The art ofinvisible restoration
Your comprehensive guide to dermal fillers. Understanding hyaluronic acid, how it restores volume, and achieving results so natural they're undetectable.
At CosmeDocs, fillers are placed with precision and restraint. GMC-registered doctors assess your face as a whole, restoring balance — never altering identity. Since 2007, our philosophy has been invisible art.
A naturally occurring substance in skin that retains moisture and provides structural support.
"Everyone says I look amazing but they can't put their finger on why. That's the sign of truly excellent work."
More real experiencesWhat Are Dermal Fillers?
Dermal fillers are injectable treatments most commonly made from hyaluronic acid — a substance naturally found in the skin that helps retain hydration, volume, and elasticity. As we age, the face loses structural support — bone recedes, fat pads shift, and skin becomes thinner. Dermal fillers work by restoring this lost volume, lifting sagging tissues, and softening lines — without surgery.
How Dermal Fillers Work
Assessment
Your doctor analyses facial anatomy, bone structure, and volume loss patterns to create a bespoke treatment plan.
Injection
Hyaluronic acid gel is precisely placed using cannulae or fine needles at specific depths to restore or enhance volume.
Integration
The filler integrates with surrounding tissue, drawing moisture and providing natural-looking support and structure.
Treatment Areas
Each area of the face has unique anatomy, ageing patterns, and requirements. Our doctors tailor product choice, placement depth, and volume to each individual area.
Lips
The most popular filler treatment, from subtle definition to fuller volume.
- Volume Enhancement
- Shape Definition
- Cupid's Bow
- Natural Plumping
Mid-Face
Restoring mid-face support and addressing volume loss that contributes to an aged appearance.
- Cheek Volume
- Tear Trough
- Temple Hollowing
- Nasolabial Folds
Lower Face
Structural contouring for a more defined, balanced lower face.
- Jawline Definition
- Chin Projection
- Marionette Lines
- Jowl Support
Specialist
Targeted treatments for specific concerns and refinements.
- Non-Surgical Nose Job
- Forehead Smoothing
- Ear Lobe Rejuvenation

A Full-Face Approach
Facial ageing does not occur in isolation. Lines, folds, and hollowing are often the result of structural changes elsewhere in the face. That's why our doctors adopt a full-face approach — assessing how different regions interact, and how restoring support in one area can naturally improve another.
Who Is Suitable?
Enhancement
For those seeking to enhance facial features — lip volume, cheek definition, jawline contouring — regardless of age.
Restoration
For age-related volume loss — hollow cheeks, deep nasolabial folds, thinning lips, temple hollowing. Restoring what time has taken.
Results Timeline
Day 1: Immediate
Visible improvement straight away. Some swelling is normal and expected — this settles within 48–72 hours.
Weeks 2–4: Settled
Swelling fully resolved. The filler has integrated with tissue and hydrated. This is when you see the true result.
Months 12–18: Duration
Results typically last 12–18 months depending on the area, product used, and individual metabolism.
How Fillers Fit Into Facial Rejuvenation
Understanding the difference between dermal fillers and Botox helps you make informed decisions about your treatment plan.
Choosing a Clinic
Dermal fillers require deep understanding of facial anatomy. The difference between natural results and overfilled outcomes comes down to practitioner skill.
Safety & Your Consultation
Hyaluronic acid fillers have an excellent safety profile. They are biocompatible, temporary, and — importantly — fully reversible using an enzyme called hyaluronidase.
The Filler Migration Myth
"Filler migration" is one of the most commonly repeated concerns in aesthetics — but it's largely a misconception. Hyaluronic acid filler, when placed correctly by an experienced practitioner, integrates with the surrounding tissue and stays precisely where it's injected.
