What are hyaluronic acid fillers?
If you’re considering having a hyaluronic acid filler, it’s important to be well-informed about the treatment, how it works, and the possible risks. Hyaluronic acid fillers are a popular choice for people looking to rejuvenate their face, reduce wrinkles, or enhance the volume of areas such as the lips, cheeks, or chin. In this article, we cover everything you need to know—from the basics of hyaluronic acid to choosing the right practitioner and aftercare following treatment.

What Is a Hyaluronic Acid Filler?
A hyaluronic acid filler is a clear gel injected in small amounts into the skin. Its purpose is to improve the shape and structure of the face by adding volume or smoothing out wrinkles. The gel contains hyaluronic acid, a substance naturally found in the body that helps retain moisture. Popular brands of hyaluronic acid fillers include Restylane®, Juvederm®, Belotero®, and Emervel®.
What Are Hyaluronic Acid Fillers Used For?
Hyaluronic acid fillers can be used for various purposes, depending on your goals and the areas you want to treat. They are commonly used to:
Reduce wrinkles: Such as laugh lines, marionette lines, frown lines, forehead wrinkles, and crow’s feet.
Add volume: For example, fuller lips, enhanced cheeks, or a more defined jawline.
Improve skin texture: In some cases, filling certain areas can make the skin firmer and smoother.
What Is Hyaluronic Acid?
Hyaluronic acid is a substance naturally produced by the body. It has the unique ability to bind large amounts of water—up to 6 litres per gram. For example, the vitreous body in the eye consists of around 98% water and just 2% hyaluronic acid.
Because water is almost incompressible, tissues rich in hyaluronic acid are also resilient, particularly in connective tissue. This helps protect structures like intervertebral discs from damage. Normally, body weight—and activities like running or jumping—would place too much stress on these areas, potentially causing harm. Hyaluronic acid, as a component of synovial fluid in joints, acts as both a lubricant and a cushion.
Hyaluronic acid fillers are crosslinked. The degree of crosslinking varies by brand and type, determining how firm, durable, and water-binding the filler is. The purity of the hyaluronic acid and its level of crosslinking largely determine the quality of the filler.

What Can You Do with Hyaluronic Acid Fillers?
Hyaluronic acid fillers are primarily used to smooth wrinkles, restore volume to sagging skin, and enhance facial contours. For example, they can define the lip line, create symmetrical cheekbones, or fill tear troughs.
As you age, the skin loses volume and firmness, making fine lines more visible and causing slight sagging. By injecting a small amount of hyaluronic acid with a fine needle into areas of volume loss, you can restore structure and firmness. Common areas include the cheekbones, under the eyes, nasolabial folds, and the lips.

When Should You Avoid Hyaluronic Acid Fillers?
There are certain situations in which it’s better not to undergo a hyaluronic acid filler treatment:
If you have ever had an allergic reaction to hyaluronic acid or a filler.
If you are pregnant or breastfeeding.
If there is already a permanent filler in the area to be treated.
If you have an active herpes simplex infection (such as a cold sore), as this could worsen the condition.
If you have a skin infection or other active skin issues in the area to be treated.
What Does a Hyaluronic Acid Treatment Involve?
A hyaluronic acid treatment is usually quick and effective. Here’s what to expect:
Numbing: Depending on the area being treated, you can choose a numbing cream, ice, or a local injection to temporarily numb the area.
The Treatment: The filler is injected into the skin using a fine needle, one injection at a time. This usually takes 15–30 minutes, depending on the size of the treatment area.
After the Treatment: The treated area is gently massaged to ensure the gel is evenly distributed.

What Results Can You Expect from a Filler Treatment?
The results of a hyaluronic acid treatment are visible immediately, but the effects are not permanent. Hyaluronic acid is gradually broken down by the body. Results typically last between 6 and 12 months, but with a follow-up treatment, they can last up to 18 months. For areas like the lips, top-ups every 6 months are often recommended to maintain optimal results.

What Are the Possible Side Effects of Hyaluronic Acid Fillers?
Although hyaluronic acid treatments are generally considered safe, some side effects can occur. The most common include:
Redness, swelling or bruising: These usually settle within a few days to a week.
Unevenness or small lumps: Sometimes the filler doesn’t spread evenly, which can often be corrected with gentle massage.
Rare complications: In very rare cases, a blockage can occur if filler enters a blood vessel. This carries a small risk of vision problems, particularly with frown line treatments.
What Can and Can’t You Do After the Treatment?
After your treatment, there are a few important things to keep in mind:
You can:
Wash your face as normal and apply makeup.
Use a cold compress to ease swelling or tenderness.
You should avoid:
Intense physical activity such as exercise for 24–48 hours.
Saunas, sunbeds, or prolonged sun exposure for one week after treatment.
Laser treatments or chemical peels in the weeks following treatment, as these can trigger inflammation.
When Should You Contact Your Practitioner?
It’s important to get in touch with your practitioner if any side effects don’t settle within a few days, or if you experience severe swelling, pain, or unusual symptoms. Always seek advice if you’re concerned about your treatment.
Experiences
I had an excellent experience at Therapie Clinic Bishopsgate and I truly recommend this clinic.
I’ve been going there for laser hair removal and I’m extremely impressed with both the technology they use and the results. In my opinion, it’s the best laser hair removal treatment I’ve ever tried. Everything is done very professionally and the procedures are always clearly explained beforehand.
I also had lip fillers with hyaluronic acid, and the result is absolutely beautiful. My lips have never looked this good — the shape is perfect and very natural.
The Botox treatment was also excellent, giving a very natural and refreshed look.
A special mention goes to Dr Wei Sheng L., who is a wonderful doctor — extremely professional, attentive to detail, and very reassuring. He takes the time to explain everything and makes you feel comfortable and safe throughout the treatment.
The staff are also incredibly kind and welcoming, and the overall atmosphere of the clinic is very professional.
I will definitely continue coming here and highly recommend this clinic to anyone looking for high-quality aesthetic treatments in London. ✨💉 Show less »
I was concerned about my hair thinning in some areas and showing patches, so I did some research and found the clinic and doctor Fahad who recommended PRP treatment and clearly explained the procedure. After 5 sessions of PRP treatment I can see that the hair is now growing and I love the way it that looks now.
Dr Fahad is clearly knowledgeable and skilled, with a warm manner and took the time to discuss my case in detail which gave me reassurance.
I also had Profhilo hyaluronic acid moisturising treatment on my face for hydration and plumping and helping to create a radiant and rejuvenating effect. I am so pleased with the results that I will be going back again soon for another treatment.
Everyone I dealt with at the clinic was helpful and welcoming.
I highly recommend Dr Fahad and the clinic. Show less »
After significant weight loss over several years, I became self-conscious about the lack of volume in my gluteal area and did not have sufficient body fat for a traditional BBL. In an effort to improve these concerns, I underwent multiple surgeries—including abdominoplasty, thigh lift, bilateral Pitanguay excision, posterior body lift, and buttock implants. Unfortunately, the implants contributed to hip dips and visible outlines, and my limited adipose tissue made further solutions challenging.
My journey took me from the United States to Dr. Ducu’s clinic following unsuccessful attempts with liquid BBLs using hyaluronic acid filler, which did not yield lasting results. I also pursued several rounds of Sculptra treatments without satisfactory outcomes. Choosing the DBL™ procedure at this clinic proved to be the optimal decision; I am now highly pleased with the aesthetic improvement of my gluteal region. In retrospect, visiting this clinic initially would have saved both time and financial resources.
The procedure was virtually painless with minimal bruising, especially compared to previous treatments, and I was able to return home the next day.
For anyone considering a DBL™, I highly recommend Dr. Bisma. I intend to return for a touch-up in approximately eight months. Show less »

I had Plasma face, Pure Hyaluronic Acid, and Glutathione treatments with Dr Mohammad, and I’m very happy with the results.
Thank you so much and good luck. Show less »
I’ve now been to her three times, and each visit has been just as professional, caring, and friendly as the last. During treatments, she’s so gentle and attentive, always checking that I’m comfortable. And the support doesn’t stop when I leave , she’s always happy to answer any questions, give advice on products, and guide me on how to keep my results looking their best.
She also kept me well informed about which products are cruelty-free, which is something that’s very important to me, and I really appreciated that extra thought and understanding.
It’s rare to find someone who combines such skill, attention to detail, and genuine care for their patients. I feel completely confident in her hands and so grateful to have found her ahead of my big day. If you’re considering aesthetic treatments, I can’t recommend Dr C highly enough. Show less »
Dr Kate was warm, friendly and professional with a great 'bedside manner' she was a former GP after all! And I wanted someone that had medical knowledge. She made me feel very relaxed and reassured. She talked me through the procedure amd I was able to ask any questions. There wasn't a conveyer belt of clients and Dr Kate took her time, I didn't feel rushed.
The clinic is discreet, clean and the receptionist Elena is lovely, making you feel welcome.
For a first experience I can't rate Dr Kate Aesthetics enough to be honest. Being a 'first-timer' I was a bit anxious that evening about my lips so I messaged Dr Kate who messaged back and video called me the next morning. She was not concerned, offered me reassurance and put my mind at rest.
I am already looking at booking in for another procedure with Dr Kate! Show less »
I also had the CV Aesthetics lip treatment as my lips , especially the bottom one was dry and scabby from biting my lip . I had lip coconut lip scrub , AHA exfoliator , cherry Hyaluronic Acid lip mask then finished with Lip Conditioner . My lips were instantly hydrated , smoother and much plumper . I would definitely recommend Claud and these treatments . Thanks x Show less »
Claire was fantastic and so helpful. She really put me at ease through the treatment and we had a lovely chat about all things skin!
After my facial I asked for any products she would recommend based on what I was currently using, what results I wanted to see and what may be missing from my routine. Claire wasn’t pushy unlike some clinics can be, and suggested a Hyaluronic Acid serum as I’d not used one for a while.
I was really happy with my overall experience, the treatment and advice received and will definitely book back for more. Thank you so much team Haywards! Show less »

Frequently asked questions about hyaluronic acid fillers
What is a hyaluronic acid filler?
A hyaluronic acid filler restores volume where the skin needs it most. As we age, the skin naturally becomes thinner. A hyaluronic acid filler works by hydrating the skin from within while adding the desired volume for a fresher, more youthful look.
What does a hyaluronic acid filler do?
Hyaluronic acid is a substance that naturally occurs in the body and acts as a powerful water binder. Pure hyaluronic acid can hold up to 1,000 times its own weight in water, making it highly effective at keeping the skin hydrated from within. In addition to its moisturising properties, it also restores volume to the skin, helping to smooth out fine lines and wrinkles. The result is a fresher, fuller, and more youthful appearance.
How long does a hyaluronic acid filler last?
A hyaluronic acid filler typically lasts around 9 months. A firmer type of filler often provides longer-lasting results, while a softer filler (for example, used in the dynamic lip area) usually has a shorter effect. Compare different hyaluronic acid fillers on Injectablesbooking.
What is the difference between hyaluronic acid fillers and Radiesse?
Radiesse stimulates your body’s own production of collagen and elastin. This creates natural volume and improves skin firmness. In contrast, regular fillers contain hyaluronic acid, a substance that attracts moisture and provides additional volume.
What is the difference between Profhilo and hyaluronic acid fillers?
Fillers soften lines and folds while restoring lost volume in the face. However, they do little to improve overall skin quality. Profhilo, on the other hand, directly targets skin quality: it strengthens the skin from within, reduces skin laxity, and gives a healthy, natural glow.
