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.

I have been seeing Dr. Austin for 4 years now. I initially saw her when I was experiencing some difficult to treat acne in my early 20s. She listened to my concerns and really educated me on proper skin care. Since then she has continued to help provide new products/recommendations based on my needs at that time. I have also been seeing her for filler and botox treatments for the past two years. She has always listened to what I wanted and given me incredible results. She keeps things natural and really has an amazing eye for the face and facial structure. Beyond her work, she is a really incredible doctor. Her bedside manner is unparalleled and she is always evidence based in her practice. She is a beautiful person who works hard to help others feel beautiful. 11/10 would recommend.

I want to give an amazing shout out to Cynthia! She is hands-down, the best Botox administrator I have ever worked with. She is professional, on point, and truly listens to her patients. I wouldn’t go see anyone else. Cynthia rocks!

Dr Austin took my decent mid-50's skin and flagging self-esteem and made them really, really great. She flawlessly filled old acne scars, removed pre-cancer bits and rosacea, smoothed wrinkles, snatched up my jawline and explained how anatomy and biochem work during my visits. She's made a long-term plan for me and all her patients that seem like the minimum of highly effective things, so we all look startlingly better but still believable and healthy. Dr Austin is gentle, rational and super trustworthy. She's like a wizard. Her team is awesome, too.

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.
