She has performed more than 50,000 treatments in the past fifteen years of cosmetic dermatology practice.

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.

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!

I visited Dr. Austin for a skin consultation after receiving a recommendation from one of my friends who sees Dr. Austin for Botox (Xeomin) injections and to review & remove any suspicious moles/freckles and review skin damage on my neck.  Her office staff are very friendly & helpful. After washing my face (they provide makeup pad removers, facial wash & a hair band), photos were taken including one with a camera to determine sun damage. Dr. Austin has a very positive, glowing energy about her & was very easy to speak with about my skin concerns. After a full review of my skin & my skincare regimen, I got 20 units of Xeomin in my forehead & removal of a mole that was progressively getting larger on my upper lip. Thankfully the lab report indicated that it was benign. I visited again about 10 days later for additional freckle removal & treatment for sun damage on my neck, as well as a check in for my Botox injections to see how it settled in. The Botox looked great & my skin was smooth. I’ve healed up from my 2nd visit & my skin looks great.Her strongest recommendations is to always wear sunblock (I wear 2-3 layers on my face but I forgot to apply on weekdays to my neck when I was living in Hawaii which resulted in 15 years of sun damage while driving ).

This review is for Dr. Austin and her amazing staff! As a skincare professional I am very careful who I see for aesthetic procedures, and who I refer clients to. Dr. Austin is really the best of the best. She has an extremely good eye for detail and is very modest and intentional with her approach. Her treatment plan, from botox, to filler, RXs and lasers over the years has been spot on. She even knew to check my thyroid when I was experiencing hair loss. She really has my heart and I can’t say enough good things about her. Plus, her staff is so so kind, efficient and caring. I always look forward to coming to BACD for treatments, and feeling confident in the quality of care here.

As an esthetician I deeply appreciate the impecccable 5 star job this office does. Dr Austin has a reputation for being extremely careful and honest with her patients and each botox procedure I have had with her has been flawless. I also have to shout out nurse mary who is a rare gem in this industry. She makes any procedure comfortable-- even microneedling. She is so deeply personable and makes every patient feel special. The supporting staff is always so patient and caring as well... and Monica the esthetician who supports dr Austin is another absolute gem and has a fabulous bed side manner-- this office is unique in its precision with treatments and lovely people to make sure you’re always at ease.

I started seeing Dr. Welsh in my early 30’s for adult acne. She taught me proper skincare and set me up with the best products. I am checking in yearly to keep products on point with current skin changes. As I age, I need to choose to come in Every 4-6 months for botox & filler. Plus an occasional photo facial and laser hair removal treatments.  It is now 20 years later I honestly could pass for ten years younger than I am. Dr. Welch is magical, in my opinion. If you ask her a question, you are going to get an honest, educated answer. I would not trust anyone else.

Average Rating


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.
