Quick answer: Ultherapy PRIME, fillers, and Botox treat three different problems. Ultherapy PRIME lifts and tightens sagging skin by building collagen. Fillers add volume where it’s been lost. Botox relaxes the muscles causing expression lines. Many people need a combination, not one instead of the others.
This is one of the most common points of confusion in aesthetic medicine, and it’s an easy mix-up: all three are marketed as “anti-ageing” treatments, so people assume they’re competing options. They’re not. Each one does something the others can’t.
The Core Difference in One Table
| Ultherapy PRIME | Dermal Filler | Botox | |
|---|---|---|---|
| What it treats | Sagging, loose skin | Lost volume, hollows, folds | Muscle-caused expression lines |
| How it works | Heat stimulates your own collagen | Injectable gel physically fills space | Relaxes the muscle beneath a wrinkle |
| Best for | Jawline, jowls, neck, brow laxity | Cheeks, lips, under-eye hollows, nasolabial folds | Forehead lines, frown lines, crow’s feet |
| Onset | Gradual, over 2–6 months | Immediate | 3–7 days |
| Downtime | None | Minimal | None |
| Typical duration | 12–18 months | 6 months–2 years, product-dependent | 3–4 months |
Ultherapy PRIME: For Sagging, Not Volume Loss
Ultherapy PRIME uses micro-focused ultrasound with real-time imaging to heat tissue at precise depths, including the SMAS layer targeted in a surgical facelift. That controlled heat triggers new collagen and elastin, gradually lifting and tightening skin.
Ask yourself: does your skin feel loose or droopy, rather than thin or hollow? If your jawline has lost definition, your jowls are starting to sag, or your neck feels crepey, that’s a laxity problem. Filler and Botox don’t fix laxity, because neither one tightens skin.

Dermal Fillers: For Lost Volume
Fillers, usually hyaluronic acid, are injected to physically add volume where your face has lost it: hollow cheeks, thin lips, a hollow under-eye, or a deep nasolabial fold.
Ask yourself: does an area of your face look sunken, flat, or hollow, rather than just loose? Volume loss and sagging often look similar in a mirror but need different treatments. A hollow cheek needs filler; a sagging jowl needs lifting.
See our dermal fillers guide for the full range of options.
Botox: For Expression Lines, Not Sagging or Hollowing
Botox relaxes the specific muscle causing a wrinkle. It only works on dynamic wrinkles, lines caused by repeated movement, like frown lines, forehead lines, and crow’s feet.
Ask yourself: does the line only appear when you make an expression, and disappear when your face is relaxed? That’s a Botox problem. If the line or fold is visible even at rest, Botox alone won’t fully address it, since the cause isn’t muscle movement.

A Quick Self-Check
| If your concern is… | You likely need… |
|---|---|
| A sagging jawline or jowls | Ultherapy PRIME |
| A crepey, loose neck | Ultherapy PRIME |
| Hollow cheeks or under-eyes | Filler |
| Thin lips | Filler |
| Deep nasolabial folds (at rest) | Filler, sometimes with Ultherapy PRIME for the cheek above it |
| Forehead lines when you raise your eyebrows | Botox |
| Frown lines between your brows | Botox |
| Crow’s feet when you smile | Botox |
| “My whole face looks tired” | Often a combination of all three |
Why People Often Need More Than One
Ageing rarely affects a face in just one way. It’s common to have sagging in the jawline, volume loss in the cheeks, and expression lines on the forehead, all at once, which is exactly why these three treatments are frequently combined rather than chosen as alternatives.
A typical combined plan might use Ultherapy PRIME to lift the jawline and neck, filler to restore cheek volume, and Botox for the forehead and crow’s feet, addressing three separate causes in one visit or a short series of appointments. A clinical overview of combination approaches to facial rejuvenation, published in PubMed Central, supports treating the different layers and causes of facial ageing together rather than relying on a single modality.
What Order Should They Be Done In?
There’s no universal rule, but a common approach is:
- Ultherapy PRIME first, since it can take months to show full results, and starting early means results develop while other treatments are still fresh
- Filler next, once any structural lift from Ultherapy PRIME has had time to settle
- Botox can generally be done at any point, since it works independently of the others
Your doctor will confirm the right order and timing based on your specific combination.
Frequently Asked Questions
Is Ultherapy PRIME better than filler? Neither is “better,” they treat different problems. Ultherapy PRIME lifts sagging skin; filler adds volume to hollow areas. Many people need both.
Can I get Ultherapy PRIME and Botox on the same day? Yes, generally. They work through different mechanisms (heat-triggered collagen versus muscle relaxation) and don’t interfere with each other.
Will Botox tighten my jawline? Not in the way Ultherapy PRIME does. Botox can slim an overactive jaw muscle (masseter), which changes jaw shape, but it doesn’t tighten loose, sagging skin.
Can filler fix a sagging jawline? Filler can restore lost volume that contributes to jaw definition, but it can’t tighten skin that’s genuinely loose. If sagging is the main issue, Ultherapy PRIME addresses that directly.
I don’t know if my concern is volume loss or sagging, how do I check? A simple test: gently push the loose or hollow-looking area upward with your finger. If pushing it up makes the area look better and more youthful, that often points to sagging (Ultherapy PRIME or a lift). If pushing doesn’t help because the area is genuinely sunken, that points to volume loss (filler). A consultation gives a more reliable answer.
Do results from all three look the same? No. Ultherapy PRIME gives a gradual, natural lift over months. Filler gives an immediate, visible change. Botox softens a specific line within days. Combined, they can address more of the face than any one alone.
Bottom Line
Ultherapy PRIME, fillers, and Botox aren’t competing treatments, they’re tools for three different problems: sagging, volume loss, and expression lines. Working out which one (or which combination) your face actually needs starts with identifying which of these three you’re dealing with. At CLEO Clinic, a proper facial assessment identifies this before any treatment is recommended. Book a consultation to find out what your face actually needs.
