Hello.
I’m Beauty’s Doctor, Wi Young-jin.
When consulting on Rejuran HB,
there is a question that customers almost always ask.
“How long do Rejuran HB results last?”
Especially for those looking for clinics around Hongdae, Hapjeong, and Mapo,
many worry about the duration, asking,
“What if the effect disappears too quickly?”
However, in actual treatment, the duration of the effect
varies quite a bit from person to person.
This is because it can differ depending on three factors:
skin condition
lifestyle habits
procedure method
Today, I’ll organize the effects of Rejuran HB
and its duration.
What kind of procedure is Rejuran HB?

Rejuran HB is a skin booster procedure
that injects polynucleotide (PN),
derived from salmon,
into the dermis layer of the skin.
The PN ingredient
✔ improves damaged skin conditions
✔ activates fibroblasts
✔ induces collagen production
and helps restore the skin’s regenerative environment.
It also contains hyaluronic acid,
so you can additionally expect effects such as
✔ skin moisturization
✔ skin glow
✔ improved skin texture
So Rejuran HB is better understood not as a procedure that simply fills wrinkles,
but as one that enhances the skin’s own regenerative power.
When do Rejuran HB results appear?
Rejuran HB is not a procedure where you immediately notice changes right after treatment,
but rather one where effects appear gradually as the skin regeneration process progresses.
Usually,
✔ after 2–3 weeks: changes in skin texture
✔ after 1–2 months: noticeable improvement in elasticity
are commonly felt.
Although it varies by person,
after about a month, many people say,
“My skin seems better.”
Duration of Rejuran HB results

The duration of Rejuran HB results
is generally known to be about 8–12 months on average.
However, in actual clinical practice,
✔ it may last about 6 months, or
✔ it may be maintained for more than 12 months.
This difference can depend on factors such as
- degree of skin aging
- lifestyle habits
- procedure design
Cases where the effect lasts longer
In my clinical experience,
in the following cases, the effect tends to last relatively longer.
✔ Skin care purpose in the early to mid-30s
✔ Purpose of improving fine wrinkles
✔ Purpose of managing skin elasticity
In particular, when the skin has become dull
and the skin texture has become rough,
people who receive the procedure for the purpose of restoring the skin environment
often report high satisfaction.
Cases where the duration may be shorter
On the other hand, in the following cases,
the duration may be somewhat shorter.
✔ When skin aging has progressed significantly
✔ Smoking habits
✔ Lack of sleep
✔ Frequent exposure to ultraviolet rays
That is why, during consultation,
it is important to check
✔ skin condition
✔ lifestyle habits
✔ degree of skin aging
together.
How to maintain Rejuran HB results for longer

Post-procedure care can also affect how long the results last.
In particular, care during the first week after treatment is important.
✔ Avoid alcohol
✔ Avoid saunas / jjimjilbang
✔ Use sun protection
✔ Drink enough water
Just taking care of these basic points well
can help the skin recovery process.
After the procedure,
✔ swelling
✔ embossing
✔ small bruises
may appear,
but in most cases,
these naturally improve within 2–3 days.
However,
if swelling or inflammatory reactions
last for more than a week,
it is better to consult the clinic.
Frequently asked questions
Q. When do Rejuran HB results appear?
Usually, changes in skin texture are often felt starting after 2–3 weeks.
Improvement in elasticity is often noticed after about 1–2 months.
Q. How many sessions are needed?
For the purpose of skin improvement,
people often undergo about 2 sessions
at intervals of 2–3 months in the beginning.
After that,
many people receive maintenance care
1–2 times a year.
Q. Can it be done together with other procedures?
Yes.
✔ Botox / filler: usually at an interval of about 2 weeks
✔ Laser procedures: usually at an interval of about 1 week
However, the treatment plan may vary depending on the skin condition.
Rejuran HB is not simply a procedure that fills wrinkles,
but a skin booster procedure that improves the skin’s regenerative environment.
So the changes are natural,
and the duration of the effect is relatively long.
However,
✔ skin condition
✔ degree of skin aging
✔ lifestyle habits
can cause differences in results and duration.
Therefore, if you are considering the procedure,
after checking your current skin condition,
it is better to establish a care plan that suits your skin
through consultation with a specialist.
