Can Salmon DNA Be Injected Under the Eyes? #

If the skin underneath your eyes is becoming thinner, crepey, or more lined, you may have heard about salmon DNA injections for the under-eye area.

The short answer is: yes, certain purified polynucleotide (PN) and PDRN products are used internationally as injectable treatments around and beneath the eyes. The goal is generally to improve the quality of the skin, rather than to create the volume associated with traditional under-eye filler.

Recent clinical research on periorbital polynucleotide injections has reported improvements in under-eye appearance, fine lines, hydration, elasticity, and overall skin quality. However, research is still developing, products vary, and “salmon DNA” is a broad marketing term rather than the name of one standardized injectable. (PubMed)

That distinction is important before deciding whether this treatment is right for you.

What Are Salmon DNA Injections? #

“Salmon DNA” commonly refers to purified DNA-derived compounds obtained from salmonid sources.

Two terms you may see are:

PDRN — polydeoxyribonucleotide

PN — polynucleotides

Although PDRN and PN are often grouped together in marketing, they aren’t necessarily identical. Products can differ in molecular characteristics, concentration, formulation, intended use, and method of administration.

These treatments have gained attention in regenerative aesthetics because of their potential effects on skin hydration, fibroblast activity, collagen-related remodeling, elasticity, and tissue repair. (EyeWiki)

Why Use Salmon DNA Under the Eyes? #

The under-eye area is one of the first places many people notice changes in their skin.

That’s partly because the skin around the eyes is naturally thin and delicate.

With aging, sun exposure, and changes in collagen and elasticity, you may begin noticing:

• Fine lines
• Crepey texture
• Thin-looking skin
• Dryness
• Reduced elasticity
• Rougher texture
• A generally tired appearance

Polynucleotide treatments are interesting because they focus primarily on improving the condition of the skin itself.

That makes them different from traditional tear-trough filler.

What Can Salmon DNA Do for Under-Eye Skin? #

The main goal isn’t to make the under-eye area look fuller.

Instead, polynucleotides are generally used to improve dermal quality.

A recent review comparing polynucleotides with hyaluronic acid for under-eye rejuvenation found that PN treatments showed consistent improvements in skin-quality measures including elasticity, hydration, and fine wrinkles. The authors also emphasized that more standardized, high-quality studies are still needed. (PubMed)

For the right patient, that may translate into under-eye skin that looks:

Smoother.

More hydrated.

Less crepey.

More resilient.

More refreshed.

The result is intended to be subtle rather than a dramatic change in facial structure.

Can Salmon DNA Improve Under-Eye Fine Lines? #

Potentially, yes.

Fine lines around the eyes can develop because of several factors.

There may be:

Muscle movement + collagen loss + thinning skin + dehydration + sun damage.

Polynucleotides address the skin-quality component rather than stopping facial movement.

A prospective study of 42 patients receiving intradermal polynucleotide injections for under-eye rejuvenation found significant improvements in patient-reported lower-eyelid and crow’s-feet appearance. The greatest improvements and satisfaction were observed around three months after two treatment sessions. However, this was an uncontrolled observational study, so larger controlled trials are still needed. (PubMed Central (PMC))

Can Salmon DNA Help Crepey Under-Eye Skin? #

This is one of the reasons polynucleotide treatments have become popular.

Crepey under-eye skin can be associated with:

• Reduced collagen
• Loss of elasticity
• Dehydration
• Thinning skin
• Chronic UV exposure

Because PN treatments focus on improving skin quality rather than simply adding volume underneath it, they may be appealing when crepiness is the main concern.

But significant loose skin is different from mild crepiness.

Salmon DNA injections shouldn’t be marketed as an alternative to eyelid surgery when substantial skin laxity is present.

Can Salmon DNA Help Dark Circles? #

It depends on what is causing your dark circles.

“Dark circles” isn’t one diagnosis.

The under-eye area may look dark because of:

• Pigmentation
• Visible blood vessels
• Thin skin
• Tear-trough shadows
• Facial anatomy
• Volume loss
• Lifestyle factors

Improving skin quality may make some under-eye concerns appear better, particularly when thin or poor-quality skin is contributing.

But salmon DNA isn’t a universal treatment for dark circles.

If pigmentation is causing the darkness, you may need a pigmentation-focused treatment.

If deep hollowness is creating a shadow, improving skin quality alone may not correct the structural problem.

Can Salmon DNA Fix Under-Eye Hollows? #

This is where expectations become especially important.

Polynucleotide injections aren’t traditional tear-trough filler.

Hyaluronic acid filler provides physical volume and can be used in carefully selected patients to address structural hollowness.

Polynucleotides primarily target skin quality.

A 2026 review comparing the two concluded that hyaluronic acid remains better suited to structural correction, while polynucleotides show benefits for dermal quality such as hydration, elasticity, and fine lines. (PubMed)

So if your main problem is a deep tear trough, salmon DNA may not provide the correction you’re expecting.

Salmon DNA vs Under-Eye Filler #

The easiest way to understand the difference is:

Salmon DNA/PN ? improves skin quality

Under-eye filler ? addresses selected structural volume deficits

Neither is automatically better.

They treat different problems.

If your under-eye skin is thin and crepey but you don’t have significant hollowness, adding filler may not address your primary concern.

Likewise, if you have substantial structural hollowing, improving skin quality alone may not eliminate the shadow.

This is why the under-eye area needs to be evaluated rather than automatically treated.

Salmon DNA vs Botox Around the Eyes #

These treatments also have different purposes.

Botox and other neuromodulators reduce targeted muscle activity.

That’s useful for dynamic crow’s feet created when you smile or squint.

Polynucleotides don’t relax those muscles.

Instead:

Botox ? movement

Polynucleotides ? skin quality

If someone has both strong crow’s feet and crepey skin, those are two different components of aging and may require different approaches.

Salmon DNA vs Microneedling Under the Eyes #

Microneedling stimulates collagen remodeling by creating controlled micro-injuries.

Polynucleotide injections take a different regenerative approach.

If the primary concern is thin, dehydrated, crepey-looking skin, polynucleotides may be considered.

If texture and collagen remodeling are bigger concerns, microneedling may have a role.

Treatment around the eyes requires particular caution because of the delicate anatomy.

How Many Under-Eye Salmon DNA Treatments Are Needed? #

There isn’t one universally established protocol.

Some professional guidance describes courses of approximately two to three sessions, while individual clinical studies have used different treatment schedules. (EyeWiki)

Your treatment plan should depend on:

• Starting skin quality
• Degree of fine lines
• Crepiness
• Treatment goals
• Specific product
• Individual response

More treatments aren’t automatically better.

Your skin should be reassessed to determine whether additional treatment is worthwhile.

When Do You See Results? #

Don’t expect the final result immediately after treatment.

In fact, the under-eye area may temporarily look worse before it looks better because injections can cause:

• Small bumps
• Swelling
• Redness
• Tenderness
• Bruising

These initial reactions generally settle.

The actual skin-quality changes are more gradual. Research has reported improvements developing over the following weeks and months. (EyeWiki)

This isn’t an instant transformation.

How Long Is the Downtime? #

Polynucleotide injections generally have relatively limited downtime, but limited downtime doesn’t mean zero downtime.

Localized swelling, redness, bruising, and small injection-site bumps can occur. EyeWiki notes that redness and swelling commonly decrease within about 24–48 hours, although individual recovery varies. (EyeWiki)

The under-eye area can also swell more noticeably because of its delicate anatomy.

If you have an important event, photographs, or wedding coming up, don’t schedule your first treatment immediately beforehand.

Are Salmon DNA Injections Under the Eyes Safe? #

Available research suggests polynucleotide injections are generally well tolerated, with reported side effects most often being mild, temporary injection-site reactions. A systematic review of nine studies involving 219 patients found generally mild and transient side effects, but also concluded that the evidence remains limited and higher-quality studies are needed. (PubMed)

A more recent observational study specifically involving the under-eye area reported minimal adverse events and no delayed complications during follow-up, but because it included only 42 patients and lacked a control group, it cannot establish the complete safety profile. (PubMed Central (PMC))

And the location matters.

The area surrounding the eye contains important blood vessels and delicate anatomical structures. Any injectable treatment in this region should be performed by an appropriately qualified healthcare professional who understands periorbital anatomy and complication management.

Who May Not Be a Good Candidate? #

Not everyone should receive polynucleotide injections.

Factors that may require avoiding treatment or additional medical assessment include active infection in the treatment area, certain bleeding risks, pregnancy or breastfeeding, and potential hypersensitivity concerns depending on the product. Fish allergy is also an important consideration with salmon-derived products. (EyeWiki)

The exact contraindications depend on the specific product being considered.

What U.S. Patients Should Know #

This is especially important.

“Salmon DNA” doesn’t describe one standardized FDA-approved treatment.

Products marketed as:

PDRN

PN

Polynucleotides

Rejuran

Salmon DNA

may not be equivalent.

A product available or approved for aesthetic injection in another country shouldn’t automatically be assumed to have the same regulatory status in the United States.

Before receiving treatment, ask your provider:

• What exact product are you using?
• Who manufactures it?
• Where was it obtained?
• Is it intended to be injected?
• What is its current U.S. regulatory status?
• Why is it appropriate for my particular under-eye concern?

The exact product matters much more than the phrase “salmon DNA.”

So, Can Salmon DNA Be Injected Under the Eyes? #

Yes. Certain purified polynucleotide and PDRN products are used internationally for injectable periorbital rejuvenation, and emerging clinical research suggests potential improvements in under-eye fine lines, hydration, elasticity, and overall skin quality. (PubMed)

But it isn’t the answer to every under-eye problem.

If you have crepey, thin, dehydrated-looking under-eye skin, a regenerative skin-quality treatment may be worth discussing.

If your main concern is deep hollowness, pigmentation, prominent bags, or significant loose skin, another treatment may be more appropriate.

The goal shouldn’t be to inject something under your eyes because it’s trending.

The goal is to identify why your under-eye area looks different and choose the treatment that actually addresses that problem.

A Skin-Forward Approach at AIVI Aesthetics #

At AIVI Aesthetics, we don’t assume every tired-looking under-eye needs filler.

Sometimes the problem is volume.

Sometimes it’s pigmentation.

Sometimes it’s muscle movement.

And sometimes it’s simply that the skin has become thinner, drier, and more crepey with age.

We evaluate the under-eye area and your overall skin quality before recommending treatment.

Depending on your concern, your treatment plan may involve regenerative skin treatments, microneedling, RF microneedling, neuromodulators, professional skincare, or another approach.

Our goal is to help you look refreshed and healthy while still looking like yourself—not overdone.
