If you’re considering your first aesthetic treatment, or your next one, you’ve probably wondered whether Botox or dermal fillers are the right fit for you. They’re the two most requested treatments in aesthetics, and they’re often talked about interchangeably, but they work in completely different ways and solve different problems.

At iSkincare, Poole and Bournemouth’s nurse-led aesthetic clinic, Rachael and Sofia are asked this question in almost every consultation. Here’s the honest breakdown, so you can walk into your own consultation already understanding the basics.

What Does Botox Actually Do?

Botox, and its alternatives Azzalure and Alluzience, is a purified form of botulinum toxin type A. It works by temporarily relaxing the muscles responsible for “dynamic” wrinkles, the lines that form from repeated facial movement, such as frowning, squinting or raising your eyebrows.

Botox is a prescription only medicine, which means a face to face medical consultation with a qualified prescriber is a legal requirement before any treatment, never a video call, never a quick online form.

What Do Dermal Fillers Actually Do?

Dermal fillers work completely differently. Rather than relaxing muscles, they restore lost volume and structure using hyaluronic acid, a substance your skin already produces naturally. As we age, we lose volume in the cheeks, temples, lips and jawline, and fillers are used to replace it, softening static lines and restoring a more youthful contour.

At iSkincare, treatments use Juvederm, one of the world’s most established hyaluronic acid filler ranges, chosen for its natural finish and predictable, long-lasting results.

The Key Difference: Movement vs Volume

This is the simplest way to think about it. Botox treats lines caused by movement. Dermal fillers treat volume loss and lines caused by structural changes to the face. Neither is “better” than the other, they’re simply designed to solve different problems, and many patients benefit from both, used in different areas.

Can You Have Both?

Yes, and it’s extremely common. A typical treatment plan might use Botox on the forehead and around the eyes, where movement causes lines, combined with dermal filler in the cheeks or nasolabial folds, where volume has been lost. This combined approach is often what creates the most natural, well-balanced result, rather than treating the whole face with just one product.

How Long Do Results Last?

This is one of the most practical differences between the two, and something worth factoring into your decision alongside the aesthetic result you’re after.

Which One Is Right for You?

• If your main concern is lines that appear when you frown, smile or raise your eyebrows, Botox is usually the starting point.
• If your main concern is lost volume, hollowing, or static lines visible even when your face is relaxed, dermal fillers are usually more appropriate.
• If you’re not sure, that’s completely normal, and exactly what a proper consultation is for.

Why a Proper Consultation Matters

Both Botox and dermal fillers are medical treatments, not beauty treatments, and both carry real risks when administered without proper training. At iSkincare, every treatment plan starts with a full consultation with Rachael or Sofia, both Independent Nurse Prescribers, covering your medical history, facial anatomy, goals and any contraindications, before any product is discussed, let alone injected.

This is also where the “which one do I need” question gets properly answered, based on your face, not a generic guide like this one.

Why Choose iSkincare for Botox and Dermal Fillers?

Rachael and Sofia are a mother-daughter team of Independent Nurse Prescribers, treating patients across Poole, Bournemouth and Dorset. Every consultation, treatment and review is delivered personally by one of them, never handed off to a different practitioner partway through your journey.

Botox and Dermal Filler FAQs

Can I have Botox and fillers on the same day?

Yes, many patients have both in a single appointment, treated in different areas based on their consultation.

Which lasts longer, Botox or dermal fillers?

Dermal fillers generally last longer, 9 to 24 months depending on the product, compared to 3 to 4 months for Botox.

Is Botox or filler better for under eye bags?

This depends on the cause. Volume loss under the eyes is usually treated with filler, while fine lines from squinting may respond better to Botox. This is best assessed at consultation.

Do I need to see a doctor for Botox or can a nurse do it?

Independent Nurse Prescribers, like Rachael and Sofia, are fully qualified to prescribe and administer Botox and dermal fillers, and are a common and highly experienced choice across the UK.

This article is for general information and does not replace a full medical consultation. Botox is a prescription only medicine and requires a face to face consultation with a qualified prescriber before treatment.
