Rejuran Healer injections are one of Korea’s most sought-after treatments for skin regeneration, anti-aging, and collagen boosting, thanks to their powerful polynucleotide (PN) formula derived from salmon DNA. But to ensure optimal healing and visible results, what you avoid after treatment is just as important as what you apply.
In this recovery guide, we break down everything you should avoid after Rejuran injections, based on protocols from leading Korean dermatology clinics.
🕒 Why the First 7 Days Are Critical
Although Rejuran is minimally invasive, it involves multiple microinjections into the dermis, creating controlled micro-wounds to trigger skin healing. During the first 3–7 days, your skin is in an active recovery state, and exposure to certain products, activities, and environments can compromise the healing process.
🛑 Top 10 Things to Avoid After Rejuran Healer Injections
1. ❌ Touching or Rubbing Your Face
Why: The micro-injection points are vulnerable to bacteria, irritation, and inflammation.
How Long to Avoid: 24–48 hours
What to Do Instead: Gently cleanse with clean hands and pat dry with a soft towel.
2. ❌ Wearing Makeup
Why: Foundations, concealers, and powders can clog injection sites and cause breakouts or infection.
How Long to Avoid: At least 24–48 hours post-injection
Tip: Use a mineral-based tinted sunscreen (if needed) once the skin is no longer broken or sensitive.
3. ❌ Using Active Ingredients (Retinol, AHA/BHA, Vitamin C)
Why: These can irritate the skin barrier and interfere with collagen production during the early healing phase.
How Long to Avoid: 7–10 days
What to Use Instead: Stick to hydrating and calming ingredients like hyaluronic acid, centella asiatica, or ceramides.
4. ❌ Exposing Skin to Direct Sunlight
Why: UV rays can damage newly treated skin and reduce the efficacy of Rejuran.
How Long to Avoid: Avoid sun exposure for at least 7 days, and apply broad-spectrum sunscreen daily thereafter.
What to Do Instead: Wear a wide-brimmed hat or avoid going out during peak UV hours (10 AM–4 PM).
5. ❌ Exercising or Sweating Excessively
Why: Sweating may cause bacteria to enter injection sites and provoke inflammation or bumps.
How Long to Avoid: 2–3 days
Tip: If you must move, opt for light walking in a cool environment.
6. ❌ Hot Showers, Saunas, and Steam Rooms
Why: Heat dilates blood vessels, which can increase swelling and reduce Rejuran’s effectiveness.
How Long to Avoid: At least 3–5 days
What to Do Instead: Take lukewarm showers and avoid face-steaming devices or baths.
7. ❌ Consuming Alcohol or Smoking
Why: Both reduce blood circulation and impair collagen regeneration and skin healing.
How Long to Avoid: At least 48–72 hours
Bonus: Avoid caffeine-heavy drinks if you’re prone to flushing or redness.
8. ❌ Getting Other Facial Treatments
Why: Combining Rejuran with treatments like lasers, microneedling, or peels too soon may over-stress the skin.
How Long to Avoid: Wait 2–4 weeks, unless your dermatologist advises a combination protocol.
What to Do Instead: Ask your clinic about calming LED or oxygen facials, which are safe post-injection.
9. ❌ Using Facial Massage Tools (Rollers, Gua Sha)
Why: These can spread injected material unevenly or worsen swelling.
How Long to Avoid: 1 week
What to Do Instead: Gently pat your products in with fingers, no pressure.
10. ❌ Sleeping Face Down
Why: Pressure can displace the product and irritate sensitive skin.
How Long to Avoid: First 2–3 nights
Tip: Sleep on your back with a clean pillowcase and consider elevating your head slightly to reduce swelling.
