Frown Lines (the 11s)
A smoother brow that still moves.
The two vertical lines between your brows come from a muscle that pulls them together every time you concentrate or squint. Relaxing that muscle softens the lines.
- 15 to 30 minutes
- Nothing that stops you going back to work
- Full effect in 7 to 14 days
Does any of this sound familiar?
You are told you look cross when you are concentrating.
The two lines show in photographs before anything else.
You have started holding your forehead still on purpose.
Why they happen
One muscle between your brows fires when you focus or squint. After years of it the skin above creases in the same two places, and eventually the lines stay when your face is still.
How Dr. Mauer treats it
The main treatment
Botox & Neuromodulators
A few units into the muscle doing the pulling. He leaves the muscles around it alone, which is why his patients say they can still move their face.

Dermal Fillers
Only if the crease still shows once the muscle is relaxed. A very small amount, and never a first step.

I will try to make this short and sweet. I was referred to DR.Mauer by my aesthetician in 2020. Full face thread lift was recommended so I complied. Roxanne kept telling me it would keep getting better with time and this is exactly what happened. Now 2026 it was time to return. Thinking I would need to do a full face of threads again, DR. Mauer suggested volume for my face to get the skin plumper from the fascia.Fascia is like the girdle that…
Dr. Mauer is truly exceptional — not just a doctor, but a true facial artist. I’ve had Botox and fillers with him, and the results were incredibly natural and beautiful. He took at least ten years off my appearance while still making me look like myself, only refreshed and more confident. What sets Dr. Mauer apart is how deeply he cares about his patients. He takes the time to listen to every concern, explains everything with patience and…

I have been a client of Dr. Adam for over 10 years. He has an amazing assistants named Roxanne and Alanna and I have always walked away feeling great. He listens to what it is I want and advises me on what's best for me. I feel heard and respected. Just got some work done on my eyes and neck- Botox. As usual and instructed, it took a few days for the injections to start working but when they did, it looked AMAZING! I have been his client for over…
I’ve been going to Dr Mauer for 4 years and as a physician also who absolutely INSISTS on looking natural and still recognizable, I could not recommend him enough. After 4 years of thread lifts, years of Botox and fillers, I will never trust anyone else. His techniques are unique. He does PDL threads via a deep cannula technique, vs the nonsense PDO fox eyes and lifts I’ve seen done on tik tok. His Botox is unique, and selected specific to each…

( Unlike others who do the frozen look) Dr Mauer does beautifully balanced Botox I love that I can move my eyebrows! and no one knows why I “look great” ….no wonder he came in First in competition for Best in America
I have seen Dr. Mauer for years, for some non invasive treatments that are unbelievable and amazing. Adam's perfect balance botox treatment and facial fillers sessions are phenomenal. He is caring and will take his time to explain, make you comfortable and make your experience as as pain-free as possible. The results are always great! He is a passionate dr artist 🎨 indeed. You will not regret the experience.
Dr. Mauer has been my doctor for 18 years, and I look better now than I did at 30. His natural transformations on my face are so subtle that no one ever suspects I’ve had any procedures. He genuinely cares about his craft and takes the time to understand each patient’s needs. His bedside manner and expertise are impeccable. He never pressures you into having unnecessary procedures. I highly recommend him, and I’ve sent him patients who have…
I have been seeing Dr. Mauer for face and neck enhancements since 2009. I have always been very happy with the results of his work in maintaining a youthful and natural appearance. On occasion, I would try other Professionals and come away disappointed. In my opinion, no one comes close to Dr. Mauer's expertise and mastery. Over the many years of his research and experience, Dr. Mauer, (With the wonderful help of his assistant Roxanne), has…

Questions about frown lines
How many units will I need?+
It depends on how strong that muscle is, so nobody can quote you a number before seeing your face move. Dr. Mauer works from how your face actually behaves, and it is usually less than people expect.
Will my eyebrows drop?+
That is what happens when the wrong muscle is treated, or too much of it. It is the specific risk that experience prevents. Have it done by a physician who does it every day.
Can I start before I have lines?+
Some people do, once the line has started appearing on movement but before it has set into the skin. Whether that makes sense for you is a consultation question, not a rule.
Will people be able to tell?+
The point is that they cannot. The lines soften and your expression stays yours.
