How to Treat Sunken Under Eyes | Match the Fix to the Cause

Not all sunken under eyes are the same problem. If yours appeared after a rough night or a sinus flare-up, the fix is different than the one that works for age-related volume loss.

First: Identify What Is Causing the Hollow Look

The appearance of sunken eyes has three main causes, and treatment only works when it targets the right one.

Temporary factors. Poor sleep, dehydration, allergies, or sinus congestion can make the under-eye area look tired and shadowed. These causes respond to lifestyle changes and simple home care rather than procedures.

Structural volume loss. As skin ages, it loses collagen and fat, which can create a hollow tear trough — the groove running from the inner corner of the eye down toward the cheek. Genetics play a role too. This type of hollowing does not respond to creams or hydration alone; it typically requires cosmetic treatment.

A true medical condition. If an eye actually appears sunken deeper into the socket — not just shadowed — you may have enophthalmos, which can signal an underlying medical issue. This warrants evaluation by a clinician, not a cosmetic approach.

If your sunken look stems from fatigue, dehydration, or allergies, these measures address the root cause directly.

• Hydrate and rest. The Mayo Clinic notes that getting enough sleep and fluids can improve a tired, hollow appearance. Aim for consistent sleep and water intake before assuming you need anything stronger.
• Apply cool compresses. A cool compress can reduce under-eye puffiness, which lessens the shadow that makes hollows look deeper. Use a clean cloth dampened with cool water for a few minutes.
• Treat allergies or sinus issues. If allergies are the culprit, antihistamines or allergy eye drops may help. A sinus infection could require antibiotics from a doctor.
• Use makeup or concealer. Cosmetics can effectively reduce the appearance of hollows and shadows. This is a cosmetic fix, not a cure, but it works for many people.

Cosmetic and Medical Treatment Options for Structural Hollows

When volume loss or aging is the cause, home care has limits. Dermatologists and plastic surgeons offer several options for under-eye shadowing and hollows, each with different trade-offs.

• Dermal fillers. Injectable hyaluronic acid filler is the most common nonsurgical treatment for tear-trough hollowing. The area is delicate, and the Mayo Clinic’s guidance emphasizes that filler here should be performed by an experienced clinician. Results are temporary, typically lasting many months.
• Laser therapy and chemical peels. These treatments address skin quality and shadowing but do not replace lost volume. They may be combined with other approaches.
• Platelet-rich plasma (PRP). PRP injections use your own blood components and are sometimes used to improve the under-eye area, though results vary.
• Blepharoplasty (eyelid surgery). When excess lower-lid skin and bags contribute to the shadowed look, the Mayo Clinic describes blepharoplasty as a surgical option to remove that tissue. Some people combine surgery with fat grafting to restore volume.

An experienced clinician can tell you which option — if any — fits your anatomy and goals. A consultation is the only way to get a reliable recommendation.

When to See a Clinician

Some under-eye problems are more than cosmetic. The Mayo Clinic advises seeing a clinician if you experience vision issues, eye irritation, headaches, or a rash along with under-eye concerns. A true sunken appearance of the eyeball itself — as opposed to a hollow in the skin below it — should always be evaluated medically, since treatment focuses on the underlying condition rather than appearance.

If you’re exploring cosmetic options, the same rule applies: seek a qualified professional. Tear-trough filler is a delicate procedure, and choosing an experienced practitioner reduces risk. If you’re considering topical products for dark circles first, know that many over-the-counter eye creams are marketed for this concern but are not regulated by the FDA for that purpose — they may refresh the skin but won’t restore lost volume.
