Injectables and skin rejuvenation: what each treatment actually does
How Botox, dermal fillers, HydraFacial and skin boosters actually work, what each treats, how long results last, realistic risks, and how to choose a physician-led clinic in Dubai.
Last medically reviewed: 1 August 2026
Aesthetic medicine has a marketing problem: treatments are sold as brands rather than explained as procedures. This guide describes what each treatment does biologically, what it genuinely treats, and how to evaluate a clinic.
Everything below is physician-led treatment. These are medical procedures with medical risks, not beauty services.
Botulinum toxin (Botox)
What it does
A purified protein that temporarily blocks the nerve signal to a specific muscle. The muscle relaxes, and lines caused by that muscle contracting soften.
What it treats well
- Frown lines between the brows
- Horizontal forehead lines
- Crow’s feet
- A “gummy smile” caused by a hyperactive upper lip muscle
- Jaw clenching and bruxism — clinically relevant for our dental patients, since it protects teeth and restorations
- Excessive underarm sweating
What it does not treat
Lines present when your face is completely at rest are usually static lines caused by volume loss and skin quality — not muscle movement. Botox will not remove them. Filler, skin boosters or resurfacing address those. A clinic that offers Botox for everything is not diagnosing.
Timeline
Onset begins at three to five days, with full effect at two weeks. Duration is three to four months. A review at two weeks allows small adjustments.
Dermal fillers
What they do
Most modern fillers are hyaluronic acid — a substance the body produces naturally. Injected into specific tissue planes, they restore volume and support structure.
What they treat
- Cheek volume loss, which is often the true cause of a tired appearance
- Deepened nasolabial folds and marionette lines
- Lip volume and definition
- Chin and jawline definition
- Under-eye hollowing — a technically demanding area requiring genuine expertise
The principle that matters
Facial ageing is largely volume loss and descent, not just wrinkles. Chasing individual lines with filler produces distorted results. Restoring support where volume was lost produces natural ones. This is why assessment considers the whole face rather than the line you point at.
Safety
The serious risk is vascular occlusion — filler entering or compressing a blood vessel, which can cause tissue loss or, rarely, visual complications. This is why injector training and anatomical knowledge matter more than product brand. Ensure your clinic:
- Uses hyaluronic acid products that can be dissolved
- Keeps hyaluronidase on site
- Is led by a qualified medical practitioner
Skin boosters
Skin boosters such as Profhilo are not volumising fillers. They are injected hyaluronic acid formulations that hydrate the dermis and stimulate collagen and elastin. They improve skin quality — texture, hydration and laxity — rather than adding contour.
Typical protocol: two sessions four weeks apart, then maintenance every six months.
HydraFacial
A device-based treatment combining cleansing, gentle exfoliation, extraction and infusion of serums. No downtime, immediate radiance, and it suits most skin types.
Combining HydraFacial with skin boosters works well: the facial addresses the skin surface and immediate luminosity, while boosters improve the dermis over weeks. The legacy clinic guidance highlights this pairing for hydration and fine lines, and the reasoning is sound — they operate at different depths.
Microneedling
Controlled micro-injury triggers the skin’s repair response, generating new collagen. Effective for texture, acne scarring and pore appearance. A course of three to six sessions spaced four weeks apart is typical, with mild redness for one to two days after each.
Choosing sensibly
| Your concern | Likely treatment |
|---|---|
| Lines only when I move my face | Botulinum toxin |
| Lines at rest, flattened cheeks | Dermal filler |
| Dull, dehydrated, crepey skin | Skin boosters, HydraFacial |
| Texture, scarring, large pores | Microneedling |
| Immediate event-ready glow | HydraFacial |
Most good plans combine two modalities over time rather than overloading one.
Questions to ask before treatment
- Who is performing it, and what are their medical qualifications?
- Which product is being used, and is it reversible?
- Is hyaluronidase available on site?
- What is the plan if I dislike the result?
- Is there a review appointment included?
A clinic that cannot answer these directly is not the right clinic.
Our approach
We treat conservatively and review. Starting with a modest dose and adding at review is safer than reversing an overtreatment. Assessment is of the whole face, and if the honest answer is that a treatment will not achieve what you want, we say so at consultation.
Frequently asked questions
What is the difference between Botox and fillers?
They do opposite things. Botox relaxes a muscle to soften lines caused by movement — frown lines, forehead lines, crow's feet. Fillers add volume to restore structure that has been lost, such as cheek projection or deepened folds. Many treatment plans use both because they address different problems.
How long do results last?
Botox typically lasts three to four months. Hyaluronic acid fillers last six to eighteen months depending on the product and the area treated. Skin boosters such as Profhilo are usually given as an initial course of two sessions, then maintained every six months.
Will I look frozen or overdone?
That result comes from excessive dosing and ignoring facial dynamics. Conservative, anatomy-led dosing preserves expression while softening lines. It is easier to add a small amount at review than to reverse an overtreatment, so we deliberately start conservative.
Are dermal fillers reversible?
Hyaluronic acid fillers can be dissolved with hyaluronidase, which is an important safety feature. This is one reason we work with HA products in most cases. Permanent fillers do not offer this and carry substantially higher long-term risk.
