Injections were perfect - no bruises and very natural looking
Everything about my experience with Dr Maas qualifies for the 5star rating. The office is comfortable, the staff are professional and Dr Maas is an expert in the field. The Botox injections were perfect - no bruises and very natural looking. As an incentive for posting a review, this reviewer received an entry into RealSelf’s monthly $500 gift card giveaway.
Getting DeepFX for Deep Acne Scars (30F)
I feel like I tried everything under the sun to try and resolve my long-standing acne scars. I’ve done the e matrix laser, aggressive pixel lasering, and I’ve done a bunch of clear and brilliant. Since meeting Dr Maas, I realize that Deep and Active is the way to go. During the procedure he marks individual scars he wants to focus on and uses the laser to pull down the shoulders of bathtub scars so they become less visible. I love that he’s so scientific and also offers a lot

The BEST
1997 is the first time I had a procedure done by Dr. Maas. As an esthetician and RN, it doesn't get any better than Dr. Maas. He has maintained his integrity, treats every visit like the first time, he has an integrity and code that has not lessened or weakened. He is a superstar in his field and a dedicated researcher.
An Excellent Skilled and Compassionate Dr.
Dr Maas is one of the most compassionate and skilled cosmetic surgeons I’ve ever been to. His attention to detail and natural aesthetic combined with decades of experience helps address any concerns. I couldn’t help but read the negative reviews m, and after carefully reading these patients on other websites have posted other cosmetic procedures not done by Dt. Maas and their unhappiness. This leads me to believe that there will be those with unrealistic expectations that you
The Most Phenomenal Surgeon
I am a mega fan of Dr. Cory Mass! He’s been my aesthetic doctor for over a decade, and just recently I had upper and lower eye lid surgery. The outcome is phenomenal ~ I am overwhelmed with happiness about my results! In my mind, there is no more capable or skillful doctor, he exceeds my expectations EVERY TIME- He is a master at his craft, bringing out natural beauty through clinical and surgical technique.

Botox injections into parotid and submandibular gland enlargement.
I was diagnosed with Sjögren’s syndrome in 2014 mostly because of jaw pain and swelling of my salivary glands. I was trying to treat them the best I could with massage and heat but nothing was improving. I would only see improvements if I took a taper does of prednisone , but that was something I couldn’t take long term. I remembered Dr Corey Maas telling me that Botox in the salivary glands can shrink them. Fast forward to May 2018 & I finally go in to get them done. By this

Dr. Maas and Fillers.... - San Francisco, CA
I have a couple of very fine lines on the left side of my face. Dr. Maas filled them for me - in a way that you cannot tell that it was done. It is PERFECT, doesn't look different than the other side of my face, isn't puffy, bulgy, etc. It is so perfect - looks completely natural and no one can tell that it was done on the left side of my face. He is so excellent!
Not Worth It

i was SO excited when i heard about kybella. there is a plastic surgeon in the building where i work and i asked him about a neck lift or face lift or something for my gross double chin and he told me to wait a few months because a new drug was coming out that would dissolve fat. i waited and did my research on the different doctors that would offer it. i decided not to go with that particular doctor because i found someone who had worked on the clinical trials. so i made an

Master of Botox - 26 Year Old Female. San Francisco, CA
Dr. Maas injected botox into my forehead area and I was extremely pleased with the results! My forehead looked very natural afterwards and that is exactly what I was hoping for. I was numbed up prior to the procedure and there was no pain during the injection. I am so excited for my next appointment! Dr. Maas is the best!
