Timeline

StageWhat clinics publishSourceChecked on
Same dayRejuran is injected as many small intradermal deposits, producing 40 to 60 raised bumps at the injection sites. Mild redness and occasional pinpoint bruising are common, and clinics ask patients not to touch, rub or apply makeup to the area for several hours.northbiomedical.com/articles/rejuran2026-10-31
Day 1 to 2The raised injection bumps flatten within 12 to 36 hours. Swelling and redness ease, and patients are told to avoid strenuous exercise, heavy sweating and makeup for 24 to 48 hours.www.koreaclinicguide.com/blog/rejuran-healer-korea2026-10-31
Day 3 to 7Most visible swelling has resolved. Any bruising from the needles fades within a week, and normal skincare and light makeup can resume.www.dovepress.com/expert-perspectives-evidence-based-applications-of-polynucleotides-pns-peer-reviewed-fulltext-article-CCID2026-10-31
Day 7 to 14Clinics continue to recommend daily SPF 30 or higher and avoiding direct sun, sunbeds and saunas for up to two weeks, since the skin remains more reactive to UV after the injections.acibademinternational.com/blog/rejuran-and-polynucleotides-salmon-dna-injections-what-they-are-and-what-studies-show2026-10-31
Week 3 to 4A second or third session is scheduled 3 to 4 weeks after the first, since Rejuran is given as a course of 3 to 4 treatments, not a single visit.www.dovepress.com/expert-perspectives-evidence-based-applications-of-polynucleotides-pns-peer-reviewed-fulltext-article-CCID2026-10-31
Month 2 to 4Collagen and hydration effects described in clinical studies continue to build over this period, and maintenance sessions are repeated every 3 to 4 months to sustain results.pmc.ncbi.nlm.nih.gov/articles/PMC42480062026-10-31

Frequently asked questions

QuestionAnswer
How soon after Rejuran can I fly home from Seoul?Clinics say travellers can fly once facial swelling and redness have visibly gone down, which is 24 to 48 hours after the injections for most people, though those with more bruising sometimes wait up to a week.
Will there be visible bumps or bruising on my flight?Each session leaves 40 to 60 small raised bumps at the injection points that flatten within 12 to 36 hours for most patients, and any bruising fades within about a week.
Can I wear makeup before or during the flight home?Most clinics ask patients to skip makeup on the day of treatment and say light makeup is fine from the next day once the skin has settled.
How many Rejuran sessions will I need, and does that change my trip length?Rejuran is given as a course of 3 to 4 sessions spaced 3 to 4 weeks apart, so travellers who want the full course either plan several short trips or book one session and return later for follow-ups.
Is Rejuran a regulated medicine or a cosmetic product?Rejuran is registered as a polynucleotide-based medical device, not a drug. Outside Korea, regulators such as Australia's Therapeutic Goods Administration list Rejuran-brand fillers as Class III devices, and it has not been cleared by the US FDA for injectable aesthetic use.
Can I exercise, drink alcohol or use a sauna before my flight?Clinics advise avoiding strenuous exercise and heavy sweating for 24 to 48 hours, and skipping alcohol, smoking, saunas and swimming pools for about a week after treatment.
