Ask A Doctor: All You Need to Know About Dermal Fillers

Dermal Filler's Advice from Dermatology Expert Dr Jonathan Nevin Yu - Effortless HA Filler

What should you look out for when considering dermal fillers? Does it give you an overfilled look?

As the landscape of non-surgical cosmetic enhancements evolves, dermal fillers have emerged at the forefront, promising an effective pathway to youthful rejuvenation. Nevertheless, an informed approach is vital while considering this treatment, including understanding potential outcomes such as the often-discussed 'overfilled look.'

According to Dr. Jonathan Nevin Yu, a board-certified dermatologist and aesthetic treatment expert at JY Dermatology and Aesthetic Center, modern dermal fillers deliver natural-looking results. However, to achieve the best outcomes, there are a few critical factors one must consider.

Understanding Dermal Fillers

Dermal fillers, as their name suggests, fill the space under the skin with a gel-like substance, smoothing out wrinkled areas and restoring volume.

Among the most popular dermal fillers used are Hyaluronic Acid (HA) fillers and Calcium Hydroxylapatite (CaHA) fillers, known for their adaptability and versatility in addressing various aesthetic concerns.

According to Dr. Yu, the most common treatment area has been the region around the eyes.

First-Time Patients

As a first-time patient, you may have many questions and apprehensions.

Dr. Yu's advice is to come in for the first session without any makeup to allow the dermatologist to make a comprehensive examination of your skin.

The initial consultation is crucial as it enables the professional to understand your needs and expectations, subsequently guiding you towards treatments that best align with your goals.

So, go in with an open mind and be ready to ask questions.

Downtime and Duration

The downtime associated with dermal fillers is generally minimal. While some patients might experience mild bruising, particularly in sensitive areas like the lips and chin, this usually dissipates quickly.

As for how long the effects of dermal fillers last, it depends on the type of filler and the treatment area. CaHA fillers can last up to 18-24 months, while lip treatments with HA fillers typically last around 8-10 months.

Complementary Treatments

Once you've had fillers, you might be keen on exploring other treatments.

Depending on your recovery process, you could resume other treatments such as facials and laser therapy as soon as two weeks post-filler injections .

Combination treatments, according to Dr. Yu, can enhance the overall results.

A treatment regimen could start with a procedure like micro-focused ultrasound with visualisation (MFU-V) to tighten the skin, followed by dermal fillers in areas needing volume, and then botulinum toxin to address dynamic lines.

Overcoming Filler Myths

A common concern among patients is the "overfilled look," a phenomenon Dr. Yu calls the "facial overfilled syndrome ." This can be easily avoided with the right technique and an accurate assessment of the number of syringes required for a refreshed look.

Dispelling other common myths, Dr. Yu assures that with modern techniques and high-quality products, dermal fillers are not painful, risky, or responsible for a weighed-down, unnatural appearance.


In conclusion, dermal fillers are a promising avenue for aesthetic enhancement, provided you approach them with the right mindset and guidance.
