How long do anti-wrinkle injections last for first-time patients?

First-time patients often find their results last around 8–10 weeks as the body metabolises the product more quickly. From the second treatment onwards, results typically extend to 12–16 weeks.

Do anti-wrinkle injections last longer with higher doses?

Higher doses can extend duration slightly, but there is a ceiling effect. The more important factor is treating consistently over time. Your practitioner at ReGen Aesthetics Clinic will advise on the appropriate dose for your anatomy.

Can anti-wrinkle injections be topped up early?

Most practitioners recommend waiting at least 2 weeks before any top-up to allow the product to fully settle. Top-ups are assessed at a 2-week review appointment included with your treatment at ReGen Aesthetics Clinic.

How Long Do Anti-Wrinkle Injections Last? What to Expect in Merthyr Tydfil

How long do anti-wrinkle injections typically last?

For most clients, anti-wrinkle injections last between 10 and 16 weeks. The first treatment often metabolises faster — particularly if you haven't had the treatment before — with subsequent treatments generally lasting longer as the muscle learns to relax. By your second or third treatment, many clients find their results extend to 4–5 months.

What factors affect how long results last?

Metabolism plays the biggest role. Those with a faster metabolism — often people who exercise intensively or are very active — may find results fade more quickly. Muscle mass in the treated area also matters: stronger muscles require a higher dose and may metabolise the product faster. Sun exposure, smoking, and poor skin quality can also accelerate breakdown. Stress and illness can sometimes cause premature wearing off too.

Which areas last longest?

The forehead and frown lines (glabella) typically last longer than crow's feet, as the muscles around the eyes are more active throughout the day. Brow lifts and bunny lines tend to fall somewhere in between. At ReGen Aesthetics Clinic in Merthyr Tydfil, your practitioner will advise on the expected duration for each area treated during your consultation.

Can you make anti-wrinkle injections last longer?

Yes, to some extent. Maintaining a consistent treatment schedule (rather than letting results fully wear off between appointments) allows the muscle to progressively relax, extending longevity over time. Good skincare, sun protection, avoiding extreme heat immediately after treatment, and not lying flat for 4 hours post-treatment all support the best results. Some practitioners also find that combining anti-wrinkle injections with skin quality treatments like polynucleotides improves overall outcomes.

When should you book your top-up?

The ideal time to book your top-up is when movement is just beginning to return — around 10–12 weeks for most clients. Waiting until the product has completely worn off means the muscle rebuilds to full strength, making the next treatment less effective. At ReGen Aesthetics Clinic in Merthyr Tydfil, we recommend scheduling your follow-up in advance so you're not waiting for availability when you need it.

Why consistency matters more than frequency

Many clients ask whether they can stretch treatments to save money. While this is understandable, maintaining consistent treatment intervals actually produces better long-term results — and can mean you need less product over time as muscles weaken progressively with regular relaxation. Think of it as a long-term investment in your skin, not just a one-off treatment.
