How Do Facial Fillers Work?
Facial fillers are injectable substances used to restore volume, smooth wrinkles, and enhance contours. They are made from materials like hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid and gradually integrate with your skin tissues.
What Happens to Fillers Over Time?
Facial fillers naturally break down and are absorbed by the body. The process depends on the type of filler and individual factors such as metabolism and treatment area.
- Hyaluronic Acid (HA) Fillers: Dissolve naturally in 6–18 months through enzymatic activity in the body.
- Calcium Hydroxylapatite (Radiesse): Breaks down over 12–18 months while stimulating collagen production.
- Poly-L-lactic Acid (Sculptra): Stimulates collagen and gradually disappears over 2–3 years.
- Polymethyl Methacrylate (PMMA) – Bellafill: Semi-permanent and remains in the skin for up to 5 years.
Visible Changes Over Time
As fillers degrade, you may notice:
- Reduced Volume: The treated area gradually loses fullness as the filler dissolves.
- Natural Integration: Fillers blend with tissues, maintaining a natural look even as they diminish.
- Collagen Stimulation: Some fillers, like Sculptra, leave behind enhanced collagen for prolonged effects.
Do Fillers Leave Residue?
FDA-approved fillers typically dissolve completely without leaving harmful residue. However, overuse or improper injection techniques may cause minor changes like scar tissue or skin laxity.
How to Maintain Filler Results
- Schedule Maintenance: Regular touch-ups keep results consistent.
- Protect Your Skin: Use sunscreen to prevent premature aging.
- Stay Hydrated: Supports hyaluronic acid fillers’ plumping effects.
- Choose Skilled Providers: Proper injection techniques enhance filler longevity.
Conclusion
Over time, facial fillers naturally break down and are absorbed by the body, with results diminishing gradually. Regular maintenance and proper care can help preserve the aesthetic benefits and ensure safe, effective outcomes.
