If you’re considering Rejuran, one of the most common questions is: rejuran how long does it last? The answer isn’t one-size-fits-all—but generally, results can last 6 to 12 months, depending on your skin condition, treatment plan, and lifestyle.
Unlike typical fillers, Rejuran works by repairing your skin at a cellular level using polynucleotide (PN), which means results improve gradually and last longer with proper maintenance.
What Is Rejuran and How Does It Work?
Rejuran is a regenerative injectable treatment derived from salmon DNA fragments (PN). It focuses on healing damaged skin, rather than simply adding volume like hyaluronic acid fillers.
Key Benefits:
- Improves skin texture and elasticity
- Reduces fine lines and wrinkles
- Enhances hydration and glow
- Strengthens skin barrier
The treatment stimulates collagen production and tissue repair, which explains why results develop over time rather than instantly.
How Long Does Rejuran Last After Treatment?
Average Duration of Results
Most patients can expect:
- Initial visible improvements: 2–4 weeks
- Peak results: Around 2–3 months
- Longevity: 6–12 months
The longevity depends on how well your skin responds to Rejuran Healer or other variants like Rejuran I.
Why Rejuran Lasts Longer Than Many Skin Treatments
Rejuran is often compared to skin boosters, but its mechanism is different.
Key Reasons:
- Works at the cellular repair level
- Stimulates natural collagen regeneration
- Improves overall skin health, not just appearance
This regenerative approach gives it longer-lasting benefits compared to treatments like skin boosters, which mainly provide hydration.
Factors That Affect How Long Rejuran Lasts
1. Your Age and Skin Condition
Younger patients or those with mild skin damage often see longer-lasting results.
2. Number of Sessions Completed
A full course (usually 3–4 sessions spaced 3–4 weeks apart) delivers better longevity than a single treatment.
3. Lifestyle Habits
- Smoking
- Sun exposure
- Poor skincare routine
These can shorten the duration of results.
4. Skincare Routine
Using medical-grade skincare and sunscreen helps extend Rejuran effects.
5. Treatment Area
- Under-eye (Rejuran I): May last slightly shorter
- Full face (Rejuran Healer): Typically longer-lasting
How Many Sessions Are Needed for Long-Lasting Results?
To maximize results:
Recommended Protocol:
- 3–4 initial sessions (every 3–4 weeks)
- Followed by maintenance every 6–12 months
This builds a strong foundation for collagen regeneration, ensuring longer-lasting improvement.
