How many GOURI sessions, and how far apart
Collagen boosters are often presented as “three sessions as standard”. We make one session the baseline, because a spreading formulation can cover the whole face as a sheet in one go — and then we see you again at four weeks to decide whether more is needed.
The short answer
We start with one session. Then we see you again at four weeks, look at the skin, and decide whether to add. Further sessions go at four-to-six-week intervals, and the result is judged at twelve weeks. We do not fix the number in advance for one reason — skin comes up at different rates in different people.
Why not “three sessions required”
Collagen boosters are often presented as “three sessions as standard”. We do not set GOURI up that way, because a spreading formulation can cover the whole face as a sheet in one go.
Particle-carrying products fill points, so building up over several sessions is a natural design. With GOURI, one full-face divided placement already covers the sheet. It therefore makes more sense to place once, see the result at four weeks, and decide whether more is needed.
There is a practical reason too. Polycaprolactone has no reversal injection. Too little can be topped up; the other direction is harder. So we start conservatively.
Our session standard
| Session 1 | The baseline — deep dermis, divided across the full face, conservative volume |
|---|---|
| Four weeks | We see you again — has the light come up, and is more needed |
| Further sessions | Four-to-six-week intervals — only for those who need them |
| Twelve weeks | The result is judged against the before photo |
| After that | Decided on the state of the skin, not on a calendar |
If the skin has come up well at four weeks, we do not recommend adding. The goal is the skin, not completing a course.
Why the interval is four to six weeks
It follows from the mechanism. GOURI signals your own collagen to form, and that change starts to show from four weeks.
- Adding sooner than four weeks means judging before the first placement has come up — which can mean an unnecessary session.
- Adding at four to six weeks lets us see how far the first placement got and top up only where it is short.
- It can differ by area. Cheeks sufficient but the forehead wanting more is a real and common pattern.
The full course over time is in GOURI — from the day of the injection to months later.
When to come back after that
After the twelve-week review, the next step is decided on the state of the skin rather than a date. When texture starts to feel coarser again is the point to reassess.
At that point GOURI may be right again — or something else may suit better in between. If laxity has increased, a device comes first; if hydration is the goal, an HA booster gets there faster. The comparison is in GOURI, Rejuran, Re2O and Juvelook compared.
Ordering it with other treatments
Combining is fine. We just stagger them.
- Not on the same day. If a reaction occurs, it has to be attributable to one or the other.
- One first, review at four weeks, then settle the combination.
- Vaccination, dental work or a cold close by — we leave about two weeks either side.
Frequently asked questions
How many GOURI sessions will I need?
We start with one session and see you again at four weeks to decide about adding, at four-to-six-week intervals if we do. If the skin has come up well at four weeks, we do not recommend more.
Do I have to complete three sessions for it to work?
No. GOURI spreads, so one placement can cover the whole face as a sheet. It is not designed to be built up over sessions the way point-filling products are. Place once, see the result at four weeks, then decide.
Can the interval be shortened to three weeks?
We would not. The change starts to show from four weeks, so adding earlier means judging before the first placement has come up — which can mean an unnecessary session. We work to four to six weeks.
Is a single session worth having?
Yes — it is why we make one session the baseline. Divided across the full face, one placement already covers the sheet, and the light comes up from four weeks. Anything more is decided from that result.
Does a second session add to the first?
It tops up where it is short. At four weeks it is common for the cheeks to be sufficient while the forehead wants more, and then we place only there. Repeating the whole face is not the default.
When is the next round after that?
Decided on the skin, not on a date. When texture starts to feel coarser again is the point to reassess. GOURI may be right again, or something else may suit better — we look at both.
Can I have other treatments between sessions?
Yes, but staggered. On the same day there is no way to tell which produced which response. We also leave about two weeks either side of vaccination, dental work or a cold.
