Hyaluronic Acid vs. Calcium Hydroxylapatite: Which Filler is Right for You?

Facial fillers have revolutionized non-surgical cosmetic enhancements, offering effective solutions for restoring lost volume, smoothing wrinkles, and enhancing facial contours. Among the most popular types of dermal fillers are hyaluronic acid (HA) and calcium hydroxylapatite (CaHA). While both fillers provide remarkable rejuvenation, they have distinct properties, benefits, and best-use applications. At Creative Facial Aesthetics in NYC, we help you choose the right filler based on your aesthetic goals, skin type, and desired longevity of results.

What is Hyaluronic Acid (HA)?

Hyaluronic acid is a naturally occurring substance in the skin that helps retain moisture and elasticity. HA fillers, such as Juvederm® and Restylane®, are composed of a soft, gel-like substance that instantly plumps and hydrates the skin upon injection. Benefits of HA fillers include:

• Immediate results: Noticeable plumping and smoothing right after treatment.
• Hydration boost: HA attracts water molecules, keeping the skin hydrated and youthful.
• Reversible: HA fillers can be dissolved with hyaluronidase if adjustments are needed.
• Versatile applications: Ideal for lip enhancement, nasolabial folds, cheek augmentation, and under-eye hollows.
• Short to moderate longevity: Results last 6 to 18 months, depending on the formulation and treatment area.

What is Calcium Hydroxylapatite (CaHA)?

Calcium hydroxylapatite is a biocompatible, calcium-based filler found in products like Radiesse®. Unlike HA, CaHA fillers are firmer in consistency and stimulate natural collagen production, offering longer-lasting structural support to the skin. Benefits of CaHa fillers include:

• Collagen stimulation: Encourages the body to produce collagen, leading to longer-term improvement.
• More structure and volume: Best for jawline contouring, cheek augmentation, and deep wrinkles.
• Durability: Results typically last 12 to 24 months, longer than most HA fillers.
• Firmer consistency: Provides greater support for areas that require structural enhancement.

How Do They Compare?

Both fillers provide immediate results, but CaHA fillers gradually improve skin texture over time by stimulating collagen production. HA fillers last between 6 to 18 months, while CaHA fillers typically last longer, between 12 to 24 months. HA fillers are reversible with hyaluronidase, making them an excellent choice for those who may want to adjust their results, whereas CaHA fillers are not reversible.

If hydration and a soft, natural feel are priorities, HA fillers are a great option, especially for lips, fine lines, and under-eye areas. For individuals seeking more structural support, such as jawline definition and deep wrinkle treatment, CaHA fillers are the better choice due to their firmer consistency. The decision between the two ultimately depends on your aesthetic goals and the areas of concern.

Which Filler is Right for You?

If you want a softer, more natural look with hydration, HA fillers are ideal. If you’re looking for longer-lasting structural support and collagen stimulation, CaHA fillers are a better choice. Those who may want a reversible option should opt for HA fillers, while individuals seeking contouring for areas like the jawline may find CaHA fillers more beneficial. Many of our patients choose both fillers used to address different areas.
