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

When you look in the mirror after receiving Rejuran, many people are startled to see bumpy embossing on their skin. To put the conclusion first, Rejuran downtime mostly subsides noticeably within 1 to 3 days. The most characteristic embossing takes several hours to 1 to 3 days at most, redness takes 2 to 3 days, and swelling takes about 1 to 3 days as a general progress. Only in cases where bruising occurs can it last 3 to 7 days, or up to 2 weeks in severe cases.

However, there are variations depending on the person, the area, and the condition of that day. Therefore, rather than just memorizing the number of "days," it is much more comforting to understand the flow of what symptoms occur, why, and when they disappear. Focusing on the questions we actually receive a lot at Gangnam Onlif Clinic, we will summarize Rejuran downtime from beginning to end.

🧬 What is Rejuran downtime?

Rejuran is a skin booster line treatment that injects Polynucleotide (PN), derived from salmonid fish, into the dermis layer. It is a product line made 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 as this PN settles into the dermis. Embossing is a temporary form created when the injected drug remains on the skin surface before being absorbed; it is not a signal of a problem.

Typical downtime symptoms are as follows:

• Embossing (wheal): bumpy bulging, 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 scabs/needle marks: 2–5 days

• Stinging: temporary immediately after the treatment

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

⏱️ How does it change hour by hour?

Rather than a table of numbers, looking at it chronologically makes mental preparation easier. You can think of it as a flow like this.

The effects of Rejuran are not immediate. As the swelling subsides, there is a period when the skin actually looks slightly hollow, 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 surface reactions mostly subside in 2 to 3 days.

💉 Does downtime differ depending on the injection method and area?

Even with the same Rejuran, the pattern of marks or bruising may vary slightly depending on whether hand injection (manual injection) or the automatic injector method is used. Injecting stitch-by-stitch by hand leaves distinct injection points, while the injector spreads the product evenly but may leave wider fine marks. It is not a matter of one being absolutely better, but rather a choice made based on the area and purpose.

There are also major differences by area. The under-eye area (Rejuran I), where the skin is thin, is relatively prone to bruising and swelling, which are easily visible. On the other hand, recovery is relatively smooth in areas with thicker skin, such as the cheeks and forehead. Therefore, we recommend allowing a bit more margin in your schedule for under-eye treatments.

The layer being injected is the dermis. If the injection depth is shallow, the embossing becomes more prominent, and this naturally resolves as it is absorbed. An anesthetic cream is applied before the procedure to alleviate pain; including this step, the total treatment time is approximately 30 minutes to 1 hour.

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

🔍 How does downtime compare to other procedures?

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 to fill something, but rather closer to refining the skin's environment itself. Thus, some who come expecting volume might feel "it doesn't make much of a difference," but understanding the nature of this treatment will reduce misunderstandings.

📌 Key Summary: Rejuran is a skin texture improvement treatment, not a filler, and differs from fillers and lasers in both its purpose and downtime patterns.

🧊 How can you reduce downtime?

The length of downtime depends as much on pre- and post-care as on the procedure itself. In particular, there are many things you can do in advance to manage bruising.

Things to check before the procedure

• Do not stop taking aspirin or anticoagulants arbitrarily; consult in advance

• Omega-3 and Vitamin E can thin the blood and increase bruising, so adjust them a few days prior

• Bruising occurs easily before and after menstruation, so scheduling on a flexible date is recommended

• Be sure to inform us in advance of any history of fish allergies

Things to check after the procedure

• Alleviate swelling and bruising with cold compresses immediately after, and switch to warm compresses once the bruise color has settled

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

• Avoid alcohol for at least 24 to 48 hours, and strenuous exercise is also prohibited for 24 to 48 hours

• Avoid saunas and bathhouses for at least 2 to 3 days

• Do not pick at scabs, and prevent pigmentation through UV protection

If you scratch scabs or expose them to UV light, hyperpigmentation may remain. If it has already occurred, rather than trying to force it off, it is better to manage it with protection and soothing care while watching its progress.

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

📅 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 family meeting, calculation is required. This is because while embossing and redness resolve 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 or more if you are receiving it for the first time. It is difficult to predict how your skin will react during the first treatment. If it is a highly visible area like under the eyes, set an even more generous timeline.

Rejuran is not a one-time treatment; the texture is gradually refined when received in a series of 3 to 4 sessions at 2 to 4-week intervals. Rather than rushing to do 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 for important events, 2 weeks or more for the first treatment, and plan Rejuran in a series of 3 to 4 sessions.

⚠️ What symptoms mean you should go to the clinic immediately?

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

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

• Severe pain, blistering, or changes as if tissue is being damaged

• Blurred vision or eye pain after procedures around the eyes

• Swelling, heat, or suspected infection like pus that worsens over time

• Nodules that do not subside and continue to be felt

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

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

🌿 The Perspective of Onlif Clinic

Onlif Clinic does not aim for procedures that alter the shape of the face, but rather pursues a direction that clears away skin concerns masking your natural beauty. Skin boosters like Rejuran are used for moisturization, skin barrier, and texture refinement, and when elasticity is needed, we design the treatment together with ultrasound HIFU, high-frequency RF, or lifting procedures.

Based on the philosophy that "one doctor cannot do everything well," dividing and assigning treatments to doctors who excel most in each field is also how Onlif has built trust. Anxiety about downtime also ultimately finds its answer in a design that fits my skin and schedule.

Even with the same Rejuran, the progress varies depending on the area, skin thickness, and medications taken. An accurate determination is made through a consultation after directly examining the 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 resolves naturally as it is absorbed, so do not rub it forcibly.

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

Since embossing and redness may remain, they can be covered to some extent with makeup. However, if bruising occurs, it may show for a few more days, so it is better to allow some margin if you are going to a place where being noticed is a concern.

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

It is usually recommended 12 to 24 hours after the procedure, and the clinic's guidance takes priority. Do not rub in the beginning, and manage gently.

Is bruising after Rejuran normal? 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. Cold compresses immediately after, followed by switching to warm compresses, help with recovery.

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

It is recommended to avoid alcohol and strenuous exercise for at least 24 to 48 hours, and 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 procedure is possible is determined through a consultation.

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

The under-eye area has thin skin, making bruising and swelling more likely to occur and be noticeable. It is safer to set a more generous recovery period than for general areas.

What symptoms after Rejuran require going to the clinic immediately?

Skin paleness, net-like discoloration, blurred vision, increasingly severe pain and swelling, or symptoms of suspected infection may not be simple downtime, so contact the clinic where you received the treatment immediately.

Rejuran Downtime, Things to Check Before Choosing a Clinic

Even for the same procedure, the results and recovery process differ depending on where, by whom, and how it is performed.

Asking these items directly during the consultation will help you make a decision.

• Is it a place that performs this procedure frequently? — Each clinic has different core procedures they focus on. Check if it is a place that regularly conducts Rejuran downtime procedures.

• Can I verify the products and equipment used? — Ask if you can verify the product name and authenticity (whether it is an import-approved product and if there is a process to confirm unboxing) during the consultation.

• Do they explain the cost breakdown? — Rather than just hearing the total amount, you need to hear an explanation of what product is used, how much, and on which areas to make a proper judgment.

• Do they design the treatment looking at the entire face? — Even for the same procedure, the injection locations and amounts differ depending on the face shape, skin condition, and left-right asymmetry.

• Do they explain adverse reactions and the recovery process first? — Rather than a consultation that only speaks of expected changes, a place that also informs you of possible adverse reactions and coping methods is better for making a decision.

• Is there a follow-up pathway after the procedure? — Check if the timeframe for checking progress, how to contact them if there is an anomaly, and the criteria for revisit are established.

Onlif Clinic Handles Rejuran Downtime This Way

• We divide responsibilities — Based on the philosophy that one doctor does not handle all procedures, Onlif divides and assigns medical treatments to doctors specialized in each field.

• We verify products and equipment together during the consultation — We guide you through the products used and the process of confirming unboxing during the consultation process.

• Costs are guided along with the plan after diagnosis — Since the area, dosage, and range differ for each person, we explain what costs how much together.

• We design by looking at the overall facial balance — Looking at the face through the three pillars of texture, balance, and signals of youth, we plan in a direction that cleanses the parts masking your natural impression rather than changing the shape.

• We speak of adverse reactions and the recovery process first — Along with the changes that can be expected, we guide you through individual differences, possible adverse reactions, and coping methods before the procedure.

• We look at the progress after the procedure together — If verification is needed during the recovery period, we guide you on revisits and contact pathways.

If you are contemplating Rejuran downtime, it is best to first check what is possible and what is difficult in your current state.
