is this for me
Who it’s for
Even if none of these describes you, we will look again at the consultation.
- Dry or dehydrated skin that needs hydration as well as repair
- Those who want an immediate plumping effect alongside skin quality
- People who prefer a more comfortable injection (lidocaine in the formula)

Whether HB or another Rejuran formula suits you is confirmed during consultation.
start with your concern
Before you pick a treatment name, start with the cause of your concern.
Even a treatment with the same name takes on a different role and scope depending on your current structure, the change you want, what you have had before and the recovery time you have.
Where you are now, and where we start
Moisture and texture in dry, sensitive skin
The change you want, the impression you keep
Whether HB or another Rejuran formula suits you is confirmed during consultation.
How it differs from similar options
These injectable boosters all support skin quality, but they add different things — so the right one depends on whether you want hydration, repair or collagen support.
Health information and recovery schedule
Little downtime; small raised bumps at the injection sites may appear and usually settle within about 1–2 days. Temporary redness, mild swelling, tenderness or minor bruising may occur. Avoid makeup, saunas and intense exercise briefly, use sun protection, and follow the guidance we provide.
the principle
How it works
Before the product name we match the actual ingredients, the injection layer and your skin concern, then decide the dose, the interval and anything done alongside it.
Rejuran HB combines polynucleotides (PN) from salmon DNA with hyaluronic acid (HA), and its formula includes lidocaine. The PN supports the skin’s own repair, while the added HA provides immediate hydration and a plumping effect, and the lidocaine helps make the injections more comfortable. This blend is why HB is a frequent choice for dry or dehydrated skin and for those who prefer a gentler experience. “HB” refers to this hyaluronic-acid–blended formula.
How it works
Polynucleotides plus hyaluronic acid
HB blends polynucleotides (PN) from salmon DNA with hyaluronic acid (HA), and its formula also includes lidocaine.
Repair and immediate hydration
The PN supports the skin’s own repair, while the added HA provides immediate hydration and a plumping effect.
A more comfortable injection
The lidocaine in the formula is intended to make the microinjections more comfortable, alongside the numbing cream applied first.
Hydration early, quality over time
Hydration can be felt relatively early, while skin-quality change develops over a series of sessions. (Results vary by individual.)
the qd standard
The same treatment, never the same plan.
Rather than a fashionable name or a fixed package, we weigh the structure found at examination, safety, recovery and the limits within one plan.
- DIAGNOSIS FIRST
Cause before name
We first separate out the tissue and the function behind your concern.
- LESS, PRECISE
Only as much as needed
Rather than an excessive change, we plan the smallest scope with a clear role.
- HONEST LIMIT
The limits, explained too
We explain the change you can expect, the alternatives, individual differences and the risks.

what to expect
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0
Treatment day
Numbing first, then microinjections. Small raised bumps at the injection sites are common, with mild redness or swelling; skin may feel hydrated.
DAY 1-2
Bumps settling
The small bumps usually settle within about 1–2 days. Minor bruising, if any, starts to fade.
WEEK 1
Hydration felt
Many people notice a hydrated, plumped feeling relatively early from the hyaluronic acid. This varies between people.
1-3 MONTHS
Skin-quality change
Over the course and the following weeks, texture and elasticity may improve as the skin repairs. (Results vary by individual.)
AFTER THE COURSE
Review & maintenance
Your doctor reviews the outcome and discusses maintenance timing based on your skin.
Sessions & results
A typical plan is about 3–4 sessions spaced roughly 2–4 weeks apart, with hydration felt early and skin quality developing gradually over the following weeks. Maintenance is considered after a period decided at consultation. (Results vary by individual.)

before consultation
Before you decide, the questions people always ask
It is the same PN base with hyaluronic acid added. The hyaluronic acid brings moisture in straight away, and the PN then goes on supporting the skin's own recovery. That is why most people notice the hydrated, plumper feeling sooner after the session. It tends to be chosen by those who are troubled by dryness as well.
The formula contains an anaesthetic, so patients tell us the injection itself hurts less. The sensation of the needle going in still remains, though, so we use numbing cream alongside it. If you have ever reacted to a local anaesthetic such as lidocaine, you must let us know beforehand.
Hyaluronic acid draws water in, so the face can look fuller straight after the session. Combined with the swelling that follows any injection, looking puffier than usual for a day or two is normal. It usually settles on its own, but if only one side is severe or the swelling keeps growing, it needs to be checked.
If dryness is your main concern you can carry on with it, but what your skin needs may change over time. Once firmness or scarring becomes the bigger concern, a different formula suits you better. At the end of every course we look again at what troubles you most right now, and decide from there.
It is not a treatment that is tied to a season. Dryness gets worse in winter, but strong air conditioning does the same in summer, so we decide by looking at the condition of your skin. Sun care afterwards is needed whatever the season, though, so we recommend keeping sunscreen with you.
Start by comparing the make-up of each product with your own skin concerns and the area to be treated. Rejuran HB adds hyaluronic acid (HA) and lidocaine to polynucleotide (PN), so it is mainly considered for dry skin that lacks moisture, while Healer works on the overall texture of the face with PN and no hyaluronic acid. Please also tell us at the consultation how you would like pain to be managed and how you reacted to injectable treatments in the past.
Look at the examination and the plan rather than the treatment name. First, what the clinic checks before deciding — at QD Clinic in Gangnam, Seoul, the first thing we look at for this treatment is “Moisture and texture in dry, sensitive skin”. Second, whether it explains why it recommends that scope and method, compared with the alternatives. Third, whether it reviews your progress with you when results are expected. Our doctor goes through these three points at consultation before the treatment is decided.
