What Are Dermal Fillers

Dermal fillers are injectable gels placed beneath the skin to restore volume, smooth folds, or reshape features. The most common type is made from hyaluronic acid and lasts 6-18 months. You can explore the full dermal fillers treatment overview for more. If you have seen the before-and-afters, heard the buzzwords, and wondered whether fillers are right for you - this guide explains what you actually need to know. By the end, you will know how the main types differ, where they get used, what the experience feels like, what they cost in Dubai, and exactly what to ask before committing to a single syringe.

What dermal fillers are

Fillers are not the same as anti-wrinkle injections (botulinum toxin). Botulinum toxin relaxes muscles to soften expression lines; fillers physically add volume or structure. The two are often used together, but they work through completely different mechanisms.1

Most fillers are made from materials that occur naturally in the body or break down safely over time. The vast majority are temporary - your body gradually metabolises them, and the effect fades. That reversibility is both a feature and a limit worth understanding.

Types of dermal fillers: HA, CaHA, and PLLA

Not all fillers are the same gel. Three material families dominate the market, each with different mechanisms, longevity, and best-use cases.

Hyaluronic acid (HA)

Hyaluronic acid is a sugar molecule found naturally in skin and connective tissue. Its job in the body is to attract and hold water - up to 1,000 times its weight.2 HA fillers replicate that hydrating, volumising effect in a precise location. They are the most widely used filler type globally, come in a range of thicknesses (called rheologies), and - crucially - can be dissolved with an enzyme called hyaluronidase if a result is not right. Major brands you will encounter include Juvederm (Allergan Aesthetics) and Restylane (Galderma). Duration is typically 6-18 months depending on product, area, and individual metabolism.1

Calcium hydroxylapatite (CaHA)

Calcium hydroxylapatite is a mineral compound found in bone. In filler form (the main brand is Radiesse), it is suspended in a gel carrier. Once injected, the gel provides immediate volume while the CaHA microspheres stimulate your own collagen production over time. It is thicker than most HA fillers, suits deeper structural work (jawline, cheeks, hands), and lasts roughly 12-18 months. It cannot be dissolved with hyaluronidase, so precise placement by an experienced practitioner matters more.1

Poly-L-lactic acid (PLLA)

Poly-L-lactic acid is a synthetic, biocompatible material that has been used in dissolvable sutures for decades. As a filler (the main brand is Sculptra), it works as a biostimulator - it does not add instant volume but gradually triggers collagen synthesis over several weeks. Results build slowly across multiple sessions and can last two or more years. PLLA suits people looking for gradual, diffuse volume restoration rather than immediate contouring. It is not a good fit for fine surface lines or precise feature reshaping.1

What fillers treat - and what they do not

Who fillers suit - and who should pause

Fillers are suitable for most healthy adults who want volume restoration or contouring. That said, certain situations call for caution or an alternative approach.

• Pregnancy and breastfeeding: Most practitioners defer treatment until after this period; safety data is limited.1
• Active skin infection or inflammation at the injection site: Treatment should be postponed.
• Autoimmune conditions or blood-thinning medications: Disclose these in full at consultation - some require a modified plan or medical sign-off.
• History of cold sores (herpes simplex): Lip filler can trigger an outbreak; prophylactic antiviral treatment is often recommended.3
• Unrealistic outcome expectations: Fillers reshape and restore; they do not stop ageing or replicate surgery.

Fillers on darker skin tones (Fitzpatrick IV-VI)

Dubai's population skews toward Fitzpatrick skin types IV-VI, and this matters for fillers in two specific ways. First, the risk of post-inflammatory hyperpigmentation (PIH) - darkening at injection points - is higher in deeper skin tones. An experienced practitioner will use fine needles or cannulas, minimise bruising, and apply appropriate aftercare. Second, volume loss and facial ageing patterns differ across ethnic backgrounds, so assessment and placement need to be calibrated accordingly rather than following a template designed for lighter skin.4 Ask your practitioner about their specific experience with your skin tone before you book.

What the experience looks like

Consultation

A proper consultation involves a full facial assessment, discussion of your goals, review of your medical history, and a clear explanation of which product and technique the practitioner recommends - and why. A good consultation will cover the 'why' behind any product or technique recommendation, not just the booking logistics.

The procedure

Most filler sessions take 20-45 minutes. A topical numbing cream is usually applied for 15-20 minutes beforehand, and many HA fillers also contain lidocaine (a local anaesthetic) within the gel itself.2 Injections are placed with either a needle or a blunt-tipped cannula - the choice depends on the area and the practitioner's technique. You will typically see results immediately, though swelling in the first 24-48 hours means the settled result takes a few days to reveal itself.

Aftercare

• Avoid intense heat (saunas, steam rooms, direct sun exposure) for 24-48 hours - relevant in Dubai's climate.
• Skip strenuous exercise for 24 hours to reduce swelling and bruising.
• Do not massage or apply pressure to treated areas unless specifically instructed to.
• Avoid alcohol for 24 hours to minimise bruising.
• Sleep on your back for the first night if lips or cheeks were treated.

What to expect afterwards

Common side effects include swelling, redness, and mild bruising at injection sites - these typically resolve within a few days to two weeks.3 More significant side effects are uncommon but exist: nodules (small lumps under the skin), asymmetry, and in rare cases vascular complications if filler is inadvertently injected near a blood vessel. This is why practitioner credentials and experience are not a detail to skip over. Ask specifically about how your practitioner manages complications and what their protocol is if you are unhappy with the result.

What fillers cost in Dubai

Filler is typically priced per syringe or per area. The two are not the same - some areas need more than one syringe, and some clinics bundle product into an area price. Get clarity on what you are being quoted before you compare.

What drives the range: the practitioner's qualifications and experience, the specific product used (a premium Juvederm line costs more than an entry-level HA product), whether the clinic operates a medical-director model, and location. A significantly lower price is worth questioning - ask which specific product is being used and verify the practitioner's credentials.

Questions to ask in your consultation

How to read filler marketing claims

Aesthetic marketing uses specific vocabulary that is worth understanding before you book.

• 'Natural-looking results' is a technique claim, not a product claim. Any filler can look natural or overdone depending on how much is used and where. Ask the practitioner for their approach to conservative treatment.
• 'The latest filler' is not evidence of superiority. Newer is not automatically better. Juvederm and Restylane have extensive clinical track records; a novel brand with limited data warrants more scrutiny, not less.
• Duration claims vary widely. '18-month results' in a clinical trial may not match your metabolism. Individual variation is significant.
• Package deals that combine multiple syringes upfront can create pressure. It is reasonable to start with one session and assess before committing to more.
• Before-and-after photos show best-case outcomes. Ask how representative they are and whether lighting, filters, or makeup were controlled.
