Juvederm vs Rejuran
Juvéderm is for volume you can point at. It is a hyaluronic acid gel that fills a lip, a cheek or a fold on the day, lasts roughly a year, and can be dissolved if you change your mind. Rejuran is for the surface of the skin. It uses polynucleotides, fragments of salmon DNA, to improve texture and fine lines across three visits, and it adds no volume at all. They fix different complaints, so the choice is usually easy once you name yours.
What is in the syringe
Hyaluronic acid is a sugar your skin already makes. The gel holds a space open.
Purified DNA fragments. Not a filler, and no volume.
What it improves
Thin lips, flat cheeks, a weak chin, a deep fold beside the nose. It changes the outline of your face.
Rough texture, fine lines, shallow acne scars, large pores and skin that reacts to everything.
What it will not do
A filled cheek can still look dull and uneven on the surface.
A flat cheek stays flat. A thin lip stays thin.
When you see the result
Swelling settles over about two weeks and the look settles with it.
Nothing changes on the day. Texture improves first, then fine lines.
How many visits
A top-up later if you want more.
Spaced three to four weeks apart, then one session every six to twelve months.
How long it lasts
Longer in the cheek, shorter in the lips, because the lips move constantly.
It is a maintenance treatment. Skin drifts back if you stop.
Can it be undone
Hyaluronidase dissolves it, usually within a day or two.
There is no material left sitting there, so there is nothing to dissolve. It simply wears off.
What it feels like
Most Juvéderm products contain a numbing agent already.
Spread across the whole area, so it takes longer and is the less comfortable of the two. Small bumps flatten within a day or two.
Side effects to expect
Lumps and unevenness happen, and they can be dissolved.
Marks at each injection point for a day or two. Plan a few clear days.
Cost
Easy to total up front. Repeat visits add up over the years.
Ask for the cost of the full course rather than one visit.
The at-home or drugstore version
A serum holds water in the top layer for a few hours. Filler goes millimetres down.
Topical products with these ingredients exist and feel pleasant. Injected polynucleotides are placed inside the skin, which a cream cannot do.
Who each suits
They are not really competitors
Juvéderm changes the shape of your face: It is placed where volume is missing and holds that space. Someone looking at you sees a fuller cheek or a fuller lip.
Rejuran changes the surface of your skin: It is spread through the skin itself, a few millimetres down, and the aim is a smoother, less fragile surface. Nobody sees a change in shape.
Plenty of people have both, at separate visits: One for structure and one for skin quality is a common plan, and they do not overlap.
Reversibility is worth understanding here
Juvéderm can be taken back out: If it looks wrong or moves, hyaluronidase dissolves it in a day or two. That is the strongest argument for it as a first injectable.
Rejuran has nothing to take out: No gel is left sitting in the tissue, so a result you dislike simply fades. That is not the same as being reversible, but it does mean there is no lump to remove.
Neither one traps you: Between them, this pair is about as low-commitment as injectables get.
Where these are used
Rejuran is not approved in the United States for these uses: It is widely used in Korea and in several other countries. Some US clinics offer it anyway. It is fair to ask a clinic what they use and where it comes from.
What neither one does
Neither one softens a frown line or crow's feet: Those come from muscle movement, and botulinum toxin is the treatment that works on muscle.
Neither one tightens loose skin: Filler adds volume and Rejuran improves the surface. If sagging is your main complaint, energy devices or surgery are the honest answer.
Has anyone compared them directly
No trial has put Juvéderm against Rejuran: They are measured on different things, so a fair comparison would struggle to pick a single yardstick. Any claim that one beats the other comes from clinic experience.
Before you book
Describe the problem rather than naming a product. A hollow points one way, rough skin points the other.
Ask for the total cost, including every session in a Rejuran course.
Ask how many injection points to expect, so the bumps afterwards are not a surprise.
Leave a clear week before anything social. Both can bruise.
If a clinic suggests both, ask which to do first and why.
