If you’re looking to smooth wrinkles, restore volume, or enhance facial contours without surgery, hyaluronic acid (HA) fillers offer a proven and non-invasive solution. These injectable treatments help rejuvenate the skin by restoring hydration and fullness where it’s been lost.
At Metropolis Dermatology in Pasadena, we offer tailored HA filler treatments to address everything from deep facial lines to subtle volume loss—helping you achieve refreshed, natural-looking results that align with your unique goals.
What Are Hyaluronic Acid Fillers?
Hyaluronic acid fillers are gel-based injectables made with a substance naturally found in the body—one that plays a key role in maintaining skin hydration and elasticity. Once injected, HA fillers bind to water in the skin to provide immediate volume, improved contour, and a smoother texture. These treatments are particularly effective for rejuvenating targeted facial areas and offer both subtle enhancements and more dramatic contouring, depending on the desired outcome.
Areas Commonly Treated
HA fillers are versatile and can be used to enhance or correct a number of areas, including:
- Cheeks: Restores fullness to flattened or hollow areas.
- Lips: Adds volume, shape, and hydration for a plumper pout.
- Nasolabial Folds: Softens the deep creases between the nose and mouth.
- Marionette Lines: Reduces the lines that extend downward from the corners of the mouth.
- Jawline: Defines and sharpens jaw contours.
- Under-Eye Hollows: Fills tear troughs for a brighter, more rested appearance.
Popular HA Filler Brands
We offer several premium HA fillers at Metropolis Dermatology, each selected for its specific advantages and aesthetic properties:
- Juvederm®: Known for smooth texture and lasting results, Juvederm offers options ideal for lips, cheeks, and mid-face enhancement.

What Happens During a Treatment?
- Consultation: Your provider will assess your features and discuss your goals.
- Preparation: A topical numbing cream is applied for comfort.
- Injection: The filler is placed with a fine needle or cannula into targeted areas.
- Post-Care: You may experience mild swelling or bruising for a few days, but most clients return to regular activities immediately.
Treatment usually takes 20 to 30 minutes, with instant visible results.
How Long Do Results Last?
The effects of HA fillers are temporary but long-lasting. Depending on the brand used and treatment area:
- Most results last 6 to 18 months.
- Touch-ups may be recommended annually to maintain your look.
Aftercare Tips:
- Avoid touching or massaging the area for 24 hours
- Postpone intense workouts and sun exposure for 48 hours
- Stay well-hydrated to support healing and optimal results
