Skin boosters are less a one-off treatment than a standing appointment with your skin.
How long do skin boosters last? Most skin booster results last around six months after the initial course, with some products and protocols lasting up to a year; maintenance is typically a single session every six to twelve months, depending on the product and your skin.
The typical range
Around six months
After the initial course, most skin booster results last roughly six months before skin quality gradually returns toward baseline.
Some last longer
Certain products and protocols extend to nine or twelve months, particularly polynucleotide treatments where the effect builds over a longer timeframe.
Longevity by product type
| Product type | Initial course | Maintenance* |
|---|---|---|
| Profhilo (HA bio-remodelling) | 2 sessions, 4 weeks apart | Every 6–9 months |
| Restylane-type skin boosters | 3 sessions, 2–4 weeks apart | Every 6–12 months |
| Polynucleotides | 2–3 sessions, 3–4 weeks apart | Every 9–12 months |
*Typical protocols; your plan is confirmed at consultation.
Why the course matters
Longevity starts with completion
Skipping sessions in the initial course usually shortens how long results last, because the full stimulus was never delivered.
Peak then plateau
Peak results typically appear around four to eight weeks after the final session, then hold before gradually fading.
What makes results fade faster
Longevity is shortened by:
- Strong, regular sun exposure
- Smoking
- Dehydration and poor sleep
- A very dry or air-conditioned environment
- Skipping maintenance for long periods
- Naturally faster metabolism
In a tropical climate
Sun and air-conditioning
On Koh Samui, year-round UV and constant air-conditioning both dehydrate and age skin, which can shorten how long a booster result looks its best.
Sun protection extends results
Daily broad-spectrum sun protection is the most effective way to protect both your skin and your treatment.
When to book maintenance
Before it fully fades
Most people book maintenance as glow and firmness start to soften, rather than waiting until skin has returned to baseline — this keeps results more consistent.
Single-session top-ups
Maintenance is usually one session rather than repeating the whole course, which makes ongoing care simpler.
Do results improve with repeat treatment?
Often, yes
Because these treatments stimulate collagen and elastin, regular treatment over time can improve baseline skin quality, so each round starts from a better place.
Consistency beats intensity
Regular, spaced maintenance generally outperforms occasional intensive courses.
Making your results last
To get the most from skin boosters:
- Complete the full initial course as recommended.
- Allow 4–8 weeks after the final session before judging results.
- Use daily broad-spectrum sun protection.
- Stay hydrated and keep a consistent skincare routine.
- Book maintenance as glow starts to soften, not after it has gone.
- Discuss combining with other treatments if you want more.

Frequently asked questions
How long do skin boosters last?
Most results last around six months after the initial course, with some products lasting up to a year. Maintenance is typically a single session every six to twelve months.
How often should I have skin booster maintenance?
Usually every six to nine months for Profhilo-type treatments and every nine to twelve months for polynucleotides. Book as glow and firmness start to soften rather than after they have gone.
Do I need the full course for results to last?
Yes. Skipping sessions in the initial course usually shortens longevity, because the full stimulus was never delivered. Peak results appear four to eight weeks after the final session.
What makes skin booster results fade faster?
Strong sun exposure, smoking, dehydration, poor sleep, very dry or air-conditioned environments, and long gaps without maintenance can all shorten how long results last.
Do results get better with repeat treatments?
Often. Because these treatments stimulate collagen and elastin, regular treatment over time can improve baseline skin quality, so each round starts from a better place.
Is maintenance a full course again?
No, usually a single session rather than repeating the whole initial course, which makes ongoing maintenance simpler and less costly than starting over.
Safety and consultation
Skin booster injections is a medical procedure and, like any injectable, carries some risk — common temporary effects can include redness, swelling, bruising or a mild headache, and less common reactions are possible. Results vary from person to person, and no specific outcome can be promised. This article is general information, not medical advice.
At LIV Clinic, every treatment begins with an in-person assessment by Dr. Narathai Vichienkalayarut, M.D., who reviews your skin, medical history and goals before recommending a personalized plan. Book a consultation to find out whether this treatment suits you.
