Rejuran Downtime: How Many Days to Recover? Real Progress from Embossing to Bruising

Many people are taken aback when they look in the mirror after receiving Rejuran and see bumpy embossing on their skin. To cut to the chase, most Rejuran downtime visibly subsides in 1 to 3 days. The most characteristic embossing usually takes from several hours to 1 to 3 days at most, redness takes 2 to 3 days, and swelling takes about 1 to 3 days. Only if bruising occurs can it last 3 to 7 days, and in severe cases, up to 2 weeks.

However, there are variations depending on the individual, the area treated, and your condition on that day. Therefore, rather than just memorizing a specific number of "days," you will feel much more at ease if you understand the flow of what symptoms occur, why, and when they disappear. Based on the questions we frequently receive at Gangnam Onlif Clinic, we will summarize the beginning to end of Rejuran downtime.

🧬 What is Rejuran downtime?

Rejuran is a skin booster treatment that injects Polynucleotide (PN), derived from salmonids, into the dermis layer. It is a product line manufactured by the domestic company **PharmaResearch**, and includes the representative Rejuran Healer, as well as Rejuran I (specifically for under the eyes), HB, and S.

Downtime is a natural reaction of the skin while this PN settles into the dermis. Embossing is a temporary shape created when the injected drug remains on the skin surface before it is absorbed; it is not a sign of a problem.

Typical downtime symptoms include:

• Embossing (wheal): bumpy protrusion, several hours to 1-3 days

• Redness: several hours to 2-3 days

• Swelling: 1-3 days

• Bruising: 3-7 days, up to 2 weeks in severe cases

• Fine scabbing/needle marks: 2-5 days

• Stinging: temporary immediately after treatment

📌 Key Summary: Rejuran downtime is a normal reaction of PN being absorbed into the dermis, and embossing, redness, and swelling mostly subside within 1 to 3 days.

⏱️ How does it change over time?

It is easier to prepare yourself mentally if you look at the progression chronologically rather than looking at a chart of numbers. You can think of the flow like this.

The effects of Rejuran are not immediate. There is a period when the area may actually look slightly hollow as the swelling goes down, but this is a natural process, not a failure. It takes several weeks for PN to reorganize the collagen environment. Saying "swelling is the effect" is close to a misunderstanding.

📌 Key Summary: Embossing is prominent immediately after, swelling and bruising stand out the next day, and most surface reactions subside in 2 to 3 days.

💉 Does downtime differ by injection method and area?

Even for the same Rejuran treatment, the patterns of marks or bruising may differ slightly depending on whether hand injection (manual injection) or the automatic injector method is used. Injections by hand leave distinct injection points, whereas injectors spread the drug evenly but may leave wider fine marks. It is not a matter of one being absolutely better, but rather a choice based on the area and purpose.

There are also significant differences depending on the area. The thin skin under the eyes (Rejuran I) is relatively prone to bruising and swelling, which is easily visible. Thick skin areas like the cheeks and forehead recover relatively smoothly. Therefore, we recommend allowing for a more flexible schedule for under-eye treatments.

The layer being injected is the dermis. If the injection depth is shallow, the embossing becomes more prominent, which naturally resolves as it is absorbed. An anesthetic cream is applied before the treatment to relieve pain, and including this process, the treatment time takes approximately 30 minutes to an hour.

📌 Key Summary: Downtime under the eyes may feel longer, and embossing and bruising patterns vary depending on the injection method and injection depth.

🔍 How does it compare to other treatments and downtimes?

Rejuran is often compared to fillers or lasers. Since their purposes and mechanisms differ, the nature of their downtime is also different.

Rejuran is not a treatment that fills something, but rather one that refines the skin's environment itself. That is why some people come expecting volume and feel like "it didn't make much of a difference," but understanding the nature of this treatment will reduce such misunderstandings.

📌 Key Summary: Rejuran is a skin texture improvement treatment rather than a filling treatment, and its purpose and downtime patterns differ from fillers and lasers.

🧊 How can you reduce downtime?

The length of downtime depends as much on pre- and post-care as it does on the treatment itself. Especially for bruising, there are many things you can do in advance.

Things to consider before treatment:

• Do not stop taking aspirin or anticoagulants arbitrarily; consult beforehand.

• Omega-3 and Vitamin E can thin the blood and increase bruising, so adjust intake several days prior.

• You tend to bruise easily before and after your period, so a flexible schedule is recommended.

• Be sure to inform us in advance if you have a history of fish allergies.

Things to consider after treatment:

• Alleviate swelling and bruising with a cold compress immediately after, then switch to a warm compress once the bruise's color has settled.

• Washing your face and applying makeup is typically allowed after 12-24 hours (hospital guidelines take priority).

• Avoid drinking alcohol for at least 24-48 hours, and avoid strenuous exercise for 24-48 hours.

• Avoid saunas and bathhouses for 2-3 days or more.

• Do not pick at scabs, and prevent hyperpigmentation by protecting your skin from UV rays.

Scratching scabs or leaving them exposed to UV rays can leave hyperpigmentation. If it has already occurred, it is better to manage it by focusing on protection and soothing rather than trying to force it away, and then watch the progress.

📌 Key Summary: To reduce bruising, adjust blood-thinning medications and supplements beforehand, and apply a cold compress and UV protection immediately after.

📅 When should you get it before an important event?

If you have an important day where your face matters, such as a wedding, a photoshoot, or a formal meeting between families, you need to calculate. This is because although embossing and redness clear up in 1 to 3 days, bruising can last up to 2 weeks.

Therefore, we recommend leaving a margin of at least 1 week, or 2 weeks if it is your first time receiving the treatment. It is difficult to predict how your skin will react during your first treatment. If it is a highly visible area like under the eyes, allow even more time.

Rejuran is not a one-time treatment; the skin texture is gradually refined when received in a series of 3 to 4 sessions at 2 to 4-week intervals. Rather than rushing it all at once, planning it out according to your schedule makes both the results and downtime management easier.

📌 Key Summary: Allow at least 1 week before important days, and 2 weeks or more if it is your first treatment, and plan Rejuran in a series of 3 to 4 sessions.

⚠️ What symptoms warrant an immediate visit to the clinic?

Time resolves most downtimes. However, the following are signals that must be distinguished from simple downtime.

• When the skin turns pale or discolors into a net-like pattern

• Severe pain, blistering, or changes where the tissue seems to be damaged

• Blurred vision or eye pain after treatment around the eyes

• Swelling that worsens over time, heat sensation, or suspected infection such as pus

• Nodules that remain palpable and do not subside

Although these symptoms are rare, there is a possibility of vascular complications, so it is safer to contact the clinic where you received treatment immediately rather than making a self-judgment.

📌 Key Summary: Paleness, net-like discoloration, blurred vision, and worsening pain are not simple downtimes, so contact the clinic without delay.

🌿 Onlif Clinic's Perspective

Onlif Clinic does not aim for treatments that change the shape of the face, but rather pursues a direction that clears away skin concerns that mask your natural beauty. Skin boosters like Rejuran refine hydration, the skin barrier, and texture, and when elasticity is needed, we design the treatment plan alongside ultrasound HIFU, radiofrequency RF, or lifting procedures.

Operating under the philosophy that "one doctor cannot be good at everything," Onlif has built trust by dividing and assigning treatments to the doctors who perform them best in each field. Concerns about downtime are ultimately resolved by designing a plan that fits your skin and schedule.

Even with the same Rejuran, the course of recovery varies depending on the area, skin thickness, and medications taken. An accurate determination is made through a consultation after directly examining your skin condition.

❓ Frequently Asked Questions (FAQ)

When does Rejuran embossing disappear?

Most of it subsides within several hours to 1 to 3 days. If injected shallowly, it may be felt a bit longer, but it will clear up naturally as it is absorbed, so do not rub it forcibly.

Can I go to work the day after the Rejuran treatment?

Embossing and redness may remain, but they can be covered to some extent with makeup. However, if bruising has occurred, it may be visible for a few more days, so if you are going to a place where you are conscious of it showing, it is better to allow some margin.

When can I wear makeup and wash my face after Rejuran?

It is usually recommended 12 to 24 hours after the treatment, and clinic guidelines take priority. In the beginning, manage gently without rubbing.

Is bruising normal after Rejuran? How long does it last?

Since it is an injection treatment, bruising is a common reaction. It usually lasts 3 to 7 days, and up to 2 weeks in severe cases. A cold compress immediately after, followed by a warm compress, helps with recovery.

When can I drink, exercise, and go to the sauna after Rejuran?

It is recommended to avoid drinking and strenuous exercise for at least 24 to 48 hours, and to avoid saunas and bathhouses for 2 to 3 days or more. Stimulating blood flow can worsen swelling and bruising.

If I have a fish allergy, should I not get Rejuran?

Since Rejuran is a salmon-derived ingredient, you must inform us in advance if you have a history of fish allergies. Whether the treatment can be performed is determined through consultation.

Is the downtime longer for Rejuran I (under the eyes)?

The skin under the eyes is thin, making bruising and swelling more likely to occur and be visible. It is safer to set a more generous recovery period than for normal areas.

What symptoms after Rejuran require an immediate visit to the clinic?

Pale skin, net-like discoloration, blurred vision, progressively worsening pain/swelling, and symptoms of suspected infection may not be simple downtimes, so contact the place where you received treatment immediately.
