Which Dermal Filler is Right for Me?
What is intrinsic aging?
Collagen is a naturally occurring protein produced by the body and serves as the primary structural framework of the skin. It provides firmness, elasticity, and overall facial support. Beginning in the mid-20s, collagen production gradually declines at an estimated rate of approximately one percent per year. As this process continues, the skin slowly loses its ability to maintain volume and resilience. After the age of 40, collagen loss accelerates, leading to visible changes in facial structure and skin quality.
As collagen, fat, and supportive tissue diminish, the skin becomes thinner and less elastic. The result is volume loss, fine lines, deeper wrinkles, dryness, and sagging. These changes are part of intrinsic aging, the natural aging process determined by genetics and time. In addition, repeated facial expressions gradually create etched lines and folds in areas of frequent movement, such as around the mouth, eyes, and forehead.
What is extrinsic aging?
Extrinsic aging further compounds these changes. Chronic sun exposure accelerates collagen breakdown through a process known as photoaging. Over time, ultraviolet radiation damages the skin’s supportive framework, resulting in deeper wrinkles, increased skin laxity, uneven texture, dullness, and pigmentation changes. Together, intrinsic aging and environmental factors lead to a loss of youthful contours and facial definition.
What do dermal fillers do?
Dermal fillers offer an effective, non-surgical solution to address these age-related changes. By restoring lost volume, enhancing facial structure, and improving skin quality, fillers can soften wrinkles, redefine contours, and rejuvenate the overall appearance. In certain formulations, fillers also stimulate the body’s natural collagen production, helping to improve skin integrity over time. Injectable dermal fillers are among the most commonly requested aesthetic treatments for facial aging, with high satisfaction rates among both women and men across a wide range of age groups.
Dermal filler treatments are minimally invasive and typically provide immediate or near-immediate results. Discomfort is usually mild, risks are low when performed by an experienced dermatologist, and downtime is minimal. Treatments are highly customizable, allowing your provider to tailor product selection and placement based on your facial anatomy, concerns, and goals. When performed with precision and restraint, the results appear natural, refreshed, and balanced. The success of dermal filler treatment depends heavily on the medical expertise, aesthetic judgment, and technical skill of the treating dermatologist.
What are dermal fillers?
Dermal fillers are injectable soft-tissue substances designed to restore volume, enhance facial features, and improve the appearance of lines and wrinkles. They are placed beneath the skin at varying depths depending on the treatment area and the type of filler used. Many patients benefit from a customized approach that incorporates more than one filler type to achieve optimal results.
What are the types of dermal fillers?
- Hyaluronic acid (HA) fillers like Juvéderm® and Restylane®, are among the most widely used fillers in aesthetic dermatology. Hyaluronic acid is a naturally occurring sugar found throughout the body, with high concentrations in the skin, joints, and eyes. Its ability to attract and retain water makes it essential for skin hydration and volume. HA fillers improve fine lines, wrinkles, and volume loss while enhancing skin hydration. These fillers are available in varying consistencies, allowing precise customization. Thicker formulations are used to restore midface volume, contour the cheeks and jawline, and lift areas affected by sagging, while thinner formulations are ideal for softening fine lines. Results are visible immediately and typically last from six months to two years, depending on the product and treatment area. HA fillers are particularly valued for their versatility, predictability, and excellent safety profile.
- Calcium hydroxyapatite (CaHA) fillers, such as Radiesse®, are biocompatible substances that mimic a mineral naturally found in bones. As aging progresses, not only does the skin thin, but underlying fat, muscle, and bone structure also diminish or shift. CaHA fillers are FDA-approved to correct moderate to severe facial wrinkles and folds and to address volume loss related to facial aging. These fillers provide immediate correction while also stimulating collagen production. Lidocaine is often incorporated to improve comfort during treatment. Results generally last one year or longer.
- Poly-L-lactic acid (PLLA) like Sculptra®, is a collagen-stimulating injectable rather than a traditional volumizing filler. It works by gradually encouraging the body to rebuild its own collagen, improving facial structure and skin firmness over time. PLLA is particularly effective for deeper wrinkles, facial hollowing, and generalized volume loss. Results develop gradually over several months and can last more than two years. Because PLLA injections are placed deeper within the skin, lidocaine is commonly used for comfort. Treatment typically requires a series of sessions spaced several weeks apart to achieve optimal and long-lasting results. PLLA has a long history of use and an established safety record.
- Polymethylmethacrylate (PMMA) fillers like Bellafill®, are composed of bovine collagen combined with microspheres that provide long-term structural support. These fillers offer immediate correction while stimulating the body to produce new collagen around the microspheres. PMMA fillers are FDA-approved for the treatment of smile lines and certain types of depressed acne scars. Results can last several years, making them a long-lasting option for carefully selected patients.
Your dermatological consultation
A comprehensive consultation is an essential part of successful dermal filler treatment. Your visit will begin with a detailed discussion of your medical history, skin concerns, and aesthetic goals. Your board-certified dermatologist at Palo Alto Dermatology Institute will carefully examine your facial anatomy, skin quality, and areas of volume loss to develop a personalized treatment plan. Recommendations may include one or more types of dermal fillers based on your individual needs and goals, and your provider will clearly explain the rationale, expected outcomes, and longevity of each option.
Certain conditions may require postponing treatment, such as active skin infections or the use of blood-thinning medications, including aspirin, NSAIDs, and some herbal supplements. These factors will be reviewed during your consultation to ensure safety and optimal results.
When treatment proceeds, photographs may be taken to document baseline appearance and outcomes. The skin will be thoroughly cleansed, and topical or injectable numbing agents may be used for comfort. Many fillers also contain lidocaine to minimize discomfort during injection.
Each dermal filler has specific properties that determine where and how it is used, as well as how long results are expected to last. Careful product selection and precise placement are critical to achieving natural, harmonious results.
