And while topical products can help improve surface hydration, there is also a more effective way for hyaluronic acid to help with anti-ageing and that is through the use of injectables, most commonly as hyaluronic acid-based dermal fillers. 

What Are Hyaluronic Acid Fillers and How Do They Work?

Hyaluronic acid plays a huge role in the hydration and elasticity of our skin. It’s a naturally occurring substance that is found in our skin, joints, and connective tissue. Hyaluronic acid’s primary function is to retain moisture and keep these tissues hydrated and plump. But as we age, our body’s natural HA levels decrease, which leads to visible aging signs manifested as wrinkles,  sagging, and skin dryness. 

Dermal fillers help counteract this by injecting hyaluronic acid into the skin and instantly adding volume and hydration back to the areas lacking it. 

Common Areas Treated with HA Fillers

Hyaluronic acid fillers are incredibly versatile and can be used to treat a range of areas on the face, including:

• Nasolabial folds (also known as smile lines) and marionette lines around the mouth

• Lips, to add volume

• Cheeks and cheekbones, to restore lost volume or add more definition

• Jawline and chin, to improve contour and facial symmetry

• Under-eye area, to reduce the appearance of dark circles and hollowness

Types of HA Fillers Available

Not all HA fillers are the same. Different brands use their trademarked technologies to create varying gel consistencies, making certain products more suitable for specific areas of the face.

Popular brands like Juvederm have a smoother, more cohesive gel texture that works well for volumizing larger areas like the cheeks and lips, offering results that can last up to 12–18 months (depending on the product line).

On the other hand, there are brands like Restylane and Stylage, which provide a slightly firmer texture ideal for structural support in areas like the nasolabial folds or jawline, while still maintaining natural movement.

Of course, there are many other brands on the market. For example, Saypha is a well-known brand that gives reliable results at a fair price. It works well for both shallow injections, like fine lines, and deeper ones for wrinkles or adding volume. Many practitioners like it because it’s easy to use and gives natural-looking results.

The choice is truly wide and diverse, but that can sometimes make it overwhelming, especially for people who are considering trying out their first filler injections. This is why having a consultation with the treatment provider is so crucial, as they can asses each client’s needs and choose the best filler selection based on the treatment area, skin condition, and desired results.

Benefits of HA Fillers

Hyaluronic acid fillers are the most commonly used type of dermal fillers because of all the benefits they provide. 

One of their biggest advantages is instant, natural-looking results. Immediately after the treatment, patients can see visible improvements in volume, contour, and smoothness of their skin. 

Because hyaluronic acid is already found in the body, these fillers are biocompatible and well tolerated, with a very low risk of allergic reaction. They’re also versatile, allowing providers to tailor custom treatments depending on the thickness and placement of the filler. This means hyaluronic acid-based filler can address everything from fine lines to deeper folds or areas needing more structural support.

Another key advantage is that HA fillers are temporary and reversible, which means adjustments can be made if needed. This makes them especially appealing to first-time patients who may feel more comfortable knowing the effects aren’t permanent.

What to Expect During and After the Procedure

A typical dermal filler session takes about 20 to 45 minutes, depending on the number of areas treated and whether or not numbing prior to the procedure is required. Most modern fillers already contain lidocaine (a local anesthetic) to minimize discomfort during the injection process. However, some formulas are specifically designed without it, due to individual sensitivities.

In these cases, or cases where the client has very little pain tolerance and wants to prevent any discomfort, numbing cream will be applied as part of the preparation step. The numbing cream has to sit for about 15-20 minutes before it’s wiped off and the procedure can begin.

The injection process itself is quick and involves the use of a fine needle (for precise injection, for areas like lips) or cannula (for spreading an even layer across larger areas, like cheeks). Most patients report feeling only minimal pressure or a slight pinch.

After treatment, some mild swelling, redness, or bruising may occur, but these side effects usually resolve on their own within a few days. Most patients resume their regular activities immediately after the procedure, which makes HA fillers quite a convenient option for those with busy schedules.

Longevity and Maintenance

On average, these kinds of dermal fillers tend to last between 6 to 18 months. The longevity depends on the specific product used as well as the area where it was injected. Areas with more movement, like the lips, can metabolize filler faster than more static zones such as the cheeks.

To prolong the effects, it’s recommended that patients schedule regular touch-ups every six or so months. 

Are HA Fillers Right for You?

If you’re in good overall health, have realistic expectations, and prefer a treatment with little to no downtime, hyaluronic acid fillers can be an excellent choice. These treatments are a safe, effective, and minimally invasive way to rejuvenate your appearance. With the guidance of an experienced provider, you can design a personalised plan that aligns with your goals and helps you look refreshed and confident at any age.
