skin reflects light better and shows less blue-gray tone.

For patients who also need extra hydration, EltaMD Renew Eye Gel uses peptides and hyaluronic acid to restore moisture balance and encourage fibroblasts—the cells that build collagen—to stay active.

Pigment and Color Change

In some people, dark circles form because the skin under the eyes contains more melanin—the pigment that gives skin its color—than the surrounding tissue. We usually see this excess undereye melanin in patients with medium to deep skin tones, as well as those with a history of chronic sun exposure, eczema, or seasonal allergies. When the skin becomes irritated, it signals melanocytes to protect the skin with additional melanin.

To target pigment-based dark circles, we recommend products that do two things at once: 1) protect the skin from the oxidative stress that keeps telling melanocytes to make more pigment, and 2) deliver an active form of vitamin C that can actually interfere with melanin formation and support collagen.

One example is Revision Skincare Teamine® Eye Complex, which features:

  • THD Ascorbate (Vitamin C): A highly stable, fat-soluble form of vitamin C that penetrates easily through the skin’s lipid barrier. It inhibits the enzyme tyrosinase and supports new collagen formation for smoother, more even-toned skin.
  • Grape Seed & Green Tea Extracts: Potent antioxidants that neutralize free radicals and reduce inflammation, two of the main catalysts behind the production of pigment cells.
  • Palmitoyl Pentapeptide-4: A collagen-stimulating peptide that strengthens the dermal structure, improving how light reflects from the under-eye area.
  • Sodium Hyaluronate: A lightweight humectant that hydrates and subtly plumps thin skin, reducing the contrast that causes the appearance of discoloration. 
  • Mica, Silica & Titanium Dioxide: Optical diffusers that instantly soften the appearance of dark pigment while longer-term ingredients work beneath the surface.

Vascular and Circulatory Factors

At first glance, vascular dark circles can look nearly identical to those caused by thin, translucent skin. Both show a blue or purplish hue, but the underlying biology is very different.

In cases of skin transparency, the darkness is optical. You’re seeing through typical structures in tissue that has thinned due to collagen loss.

In vascular dark circles, the color comes from the vessels themselves as the capillaries under the eye have dilated and become more visible through the surface. The blood within them carries less oxygen, so it absorbs more light and reflects a deeper tone.

Topical therapy with products like NeoStrata® Intensive Eye Therapy strengthens the thin dermal layer through its MicroDiPeptide229 complex and NeoGlucosamine® technology, both of which stimulate fibroblast activity to rebuild collagen and hyaluronic acid. Thicker, denser skin helps mask underlying vessels, while added caffeine and antioxidants promote better microcirculation and reduce mild puffiness. 

The under-eye area is deceptively complex, and you need a skincare expert on your side to address the root cause of your dark circles. Advanced Dermatology & Cosmetic Institute and Advanced Skin Therapeutics can create custom-tailored solutions designed to target underlying causes of puffiness and pigmentation, refreshing and rejuvenating your look.
