Dermal Fillers

Dermal fillers are injections that are used to provide volume and fullness to the face. They can enhance shallow contours, plump thin lips, soften facial wrinkles or creases, and improve recessed scar appearance.

The effect of treatment varies depending on the type of material used as a filler:

  • Collagen: 3-4 months.
  • Hyaluronic acid: 4-6 months
  • Calcium hydroxylapatite: 18 months
  • Poly-L-lactic acid (PLLA): The injections are given over several months with the effect lasting up to two years
  • Polymethylmethacrylate beads (PMMA): permanent effect, but most risky.

Recovery time

There is zero downtime after undergoing a dermal filler injection. In most cases, you should be able to return to your activities of daily living right away.


A local anesthetic cream may be offered for comfort. Using several small injections, the dermal filler is placed at the desired locations for maximum aesthetic effect.

Immediately after the injection, the treated area may appear overfilled with mild bruising or swelling. There may also be some transient redness and numbness. These symptoms may be alleviated within a couple of hours or a few days using topical ice application.


You are advised to avoid alcohol, coffee, or direct sunlight exposure for 24 hours after the injection.


There is a small risk of developing a rash, swelling, bruising, infection, and formation of lumps under the skin for which you should return to the clinic.
