Rejuran — how many cc does a whole face need?
It is the number people search for most before a consultation. “Is 2cc enough?”, “Is 4cc a lot?” The short version first: cc is not a target you set at the start. It is what falls out once the area, the product and the session plan are decided. Reverse that order and comparisons stop lining up. There are no prices in this column.
The short answer
The right dose of Rejuran is not settled first as “so many cc for the whole face”. Decide which areas are being treated, which product is being used and how many sessions the course runs to, and the volume per session follows from that. The figure people quote as “the standard” is not a recommended dose; it is closer to a phrase that hardened around the size of one vial. More is not better either — there is a limit to what skin takes in at one sitting, and past it you mostly get marks that last longer. At Miso Clinic the order is area → product → sessions → volume per session, and we tell you the reasoning as we go. Miso Clinic is at 4F Bombom Building, 125 Dongdeok-ro, Jung-gu, Daegu, in front of Exit 1 of Kyungpook National University Hospital Station. +82-53-428-2700, weekdays 11:00–19:00 · Saturday 10:00–16:00 (no lunch break), closed Sundays and public holidays.
Where did “2cc as standard” come from?
Rejuran is packaged by the vial, and once one is opened the rule is that it is used that day. It is not something to keep for next time, so the amount used at one sitting naturally becomes “one unit”. That is how one vial came to stand in for a default.
The misunderstanding starts there. That figure does not mean “this is what a face needs”; it means “this is the unit the product comes in”. Volume and intended use differ by product; Rejuran HB — how it differs from Healer covers one of those differences.
So “is 2cc enough?” cannot be answered as asked. Without knowing whether it is the cheeks only or the whole face, and whether the eye area is included, there is no way to say whether it is a lot or a little.
What decides the dose?
| What decides it | How it affects the volume |
|---|---|
| How much area is treated | Cheeks alone and forehead, cheeks and jawline together need different amounts. The wider the area, the more it takes |
| Which product | Products intended for the eye area come in a smaller unit. They should not be counted on the same scale as full-face products |
| The state of the skin | Dehydration with fine lines, or rough texture and open pores, change the spacing between injection points and so the volume |
| The session plan | How the total is divided sets the volume per session. Sessions are covered in Rejuran sessions — why a course of three |
Only once those four are settled does a cc figure appear. Fix the cc first and you end up stretching the area or widening the spacing to match it, which leaves some places dense and others empty.
Does more product give a better result?
No. There is a limit to how much skin takes in at one sitting. Past it, instead of a better result you get this.
- Injection bumps form more prominently and last longer — see the column on embossing
- More bruising and swelling, so a longer wait before going back to normal
- Where it gathers at one point, it can stay palpable for several days or more
Rejuran suits being divided across sessions with intervals better than being loaded in at once, because the skin takes time to respond. That is also why a course runs to several sessions.
“Let us do 4cc today” is not always better than “let us do 2cc twice and see”. The same total can give a different result.
Lining up quotes for comparison
If you have heard different numbers at different clinics, it is usually because they are counting different things. Put these on the same footing first.
- Product name — Healer, HB, HB PLUS or I. Different names, no comparison
- Area — whole face or cheeks only, eye area included or charged separately
- Sessions — one session or a course
- Anaesthesia and aftercare — included or separate. Sedation changes it again
The questions to take into that conversation are in Rejuran in Daegu — the consultation checklist. This column covers how the dose is arrived at; that one covers what to ask before you agree to it.
How Miso Clinic decides
- The area comes first. We look at where the concern actually comes from and narrow the field. Wider is not automatically better
- Then the product. The eye area gets the product made for it; where pain is a concern we look at the one containing anaesthetic
- Then the sessions, and the total is divided. We do not load it into one sitting
- The cc figure is what we then tell you. We do not put a number up front and work backwards to it
- If we judge it unsuitable, we do not recommend it. If hollowing is the main concern, that is a different conversation from boosters
In summary — what is established and what is not
Established
- Rejuran is supplied by the vial, and an opened vial is used the same day
- Unit volume and intended area differ across the product range
- Dividing treatment across several sessions is the usual design
Not established
- An official standard setting optimal injection volume by facial area
- A study comparing the same total given in one session against divided across several
- Korean clinical data measuring the dose-response relationship step by step
Rejuran dose — frequently asked questions
How many cc of Rejuran does a whole face need?
It is not a number that is settled first. Decide which areas are treated, which product is used and how many sessions the course runs to, and the volume per session follows. Without knowing the area, there is no way to say whether a figure is a lot or a little.
Is 2cc the standard dose for Rejuran?
That figure is not a recommended dose; it is closer to a phrase that hardened around the size of one vial. An opened vial is used the same day, so the amount used at one sitting naturally became one unit. Unit volumes differ by product.
Is more Rejuran better?
No. There is a limit to what skin takes in at one sitting, and past it injection bumps form more prominently and last longer, with more bruising and swelling. Dividing the total across sessions with intervals suits the product better.
Is 4cc in one session the same as 2cc twice?
The same total can give a different result. The skin takes time to respond, which is why dividing across sessions suits the design and why a course runs to several sessions.
Is the eye area counted in the same cc?
No. Products intended for the eye area come in a smaller unit and should not be counted on the same scale as full-face products. When comparing quotes, always check whether the eye area is included or charged separately.
Why do clinics quote different cc figures?
Usually because they are counting different things. Product name, the extent of the area, whether the figure is per session or per course, and whether anaesthesia and aftercare are included all have to be lined up before a comparison means anything.
How many Rejuran sessions do I need?
Because the skin takes time to respond, the usual design divides treatment across several sessions with intervals. How the sessions are set depends on the state of the skin and the area, and is decided at consultation.

References
- Unit packaging and single-use — Rejuran is supplied in single-use syringes (vials); an opened product is used on the day and the remainder is not stored for reuse. Figures circulating as a “standard dose” derive from the packaging unit rather than from a recommended injection volume.
- Differences across the product range — The Rejuran range differs in intended area and packaged volume, and products intended for the eye area use a different unit volume from full-face products. Product detail is set out in the Miso Clinic Rejuran product reference.
- Divided treatment design — Skin boosters are usually designed as several sessions at intervals. We have not found a study comparing the same total volume given in a single session against divided across sessions.
- Injection marks and overfilling — Excess volume at a single point produces more prominent injection marks and slower recovery, and palpability lasting several days or more has been reported. We have not found an official standard setting optimal injection volume by facial area.
- Korean medical advertising law — Medical Service Act Article 56(2) prohibits testimonial advertising, comparison with other medical institutions and superlative claims.
