If you have been looking into facial aesthetic treatments and found yourself confused by the difference between Botox and fillers, you are in good company. The two terms are often used interchangeably online, sometimes even by clinics that should know better, but they are not the same thing; they do not treat the same problems, and choosing the wrong one for your concern will leave you disappointed.

At Roseacre Dental in Maidstone, facial aesthetics treatments are carried out by dental professionals with a detailed understanding of facial anatomy. Here is a clear explanation of what separates these two treatments and how to know which one, if either, might be appropriate for you.

What Botox does

Botox (botulinum toxin type A) is a muscle relaxant. Injected in very small quantities into specific facial muscles, it temporarily reduces the strength of those contractions. The result is that the lines caused by repeated facial movements squinting, frowning, and raising the eyebrows, soften because the underlying muscle is no longer pulling the skin as forcefully.

It works best on dynamic wrinkles: lines that appear or deepen when you make an expression.

The most common treatment areas are:

• Forehead horizontal lines
• The vertical frown lines between the eyebrows (glabellar lines)
• Crow’s feet at the outer corners of the eyes

Results appear within a few days and last around three to four months, sometimes longer with repeated treatment.

What dermal fillers do

Dermal fillers are injectable gels most commonly made from hyaluronic acid, a substance that occurs naturally in the body, that add volume, lift, or definition to specific areas of the face.

As the face ages, it loses fat, collagen, and bone density. Cheeks become flatter, the under-eye area can hollow, nasolabial folds (the lines running from the nose to the corners of the mouth) deepen, and the jawline becomes less defined. These changes are not caused by muscle movement; they are caused by volume loss. Botox cannot address them. Filler can.

Common filler treatment areas include:

• Cheeks and mid-face for lost volume and lift
• Nasolabial folds and marionette lines
• Lips for definition or subtle enhancement
• Jawline and chin for improved structure
• The under-eye (tear trough) area is a more technically demanding area requiring an experienced practitioner

Most hyaluronic acid fillers last between six and eighteen months, depending on the product used, the area treated, and the individual’s metabolism.

Can you have both at the same time?

Yes, and for many patients this produces the best overall result. A combination approach, sometimes called a liquid facelift, uses Botox to address dynamic lines in the upper face and filler to restore volume in the mid and lower face. The two treatments complement each other rather than competing.

That said, combination treatment is not always necessary or appropriate. Some patients need only one or the other. A good consultation should help you understand what your specific concerns actually require, not push you towards more treatment than you need.

The Safety Question and why it matters

This is important. In the UK, botulinum toxin (Botox) is a prescription-only medicine. It can only be legally prescribed by a doctor, dentist, nurse prescriber, or pharmacist. This gives it a meaningful level of regulatory protection.

Dermal fillers, however, are currently not prescription-only in the UK. This means that, legally, anyone can buy and inject them. The result is a significant variation in safety standards across the industry, from highly skilled medical practitioners to people with minimal training operating from beauty salons.

The government has announced plans to introduce stricter regulation of fillers in England, but as of 2026, the gap in oversight remains.

Choosing a qualified dental or medical professional for any injectable treatment significantly reduces your risk of complications, which, while rare in skilled hands, can be serious when fillers are misplaced.

How to decide which treatment is right for you

Ask yourself: what specifically bothers me?

• Lines that appear when I smile or frown, but are less visible when my face is at rest? That points to Botox.
• Areas that look flat, hollow, or have lost their shape even when my face is relaxed? That points to fillers.
• Both? A combination approach might be worth discussing.

The most reliable way to know is to have a proper consultation with a qualified practitioner who will assess your face, understand your concerns, and give you an honest recommendation, including telling you if neither treatment is the right solution.

FAQ

Do Botox or fillers look more natural?
Both can look completely natural when administered correctly and in appropriate amounts. The “done” look associated with either treatment is usually the result of overtreatment or poor technique, not the products themselves.

Is Botox or fillers more painful?
Both involve injections. Botox injections use a very fine needle, and most patients find them very tolerable. Filler injections vary by area; lips, for example, tend to be more sensitive. Most practitioners use a topical numbing cream beforehand.

Can Botox and fillers be reversed?
Botox cannot be reversed, but it will wear off naturally within a few months. Hyaluronic acid fillers can be dissolved with an enzyme called hyaluronidase, which is an important safety net if results are not as expected.

Who should not have Botox or fillers?
These treatments are not suitable during pregnancy or breastfeeding, for patients with certain neuromuscular conditions, or for those with active skin infections in the treatment area. A thorough medical consultation will identify any contraindications.
