How Long Does Rejuran Take to Heal?

Rejuran is a popular skin booster treatment in Korea that uses polynucleotides (PN) to repair damaged skin, improve elasticity, and enhance overall skin quality. It is widely used in clinics across Myeongdong and Gangnam for acne scars, fine lines, and skin texture improvement. While downtime is minimal, the healing process follows a predictable timeline.

Immediately After Treatment (Day 0–1)

Right after Rejuran injections, it is normal to experience visible skin reactions.

• Small raised bumps at injection sites (papules)
• Mild redness and swelling
• Slight sensitivity or tightness
• Possible pinpoint bruising

These effects are expected and usually begin to calm within 24 hours.

Early Healing Phase (Day 2–3)

During the first few days, the skin starts to settle.

• Bumps gradually flatten
• Redness begins to fade
• Bruising may still be visible in some areas
• Skin may feel slightly dry or tight

Most people can resume normal activities during this stage.

Recovery Phase (Day 3–7)

This is when noticeable improvement in skin comfort begins.

• Injection marks fully disappear
• Skin texture becomes smoother
• Hydration levels gradually improve
• Sensitivity decreases

Makeup can usually be applied comfortably again.

Full Recovery (1–2 Weeks)

By this stage, the skin has largely healed externally.

• No visible injection marks
• Skin barrier is stabilized
• Improved glow and hydration become noticeable
• Subtle texture refinement begins

However, deeper regenerative effects are still developing.

When Do Results Fully Appear?

Rejuran works by stimulating long-term skin repair, so results improve gradually.

• Initial glow: within 1–2 weeks
• Noticeable improvement: 3–4 weeks
• Full effect: 4–8 weeks after treatment

For best results, multiple sessions are often recommended.

Factors That Affect Healing Time

Healing speed can vary depending on:

• Skin sensitivity and condition
• Injection depth and technique
• Number of injection points
• Post-treatment care routine
• Lifestyle factors (sun exposure, alcohol, etc.)

Proper aftercare can significantly improve recovery comfort.

Tips for Faster Recovery

• Apply soothing and hydrating skincare products
• Avoid alcohol and heavy exercise for 24–48 hours
• Do not rub or massage treated areas
• Use sunscreen daily
• Stay well hydrated

Gentle care helps reduce inflammation and speed up healing.

Final Thoughts

Rejuran typically heals within 3 to 7 days on the surface, with full skin recovery and visible improvement developing over several weeks. While initial bumps and redness are temporary, the long-term benefits—such as improved texture, elasticity, and hydration—continue to develop over time, making it a popular skin regeneration treatment in Korea.
