Dermal Fillers 101 with Dr Sabika

By Dr Sabika Karim 28 February 2025

Why I am talking about Dermal Fillers today… I have always believed natural looking treatments and being the very best version of you, because looking good, is feeling good. There are many different treatments available in our aesthetic doctor toolkit, but one of the most frequently requested treatments or concerns are related to HA dermal fillers, Also known as HA (Hyaluronic Acid) Fillers, Facial Fillers, Dermal Fillers and despite HA fillers being a well studied, established treatment, there is a lot of misinformation on the web and social media especially, so I wanted to take the time to explain what dermal fillers actually are, how they work, and what to expect. As always if you have any questions about these treatments or want to talk to us directly at Skin Medical, you can easily do so by email, phone or website form.

What Are HA Dermal Fillers and How Do They Work?

Dermal fillers are injectable gel-like substances used to restore lost volume, smooth wrinkles, and enhance facial contours. Most modern fillers are made from hyaluronic acid (HA) also known as face and lip fillers, are non-invasive injectable treatments designed to smooth fine lines and restore lost volume in key areas such as the lips, cheeks, nose, jaw, and temples.

As we age, our collagen, elastin, and HA levels decline, leading to a loss of skin structure and firmness. Fillers work by replenishing these lost components, creating a plumper, smoother, and more youthful appearance. Many people still confuse Fillers with the brand name Botox, which works by relaxing muscles to reduce wrinkles, fillers physically add volume to sculpt, fill or reshape the face.

Are HA Fillers Safe?

At Skin Medical, safety is our top priority. Given the minimal regulation of dermal fillers in the UK, it’s crucial to choose an experienced medical professional like Dr Sabika Karim or Dr Saif Abbas Chatoo who lead these treatments with precision and expertise, tailoring each procedure to your unique facial structure and aesthetic goals.

Whilst HA fillers are considered safe in the right hands, there are common side effects include mild swelling, bruising, or redness. Hyaluronic acid fillers can also be dissolved if necessary, making them a safe and flexible option.

Understanding the treatment process can help potential patients make a more informed decision and plan your visit. This all starts with a consultation, this includes a full face assessment to discuss your concerns and treatment options. If you wish to go ahead with the treatment a topical numbing cream is applied for comfort, the HA fillers are then carefully placed using a fine needle or in some cases a cannula. Following the treatment you will be given clear advice on how to care for your skin and treatment areas in the days following the procedure.
