Profhilo
Hyaluronic acid, and a lot of it A thin gel that spreads out under the skin instead of staying in one spot. Hyaluronic acid is a sugar your skin already makes, and it holds water.
Profhilo is better for skin that looks dry, dull or slightly loose. It is a hyaluronic acid gel that spreads under the skin to hydrate and mildly firm it, given as two visits a month apart. Rejuran is better for rough texture, fine lines, shallow acne scars and skin that is thin or easily irritated. It uses polynucleotides, which are fragments of salmon DNA, and runs as three visits. Both are courses rather than one appointment, and both are repeated once or twice a year.
| The difference | Profhilo | Rejuran |
|---|---|---|
| What is in the syringe | Hyaluronic acid, and a lot of it | Polynucleotides from salmon DNA |
| What it feels like | About ten quick stings | Many small pinpricks |
| Cost | Priced as a course of two | Priced per session, and you need three |

Profhilo
Hyaluronic acid, and a lot of it
A thin gel that spreads out under the skin instead of staying in one spot. Hyaluronic acid is a sugar your skin already makes, and it holds water.
Rejuran
Polynucleotides from salmon DNA
Purified DNA fragments. Not a filler, and no volume.
Profhilo
Hydration and mild firmness
Skin that looks dry and tired, and early looseness along the cheek and jaw. Also used on the neck, chest and hands.
Rejuran
Texture and repair
Fine lines, rough texture, shallow acne scars, large pores, and skin that reacts to everything.
Profhilo
Five set points on each side
Standard spots along the cheek, jaw and chin. The gel then spreads out from there.
Rejuran
Many small points across the area
Spread evenly through the skin, a few millimetres down.
Profhilo
One to two weeks for the glow
Skin often looks brighter early. The firmness needs both sessions and about four to six weeks.
Rejuran
Two to four weeks, building for three months
Nothing changes on the day. Texture comes first, then fine lines.
Profhilo
Two, four weeks apart
That pair is the course. Top-ups later are usually one visit.
Rejuran
Three, three to four weeks apart
Then one session every six to twelve months.

Rejuran
Six to twelve months
Profhilo
About ten quick stings
Small bumps like mosquito bites at each point. They flatten within a day or two.
Rejuran
Many small pinpricks
More injections than Profhilo, so it takes longer and is the less comfortable of the two.
Profhilo
It will not fix rough texture
Profhilo hydrates. Skin can look plumper while the surface still feels uneven.
Rejuran
It will not fill a hollow
Rejuran does not add volume. A flat cheek stays flat.
Profhilo
Priced as a course of two
Ask for the price of both sessions together.
Rejuran
Priced per session, and you need three
Three sessions usually costs more than a Profhilo course.
Profhilo
A serum is not a weaker version
A hyaluronic acid serum holds water in the top layer for a few hours. Profhilo is placed a few millimetres down, where collagen lives.
Rejuran
Salmon DNA serums are a different thing
PDRN creams and ampoules exist and feel pleasant. Injected polynucleotides are placed inside the skin, which a cream cannot do.
Profhilo
Rejuran
Profhilo
Profhilo is aimed at skin that has gone dry and slack. The gel holds water and spreads, so the whole area looks plumper and slightly firmer. The change is easiest to see on a cheek or a neck that has started to look thin.
Rejuran
Rejuran is aimed at the surface itself. It is chosen for skin that is rough, marked or reactive rather than skin that has lost tone. People often pick it for shallow acne scarring and enlarged pores.
