Lips change with time in ways that are easy to feel but hard to pinpoint. The border of the upper lip softens, fullness thins, small vertical lines appear above the mouth, and the corners may begin to turn downward. Some patients have always had thin or uneven lips and simply want more balance. Lip augmentation with dermal fillers restores shape, definition, and soft volume without surgery, and when it is done with restraint, the result looks like your own lips on a good day.
Dr. Melanie Ho Erb has spent much of her career teaching other physicians to work in the most delicate areas of the face, training oculoplastic fellows at Eyesthetica in Los Angeles and ophthalmology residents at UC Irvine and USC. An oculoplastic surgeon, she earned her medical degree at UC Irvine, completed her surgical internship and ophthalmology residency there, and finished a two-year fellowship in oculoplastic surgery approved by the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS). She personally performs every filler injection at her Irvine practice, bringing a surgeon’s precision to a treatment where a very small amount of product changes the result.
“Good lip filler should make people notice that you look rested and well, not that you had your lips done. I would rather add a little at a time and have a patient come back for more than place too much at once.”
I have also started getting lip fillers as well, and my results are natural and proportionate to my facial features.
How Lip Fillers Restore Shape and Volume
Lip fillers are smooth hyaluronic acid (HA) gels placed precisely within and along the lips. Hyaluronic acid occurs naturally in the skin and attracts water, which helps the lips look hydrated and soft rather than stiff. Depending on your goals, Dr. Erb may use filler to:
- Define the lip border: sharpen the outline of the upper lip where it has blurred with age.
- Restore fullness: replace volume that has thinned over time.
- Improve balance: correct differences between the left and right sides or between the upper and lower lips.
- Soften vertical lip lines: smooth the fine lines that form above the upper lip.
- Support the corners of the mouth: gently lift corners that have started to turn downward.
Because hyaluronic acid fillers can be dissolved with an enzyme called hyaluronidase, lip treatment is adjustable and reversible if needed.
Common Lip Concerns We Treat in Irvine
Patients from Irvine, Orange County, and Los Angeles come to Dr. Erb with a range of goals. Many notice that their lips have thinned with age and lipstick no longer holds a clean line. Others have naturally thin lips and want subtle enhancement that suits their face. Some are bothered by asymmetry, while others are looking to correct filler placed elsewhere that looks overdone or has migrated above the lip line.
Dr. Erb’s approach is guided by proportion. In most faces, the lower lip is slightly fuller than the upper lip, and the lips should be in harmony with the nose, chin, and cheeks. Her goal is never “duck lips” or an obviously treated look. She plans each treatment around your natural lip shape, adding volume where it belongs and leaving alone what already works.
Lip Filler Products Dr. Erb Uses
Dr. Erb selects from premium hyaluronic acid fillers, including options within the Juvéderm and Restylane families. Juvéderm Ultra and Restylane Classic are both FDA approved for lip augmentation in adults over 21, and both contain lidocaine for added comfort. The right product depends on how much structure versus softness your lips need, and Dr. Erb will explain her recommendation during your consultation.
Why an Oculoplastic Surgeon for Lip Filler
Lip augmentation looks simple, but the lips have a rich blood supply and very little room for error. An oculoplastic surgeon trains for years in facial anatomy, vascular structures, and the fine adjustments required around the eyes, which are among the most demanding areas of the face to treat. That same training shapes how Dr. Erb approaches the lips, with careful product placement, conservative volumes, and a clear understanding of what to avoid.
Patients in Irvine, Orange County, and Los Angeles choose Dr. Erb for lip filler because she:
- Personally performs every injection
- Places small amounts in stages for natural results
- Considers the lips as part of the whole face
- Uses numbing cream, ice packs, and lidocaine-containing fillers for comfort
- Gives honest guidance when less filler, or none, is the better choice
What to Expect From Lip Filler Treatment
Your visit begins with a consultation in which Dr. Erb reviews your goals, medical history, and any prior filler treatment. If you have a history of cold sores, let her know, since lip injections can trigger an outbreak and a preventive medication may be recommended. Numbing cream and ice packs are applied before treatment, and the filler itself contains a local anesthetic.
Swelling is normal after lip filler and is usually most noticeable during the first day or two. It typically settles within one to two weeks, which is when you will see your true result. Mild bruising or tenderness may also occur. Most patients return to work and daily activities right away, though it is wise to avoid strenuous exercise for about a day. Lip filler usually lasts about 6 to 12 months, since the lips move constantly and break down filler faster than other areas.
Serious complications are rare, but any filler injection carries a small risk of affecting blood flow. If you notice severe or worsening pain, skin that turns pale, gray, or dusky, or any change in your vision after treatment, contact the office immediately. If you cannot reach the office or have vision changes, seek emergency medical care right away.
Frequently Asked Questions About Lip Fillers
-
Most patients enjoy results for about 6 to 12 months. Lips tend to metabolize filler more quickly than the cheeks or under-eye area because they move so often, so periodic touch-ups help maintain the result.
-
No. Dr. Erb places filler conservatively and builds in stages when needed, so your lips stay in proportion with your face. Her philosophy across all dermal filler treatments is subtle, natural enhancement.
-
The lips are sensitive, but discomfort is usually well controlled. Dr. Erb uses numbing cream and ice packs, and the fillers she uses for the lips contain lidocaine.
-
Swelling usually peaks in the first day or two and settles over one to two weeks. Many patients schedule treatment at least two weeks before a special event.
-
Often, yes. Hyaluronic acid filler can be dissolved with hyaluronidase, and after the tissue settles, Dr. Erb can reshape the lips with a more measured approach.
-
Yes. Many patients pair lip filler with fillers for marionette lines, cheek augmentation, or neurotoxin injections for a balanced lower face.
