Calcium Hydroxyapatite and Poly-L-Lactic Acidin Hertfordshire.

Calcium Hydroxyapatite (CaHA) and Poly-L-Lactic Acid (PLLA) are both popular dermal fillers, each with unique characteristics. Here’s a breakdown of their differences in terms of composition, action, applications, techniques, and side effects.

• CaHA: Contains microspheres of calcium hydroxylapatite, a mineral found in bones and teeth, suspended in a gel carrier made of water, glycerin, and carboxymethylcellulose.
• PLLA: A synthetic, biodegradable polymer derived from lactic acid. It comes as a powder that is mixed with sterile water before injection.

• CaHA:
  • Provides immediate volume and structural support after injection.
  • The gel carrier adds initial volume, while the calcium microspheres stimulate collagen production over time.
  • Results last up to 12-18 months.
• PLLA:
  • Stimulates the body’s natural collagen production, not providing immediate volume.
  • As PLLA particles dissolve, collagen gradually replaces them, leading to a slow increase in skin volume and thickness.
  • Results develop over several months and can last up to 2 years.

• CaHA:
  • Suitable to add volume in areas like the cheeks, jawline, and hands.
  • Ideal for moderate to severe facial wrinkles and folds.
  • Provides a lifting and contouring effect.
• PLLA:
  • Focused on facial volume loss and correcting deeper lines like nasolabial folds. Often used as an alternative to tear trough filler.
  • Best for generalised facial volume loss due to aging or lipoatrophy.
  • Primarily for overall volume restoration rather than precise contouring.

• CaHA:
  • Usually injected with a cannula into deeper dermal layers.
  • Precise placement is important to avoid lumps or granulomas.
• PLLA:
  • Injected into deeper dermal or subcutaneous layers.
  • Requires 2-4 sessions spaced several weeks apart.
  • Proper dilution is necessary to avoid complications like nodules.

• CaHA:
  • Common side effects: swelling, bruising, and redness at the injection site.
  • Rare risk of granuloma formation.
• PLLA:
  • Similar common side effects as CaHA.
  • Slightly higher risk of nodules if not properly diluted.

CaHA and PLLA are both effective for facial rejuvenation but address different needs. CaHA is ideal for immediate contouring and provides collagen stimulation over time. PLLA is designed for a gradual increase in volume with long-term collagen production. Your choice between the two depends on whether you want immediate results or a gradual improvement in facial volume.
