What is hyaluronic acid filler? It is not a new concept. After years of use, HA fillers remain a core product category for clinics and distributors. However, choosing the right filler is not always easy. Different gels can perform differently based on their structure, rheological properties, and intended treatment area.
The Revisage® product line is designed for different aesthetic purposes and uses high-purity hyaluronic acid with a high cross-linking density achieved with a low amount of cross-linking agent. This formulation is designed to provide strong structural support and lasting performance. For specifications, indication information, or other details about specific models, please contact us directly.
Quick Answers
How long does hyaluronic acid filler last?
Most HA fillers last around 6–18 months, depending on the product and treatment area.Will hyaluronic acid filler make the face look stiff?
Not necessarily. A natural result depends on using the right filler for the target area and avoiding excessive volume.Can HA filler be dissolved?
In some cases, yes. Hyaluronidase can break down HA filler when needed.
Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan found in the skin, joints, and connective tissues. One of its key properties is its ability to bind water and maintain tissue hydration.
Natural HA has a short half-life and is rapidly degraded by hyaluronidase. HA used in injectable fillers is therefore usually cross-linked, commonly with BDDE, to form a three-dimensional network that improves resistance to enzymatic degradation and extends its duration.
HA fillers are often described as monophasic or biphasic based on their gel structure:
Monophasic: A homogeneous gel with smooth extrusion, often used for precise areas and natural transitions, such as tear troughs and perioral fine lines.
Biphasic: A formulation containing HA particles dispersed in a gel phase, generally offering stronger structural support for deeper filling and contouring, such as the nose, chin, and cheeks.
HA filler mainly works by adding volume and supporting the surrounding tissue. HA also binds water, which contributes to the overall volume of the injected gel.
Facial Contouring:
For areas such as the chin, jawline, and cheeks, fillers with stronger lifting capacity and resistance to deformation may be selected.
Volume Restoration:
HA fillers can address volume loss in areas such as the cheeks, temples, and nasolabial folds. Product selection depends on the required support and tissue characteristics.
Fine Correction:
Softer, more flexible gels are often used for areas such as the lips and fine lines, where smooth integration is important.
Yes. Combination treatment can be considered when different products target different aesthetic concerns.
Botulinum Toxin + HA Filler: Botulinum toxin reduces dynamic expression lines by acting on muscle activity, while HA filler addresses existing static depressions and provides structural correction. Together, they can target different aspects of facial aging. See our article on Botulinum Toxin + HA Filler Combination Treatment for more details.
CaHA (Calcium Hydroxylapatite) + HA Filler: CaHA provides filling and can also support collagen production. The combination may be considered when both contouring and skin quality are treatment goals. See our article on CaHA + HA Filler Combination Treatment for more details.
For clinics and distributors, product selection should focus on five key areas:
1. Market authorization: Check the product's applicable regulatory approval or market authorization, such as CFDA marking or ISO approval where applicable.
2. Residual BDDE: Residual cross-linking agent should meet applicable quality and safety requirements.
3. Rheological properties: G′, cohesivity, and extrusion force help describe how a filler behaves during injection and after placement. These properties should match the treatment area and intended use.
4. Sterile manufacturing: Production should follow appropriate GMP standards, with validated sterilization and quality-control processes.
5. ODM support: For distributors, customized packaging, documentation, registration support, and stable supply can be as important as the product itself.
Most HA fillers last around 6–18 months. Results are visible immediately after injection, while swelling may take 1–2 weeks to settle.
HA is naturally broken down by the body, so repeat treatment may be needed when the effect fades.
Hyaluronic acid filler remains a foundational product in the soft-tissue filler market, but different products are designed for different uses and can perform differently.
