Facial fillers have become one of the most popular ways to refresh, rejuvenate, and subtly enhance your appearance without surgery. But with so many types of fillers available — and just as many providers offering them — it’s important to know not only what you’re having, but who is carrying out your treatment.

At Cosmedicare St. Ellen’s Hospitals, our goal is to educate, inform, and empower you to make the right choices for your face, your lifestyle, and your safety.

Types of Facial Filler

Not all fillers are the same. Different products are designed for different areas and effects:

1.  Hyaluronic Acid (HA) Fillers

The most commonly used type. Hyaluronic acid is a natural substance found in the skin that attracts and holds water.

• Best for: Lips, cheeks, tear troughs, jawline, chin, and fine lines.
• Benefits: Natural-looking, versatile, reversible, hydrating.
• Longevity: Usually 6–18 months depending on the product and area.

2.  Collagen-Stimulating Fillers (e.g. Radiesse®, Sculptra®)

These fillers don’t just add volume — they stimulate your body’s own collagen production for gradual, long-lasting results.

• Best for: Deeper lines, midface rejuvenation, overall facial volume loss.
• Benefits: Longer-lasting improvement in skin thickness and firmness.
• Longevity: Up to 2 years.

3.  Calcium Hydroxylapatite Fillers

A mineral-like compound naturally found in bones, used in a smooth gel form.

• Best for: Deeper folds (nasolabial, marionette lines), contouring cheeks and jawline.
• Benefits: Provides immediate lift plus collagen stimulation.
• Longevity: Around 12–18 months.

4.  Polylactic Acid Fillers

A biocompatible substance that stimulates collagen over time.

• Best for: General facial rejuvenation, volume restoration.
• Benefits: Gradual, natural-looking improvement.
• Longevity: Often up to 2 years with a course of treatments.

How Do You Know Which Filler is Right for You?

That depends on:

• The area being treated.
• The result you’re looking for (subtle vs structural).
• Your budget and how long you’d like results to last.
• Your medical history and suitability.

And this is exactly why choosing the right injector is just as important as choosing the filler.

Why the Right Injector Matters

At Cosmedicare, all filler treatments are carried out by HIS-registered hospital-based, specialist nurse prescribers. That means:

• You’re in the hands of a regulated professional, accountable to the Nursing & Midwifery Council (NMC).
• Your injector understands anatomy, safety, and complication management.
• You’ll receive an individual consultation, exploring all filler options and whether they’re right for you.
• We only use premium, evidence-based products — and we’ll always be transparent about what’s being used.

The wrong injector can leave you with poor results, inappropriate product placement, or worse — serious complications. The right injector, on the other hand, gives you:

• Safe, medically-led care
• Honest advice
• Natural, tailored results

The Bottom Line

Facial fillers are not “one size fits all.” The best outcomes come from a combination of the right product and the right injector.

• Hyaluronic acid fillers for hydration and contour.
• Collagen-stimulating fillers for longer-term rejuvenation.
• Specialist nurse prescribers for safe, effective, and bespoke results.
