Everything You Need To Know About Dermal Fillers — From The Experts

It’s perfectly normal to want to slow down or reverse the signs of ageing. As we age, we start to focus on all the lines and wrinkles appearing on our face. Getting dermal fillers is not a taboo subject to discuss anymore. Celebrities are open about how they seem never to age, and everyday people are turning to clinics like ours to see what these fillers are all about.

Women and men of all ages are turning to non-surgical treatments like Botox and dermal fillers because they are more affordable, safer, and easier to endure than their surgical counterparts. There’s also little to no downtime and recovery. It’s a win/win. Non-surgical procedures do not require surgery or a trip to the hospital, and can even be done on your lunch break. Today we answer all your questions about dermal fillers, how long do they last, are they safe, what are the side effects of using fillers, and more.   

What Are Dermal Fillers Made From? 

Dermal fillers are made from pharmaceutical grade hyaluronic acid (HA), a gel-like substance similar to the naturally occurring hyaluronic acid found in your body. Hyaluronic acid attracts water molecules, which helps keep the body and skin hydrated. In our youth, we produce HA in abundance. Unfortunately, as we get older, HA production slows, leading to a decrease in elasticity in our skin. Since HA has this ability to moisturise and plump the skin, many younger women under thirty are using fillers as a way to stave off wrinkles before they appear. 

We use dermal fillers to “fill” lines, wrinkles, gaps, shallowness, and imperfections in the face, hands, and body, as well as bring moisture, plumpness and more elasticity all over. The most common area that people use fillers on is the face and we discuss each of those below. The most popular fillers used in cosmetic clinics are Restylane and Juvéderm, and each brand has different types of fillers for different parts of the face.

What Kind of Face Fillers Treatments Are Available?

If you’ve been thinking about reducing the signs of ageing on your face, you have many choices when it comes to facial fillers. There are several popular areas around the face where people get hyaluronic acid fillers, and we’ll share with you our most popular below.

Everyone wants to have pouty, Kylie Jenner lips and people of all ages and genders are getting their lips plumped. Lips filler will generally last between four and eight months; then you’ll need to come into the clinic for a “top-up”. Certain fillers are best for the lips, so you want to visit a well-trusted clinic for lip fillers. The lips are one area of the face where it would be disastrous if the procedure were botched. Thankfully the right filler is dissolvable if you get too much. Remember, less is more when it comes to the lips — we suggest going for subtle — you can always get more the next time if needed.

Tear Troughs

One of the best-selling treatments we offer is tear trough filler. We target the area under the eyes where you could have dark circles, sunkenness, and a loss of elasticity. If you have bags or dark circles under your eyes, this dermal filler will help reduce these problems by lifting and filling out the area. After numbing the area, we carefully introduce the filler into the tear trough through a fine injection needle. Then the filler is gently massaged into the tear trough and blended around the cheekbone to create a smooth, firm foundation for your under-eye area.

Smile Lines

If you notice that lines have formed around your mouth, this is a good thing. That means you’ve been smiling and laughing a lot during your life! But as we age, these lines get deeper and more pronounced while we aren’t smiling. Or maybe you have fine lines forming on your upper lip that make you feel self-conscious. This is where dermal fillers step in. We can plump up and soften the nasolabial folds around your mouth with our smile line filler treatment.  


Have you ever been jealous of someone with perfect cheekbones or nice plump cheeks? Today you can have that look with dermal fillers! Cheeks fillers are one of our easiest and quickest dermal filler procedures. As with other treatments, the filler is injected with a small needle and massaged around the area to get the desired look. 

We can also use fillers to fix a crooked nose or give you a more pronounced or thinner jawline, but the procedures above are the most popular in our London clinic. 

What’s the Difference between Dermal Fillers and Botox

Dermal fillers generally bring moisture and build elasticity to plump an area. Botox, on the other hand, is botulinum toxins that restrict movement in targeted areas to eliminate wrinkles. All the treatments above use dermal fillers, while Botox is not always suitable for every area of the face. A professional clinic will know the best course of action for your goals and needs. They may suggest one or the other, or a combination of fillers and Botox to achieve your desired look. The goal with Botox and fillers is to make you look as natural as possible, so no one will even notice you’ve had the procedure. Botox is typically used on fine lines around your eyes and mouth or to help deep wrinkles around your forehead disappear.

Are Dermal Fillers Safe?

Since hyaluronic acid is FDA and EU-approved to use for face fillers and is already in the body, it is considered safe. All of our treatments are government-approved, safe and used with thousands of clients each year. It’s good to mention here that fillers are reversible, unlike Botox, so if you aren’t feeling good about the procedure, you have a way back. HA-based fillers can be dissolved using Hyaluronidase, giving you a safety net and extra peace of mind should you decide to get fillers. Hyaluronic acid fillers are broken down naturally by the body within twelve months. Because of this, there is no evidence that long-term use of fillers is damaging or life-threatening. 

Does It Hurt to Have Facial Fillers?

Although getting dermal fillers is a quick and relatively painless procedure, many people who feel uncomfortable with needles may want to take extra precautions. Our dermal filler treatments use small needles for a less painful process. We do everything we can to make sure you are comfortable and relaxed. We can use a numbing cream for clients who have a lower pain tolerance. An ice pack might help minimise bruising after the treatment. There is virtually no recovery process.

How Long Do Dermal Fillers Last?

If you are thinking about getting dermal fillers, it’s good to know they can last nine to twelve months or even up to two years for some, depending on factors like age, lifestyle and heredity, and the type of dermal filler used. Everyone will react differently to the treatment, but most people only need to top-up their fillers once a year. We should also mention your wrinkles will not instantly disappear after treatment — it may take up to two weeks to see the final results, so be patient. 

How Much Do Dermal Fillers Cost?

We aren’t going to lie — dermal fillers and Botox are not cheap. But the good news is that they often don’t need topping up for a year or more so it’s worth the price to get the ageless beauty you deserve.
