Types of Fillers: Your Guide to Volumizing Injectables

Navigating the world of dermal fillers can be both exciting and overwhelming, especially with the multitude of options available today. Whether you’re looking to smooth out wrinkles, add volume to your lips, or enhance your facial contours, understanding the different types of fillers can be the first step in achieving your aesthetic goals. 

In this detailed guide, we’ll delve into various filler options such as hyaluronic acid-based formulas, collagen stimulators, and more, to help you make an educated decision that best suits your needs.

What are Dermal Fillers?

Dermal fillers are injectable materials that serve multiple purposes in facial rejuvenation. Primarily, they are used to reduce the appearance of facial wrinkles and fine lines. Additionally, these fillers restore lost volume to sagging or hollow areas of the face. They offer a youthful, rejuvenated look without the need for surgical intervention.

Versatile and customizable

One of the standout qualities of dermal fillers is their versatility. There are various formulations carefully chosen to address distinct skin concerns. Hyaluronic acid fillers, for example, are often recommended for adding plumpness to lips or smoothing out nasolabial folds. 

On the other hand, calcium hydroxylapatite-based fillers like Radiesse are generally used for deeper wrinkles and enhancing facial contours. Poly-L-lactic acid fillers like Sculptra stimulate your skin’s natural collagen production, making them ideal for filling in larger areas of volume loss over time.

Range of effects

The effects of dermal fillers can vary based on your personal preferences and the skill of your injector. Some fillers offer immediate results, while others designed to encourage natural collagen production may take a bit longer to show their full effects.

Categories of Fillers

As cosmetic dermatology evolves, dermal fillers have become a popular option for those looking to combat signs of aging or correct acne scars. Whether you aim to erase fine lines or restore lost facial volume due to aging, there’s likely a filler tailored to meet your specific needs.

Hyaluronic acid fillers

Among the most commonly used facial fillers are those made of hyaluronic acid (HA), a naturally occurring substance found in various tissues throughout the body. Popular brand names such as Juvederm and Restylane have become synonymous with this category of fillers, both of which are FDA-approved for facial rejuvenation.

These injectable fillers are versatile in their applications, often deployed for treating areas such as nasolabial folds, marionette lines, and smile lines. They’re also highly effective in adding volume to areas like the jawline and lips. HA fillers are often preferred due to their excellent safety profile, and because they are a naturally occurring substance, they are biocompatible and carry a lower risk of allergic reactions.

Collagen-based fillers

Collagen fillers capitalize on collagen, a naturally occurring protein that serves as a fundamental building block for our skin, bones, and connective tissues. Being biodegradable, they gradually dissolve over time. These fillers are commonly used for treating fine lines, wrinkles, and areas around the eyes, such as crow’s feet. 

Belotero and other brand names offer collagen-based solutions that provide subtle, natural-looking results. These are an excellent choice for those looking for temporary but effective treatment for less severe facial wrinkles and lines.

Calcium hydroxylapatite fillers

Calcium hydroxylapatite, or CaHA, is a mineral-like compound found naturally in human bones. It is used in thicker filler formulations like Radiesse, making it suitable for treating deeper wrinkles, folds, and even restoring facial volume in areas like the cheeks. 

These microspheres of CaHA are often recommended for contouring facial features as well, providing a more sculpted appearance. Due to their thicker consistency, these fillers provide a long-lasting effect, making them a choice worth considering for those looking for more extended relief from volume loss and deeper wrinkles.

Poly-L-lactic acid fillers

Poly-L-lactic acid, or PLLA, is a synthetic but biodegradable material. Brand names like Sculptra fall into this category, and these fillers are unique in that they stimulate your skin’s natural collagen production. This makes them particularly effective for treating larger areas of volume loss, like hollow cheeks or temples, as well as nasolabial folds

Because they work by promoting collagen growth, the results are not immediate but develop over a series of treatments, offering a more long-term solution for facial rejuvenation.

Polymethylmethacrylate (PMMA) fillers

Polymethylmethacrylate, commonly known as PMMA, is a non-biodegradable synthetic material. Brands like Bellafill offer PMMA-based fillers, which are often used for treating deeper facial creases, filling in acne scars and sculpting the jawline

These fillers combine PMMA microspheres with a collagen gel base, providing both immediate and longer-lasting results. Due to the PMMA’s non-biodegradable nature, results from these fillers can last up to 5 years, which makes it critical to have these injections performed by a highly skilled, board-certified injector to ensure optimal outcomes.

Where Can Fillers Be Used?

Lower face and mouth

Dermal filler injections are incredibly versatile, capable of treating a range of aesthetic concerns across various areas of the face. One of the main attractions for many people is the ability of dermal fillers to smooth out smile lines, those creases that extend from the nose down to the corners of the mouth. Additionally, fillers like Restylane Refyne are frequently used to address nasolabial folds and marionette lines that can give the mouth a downturned appearance.

Lip lines, sometimes referred to as “smoker’s lines,” can also be treated effectively with specific filler types such as Juvederm Volbella and Restylane Silk, which are designed for delicate skin areas. In contrast, if you’re looking to add more definition to your jawline or enhance the cheeks’ natural elevation, fillers like Restylane Lyft are often recommended. This particular filler is FDA-approved for cheek augmentation and can significantly improve facial volume.

Upper and mid-face

Moreover, dermal fillers can also tackle deeper facial wrinkles, including frown lines between the eyebrows, as well as crow’s feet at the corners of the eyes. Voluma, a brand under the Juvederm umbrella, is particularly effective in restoring volume to the mid-face region. Some people even opt for filler treatment to correct under-eye hollows, often using softer hyaluronic acid fillers to delicately treat this sensitive area.

Hand rejuvenation

Just like the face, our hands also show signs of aging, such as wrinkles, loss of volume, and visible veins or tendons. Dermal fillers offer an effective solution for revitalizing the appearance of your hands, making them look more youthful and smoother. This treatment aims to restore lost volume, diminish fine lines, and make veins and tendons less prominent. 

Brands commonly used for hand treatments include Radiesse and hyaluronic acid-based fillers like Restylane. By opting for dermal fillers for your hands, you’re investing in a comprehensive approach to anti-aging that addresses more than just your facial features.

Fillers vs. Plastic Surgery

When it comes to facial rejuvenation, it’s worth noting the difference between cosmetic injections and plastic surgery offerings. Dermal fillers present a less invasive and more budget-friendly alternative to surgical interventions like plastic surgery. 

Unlike traditional cosmetic procedures, such as liposuction, which removes excess fat, or fat grafting, which involves transferring fat from one area of the body to another, dermal fillers require minimal to no downtime. This means you can resume your regular activities almost immediately after the procedure, an advantage that has made fillers increasingly popular for those who want quick results without the extended recovery period associated with surgical options. 

It’s also worth noting that dermal fillers offer a degree of reversibility; some hyaluronic acid fillers can be dissolved if the outcome isn’t as expected. This flexibility is often not available with more permanent cosmetic surgery solutions. Therefore, if you’re looking for a quick yet effective way to address your facial concerns, dermal fillers might be the right option for you.

What to Consider Before Getting Fillers

Injector credentials

When considering dermal fillers, choosing the right healthcare provider is crucial for a successful outcome. Always prioritize licensed medical nurse injectors, board-certified dermatologists or plastic surgeons for your treatment. These professionals undergo extensive training in facial anatomy and injection techniques, ensuring a safer procedure with optimal results. 

It’s also advisable to check their reviews and perhaps see before-and-after pictures of previous clients. This will give you a better sense of their expertise and what you can expect from your treatment. 

Your injector should be well-versed in the types of dermal fillers available, be it hyaluronic acid fillers, collagen fillers, or any other, to recommend the most appropriate option for your specific needs.

Side effects and allergic reactions

Though dermal fillers are generally considered safe, it’s crucial to be aware of possible side effects and the potential for allergic reactions. Common side effects include temporary swelling, redness, and minor discomfort at the injection site. Bruising is also a possibility, depending on how easily you bruise and the specific area being treated. It’s important to discuss your medical history and any past allergic reactions with your healthcare provider. 

Tests may be conducted to check for allergies, especially if you’re considering fillers made from substances other than hyaluronic acid, which is a naturally occurring substance in the body. If you have sensitive skin or known allergies, be sure to bring this up during your consultation to help your injector determine the most biocompatible filler material for you.

Downtime and aftercare

One of the major benefits of dermal filler injections is their minimal downtime, allowing you to return to your daily activities almost immediately. However, some residual effects like swelling or bruising may take a few days to subside. Therefore, if you have an important event or meeting, you may want to schedule your treatment well in advance. 

Post-treatment, it’s crucial to adhere to the aftercare guidelines provided by your injector. This often includes avoiding excessive sun exposure, strenuous exercise, and certain skincare products for a set period. Adhering to these guidelines not only minimizes side effects but also prolongs the longevity of your results. 

Some fillers may also require touch-ups or maintenance sessions, so it’s wise to discuss this with your healthcare provider to keep your look fresh and vibrant.


Whether you’re looking to treat fine lines, restore lost volume, or achieve a more youthful appearance, dermal fillers offer a broad array of solutions. By understanding the different types of dermal fillers and their applications, you can make a more informed decision about your cosmetic procedures. Consult with a professional to discuss your unique needs and tailor a treatment that best suits you.
