If you’ve started to notice your cheeks looking flatter, a shadow settling under your eyes, or deeper lines running from your nose to your mouth, you’ve probably wondered whether dermal fillers are the answer. Fillers are one of the most common treatments we perform, and also one of the most misunderstood. This guide covers what they are, where they’re used, how long they last, and what the appointment is actually like, so you can walk into a consultation knowing what to ask.
What Dermal Fillers Are (and What They Aren’t)
Dermal fillers are injectable gels placed beneath the skin to restore volume, define contours, and soften folds. They are different from Botox and Dysport, which relax the muscles that cause expression lines. Neuromodulators address movement; fillers address structure. Many patients benefit from both, but they do different jobs.
Most fillers used today are made from hyaluronic acid (HA), a sugar molecule your skin already produces to hold moisture. At Devenir, our HA options include the Juvederm collection (Voluma, Vollure, Volbella, Ultra Plus) and the Restylane collection (Lyft, Defyne, Refyne, Kysse). Each product has a different thickness and flexibility, which is why a firmer gel might be chosen for the cheekbone while a softer one is used in the lips.
There is also a second category, biostimulatory fillers, which work differently. Sculptra (poly-L-lactic acid) gradually encourages your own collagen production over three to six months, and Radiesse (calcium hydroxylapatite) is often used in structural areas like the jawline and hands. These build results more gradually and behave differently from HA fillers in one important way, covered below.
Why Reversibility Matters: Hylenex
One of the most useful things to know about hyaluronic acid fillers is that they can be dissolved. If a result isn’t what you wanted, or if an adjustment is needed, an enzyme called hyaluronidase (Hylenex) can break down HA filler. That gives patients a safety net that other filler types don’t offer.
Sculptra and Radiesse are not reversible in the same way, though they do gradually metabolize over time. This is one reason first-time filler patients are often started with an HA product, and why it’s worth asking your provider which type they’re recommending and why.
Common Treatment Areas
Filler is rarely about adding volume for its own sake. The goal is to replace what has been lost with age and to bring the face back into proportion. The most commonly treated areas include:
- Cheeks: restoring mid-face volume and lift, which can also soften the look of the lower face.
- Under-eyes (tear troughs): softening the hollow that creates a tired-looking shadow.
- Nasolabial folds: smoothing the creases that run from the nose to the corners of the mouth.
- Marionette lines: addressing downturned corners of the mouth.
- Lips: adding volume, definition, or symmetry.
- Jawline and chin: sharpening the jaw and projecting the chin for a more defined profile.
- Temples: restoring hollowness in the upper face.
Lips deserve a special mention because the approach there is deliberately conservative. First-time lip filler patients typically receive 0.5 to 1 mL, and results are assessed at two weeks before deciding whether to add more. You can always add at a follow-up, but you can’t take product away without dissolving it.
For patients with several concerns at once, treating one area in isolation can sometimes look unbalanced. Facial balancing looks at the face in thirds (upper, middle, and lower) and combines filler with neuromodulators to create harmony across the whole face rather than correcting one feature at a time.
How Long Do Fillers Last?
Longevity depends on the product and the area treated, along with individual factors like metabolism. As a general guide:
- Lip filler typically lasts around 9 to 12 months.
- Cheek and jawline filler can last 12 to 18 months or longer.
- Sculptra results build gradually and can last two years or more.
Areas with more movement, like the lips, tend to break down filler sooner than more static areas like the cheekbones. Your provider will discuss expected longevity for the specific products in your plan.
What to Expect at Your Appointment
A filler appointment usually takes 30 to 60 minutes. It begins with an assessment of your face, including where volume has been lost and how your features relate to one another, before any product is chosen.
A topical numbing cream is applied first, and most fillers also contain lidocaine, a local anesthetic mixed into the gel, so discomfort during injection is generally minimal. The lips are more sensitive than other areas, but the treatment itself is quick.
Results are visible right away, with the final result settling in at about two weeks as any swelling resolves. That two-week mark is when your provider can evaluate the outcome and decide whether any refinement is needed.
Downtime and Aftercare
Downtime is usually minimal. Mild swelling and bruising are normal for one to three days, and lips in particular can look larger than the final result during the first 24 to 72 hours. Ice can help. For lip filler, we recommend avoiding strenuous exercise, alcohol, and extreme heat for the first 24 hours. As with any injectable, there are risks, and your provider will review them with you along with the pre- and post-treatment instructions for your specific treatment.
Is Filler Right for You?
Filler tends to be a good fit if your main concern is lost volume, hollowness, or folds that are visible whether or not your face is moving. If your concern is mainly lines that appear when you make expressions, a neuromodulator may be the better starting point, and many plans use both. The most reliable way to know is an in-person assessment, since the right product and placement depend entirely on your anatomy and goals.
