Tried to Finish Rejuran in Just 1 Session
Why It Can Actually Waste Your Money

Before reading today’s post,
answer just three questions.
Q. Does Rejuran
always require 3 sessions?
No. Depending on your skin condition,
even 1 session can be meaningful,
and for some people, 3 sessions are essential.
Q. Between 1 and 3 sessions,
is the difference big enough to feel?
Yes. For some, it’s like night and day,
while for others, it feels similar.
I’ll explain the criteria.
Q. Can I try just 1 session first
and then decide?
It’s possible, but if you start without a plan,
the treatment intervals get messed up and the effect is reduced by half.
1. Rejuran,
How Many Sessions Are Standard?

This is the question I hear most during consultations.
“Doctor, can I do just 1 session?”
The answer differs by case,
but if you understand the principle, the answer becomes clear.
Rejuran (PN) gives regenerative signals to the skin
and is a procedure that 'accumulates' collagen synthesis.
So usually, 3 sessions at 3–4 week intervals
are recommended as one set.
However, depending on your starting point (current skin condition),
the number of needed sessions varies.
2. 1 Session vs 3 Sessions,
The Real Difference You Feel

Depending on your starting skin condition,
the perceived change is completely different.
Category | After 1 session | After 3 sessions |
Hydration | Temporary improvement (2–4 weeks) | Longer-lasting due to cumulative effects |
Elasticity·Texture | Minimal change | Clearly noticeable from accumulated regeneration |
Fine lines | No major change | Gradually improves after completion |
Suitable case | Good skin condition, maintenance purpose | Loss of elasticity, anti-aging/regeneration purpose |
If your skin is already in good condition and your goal is maintenance,
occasional single sessions are appropriate.
But if your elasticity has dropped
or you strongly want texture improvement,
with just 1 session,
there’s a high chance you’ll think, “That’s it?”
👨⚕️ Director Wi Young-jin’s Practical Note:
Among first-time visitors,
about half are fine with just 1 session,
but the other half try to get more effect later
and add more sessions consecutively.
The problem is, if you start without a plan,
the intervals become too spread out.
If you get the second session
after the first effect has fully worn off,
you won’t properly get the cumulative (stacking) effect.
Even if you start with 1 session, if you may add later,
it’s better to plan in advance when to get the next one.
3. How Many Sessions Are Right for Me?
(Self-check)

✅ Cases where 1 session is fine
ㅇPeople with healthy skin aiming for seasonal care
ㅇPeople adding it as supportive care alongside other procedures
ㅇPeople already receiving it regularly and in the maintenance phase
✅ Cases where a 3-session set is recommended
ㅇPeople who clearly feel their skin elasticity has decreased
ㅇPeople mainly concerned about fine lines and rough skin texture
ㅇPeople getting Rejuran for the first time expecting regenerative effects
ㅇPeople who also want scar and pore improvement
⚠️ Caution: Irregular intervals
are a waste
The key to Rejuran is 3–4 week intervals.
If you’re busy and get the second session 2–3 months later,
the cumulative effect disappears
and you’re basically back to session one.
If being busy or forgetting might cause delays,
it’s better to set your booking intervals from the start—
that’s how you save both money and time.
💬 Frequently Asked Questions (FAQ)
Q1. If 1 session doesn’t work,
are 3 sessions also useless?
No. With Rejuran, rather than right after one session,
the real effect appears
when collagen has built up after completing 3 sessions.
Don’t judge too quickly.
Q2. Can I get all 3 sessions
within one month?
Not recommended.
Cells need time to regenerate.
Please keep at least a 3-week interval.
Q3. What about after finishing 3 sessions?
Usually, once every 3–6 months,
just 1 maintenance session is enough.
For Rejuran, the plan also differs depending on the type (Eye, Healer, Skin Booster).
