The Science Behind Dermal Fillers: How They Restore Youthful Skin
When it comes to non-surgical facial rejuvenation, dermal fillers have become a go-to treatment for restoring volume, smoothing lines, and enhancing natural contours. But what exactly are dermal fillers, how do they work, and why are they so effective? In this blog, we dive into the science behind dermal fillers and how they can help you achieve natural, youthful results.
What Are Dermal Fillers?
Dermal fillers are injectable gels used to replace lost volume in the skin and enhance facial features. Most modern fillers are made from hyaluronic acid (HA), a substance naturally found in the body that helps retain moisture and keep skin plump and hydrated.
Common Uses for Dermal Fillers:
Cheek enhancement – to restore volume and lift
Nasolabial folds – to smooth deep lines from nose to mouth
Marionette lines – to reduce downward lines from the corners of the mouth
Lips – for volume, definition, and hydration
Jawline & chin – for contouring and facial balance
Tear troughs – to reduce hollowness under the eyes
How Do Dermal Fillers Work?
As we age, our skin loses collagen, elastin, and hyaluronic acid, leading to volume loss, sagging, and wrinkles. Dermal fillers work by injecting HA-based gels beneath the skin to replenish lost volume and stimulate collagen production.
Depending on the thickness of the filler and the treatment area, results can range from subtle hydration to dramatic contouring. The filler provides immediate volume and support, while also encouraging long-term skin rejuvenation.
Benefits of Hyaluronic Acid Fillers:
✔ Naturally found in the body ✔ Hydrates and plumps the skin ✔ Biodegradable and reversible ✔ Safe and effective with minimal downtime
The Different Types of Fillers
There are many brands and formulations of dermal fillers, each suited for specific purposes. At A for Aesthetics, we only use premium, clinically tested products to ensure safety and optimal results.
Lightweight fillers – Ideal for fine lines, lip hydration, and delicate areas like tear troughs
Medium-density fillers – Great for nasolabial folds and moderate volume loss
Thicker fillers – Used for deep volumisation in cheeks, jawline, or chin
What to Expect During a Filler Treatment
Consultation: Your practitioner will assess your facial structure, listen to your concerns, and create a personalised treatment plan.
Preparation: The area is cleaned and numbing cream may be applied to reduce discomfort.
Injection: Using precise techniques, the filler is injected into targeted areas.
Aftercare: Mild swelling or bruising may occur but usually resolves within a few days.
The entire treatment typically takes 30–60 minutes, and results are visible immediately, with improvements continuing as swelling settles.
How Long Do Results Last?
Dermal filler longevity depends on the area treated and the type of filler used, but results generally last 6 to 18 months. Areas with more movement (like lips) may break down filler faster than more static areas (like cheeks).
Are Dermal Fillers Safe?
Yes—when administered by a qualified and experienced aesthetic practitioner. Side effects are usually mild and temporary, including redness, swelling, or slight bruising.
One of the benefits of HA fillers is that they are reversible. If needed, an enzyme called hyaluronidase can be used to dissolve the filler safely.
