Stanford and Harvard alumna Dr. Kathleen Welsh is one of the top providers of BOTOX in the San Francisco Bay Area. She has performed more than 50,000 treatments in the past fifteen years of cosmetic dermatology practice. Her colleague Dr. Andrea Hui Austin has also received years of extensive training in cosmetic dermatology and is a national educator in neuromodulator treatments. Together with their skilled staff of registered nurses, and Garrett Forrest, PA-C, Dr. Welsh and Dr. Hui Austin perform more than 5,000 BOTOX treatments per year. Dr. Welsh has personally trained all of the registered nurses on her staff that inject BOTOX and each of these practitioners is skilled at determining the proper placement and volume of BOTOX to help you achieve your desired results. The results are natural and subtle – no one will ask you if you just had BOTOX, but they may notice that you look rested and refreshed.

What is BOTOX?

BOTOX is an FDA-approved injectable wrinkle relaxer used to safely smooth lines and wrinkles on the face. BOTOX  works by relaxing the over-used muscles underneath the skin to minimize dynamic wrinkles like "Crow's feet" in the corners of the eye, frown lines (also known as “11’s”), forehead furrows, smiles lines, and more. The result is an overall softer and more youthful appearance. In addition, BOTOX can also be used to treat severe headaches, excessive perspiration, and temporal mandibular joint (TMJ) disorder. To learn more about BOTOX, please schedule a cosmetic consultation with one of our San Francisco board-certified dermatologists, our PA, or one of our registered nurses. 

Who should get BOTOX?

Millions of patients worldwide have already been treated with BOTOX, making it the #1 selling product of its kind in the world. If you are unhappy with the wrinkles around your eyes and forehead, you may be a candidate for BOTOX. It not only provides temporary relief from moderate to severe lines and creases, like Crow's feet, frown lines, smile lines, and forehead furrows but can also be used to prevent new wrinkles from forming. If you are looking for a quick, effective, and nonsurgical anti-aging treatment, BOTOX may be the perfect treatment for you.


BOTOX treatments are very simple when performed by one of our highly skilled injectors. A topical numbing cream will first be applied to the injection site. Then, using a very fine needle, one of the providers injects the BOTOX into the treatment area. Most patients find the injections to be painless and, with the topical numbing, you may not feel anything at all! Our skilled medical professionals determine the exact amount of BOTOX that you will need and the ideal placement for individualized and best results. After your BOTOX treatment is complete, you can almost immediately go back to your daily routine.

I've been seeing Dr. Austin for nearly four years now and she is without a doubt the best dermatologist in SF. Dr. Austin is brilliant and ahead of all the latest, cutting edge treatments, warm and collaborative, and extremely perceptive. I go a few times a year for Botox and Clear + Brilliant treatments (mini laser to heal sun damage). My face tends to be very expressive when I talk, so before I started seeing Dr. Austin, I would accumulate frown/squint lines easily. I also have an active lifestyle and spend a lot of time outdoors in the sun. With the minimal number and dosage of treatments each year, my forehead wrinkles have disappeared, sunspots are gone, and my skin looks so healthy, smooth, and glowing to the point that I'm often told I look over a decade younger than my actual age. Dr. Austin is passionate about helping her clients look their best, and her positive, delightful energy pervades the clinic. She gets to know you as a patient and as a person, so the treatments are tailored uniquely for you, your lifestyle, and your goals for appearance. I want a natural, healthy look and we work together to choose treatment plans that best suit me. Dr. Austin is proactive in recommending the best options for your skin while also not over-prescribing, which I find especially helpful given good skincare is not inexpensive. The investment in my skin has been more than worth it.I can't emphasize enough the human touch throughout the office for a pleasant, welcoming, smooth experience. Dr. Austin always remembers to ask about my latest trip or my pup Pecan. All her team is terrific, unfailingly pleasant, professional and responsive. You are immediately made to feel welcome and comfortable, from the front desk to the medical staff working with you and Dr. Austin. (Special shout out to Monica, who does hydro facials and is wonderful). Communications are always transparent and policies are accurately disclosed upfront for no surprises. I look forward to each visit, and hope you will do something wonderful for yourself and visit Dr. Austin at Bay Area Cosmetic Dermatology too. Dr. Austin and her team are a treasure, and I am grateful to have found them.

I've been a patient of Dr. Austin for nearly 10 years and she is the best dermatologist I've ever been to. She has miraculously healed my rosacea which I have struggled with forever. She's also fantastic with Botox - undetectable and completely natural looking. She really listens to her patients which hasn't always been my experience elsewhere. 10/10!

I have been going to BACD for almost 10 years. I have always seen Nurse Mary Krempa. Many moons ago performed Mira Dry on me, which helped reduce my underarm sweating and gave me my confidence back. She has been doing neuromodulators on me for years now and always does such a beautiful and natural job. Mary is literally an earth angel and one of my fav people. I love coming in to see her regularly. She is gorgeous and so is the work she does!

Personally and individually, Dr. Welsh is the REAL Five star Dermatologist in Northern California, worth every penny for her precise injections, treatments and bed side manner. Yes, there are delays sometimes, yes there are many other patients and a filled to the brim schedule, but face it, you are paying to get an appt. with a Harvard Trained MD. You get what you pay for. If you are looking for cheap, you are going to look just that, Cheap. Worth the wait. Worth the money. Your face is worth it. Laura Kyriazis, ESQ.

After a BOTOX treatment, patients can expect some minor swelling and redness at the injection sites. This goes away quickly and is generally not noticeable within about an hour after the treatment. The results following a BOTOX treatment are not immediate. Typically it takes about seven to fourteen days for patients to see their smoother, softer complexion begin to appear. At our dermatology office, our patients love their results so much, they come back every three to four months so that they can maintain their gorgeous results.
