Dermal Filler FAQ (Frequently Asked Questions)

Published: September 18, 2025

1. What are dermal fillers?

Dermal fillers are injectable gels used to restore lost volume, smooth wrinkles, and enhance facial contours. Most are made of hyaluronic acid (HA), a substance naturally found in the skin.


2. What do fillers treat?

Fillers can address:

  • Nasolabial folds (smile/laugh lines)
  • Marionette lines
  • Cheek volume loss
  • Lips (enhancement or definition)
  • Tear troughs (under-eye hollows)
  • Jawline contouring
  • Chin enhancement
  • Temples
  • Hands (rejuvenation)
  • Scarring (e.g. acne scars)

3. How long do fillers last?

It depends on the product and treatment area:

  • 6–12 months for most HA fillers (like Juvederm, Restylane)
  • 12–24 months for thicker fillers (like Voluma or Radiesse)
  • Non-HA fillers like Sculptra or Radiesse may stimulate collagen and last longer

4. Are dermal fillers safe?

Yes—when administered by a trained, qualified injector. Most side effects are mild and temporary (e.g. swelling, bruising). Serious complications are rare but can include vascular occlusion (blocked blood flow), which requires prompt treatment.


5. Do fillers hurt?

Mild discomfort is possible, but most fillers contain lidocaine, a local anesthetic. Topical numbing or ice can also be used for sensitive areas like lips.


6. When will I see results?

  • Immediately after injection, though swelling may temporarily affect appearance.
  • Final results settle in 1–2 weeks.

7. What’s the difference between fillers and Botox?

  • Fillers add volume and shape.
  • Botox relaxes muscles to reduce dynamic wrinkles (like frown lines).They are often combined for full facial rejuvenation.

8. Are fillers reversible?

Only hyaluronic acid (HA) fillers are reversible with hyaluronidase, an enzyme that dissolves the filler. Non-HA fillers (like Sculptra or Radiesse) are not reversible.


9. How do I know which filler I need?

That depends on:

  • Treatment area
  • Desired result (hydration vs. structure)
  • Skin type and ageA qualified injector will assess and choose the right product (e.g. a softer filler for lips, firmer one for jawline).

10. What are the side effects of dermal fillers?

Common (temporary):

  • Redness
  • Swelling
  • Bruising
  • Tenderness
  • Lumps (usually resolve or can be massaged)

Rare but serious:

  • Vascular occlusion (blocked artery)
  • Infection
  • Nodules or granulomas
  • Tyndall effect (bluish tint if filler is too superficial)

11. Can fillers make you look unnatural?

They can—if overdone or poorly placed. Natural results come from conservative, well-planned treatments by experienced injectors who understand facial anatomy and aesthetics.


12. How should I prepare for a filler appointment?

  • Avoid blood thinners (aspirin, ibuprofen, fish oil) 3–5 days before
  • Avoid alcohol 24 hours prior
  • Arrive makeup-free
  • Plan ahead: bruising/swelling may last a few days

13. What should I avoid after treatment?

  • Touching/massaging the area (unless instructed)
  • Strenuous exercise for 24 hours
  • Alcohol, heat (saunas), and makeup for 24–48 hours
  • Dental work or facial massages for 2 weeks (in some cases)
