Skin booster sessions and intervals: it depends on product
Question: How many skin booster sessions do I need, and how far apart?
Short answer
Skin boosters are usually given as a series of repeat sessions rather than once, and the number of sessions and intervals differ by product. The Juvelook manufacturer usually recommends 3 sessions about 6 weeks apart (about 8 weeks for Juvelook Volume), while for PN there is a study of 4 sessions at 2-week intervals and a European consensus suggesting 3 sessions at 3-week intervals. Results and how long they last vary between individuals, so the plan is decided at consultation based on your skin condition and when you can visit.
Key points
- Sessions and intervals differ by product and ingredient
- Juvelook: maker says usually 3 sessions, about 6 weeks apart
- Juvelook Volume: maker states about 8 weeks apart
- PN: 4 sessions 2 weeks apart (study); 3 at 3 weeks (EU)
- If repeat visits are hard, the plan fits your schedule
How many skin booster sessions are usually needed?
Depending on the product, repeat treatments such as 3 or 4 sessions are suggested, and the exact number depends on the product and your skin condition.
The Juvelook manufacturer usually recommends 3 sessions, and for PN there is a study of 4 injections at 2-week intervals and a European consensus suggesting 3 sessions at 3-week intervals. These figures come from product-specific data and are not applied directly to other products.
An official recommended interval from the manufacturer of Rejuran could not be confirmed, so the number of sessions and interval for Rejuran are decided by the medical team at consultation based on your skin condition.
| Product/type | Sessions | Interval | Basis |
|---|---|---|---|
| Juvelook | Usually 3 | About 6 weeks | Manufacturer FAQ |
| Juvelook Volume | Usually 3 | About 8 weeks | Manufacturer FAQ |
| PN (study) | 4 | 2 weeks | Study cited in the Rho 2024 review |
| PN (European consensus) | 3 | 3 weeks | Results suggested to usually last 6-12 months |
| Rejuran manufacturer recommendation | Not confirmed | Not confirmed | Decided at consultation |
How far apart are the sessions?
Intervals also differ by product: about 6 weeks for Juvelook, about 8 weeks for Juvelook Volume, and for PN, 2 weeks in a study and 3 weeks in a European consensus.
The Juvelook manufacturer explains that the number of sessions and intervals may vary with the area, the response and the medical team's judgment. The PN intervals come from a study (2 weeks) and a European consensus (3 weeks) and vary by product and individual.
If bumps or bruises from the previous session are still present, the timing of the next session may be adjusted, so it is helpful to tell us how you are recovering before your next visit.
How long do the results last?
How long results last varies by product and individual; for PN, a European consensus suggested that results usually last 6-12 months after 3 sessions.
A randomized study (159 people) of repeated injections of an HA and glycerol product reported increased skin hydration for up to 16 weeks. The Juvelook manufacturer explains that maintenance treatments may be recommended afterward.
These periods are based on studies and manufacturer data, and not everyone gets the same results. Reactions such as redness, swelling, bumps and bruising can also occur with each session.
What if I cannot visit many times, for example as an overseas visitor?
CELITA Clinic designs treatment protocols with the situation of overseas visitors, who find repeat visits difficult, in mind.
If you share the length of your stay, your departure date and when you might be able to visit again during consultation, the products and schedule are reviewed accordingly. CELITA Clinic recommends having treatments that may cause bruising or swelling on the last day of your trip.
If you have an important event such as a wedding, the clinic advises having a skin booster 1 month before and only soothing care in the final week.
FAQ
Is one session enough?
A single session is possible, but most manufacturer and research data are based on repeat treatments. What you can expect from one session depends on the product and your skin condition, so it is a good idea to discuss this at consultation.
If I miss the interval, do I have to start over?
Official data do not provide a standard for this. If you tell us the date and product of your previous session, the medical team will decide the next plan based on your current condition.
Can I plan lifting and skin booster cycles together?
The combination and order of treatments differ for each procedure, so the plan is reviewed during consultation. Telling us all the treatments you are having and their cycles helps schedule them so they do not overlap.
