After Rejuran treatment in Cheongdam, swelling and bruising are usually managed as temporary reactions that settle within 1 week.
The small raised bumps often called embossing also tend to disappear naturally in about 1 week.
However, timing varies by area and individual condition, so discussing it during consultation is safer.
➊What does the recovery period after Rejuran involve?
Recovery after Rejuran refers to the time during which swelling, bruising, and temporary small bumps settle.
Rejuran uses salmon-derived regenerative ingredients placed in superficial skin layers to encourage the skin's own capacity to improve.
Unlike a volumizing filler, it aims for gradual texture and elasticity changes rather than an immediate transformation, so reactions to the injections themselves are often most visible during the first few days.
The question patients most want answered is, ultimately, “How many days will this swelling and bruising last?”
The short answer is that most reactions noticeably settle within 1 week.
However, the perceived duration varies with the area, injection technique, and individual vascular and skin condition.
➋Swelling and bruising are different reactions
Swelling and bruising have different causes and should therefore be assessed with different timelines.
Swelling occurs as the ingredient settles in the skin and temporarily attracts moisture. It tends to be most apparent during the first day or two, then gradually subsides.
Bruising occurs when a needle contacts small vessels, so its extent varies with vessel distribution in the area.
Areas such as the eyes and mouth, where vessels are superficial and dense, tend to show bruising more readily than the cheeks or forehead.
The time for color to fade also varies considerably: some bruises fade within days, while others remain for about 1–2 weeks.
| Reaction | Main cause | Usual course |
|---|---|---|
| Swelling | Moisture response immediately after injection | Tends to ease within 1–3 days |
| Bruising | Irritation of small vessels | Several days to 1–2 weeks; varies by area |
| Raised bumps (embossing) | Temporary elevations as the ingredient settles | Tend to resolve naturally in about 1 week |
“Because swelling and bruising have different causes, judging them by the same standard can lead to misunderstandings about recovery speed.”
➌Why do small raised bumps appear?
Embossing refers to the temporary small surface elevations commonly seen after Rejuran.
As salmon-derived ingredients settle in superficial skin layers, they can be felt as small bumps; many patients describe a tiny grain-like texture when touching the area.
This is understood to relate to the ingredient's characteristics and often becomes noticeably less apparent in about 1 week.
However, the extent varies with treatment area, amount, and skin thickness; even the same area can feel different between people.
Surface changes are relatively more visible where skin is thin, such as around the eyes.
➍What should I do during recovery?
Recovery care is not particularly complicated.
Following a few precautions can help prevent prolonged swelling and bruising.
| Timing | Care guidance |
|---|---|
| Treatment day | Avoid makeup and exfoliating products; focus on gentle moisturizing |
| For several days | Postpone saunas, heated bathhouses, strenuous exercise, and alcohol; increased circulation may accentuate swelling or bruising |
| Throughout recovery | Avoid vigorous rubbing or pressure massage; indirect cold compresses may help early swelling, avoiding direct contact |
➎When to contact the clinic
Most swelling, bruising, and bumps resolve naturally without special measures, but occasionally a reaction needs clinical assessment.
Temporary swelling, bruising, pain, and pigmentation can occur after treatment. Because the ingredients are salmon-derived, fish allergies must be disclosed beforehand.
If swelling or pain worsens rather than decreases over time, warmth or redness becomes pronounced, or a firm lump remains after several days, contacting the clinic is safer than deciding to wait on your own.
Rare injection marks or nodular reactions may persist; if you notice these changes, having them assessed is advisable.
➏How recovery time informs our Rejuran recommendations in Cheongdam
I readily discuss Rejuran with people who want gradual texture and elasticity improvement rather than immediate volume change, and whose schedules allow temporary swelling and bruising during recovery.
It is also a relatively accessible option to discuss for texture concerns in thin areas such as around the eyes or mouth.
Conversely, if an important event is close and even slight residual swelling or bruising would be a problem, if there is a fish allergy, or if immediate volume is expected, I consider postponement or other approaches.
From a revenue standpoint, recommending immediate treatment may be advantageous, but I believe adjusting the date to allow recovery ultimately improves satisfaction for patients with tight schedules.
We choose timing and method after reviewing skin condition, allergy history, and upcoming plans together, while recognizing individual variation in the final response.
- ✓ Texture and elasticity goals: Allow time for recovery
- ✓ An important event is imminent: Adjust timing or discuss alternatives
- ✓ Fish allergy: Always disclose it before treatment
“Because Rejuran sends recovery signals rather than simply filling, the recovery process between treatment and results matters as much as the outcome.”
➐Answers to common questions
How many days does Rejuran recovery usually take?
Individuals vary, but visible reactions such as swelling and bruising often settle within 1 week.
Timing may differ with the area and personal condition, so it is best discussed during consultation.
Can makeup cover the small bumps?
Mild unevenness can sometimes be lightly covered, but makeup may irritate the skin. Avoid it on treatment day and use mainly non-irritating products from the following day.
What if bruising lasts a long time?
Most bruises fade within days, but some can remain for 1–2 weeks or longer depending on the area and vessel position.
If swelling is accompanied by increasing pain or warmth, contacting the clinic is safer.
When can I resume saunas or exercise?
Increased circulation immediately after treatment can make swelling or bruising more apparent, so avoiding saunas, strenuous exercise, and alcohol for several days is recommended.
The exact timing depends on individual condition, so seek guidance during consultation.
How should I use skincare during recovery?
On treatment day, avoid makeup and irritating exfoliating products and focus on gentle moisturizing.
If redness or sensitivity remains afterward, continuing non-irritating care for several more days is safer.
How will I receive recovery guidance?
After examining the skin and areas of concern, treatment is performed, followed by an explanation of possible recovery reactions and care.
I recommend having your condition assessed and receiving specific care instructions suited to it (individual variation applies).
Rejuran is less about filling a deficit than about allowing cells to respond and produce changes themselves.
The recovery period is the process of these recovery signals settling in; most reactions resolve naturally over time.
