When people search for information about cosmetic injectables, they often want a clear explanation of how fillers work, what types are available, and what results they can realistically expect. Dermal fillers are a widely used medical procedure designed to address volume loss, soften facial wrinkles, and enhance facial structure.
For patients in San Jose, CA, this guide explains how dermal fillers work, the types of dermal fillers commonly used, and what areas they are designed to enhance—using straightforward, educational language.
Understanding Dermal Fillers

Dermal fillers are injectable fillers placed beneath the skin to restore volume, support facial structure, and soften wrinkles and skin folds. Unlike neurotoxin treatments that affect muscle movement, fillers work by physically adding volume or structure to specific areas of the face.
Most fillers are made from substances that are naturally occurring in the body or closely mimic them. When used appropriately, they integrate smoothly with the skin and underlying tissue.
Dermal filler injections are commonly used to address:
- Facial volume loss
- Deep creases and folds
- Changes related to aging or facial fat loss
- Structural balance and contour
Types of Dermal Fillers
Understanding the type of filler used is important, as each is designed for different purposes.
Hyaluronic Acid Fillers
A hyaluronic acid filler is one of the most commonly used options. Hyaluronic acid is naturally found in the skin and helps retain moisture and volume.
Common uses include:
- Lips
- Cheeks
- Under-eye hollows
- Nasolabial folds
Calcium-Based Fillers
Fillers made with calcium hydroxylapatite provide more structural support and are often used in areas requiring deeper volume restoration.
Common uses include:
- Cheeks
- Jawline
- Areas with more significant volume loss
Collagen-Stimulating Fillers
Some fillers work by encouraging the body to produce its own collagen over time. Poly L lactic acid is one such material used to gradually improve volume and skin structure.
These fillers are often used when the goal is gradual, longer-term volume restoration.
Fillers include different formulations because no single product is ideal for every area or concern.

How Dermal Fillers Restore Volume
As the face ages, facial fat naturally diminishes and shifts. This can lead to hollowing, sagging, and deeper facial wrinkles. A carefully planned filler treatment helps restore volume in areas where support has been lost.
Dermal fillers can help:
- Replace lost facial volume
- Support the skin from beneath
- Improve facial balance and proportion
The goal is enhancement, not overcorrection.
What Areas Dermal Fillers Enhance
Dermal fillers are used to enhance specific facial areas while maintaining natural proportions.
Common treatment areas include:
- Cheeks for mid-face support
- Lips for shape and hydration
- Chin and jawline for balance
- Nasolabial folds and smile lines
- Areas affected by wrinkles and skin folds
Each area requires a different approach and often a different type of filler.
The Dermal Filler Procedure: What to Expect
A dermal filler procedure is typically performed in-office.
During treatment:
- The provider evaluates facial anatomy and volume loss
- Injection points are planned carefully
- Small amounts of filler are placed at each injection site
The process is considered a minimally invasive medical procedure. Mild swelling or bruising can occur but usually resolves within days.
Safety, Side Effects, and Regulation
Dermal fillers used in clinical settings are FDA approved and supported by research. Information about approved filler materials is regulated by the U.S. Food and Drug Administration.
As with any medical procedure, there are potential risks. Possible side effects include:
- Temporary swelling or redness
- Bruising at the injection site
- Rarely, an allergic reaction
Providers review medical history carefully to minimize risk and ensure fillers are used appropriately.
How Providers Choose the Right Filler

There is no one-size-fits-all approach to filler treatment.
Providers consider:
- Facial anatomy and bone structure
- Skin thickness and elasticity
- Degree of volume loss
- Areas being treated
- Desired level of enhancement
The best option depends on the individual’s facial structure and goals.
