Filler Treatments
Frequently Asked Questions
How long do dermal fillers last?
Dermal fillers with hyaluronic acid typically last 6 to 18 months depending on the area. Lip fillers last 6–12 months, while cheek and jawline fillers can last 12–18 months. High-movement areas metabolize product faster.
Are dermal fillers safe?
Yes, hyaluronic acid fillers are one of the safest aesthetic treatments available. Hyaluronic acid is a substance naturally found in your body. At Cosmo Clinic, all treatments are performed by licensed aesthetic physicians using CE-marked products from established brands.
What's the difference between lip filler and cheek filler?
Lip filler adds volume, definition, and hydration to the lips using small amounts of hyaluronic acid. Cheek filler restores lost volume in the midface, lifting the cheeks and improving overall facial harmony. Both use the same material but require different techniques.
Is lip filler painful?
Lip filler is well-tolerated. We apply numbing cream before treatment, and the filler products contain built-in anaesthetic. Most patients describe a mild pressure sensation that subsides immediately after the procedure.
Can fillers be reversed?
Yes. Hyaluronic acid fillers can be dissolved with hyaluronidase, an enzyme that safely breaks down the filler within 24-48 hours. This reversibility makes hyaluronic acid fillers one of the safest options in aesthetic medicine.
How to choose the right filler for your face
Hyaluronic acid fillers restore volume, define contours and soften folds — but each area calls for a different gel density and elasticity. The product used for a jawline is not the one used for lips or under-eyes. That is why the choice starts with a medical assessment, not with a product name.
By facial area
For volume and definition: lips, cheekbones, jawline and chin. To soften folds and shadows: under-eye, nasolabial folds, marionette lines and barcode lines. For profile harmonisation: nose filler (non-surgical rhinoplasty) and temples.
The essentials of hyaluronic acid
Hyaluronic acid occurs naturally in the skin, which makes it biocompatible and — importantly — reversible: if ever needed, it can be dissolved with hyaluronidase. Results are visible immediately and build gradually. We would rather start conservative and top up at a second session than overfill on day one. For a deeper read, see our facial fillers guide.
Filler, or a different approach?
Not everything is solved with volume. If skin quality is the issue, skin treatments may be the better route — the comparison biostimulators vs filler explains the difference. For lips, there is also the subtle alternative of the lip flip. Aftercare questions? Our lip filler aftercare guide covers the first two weeks day by day.
Frequently asked questions
How long does filler last? Between 6 and 18 months depending on the area, product and metabolism. High-movement areas such as lips break down faster. Results vary by individual.
Will it look natural? With appropriate dosing, yes — the goal is to restore proportion, not transform the face. Our English-speaking medical team walks you through expected outcomes before treating.
Is it reversible? Yes. Hyaluronic acid fillers can be dissolved by a physician using hyaluronidase — one of the reasons they are considered among the safest options in aesthetic medicine.
