Dermal Filler Types Explained: HA, Juvederm, Restylane

If you have started researching dermal fillers, you have probably run into a wall of brand names: Juvederm, Restylane, RHA, Sculptra, Radiesse and more. It can feel like you need a chemistry degree just to book a consultation. The good news is that the landscape is simpler than it looks. Once you understand the handful of filler families and what each is generally good at, the choices start to make sense. This guide walks through the main dermal filler types, how they differ, and how a skilled injector decides which one belongs in your face.

What Are Dermal Fillers, and What Is HA?

Dermal fillers are gel-like substances placed under the skin to restore volume, smooth folds, and refine or enhance a feature. The large majority of modern fillers are hyaluronic acid (HA) based. HA is not a foreign chemical. It is a sugar molecule your body already makes, and one of its jobs is to hold onto water. That water-attracting quality is exactly why HA works so well as a filler: it adds soft, natural-looking volume and integrates smoothly into the tissue.

Two features make HA fillers especially popular. First, they are highly customizable, because manufacturers can tune the gel to be firm and lifting or soft and spreadable. Second, and importantly, HA fillers are generally reversible. If needed, an injector can use an enzyme called hyaluronidase to dissolve the product. That built-in "undo button" is a real source of peace of mind for many patients.

The Main Hyaluronic Acid Families

Most HA fillers belong to one of a few product families. Each family includes several formulations designed for different depths and purposes, so the family name is really a starting point, not a single product.

Juvederm

Juvederm is one of the most widely used HA lines. It includes softer gels often chosen for the lips (such as Volbella and Ultra) and firmer, more supportive gels used to add structure and lift to areas like the cheeks (such as Voluma). Juvederm products tend to have a smooth, cohesive feel that many injectors like for creating seamless volume.

Restylane

Restylane is another established HA family with a broad range of formulations. Some, like Kysse, are designed with lip enhancement and natural movement in mind, while others, like Lyft, are firmer gels used to support and lift areas such as the cheeks. Restylane gels are known for their versatility across many facial areas.

RHA

RHA stands for Resilient Hyaluronic Acid. This line was developed with flexibility in mind, aiming to move naturally with your expressions. That makes RHA a common choice for dynamic, animated areas of the face where you want the result to look natural while you talk, smile, and laugh.

No single family is universally "better." Each includes a spread of products, and a good injector may reach for different brands on different patients, or even mix families across one treatment plan.

Biostimulator Fillers: A Different Approach

Not every filler is HA. A second category, sometimes called biostimulators, works less by adding instant volume and more by prompting your own body to build collagen over time. Sculptra is a well-known collagen-stimulating product, and Radiesse is a calcium-based option. These fillers are chosen for specific goals, such as gradual, foundational restoration of volume across broader areas. They generally are not reversible the way HA fillers are, so injector expertise and conservative planning matter even more. In a consultation, your provider will explain whether an HA filler or a biostimulator better fits your goals.

How an Injector Picks the Right Filler

Here is the part that surprises most people: the "best" filler depends far less on the brand and far more on the area being treated, your anatomy, and the look you are after. A thoughtful injector matches the product's properties to the job.

  • Lips: Soft, flexible gels are usually preferred so the result feels natural and moves well when you speak and smile. You can read more on our lip filler page.
  • Cheeks: This area often calls for firmer, more structural gels that provide lift and restore midface volume. Learn more about cheek filler.
  • Jawline: Definition along the jaw typically benefits from firmer products that hold their shape and create a crisp contour.
  • Under-eyes: This delicate, thin-skinned area demands soft, low-water gels and a light hand, because the wrong product or too much volume shows quickly here.

An experienced provider weighs all of this at once: the gel's firmness, how much it attracts water, how it behaves with movement, and how it will age over the coming months. That judgment is the real product you are paying for.

Reversibility and Safety

One of the reassuring realities of HA fillers is that they can often be dissolved if needed, whether to correct an unwanted result, address a rare complication, or simply because you change your mind. That does not make filler risk-free. Fillers are medical procedures that should be performed by trained, licensed professionals who understand facial anatomy, know how to prevent and manage complications, and place product in the right layer. Choosing a qualified injector in a proper clinical setting is the single most important safety decision you can make.

Why the Injector Matters More Than the Brand

It is tempting to shop for filler the way you shop for a product on a shelf, hunting for the "right" brand name. In reality, the same syringe of the same product can produce a beautiful, natural result in skilled hands or an unnatural one in less experienced hands. Technique, product selection, placement, and dosing decisions all come down to your injector. This is why we encourage patients to choose the person first and let the product follow.

At The Injector Collective, our injectors are independent licensed professionals (RN, NP, and MD) practicing at two open Utah locations, Lehi and Draper. Each injector selects the product and plan that fits you, rather than pushing a one-size-fits-all option.

Ready to Talk Through Your Options?

The best way to figure out which filler is right for you is a conversation with an injector who can assess your face in person. You can browse our providers and book a consultation on our find your injector page. We would love to help you find a natural result you feel great about.

Frequently Asked Questions

What are dermal fillers made of?

Most modern dermal fillers are made of hyaluronic acid (HA), a naturally occurring sugar that your body already produces. HA attracts water and adds soft volume under the skin. Some fillers instead use biostimulators, such as poly-L-lactic acid in Sculptra or a calcium-based material in Radiesse, which prompt your body to build its own collagen over time.

What is the difference between Juvederm and Restylane?

Both are hyaluronic acid filler families, and each includes several formulations for different areas and depths. They differ in gel texture and how they behave in the tissue, so injectors sometimes prefer one over the other for a given goal. Neither line is universally better. The right choice depends on the treatment area, your anatomy, and your injector's judgment.

Which filler is best for lips?

There is no single best lip filler. Injectors usually favor softer, flexible HA gels for the lips so the result looks natural and moves well when you talk and smile. Products such as Juvederm Volbella or Restylane Kysse are common lip choices, but the right one for you is decided in a consultation based on your goals and anatomy.

Can dermal filler be dissolved?

Hyaluronic acid fillers can often be dissolved using an enzyme called hyaluronidase. This lets an injector adjust or reverse a result if needed. Biostimulator fillers like Sculptra and Radiesse generally cannot be dissolved the same way, which is one reason careful, conservative planning matters with those products.

How long do dermal fillers last?

Dermal fillers generally last about 6 to 12 months, though this varies by the specific product, the area treated, and your individual metabolism. Areas with a lot of movement may break the product down faster. Your injector can give you a more precise estimate for the filler and area in your plan.
