Skin boosters improve hydration, glow and skin quality, but their results are not permanent. How long they last depends on the product, the number of sessions and your own skin. In general, most plans involve an initial course followed by regular top-ups. This guide explains how long results usually last, how many sessions each product needs and what makes results fade sooner. If you would like a doctor to plan your sessions, contact CLEO Clinic.
Why Skin Booster Results Are Temporary
Skin boosters are made from substances the body breaks down over time. For example, free hyaluronic acid is broken down by natural enzymes in the skin, while polynucleotides and collagen are gradually absorbed. As a result, the hydration effect fades unless the treatment is repeated. However, some boosters are designed to support the skin’s own repair, so part of the improvement may outlast the product itself. For an overview of the different types, see our skin booster treatment page.
When Results Start to Show
Results build gradually rather than appearing overnight. First, bumps and redness settle within a few days. Then, hydration and glow usually become noticeable over the following one to three weeks. Finally, changes in texture and skin quality build further over a course of sessions. If you are wondering what is normal in the first few days, read our guide to skin booster side effects and aftercare.
How Long Results Last by Product
The table below summarises what manufacturers or published studies say about each product. Where no reliable source exists, we say so, and your doctor will set the plan.
| Product | Type | Usual initial plan | How long results last |
|---|---|---|---|
| NCTF 135HA | Free hyaluronic acid with nutrients | Three sessions about three weeks apart | Maintenance at least twice a year, per the manufacturer |
| SKINVIVE | Lightly cross-linked hyaluronic acid | Often one treatment, with a touch-up if needed | Up to about six months, per the manufacturer |
| Profhilo | High and low molecular weight hyaluronic acid | Usually two sessions about a month apart | Varies; your doctor plans maintenance |
| Rejuran | Polynucleotides (salmon DNA) | A course of several sessions, a few weeks apart | Varies; your doctor plans maintenance |
| Linerase | Type I collagen | A course of several sessions, a few weeks apart | Varies; your doctor plans maintenance |
| JUVELook | Collagen stimulator | Doctor-planned course | Varies; changes build over months |
NCTF 135HA
According to FILLMED, NCTF 135HA is given as a course of three sessions about three weeks apart. After that, the manufacturer recommends at least two courses a year for maintenance. In a 2026 neck trial, results were followed for 24 weeks, but the authors noted this is too short to judge how long the effect lasts (Jiang et al., 2026). For full details, see our NCTF 135HA page.
SKINVIVE
Allergan Aesthetics states that SKINVIVE results last up to six months with optimal treatment. Because it uses lightly cross-linked hyaluronic acid, it is often given as a single treatment, with a touch-up if needed. To learn more, see our SKINVIVE by Juvéderm page.
Profhilo
Profhilo is usually given as two sessions about a month apart. In a small 2015 study in ePlasty, skin hydration and elasticity measurements improved at three months after this two-session course (Laurino et al., 2015). However, the study included only 11 women and had no control group, so it does not show how long results last. For more on timing, read our guide on when to schedule your next Profhilo treatment, or see our Profhilo treatment in KL page.
Rejuran and Other Polynucleotides
Usually, Rejuran is given as a course of several sessions, although the exact plan depends on the product type and your skin. Notably, a 2026 expert review concluded that much of the evidence for polynucleotides comes from small studies and clinical experience (Rho et al., 2026). For this reason, there is no reliable figure for how long results last. For a realistic timeline, read Rejuran before and after results, or see our Rejuran and PLINEST and NEWEST pages.
Linerase and JUVELook
Linerase and JUVELook are collagen-based or collagen-stimulating treatments rather than classic hydration boosters. Because they aim to support the skin’s own collagen, changes tend to build more slowly over weeks to months. Still, published data on how long their results last are limited, so your doctor will plan maintenance based on your response. To learn more, see our Linerase and JUVELook pages.
What Makes Skin Booster Results Fade Sooner
Several factors affect how long results last. For example, sun exposure, smoking, poor sleep and dehydration all speed up skin ageing. Similarly, people with a fast skin turnover or very dry skin may notice the effect fading sooner. In addition, skipping the initial course and having only one session usually gives a shorter-lived result. Therefore, daily sunscreen and a simple skincare routine help protect your investment, as our guide to physical vs chemical sunscreen explains.
How Often Should You Have Top-Ups?
Most people need an initial course, followed by maintenance sessions every few months. However, the right interval depends on the product, your age, your skin and your goals. In practice, your doctor will review your skin at follow-up and suggest a top-up when the effect begins to fade, rather than on a fixed calendar. If you have an event coming up, our guide to avoiding skin booster injections before events explains how to plan top-ups around it.
Skin Booster vs Filler: Which Lasts Longer?
In fact, fillers tend to last longer than skin boosters, because they use more heavily cross-linked hyaluronic acid designed to add volume. In contrast, boosters use free or lightly cross-linked products designed to hydrate the skin. For a full comparison, read our guide to skin boosters vs dermal fillers. Separately, our guide to how long fillers last in different areas explains filler timelines.
Can You Combine Boosters to Make Results Last Longer?
Some people combine boosters for different goals, for example hydration with one product and repair with another. However, combining products does not necessarily make results last longer, and spacing between sessions matters. For this reason, combinations should be planned by a doctor. To compare two popular options, read NCTF 135HA vs Profhilo.
Plan Your Skin Booster Course at CLEO Clinic
A consultation helps match the right booster and schedule to your skin. During the visit, the doctor examines your skin, explains how many sessions you are likely to need and gives you a plan and cost before you start. To get started, book a consultation with CLEO Clinic.
Frequently Asked Questions
How long does a skin booster last?
It depends on the product. For example, the manufacturer states that SKINVIVE lasts up to about six months, while NCTF 135HA is repeated at least twice a year. For other products, your doctor plans maintenance based on your response.
How many skin booster sessions do I need?
Most boosters need an initial course of two to three sessions a few weeks apart. However, SKINVIVE is often given as a single treatment.
Is one skin booster session enough?
For some products, such as SKINVIVE, one session may be enough. For most others, a course gives a better and longer-lasting result.
Do skin booster results disappear suddenly?
No. Results fade gradually as the product is broken down, so the skin slowly returns to how it was before treatment.
Is it bad to stop skin boosters?
No. If you stop, your skin gradually returns to its usual condition. It does not become worse than before because of the treatment.
