As we age, we all slowly lose fat in our face - under our eyes, in our cheeks, and around our mouths, leading to wrinkles, folds, and sagging skin. Restylane is an injectable filler that helps you regain a soft youthful look by adding volume and fullness back into your face. Restylane is safe because it is made of hyaluronic acid, a substance that already occurs naturally in your body. Restylane is commonly injected into the face in the lines that run from the corners of your nose to your mouth (nasolabial folds) as well as the lines that run from the corners of the mouth to the chin (marionette lines). Our board-certified dermatologists also safely inject Restylane into the lips, cheeks, and under-eye area to address static wrinkles and all over fat loss. Restylane is a favorite of our patients because it looks very natural and lasts about four to six months. Restylane also comes in three different formulas to best address specific signs of aging. At Bay Area Cosmetic Dermatology in San Francisco, our doctors are experienced with many different types of dermal fillers and can help you determine which one will best address your cosmetic concerns.

Dr. Kathleen Welsh and Dr. Andrea Hui Austin are the #1 injectors of Restylane Refyne and Defyne in the United States.

Restylane SILK

Restylane Silk is the only FDA-approved filler that is specifically targeted to treat the lips and mouth area. Restylane Silk adds fullness and shape back into the lips, while also minimizing the lines and creases in the lip line and around the mouth. 

Restylane REFYNE

Restylane Refyne is one of the newest fillers to join the Restylane family. This advanced filler uses XpresHAn Technology™ to soften the nasolabial folds and marionette lines, also known as the “laugh lines.” Restylane Refyne softens these lines and creates a more smooth appearance, while still maintaining a natural look. 

Restylane DEFYNE

Restylane Defyne is also new to the Restylane family of fillers but uses XpresHAn Technology to treat deeper laugh lines (nasolabial folds and marionette lines) than Refyne. Refyne and Defyne both use uses innovative cross-linking hyaluronic acid technology and are the only dermal fillers that have been shown in clinical trials to help maintain natural movement and expressions. 


Both men and women can attain softer, natural-looking results with fillers from the Restylane family of products. Restylane dermal fillers are safe for patients with any skin type or tone who would like to address facial volume loss or fill in deep folds and wrinkles. Restylane fillers can also be used to create fuller lips with less lip wrinkles. 

I began noticing signs of aging in my late 30s. Being a dermatologist myself, I was aware that lost volume could be restored with fillers. It’s crucial to entrust your face to a professional whose results consistently deliver a natural look aligned with your goals.About six years ago, Dr. Hui administered fillers to my cheeks, and the effects endured for many years. Recently, I realized that I needed some enhancements, so I traveled from New York to California to see Dr. Austin. This time, we added a few more syringes to my temples and chin, significantly improving my facial harmony. Even when I showed up at work tired after an overnight flight, I received numerous compliments about my rejuvenated appearance!!!Dr. Austin’s expertise in facial anatomy, artistic proportions, and the quality of different fillers is unparalleled. Moreover, her advice on skincare, prevention, and maintaining youthful skin is invaluable. Plus, she is a pleasure to be around, that makes the experience both enjoyable and informative.

I have been a patient of this practice for over 12 years.  I have seen Kathleen Welsh for over 50 visits and have always been pleased with the outcome of my medical treatment.  She is a caring lovely person.  All of my family members have also seen her for acne , mole removal, skin care and fillers.  I travel a distance to my appointments and it is worth every mile.

Where do I begin?!  Dr. Andrea Austin is a talented dermatologist who is passionate about what she does.  I have struggled with acne and severe redness since I was a teenager, and have seen many dermatologists.  Dr. Austin immediately diagnosed rosacea, and put together a plan of action.  For the past year, I have done a combination of VBeam laser, topical, and oral medication.  The difference has been astounding.  What I thought was straight hormonal acne was really rosacea related.   My skin glows now, and I rarely wear make up.  Now that my skin is under control, Dr. Austin has helped me take it to the next level, and we have started a regime of retin A, botox, and restalyne.   She has an artist's eye, and truly makes you look like a younger, better-rested version of yourself!   The office is very professional and easy to work with.  I appreciate the fridge full of seltzers, and their well stocked over the counter products.   Thank you Dr. Austin!

A miracle in San Francisco!! I moved from the East Coast, and so was fairly spoiled with some of the best cosmetic dermatologists in the U.S. However, now my concern is what on earth I will do WITHOUT Dr. He if he ever leaves the Bay Area. I can't say enough how lucky we are to have someone with that kind of natural artistry with filler here. He both incredibly knowledgeable and patient-focused, tailoring treatments and regimens to fit needs/budget and responding to last-minute skin care "emergencies" or concerns. If you are considering Botox, Filler, laser treatments, or peels and are in the Bay Area, I would DEFINITELY give BACD a call.

Always friendly and professional. Dr. Austin has an artistic eye. I appreciate her "we can always do more later" approach, which is allowed me to try things out, take small steps, and feel confident with my decisions. I always leave the office feeling and looking 10 years younger!

What to Expect during RESTYLANE injections

Most patients are surprised at how quick and comfortable a Restylane filler treatment is. Prior to injection, a medical assistant will review an informed consent with you and take “before” photos. After the numbing cream has taken effect, Dr. Kathleen Welsh or Dr. Andrea Hui Austin will use a thin needle to inject the clear gel into areas where you desire more fullness and any lines, folds, or wrinkles that you would like softened. Our board-certified dermatologists are conservative with the amount of filler they will inject, striving subtle, natural-looking results.

How long is recovery after RESTYLANE?

Following treatment, most of the effects of Restylane can be seen immediately. Lines and wrinkles will appear diminished, softer, and smoother. As is the case with any injections, bruising is always a possibility. If you are prone to bruising, we recommend that you discontinue any blood-thinning medications or supplements, if it is safe for you to do so, for about a week prior to your Restylane treatment. For patients receiving Restylane lip injections, the lips may appear swollen for a couple of days before you see your results. Immediately following the treatment, there may be some swelling and redness that occurs at the injection sites, however, this will go away after a few hours. Patients are advised to follow all aftercare instructions to see the best results and they may return to their regular routines immediately. Results are expected to last four to six months. After that time, patients may return for additional treatment.
