Could Rejuran suit your under-eye concern?

The under-eye area is often one of the first places clients notice premature ageing.

You may find that concealer no longer sits as smoothly as it once did. The skin might look finer or more crepey, or you may feel that your eyes look tired even when you are well rested.

Rejuran is one treatment you may have heard about for this area.

But before I recommend it, there is something I always want to establish first: what is actually creating the change beneath your eyes?

Because “tired eyes” can mean several different things.

Not All Dark Circles Are the Same

Darkness beneath the eyes may be related to pigmentation, visible vessels, fine translucent skin or shadowing from a hollow.

Puffiness can also change the way light falls across the area. And for many clients, more than one of these things is happening at the same time.

This is why I do not treat every dark circle in the same way.

If the darkness is coming from pigmentation, improving the skin texture may not change the colour. If a hollow is creating the shadow, Rejuran cannot rebuild the structural support beneath it. And if puffiness is the main concern, adding treatment to the area may not give you the refinement you are looking for.

The first step is understanding which concern we are actually treating.

Rejuran

Rejuran is an injectable sodium-polynucleotide gel administered through a series of small injections into the skin.

It is something I consider when the skin itself is part of the concern—particularly when it appears fine, crepey or less resilient.

Research into polynucleotide treatments has reported changes in measures such as hydration, elasticity and surface texture. The evidence is still developing, and studies vary in the products, protocols and outcome measures they use.

Rejuran is not a conventional volumising treatment. It does not replace significant volume loss or reconstruct a pronounced tear trough.

Could Rejuran suit you?

Potentially, if skin quality is the main concern.

I particularly consider it when a client is bothered by fine texture or crepiness rather than significant hollowing or puffiness.

But if the concern is mainly caused by pigmentation, prominent fat pads, fluid retention or a structural hollow, I would be more cautious. Those concerns need a different conversation.

Skin Texture and Hollowing Are Not the Same Thing

This is one of the most important distinctions in the under-eye area.

Fine skin can make the area look less smooth and resilient. A hollow is different. It may relate to bone structure, fat distribution, midface volume or the relationship between the lower eyelid and cheek.

Puffiness is different again.

It can be tempting to treat everything beneath the eye as one concern, but this can lead to unnecessary treatment in an area where small changes are highly visible.

Sometimes Rejuran is appropriate. Sometimes another treatment makes more sense. And sometimes the best decision is to leave the area alone.

What Is the Treatment Like?

Rejuran is administered using multiple small injections across the selected treatment area.

Immediately afterwards, you may see small raised points where the product has been placed. Redness, swelling, tenderness and bruising can also occur.

Clients often ask me if there is any downtime.

I prefer not to simply call it “minimal.” The raised points and redness are generally temporary, but the area beneath the eyes is difficult to hide. Swelling or bruising that might be easy to overlook elsewhere can feel much more noticeable here.

If you have work, photographs or an important event approaching, this is something worth planning for.

Any change in skin quality develops gradually. Rejuran is not intended to create an immediate volumising effect, and the number and spacing of treatments should be guided by the condition of your skin and how it responds.

When Would I Be Cautious?

I would be cautious about recommending Rejuran when the main concern is:

• significant structural hollowing;

• prominent under-eye fat pads;

• recurrent puffiness;

• marked tissue laxity;

• pigmentation without a skin-quality concern;

• poor lower-eyelid support; or

• an active medical or inflammatory condition.

Where the under-eye concern is connected to broader facial laxity or structure, I may consider it as part of a more complete ageing treatment plan.

Treatments such as Ultraformer and EMFACE have different purposes. They are not direct substitutes for Rejuran, and I would not add them simply to create a more extensive plan.

Good treatment is not about doing the most.

It is about knowing what will—and will not—address the concern.

Risks and Medical Screening

Possible effects include pain, tenderness, redness, swelling, raised injection points, bruising, itching, local irritation and temporary asymmetry while swelling settles.

Less common complications may include infection, inflammatory or hypersensitivity reactions, persistent swelling, nodules, discolouration or unintended effects involving nearby structures.

Severe or increasing pain, marked discolouration, visual disturbance, breathing difficulty or signs of infection require urgent medical attention.

Rejuran is an animal-derived product. Relevant allergies, medication, medical conditions and previous procedures need to be discussed before treatment. Pregnancy, breastfeeding and active infection also require consideration.

There Is No Single Treatment for “Tired Eyes”

There is the treatment that is right for your skin, your anatomy and the concern you want to address.

Sometimes that may be Rejuran. Sometimes it may be another approach. And sometimes, after looking closely at the area, I may advise you not to treat it.

You do not need to know which category your under-eye concern falls into before coming to see me. That is what the assessment is for.

A consultation with Dr Shammi can clarify what is creating the change and whether Rejuran has a meaningful role.

REJURAN is an injectable sodium-polynucleotide gel intended for injection into the mid-to-deep dermis to promote tissue restoration and reconstruction and improve physical appearance, including around the eyes. REJURAN is an animal-derived Class III medical device included in the Australian Register of Therapeutic Goods (ARTG 412630).
