The face starts to lack volume and appears aged with deeper nasolabial folds, unaesthetic lines, a deeper fold, the lips start to thin, and turning down the corners of the lips. Hyaluronic acid fillers are injected right underneath these folds to replace the volume lost which creates a younger look in the face by replenishing your body's natural production of hyaluronic acid, which diminishes as you age.

Which types of fillers are available?

There are various types of fillers:

  • Hyaluronic acid

Hyaluronic acid is a naturally occurring substance that is already found in your skin.

It helps keep skin plump and hydrated.

HA fillers are typically soft and gel-like.

The results are temporary, lasting 6 to 12 months or longer before the body gradually and naturally absorbs the particles.

Most HA fillers are infused with lidocaine to help minimize discomfort during and after treatment.

FDA approved hyaluronic acid brand name fillers include:

  • Captique
  • Esthélis
  • Elevess
  • Hylaform
  • Juvederm
  • Perlane
  • Prevelle
  • Puragen
  • Restylane

As we covered, the most common type of facial filler is hyaluronic acid – the natural substance found in many areas of the body including joints and skin.

  • Calcium Hydroxylapatite (CaHA)

Calcium hydroxylapatite is also a naturally occurring substance, found primarily in our bones.

Is one of the most well-studied dermal fillers worldwide and has been extensively used for the correction of moderate-to-severe facial lines and folds and to replenish lost volume.

When used in a filler, the calcium particles are nearly microscopic and suspended in a smooth gel.

Calcium hydroxylapatite is also reported to help stimulate natural collagen production, and it is typically used for deeper lines and wrinkles.

FDA approved CaHA fillers include Radiesse.

  • Polymethylmethacrylate (PMMA)

PMMA is a synthetic, biocompatible substance that has been used in medicine for much of the last century.

PMMA fillers contain collagen, a naturally occurring substance in the skin that provides structure and firmness.

FDA approved PMMA fillers include Bellafill® (formerly known as Artefill).

  • Poly-Caprolactone (PCl)

Poly-L-lactic acid is a biocompatible, biodegradable synthetic substance.

Its products are technically classified as “collagen stimulators,” as their main mechanism to smooth fine lines is by helping your skin rebuild natural collagen—the filler gel itself dissipates a few days after treatment.

Poly-L-lactic acid is typically used to treat deeper facial wrinkles, and results can last more than 2 years.

FDA approved Poly-L-lactic acid fillers include Sculptra Aesthetic.
