Dermal Filler Comparison Guide by Type, Area & Longevity

Hyaluronic acid is a naturally occurring polysaccharide that binds water and plumps tissue. HA fillers dominate the market because they're reversible (hyaluronidase can dissolve them if needed), work across most face zones, and feel natural. They come in different cross-linking densities—looser formulations for fine lines and lips, denser for deeper folds and cheeks. Typical duration is 6–12 months, though some newer formulations claim 18+ months. HA fillers are generally the lowest-cost entry for your practice and the most forgiving for newer injectors. Examples include Juvéderm and Restylane families. The trade-off: they require more frequent touch-ups than longer-lasting alternatives, which can drive patient retention but also demand on your schedule.

Calcium hydroxylapatite is a mineral compound found naturally in bone. CaHA fillers are denser and more robust than HA, making them ideal for deeper folds, cheek augmentation, and jawline definition. They stimulate mild collagen remodeling over time, potentially extending results to 12–18 months. CaHA is not reversible with hyaluronidase, so precise placement is critical. Cost per unit is typically higher than HA but justified by longevity and the structural lift patients perceive. Radiesse is the primary CaHA product. This filler appeals to patients seeking more dramatic, longer-lasting results and is a natural upsell from HA for repeat clients.

Poly-L-lactic acid is a biocompatible synthetic polymer that doesn't fill immediately; instead, it triggers the body's own collagen production over 4–6 weeks. Results peak around 3 months and can last 2+ years. PLLA is best for global volume loss, cheeks, temples, and jawline—areas needing gradual, natural-looking restoration rather than instant plumping. It requires multiple treatment sessions (typically 3–4 spaced weeks apart) and patient education about delayed gratification. Cost per treatment is moderate, but the multi-session protocol increases total revenue per patient. Sculptra is the market leader. PLLA attracts patients with realistic timelines and those seeking preventive, long-term rejuvenation.

Recent FDA approvals have expanded the filler toolkit. RHA (Resilient Hyaluronic Acid) is a newer HA technology designed to move naturally with facial expression, particularly suited to midface augmentation and dynamic zones. Restylane Contour received FDA approval for temple hollowing correction, addressing a specific anatomical need. These dynamic fillers represent premium pricing opportunities—they command higher per-unit costs than standard HA because they're newer, have specialized indications, and appeal to patients seeking cutting-edge results. Longevity is typically 12–18 months. Verify current FDA clearances and approved indications on the FDA website before marketing any new product.

Longevity drives economics. HA fillers (6–12 months) generate frequent repeat visits—good for retention, demanding on scheduling. CaHA and PLLA (12–24 months) reduce visit frequency but command higher per-treatment fees. Newer dynamic fillers sit at the premium end. Acquisition cost varies by supplier, volume discounts, and rebate programs (e.g., Allē, Aspire, Evolus Rewards)—negotiate these aggressively and factor them into your margin model. Patient expectations matter: someone seeking a quick lip refresh differs from someone investing in long-term midface restoration. Educate patients on trade-offs: HA's reversibility vs. CaHA's permanence, PLLA's delayed results vs. immediate gratification, and premium dynamic fillers' natural movement. This positions you as a consultant, not just an injector.

Start with one or two HA products in different viscosities (fine-line and deep-fold) to master technique and build patient base. Add CaHA once you're confident in deeper placement and have demand for structural augmentation. PLLA requires patient education and a booking system for multi-session protocols—implement this only when you have staff capacity. Dynamic and specialty fillers are best added after you've established baseline revenue and can justify premium pricing. Monitor inventory turnover, shelf life, and storage requirements. Track patient satisfaction and longevity claims in your records—this data informs future purchasing and helps you defend pricing. Consult your state board and the FDA (fda.gov) on approved indications for each product; never market off-label claims without documented evidence.
