01Smoother texture or a change in contour — and how long is your stay?
Separate uneven texture and fine lines from deep hollows or sagging. The evidence compared here helps explain skin-texture changes; it does not establish correction of deep acne scars or a lifting result.
For fine lines and texture, changes were reported with a protocol combining Juvelook and additional HA. The cited Rejuran trial focused on hydration and texture around the eyes.
Read the comparison by concern and area, rather than assuming that the skin-booster label answers both.
If you are visiting Bangkok, set the studied timing against your dates. The Juvelook protocol spaced visits 4 weeks apart and the Rejuran trial 2 weeks apart, so a stay shorter than that allows one visit of either.
These studies do not establish what a single visit achieves. Before booking, ask whether the plan is one visit, a return trip or a longer stay, and what follow-up is possible after you fly home.
Skin concerns covered by the evidence here
How many visits were involved?*
When were outcomes assessed?*
What recovery effects were reported?
*Visits and follow-up dates come from research, not clinic packages or promised onset. Neither study directly compared Juvelook with Rejuran. Individual results vary.
02How do their formulas differ?
Juvelook combines PDLLA and HA; base Rejuran lists PN. They are different formulas even when both are described as skin boosters.
Juvelook and Rejuran HB plus both list an HA component, but the rest of their formulas differ. That shared component does not establish that they can be substituted, produce the same result or suit the same treatment area.
03How do Juvelook Volume and Rejuran HB plus differ from the base variants?
The manufacturer lists Juvelook at 50 mg and Volume at 200 mg. These figures describe ingredient mass, not injection volume, and do not establish a proportional increase in results.
Rejuran HB plus includes sodium hyaluronate and lidocaine hydrochloride alongside sodium polynucleotide. The manufacturer lists 1 mL per syringe, so keep this variant separate when comparing ingredients and quantities.
04Can a price per cc be compared directly with a price per box?
Not without the contents and treatment quantity. A cc price describes volume; a vial or box price needs its contents and the amount supplied per visit.
A smaller headline price does not establish a lower total treatment cost.
Compare the exact variant, amount per visit, number of visits and included fees before comparing plan totals. Do not divide Juvelook milligrams by Rejuran cubic centimetres: they measure different things.
If only one visit fits your trip, compare the amount supplied at that visit rather than a multi-visit course total, and confirm in writing what the quoted price includes.
05About the comparison evidence
The Juvelook evidence comes from 16 Korean participants treated with additional HA and lidocaine, without a control group. The Rejuran study treated 27 women around the eyes, comparing PN with HA on opposite sides of the face, not with Juvelook.
Both studies received manufacturer funding. They describe observations within their respective protocols, not a ranking of results, a fixed recovery deadline or same-day use of Juvelook and Rejuran.

06Common questions
Are Juvelook and Rejuran the same ingredient?+
No. Juvelook 50 mg lists PDLLA with HA, while base Rejuran lists PN. Separate the formulas first; the skin-booster label does not establish interchangeability.
Are all Rejuran variants identical?+
No. HB plus, for example, lists sodium hyaluronate and lidocaine hydrochloride alongside sodium polynucleotide. Base-formula descriptions should not be applied to every variant.
I am in Bangkok for one week. Can I complete either program?+
Not as the studies ran them. The Juvelook protocol used 2–3 sessions 4 weeks apart and the Rejuran trial 3 sessions 2 weeks apart, so one week fits only the first visit of either.
Neither study established the result of a single session. Share your dates before booking so the plan states what one visit includes and whether a return visit is proposed.
How do I compare a cc price with a vial price?+
First match the variant, amount supplied per visit, number of visits and included charges. Vials, boxes and cc cannot be treated as equivalent units without their packaging details.
Can I fly home soon after the treatment?+
The studies cited here do not set a flying interval for these injections. The CDC cites a 7–10 day wait before flying for some laser or cosmetic procedures to the face, eyelids or nose; that is a category-level caution, not clearance for any one treatment.
Tell the treating clinician your flight date before booking, and leave with written aftercare, a record of the product used and a contact route for follow-up at home.
Can Juvelook and Rejuran be performed together?+
These two studies do not answer same-day use of this pair. The Juvelook protocol added HA, not Rejuran; the Rejuran trial used HA on the opposite side, not combined with Juvelook.
Neither establishes same-day compatibility or a required interval for this combination.
