Rejuran Downtime: Recovery Timeline, Side Effects & Aftercare

Rejuran is an injectable skin rejuvenation treatment used by people who want to improve aspects of skin quality without dramatically changing their facial shape or expressions. Although it is often described as a treatment with minimal downtime, the skin may not look completely normal immediately after the appointment.

Small injection bumps, redness, tenderness, swelling and occasional bruising can appear after treatment. These reactions are generally temporary and are associated with the multiple injections used to place the product within the skin. However, recovery varies from person to person, and no injectable treatment is completely risk-free.

So, how long does Rejuran downtime last? When can you return to work, wear makeup, exercise or attend an important event? This guide explains what you may experience during the first few hours and days after treatment, along with practical aftercare advice and signs that require medical attention.

What Is Rejuran and How Does It Work?

Rejuran is an injectable treatment associated with polynucleotides (PN). It is used in aesthetic practice to address selected skin-quality concerns. The treatment involves placing small amounts of product into the skin using multiple injections.

Rejuran is not simply a topical skincare product, and its effects should not be confused with those of conventional dermal fillers. The intended outcome depends on the specific formulation, treatment area and individual treatment plan.

Because Rejuran involves injections into the skin, temporary injection-site reactions can occur even when the procedure is performed appropriately. Understanding these possible reactions helps you plan your recovery realistically.

How Long Is Rejuran Downtime?

For many patients, the most noticeable Rejuran downtime lasts approximately one to three days. During this period, small raised bumps at the injection points, mild redness or puffiness may remain visible.

Recovery is not identical for everyone. Some people look relatively settled the following day, while others may experience visible swelling or bruising for several days. Published research involving polynucleotide injections has reported temporary local reactions, with recovery times varying according to the symptom and individual response.

A practical way to think about recovery is:

Allow more recovery time if you are treating a larger area, the delicate under-eye region or multiple areas during one session. If you have an important event, it is safer not to assume that all visible signs will disappear within 24 hours.

What Does the Skin Look Like Immediately After Rejuran?

Immediately after treatment, the skin may look red, slightly swollen and covered with small raised injection points. These bumps are sometimes described as tiny mosquito bites.

They appear because Rejuran is delivered through multiple small injections rather than applied to the skin’s surface. The number, height and visibility of these bumps can vary according to the treatment area, injection depth, product volume and technique used by the practitioner.

You may also notice:

These immediate reactions do not indicate the final result of your treatment. The appearance of the skin immediately after injections is different from the longer-term changes the treatment is intended to address.

A Day-by-Day Rejuran Recovery Timeline

The First Few Hours

The injection bumps are generally most visible immediately after the procedure. Your face may appear puffy, flushed or uneven, particularly when a larger number of injections have been used.

Mild stinging or tenderness may continue after the numbing cream wears off. Some people also experience a warm sensation around the treated area.

Avoid pressing, rubbing or repeatedly touching the skin unless your practitioner has specifically instructed you otherwise. Follow the aftercare instructions provided by the clinic.

The First Night

By the evening, redness may begin to settle, although raised injection points can remain noticeable.

Swelling may be more apparent around the eyes because the skin in this area is thin and delicate. Sleeping on your back with your head slightly elevated may help minimise pressure against the treated area.

Mild swelling can fluctuate during the first 24 hours. However, rapidly worsening swelling, severe pain or other unusual symptoms should not be dismissed as normal recovery.

The Next Morning

Many patients still have visible bumps or puffiness the morning after Rejuran. Some injection points may look like tiny red dots, while others may appear skin-coloured.

The face may also feel slightly tender when cleansing or applying skincare. Use gentle movements rather than scrubbing or massaging the skin.

This can be the main period of social downtime. You may feel physically able to work, but injection marks might still be visible during face-to-face meetings or photographs.

Days Two to Three

The raised bumps and redness should gradually become less noticeable during this period, although the timing varies. Mild puffiness may remain, particularly beneath the eyes or in areas where more product was placed.

Small bruises may become more noticeable as swelling subsides. This does not necessarily mean the treatment has become worse; bruising can change colour as it heals.

Many patients feel comfortable returning to their usual social routine during this stage, but allow more time if visible marks remain.

Days Four to Seven

Most temporary injection marks should have settled considerably. Any remaining downtime is more likely to involve isolated bruising, mild tenderness or lingering swelling.

Some people recover sooner, while others need longer. Contact your practitioner if symptoms are not improving, are becoming more painful or look significantly different from the recovery guidance you were given.

The Most Common Rejuran Side Effects

Small Injection Bumps

Temporary raised bumps are one of the most recognisable parts of Rejuran downtime. These papules form at the injection points and can make the skin look textured or uneven.

They should gradually flatten as the skin settles. Their visibility may depend on how superficially the product was injected and the amount placed at each point.

Do not squeeze, scratch or press the bumps in an attempt to flatten them faster.

Redness

Mild redness is a common response to the needle entering the skin. It may be concentrated around each injection point or spread more generally across the treatment area.

Redness should gradually become less noticeable rather than continuously intensifying. Persistent redness accompanied by heat, increasing pain or discharge should be assessed by a healthcare professional.

Swelling

Swelling may be mild and localised or more noticeable across the treated area. It can be particularly visible around the eyes.

The degree of swelling varies according to the treatment area, injection technique and individual response. Rapidly worsening or painful swelling should be reported promptly to your practitioner.

Bruising

A needle can occasionally affect a small blood vessel, creating a bruise. Bruising may not appear immediately and can become darker the day after treatment.

People who bruise easily or take certain medications may experience more visible bruising. Never stop prescribed blood-thinning medication without speaking to the healthcare professional who prescribed it.

Tenderness or Mild Pain

Mild soreness, stinging or sensitivity may occur around the injection points. The discomfort should generally become less intense as the skin settles.

Severe, escalating or unusual pain is not something to ignore and should be reported promptly.

Itching or Firmness

Some people may notice mild itching or small areas of temporary firmness after treatment. Avoid scratching the area, as this can irritate the skin and introduce bacteria.

If itching is severe, swelling is worsening or the area becomes increasingly painful, contact your practitioner for advice.

How to Reduce Rejuran Downtime

Your practitioner’s instructions should always take priority because aftercare can vary according to the product, injection method and treatment area.

General aftercare advice for injectable treatments commonly includes avoiding strenuous exercise for a short period and limiting excessive heat exposure during early recovery. Your clinician should advise when to resume your normal skincare routine and activities.

You may support a smoother recovery by:

A wrapped cool compress may sometimes be used to ease swelling, but do not place ice directly against the skin or apply heavy pressure. Ask your practitioner whether a cool compress is appropriate for your treatment.

Skincare During Recovery

Keep your skincare routine simple while the injection points settle. A gentle cleanser and a well-tolerated moisturiser may be appropriate once your practitioner confirms that you can resume them.

Avoid introducing new products or using potentially irritating ingredients, such as exfoliating acids or retinoids, until your practitioner advises that it is appropriate to do so. The timing may depend on your skin condition and treatment protocol.

Maintain adequate hydration and use sun protection as advised. These steps support general skin care, but they should not be presented as a guarantee of faster healing or better treatment results.

Can You Wear Makeup After Rejuran?

Your provider may advise waiting until the injection points have closed before applying makeup. This helps reduce unnecessary contact with freshly treated skin.

When you are cleared to use makeup:

Do not use makeup to cover an area that is bleeding, weeping or unusually irritated.

Because protocols differ, follow the specific timing provided by your treating clinic rather than relying on a universal rule.

Can You Wash Your Face After Rejuran?

Your practitioner will tell you when and how to cleanse your skin after treatment. Once cleansing is permitted, use clean hands, lukewarm water and a gentle cleanser.

Avoid hot water, scrubs, cleansing brushes and vigorous rubbing during the early recovery period. Pat the skin dry gently rather than rubbing it with a towel.

If your skin is becoming increasingly painful, hot or irritated, contact your practitioner before adding new skincare products.

Can You Exercise After Rejuran?

Light walking is generally less demanding than strenuous exercise, but intense workouts may increase facial warmth, sweating and swelling.

Your practitioner may recommend avoiding strenuous exercise for approximately 24 hours or longer, depending on the treatment and your recovery.

Activities to postpone during the recommended recovery period may include:

Resume exercise according to your practitioner’s instructions, especially after under-eye treatment or when you have significant bruising.

When Should You Schedule Rejuran Before an Event?

Do not arrange your first Rejuran appointment immediately before a wedding, professional photoshoot, important presentation or other event where you want your skin to look settled.

Although many people recover quickly, it is impossible to guarantee that you will have no bruising or swelling. A conservative approach is to leave at least one to two weeks between treatment and an important event, particularly when:

This provides a buffer for unexpected bruising and allows the skin to look more settled. Your own recovery may be shorter or longer.

What Is Not Considered Normal After Rejuran?

Mild redness, tenderness and puffiness can occur after treatment, but symptoms should generally improve with time.

Contact your practitioner promptly if you experience:

Hot, swollen and painful skin, pus and fever can be signs of a skin infection and require medical assessment.

Seek urgent medical help for visual disturbances, loss of vision or severe pain after a facial injectable procedure. Do not wait for these symptoms to resolve on their own.

Does More Downtime Mean Better Rejuran Results?

More swelling or more visible bumps do not automatically mean the treatment will produce a better result. Similarly, having very little downtime does not mean the treatment has failed.

The amount of downtime can be influenced by:

Recovery reactions and longer-term skin changes are separate issues. The presence or absence of injection bumps should not be used on its own to judge treatment effectiveness.

Clinical evidence on polynucleotide injectables is still developing. Discuss the expected benefits, limitations, potential complications and available alternatives with a qualified medical practitioner before treatment.

Frequently Asked Questions About Rejuran Downtime

Can I go to work the day after Rejuran?

Many people can physically return to work the next day. However, injection bumps, redness or swelling may still be visible. Working from home for one or two days may be preferable when appearance is important.

How long do Rejuran injection bumps last?

They commonly improve during the first few days, but the exact timing depends on the injection technique, treatment area and individual response. Contact your provider if bumps are painful, inflamed or not gradually settling.

Is swelling under the eyes normal after Rejuran?

Some temporary puffiness can occur after injections around the eyes. Because this area is delicate, swelling may look more noticeable than it does elsewhere. Rapidly worsening, painful or one-sided swelling should be assessed.

How long can Rejuran bruising last?

Small bruises may remain visible after the other injection marks have settled. Healing time varies depending on the size of the bruise, the treatment area and your tendency to bruise.

Can I wash my face after Rejuran?

Your practitioner will tell you when and how to cleanse your skin. Once permitted, use clean hands, lukewarm water and a gentle cleanser. Avoid hot water, scrubs, cleansing brushes and vigorous rubbing during early recovery.

Can I wear makeup 24 hours after Rejuran?

It depends on the condition of your skin and your practitioner’s instructions. Wait until you have been advised that it is safe and the injection points have closed. Avoid makeup on skin that is bleeding, weeping or unusually irritated.

Is Rejuran downtime worse after full-face treatment?

Full-face treatment may create more visible injection points than treating one small area. This can increase social downtime even when discomfort remains mild.

When will I see Rejuran results?

The time needed to notice changes varies according to the product, treatment plan and individual response. Immediate injection bumps and swelling are part of the recovery phase and do not represent the final result. Ask your practitioner when to assess your progress and whether additional sessions may be appropriate.

Can Rejuran be combined with other treatments?

Some treatment plans may include more than one procedure, but combining treatments is not appropriate for everyone. Your practitioner should assess the timing, suitability, risks and expected benefits before recommending a combination.

Final Thoughts

Rejuran downtime is usually manageable, but it is important to have realistic expectations. The treatment can temporarily leave your skin with raised injection bumps, redness, tenderness, swelling or bruising.

For many patients, the most visible effects improve within one to three days. However, some reactions can last longer, especially bruising or swelling around the eyes. Individual recovery varies, and no injectable treatment is completely risk-free.

Choose an appropriately qualified medical practitioner, follow the aftercare instructions carefully and contact the clinic when your recovery does not follow the expected pattern.
