How Long Do Swelling and Bruising Last After Rejuran? A Complete Aftercare Guide
Swelling and bruising after a Rejuran (skinbooster) treatment are usually just part of the natural recovery process—swelling typically subsides within 2 to 3 days, while bruising may gradually fade over 1 to 2 weeks. During this period, the key is to minimize irritation and focus on soothing, hydrating care. Below, we walk you through the recovery timeline and step-by-step home care methods.
After a Rejuran treatment, it's common to notice swelling, redness, or even small bruises at the treated area, which can be a bit unsettling. This is a natural reaction that occurs as fine needles inject the ingredients into the skin, and in most cases, it gradually subsides over time without any special intervention.
However, knowing in advance how long swelling and bruising typically last can help ease unnecessary worry and make the recovery period feel more comfortable.
Why Does Swelling and Bruising Occur? The Causes
Skinbooster treatments like Rejuran involve injecting ingredients into the dermis multiple times using fine needles. This process stimulates the skin's surface and capillaries, temporarily increasing blood flow and causing fluid to accumulate in the tissue—this is what causes the swelling.
Bruising occurs when tiny blood vessels are stimulated during the procedure, and its extent can vary depending on the location of the vessels and individual skin and vascular characteristics. Areas with shallow blood vessels, such as around the eyes or mouth, may show bruising more visibly.
Both swelling and bruising are simply part of the natural process of the treated area settling and stabilizing, so there's no need to worry too much.
Recovery Timeline: How Long Is Normal?
Right after treatment to Day 1: This is when redness and swelling are most pronounced at the treated area. The skin may feel slightly firm or bumpy to the touch, which is a natural response as the injected ingredients settle in place.
Day 2–3: In most cases, swelling noticeably decreases and redness gradually fades. If you have bruising, you may start to notice the color beginning to change during this period.
Day 4 to 1 week: Swelling has mostly disappeared, and any remaining bruising goes through a gradual color change from reddish to brown or yellow as it fades. This is a recovery phase when the skin barrier is stabilizing, making deep hydration care especially important.
1–2 weeks and beyond: Most bruising has naturally disappeared, and skin tone and texture return to a comfortable state. That said, recovery speed can vary depending on individual skin condition and the treated area, so there's no need to rush—just give it time.
Step-by-Step Home Care: How to Take Care of Your Skin
STEP 1. Right after treatment to Day 3: Since the skin is sensitive during this period, focus on soothing and barrier care. Use lukewarm water when washing your face and avoid rubbing. Activities that raise body temperature, such as saunas, steam rooms, or intense exercise, can prolong swelling, so it's best to avoid them for a few days. Consistent sun protection should also begin during this period.
STEP 2. Recovery phase from Day 4 onward: After swelling and redness have subsided, it's important to focus on deep hydration and texture care to help the skin return to a comfortable state. Providing sufficient moisture during this period can help maintain more comfortable skin condition going forward.
If bruising remains, the most important principle is to avoid touching or massaging the area and to let it fade naturally without additional stimulation.

Home Care Makes All the Difference in Post-Treatment Recovery
During the recovery phase starting on day 4, once the treated area has begun to stabilize, deep hydration care that thoroughly replenishes moisture can help maintain a comfortable skin condition. The Hydro Re-Boosting Cream is a STEP 2 product designed for the recovery phase (from day 4 onward) after skinbooster treatments, with ingredients like panthenol and niacinamide that support deep hydration and skin texture care. In clinical testing, it was shown to help manage skin texture, hydration, and redness when used for 2 weeks following chemical irritation (individual results may vary), making it worth considering as a finishing step in your post-treatment home care routine.

FAQ
- How long does bruising last after Rejuran?
- The severity and duration of bruising vary depending on individual skin and blood vessel characteristics, but in most cases the color starts to fade and disappears naturally within 1 to 2 weeks. It's best to avoid rubbing or massaging bruised areas and simply let them heal without extra stimulation.
- When does swelling go down after Rejuran?
- Swelling is usually most noticeable right after the treatment and on the first day, and it visibly decreases within 2 to 3 days in most cases. To prevent prolonged swelling, it helps to avoid saunas, intense exercise, and other activities that raise body temperature during this period, and to get plenty of rest.
- What's the first step for home care after Rejuran?
- For the first 3 days after treatment, focus on minimizing irritation and prioritizing soothing and barrier care. From day 4 onward, once swelling and redness have subsided, shifting to deep hydration and skin texture care can support a more comfortable recovery.
- Is it okay to wear makeup if I have bruising or swelling?
- Since the skin is in a sensitive state right after treatment, it's best to avoid color makeup for at least 1 to 2 days and let your skin rest. After that, it's recommended to ease back in gradually while monitoring your skin's condition.
- What should I do if swelling or bruising lasts longer than usual?
- Recovery speed can vary from person to person, but if swelling or bruising lasts longer than expected, or is accompanied by pain or a warm sensation, it's safer to contact the clinic where you received treatment to have your condition checked.
