Tiffani is AMAZING!! I got my Korean lash lift here and let me tell you my lashes were standing!! No curling was needed and not even mascara unless I wanted to make them darker. My boyfriend even said my face looks different having my lashes "naturally" stand up. They lasted about 8 weeks and felt nice not needing to do anything to them once I woke up. She was amazing always super kind and wants to make her clients feel beautiful. read more

I really can't say enough good things about Beauty Lab and its proprietor, Tiffani. I previously had gone to another highly-rated eyebrow studio in SF and found that the results didn't last and my brows were never quite even no matter how many "tweaks" I asked for. Tiffani understood exactly what I was looking for, and overdelivered. She has the eye of an artist and the rigor of a clinical practitioner (and her own brows are evidence of her work.) She also does lash curling. Plus, she's really just a joy to be around. IMO, an appointment with Tiffani followed by a little visit to Arsicault directly next door is an A+ day. read more

Quick to respond. Set up an appointment. Tiffani was so sweet and listened to my concerns. Made me feel so comfortable and results were perfect. My new go to salon for my eyebrows. Booked a lash lift appointment for the future. Can't wait! read more

I had my eyebrows done years ago somewhere else, and while they were okay, I never imagined they could look this good. I am absolutely blown away by the incredible job Tiffani at Beauty Lab did! I should have posted after my first appointment in Feb 2026 -- from the moment I walked in, she took such great care to make sure I was comfortable. She walked me through the entire process step by step, answered all my questions, and made me feel completely at ease. You can tell she genuinely cares about her clients and her craft. She is truly an artist--her attention to detail and precision are unmatched. I just had my 6-week touch-up, and I couldn't be happier with the results. My brows look natural, beautifully shaped, and better than I ever thought possible. I wholeheartedly recommend Tiffani at Beauty Lab --do yourself a favor and book with her. She's absolutely wonderful! read more

Tiffani did an incredible job on my mom's eyebrows! From the very beginning, she was so flexible and accommodating with scheduling--she worked around my mom's many medical appointments without hesitation, which we truly appreciated. During the sessions, Tiffani was extremely gentle and patient. She checked in often to make sure my mom was comfortable and not in any pain. You could tell she genuinely cared and wanted my mom to have a great experience. The results were beautiful. Everywhere we went, my mom received so many compliments on her eyebrows. She felt confident and was absolutely thrilled with how they turned out. We're so grateful to Tiffani for her professionalism, warmth, and amazing work! Highly recommend her if you're looking for someone skilled, kind, and thoughtful. Thank you, Tiffani! read more

I wish I could give more stars!! Tiffani is absolutely fantastic in every regard. I had gone to a couple of other microbladers years prior and contacted Tiffani with pictures of my faded, blurred, heavy salmon-pigmented brows, which desperately needed reviving. I also barely have brows to begin with since the hair is blonde and sparse - so not a lot of room for error with semi-permanent makeup. During our consultation, we discussed options to either dissolve and start with blank canvas or try using a different formula darker color ink. I went with the latter option to save time and have no regrets! After the initial session plus a touch up, my brows look better than they've ever looked. The best part is I had no scabbing and fast healing time with no ink loss. The finest lines and natural brows of my dreams!!! Tiffani is extremely knowledgeable about shaping, pigment, coloring, needles, healing - everything! She's also the sweetest, most welcoming and accommodating. I can't imagine anyone would be disappointed with brows by Tiffani! read more

Tiffani is fantastic. She took the time to explain everything in detail at the consultation and what to expect during the healing process. During the procedure she made sure I was comfortable throughout and checked on me each time before starting the next step. The results are fab, the convo was great, and the experience was top notch! Cant wait to book again for my touch up!!! Highly recommended!!! read more

Tiffani transformed my face! Well, maybe that's hyperbole -- but honestly, my nano'ed brows make me look 10 years younger. (I'm in my 60s.). Tiffani took such care to create brows that were like my young originals, only better. More refined, more aligned. But also so natural my husband didn't notice I'd had anything done for nearly 2 days, except that he kept repeating I looked so pretty. Tiffani is doing artisanal, personalized work here, taking your face, lifestyle, coloring and taste into account. I am so, so thrilled. I feel put together, bold, even striking in my new brows. I would recommend her to absolutely anyone -- and will. read more

The rumors are true - Tiffani is a really, really good brow artist. I've had maybe 6 or 7 brow "jobs" from different people, and and Tiffani is by far the best. I'm 63 and blonde and my eyebrows have holes in them and didn't look even remotely related to each other when I first came to Tiffani. I didn't want the "laminated" look that's so popular these days, I wanted a more natural look, with just shaping and tinting. I left there looking SO MUCH BETTER! So I saw her again and she did an even better job than the first time, which I didn't think was possible. She's personable, kind, and very talented. Do it! read more

Hands down, Tiffani is the absolute best! My mom and I both had nano brows done. Tiffani truly has a gift. The level of skill and artistry she brings to her craft is incredible. I receive endless compliments on my brows, and I couldn't be happier with the results. Highly recommend Beaty Lab to anyone looking for expert brow transformation! read more

Since Tiffani is the only person I trust with my eyebrows it was a no brainer to trust her when she suggested a hot plasma fibroblast for my face. She explained that this procedure would super charge collagen production for 6 weeks with results lasting up to 2 yrs. It's been 2 months now and I can't believe how smooth and rejuvenated my 60 yr old skin looks and feels. Sign me up to do it again! Tiffani is incredibly professional and I am confident in recommending all of her services. This girl's got game... read more

Tiffani is amazing! She is very thorough about brow aftercare which I appreciate. She does her best to give you what you want and gives her expert advice regarding color, shape, goals etc. I am very happy with my brows and will be back for a touchup soon! read more

I had been toying with the idea of getting some microblading for my eyebrows, exhausted from filling them in nearly every day for the last few decades. I did a bit of research on where to go, as well as costs. Tiffani was around the corner from me and had incredible before/after photos, which made me feel super comfortable in booking a consultation. My consultation with Tiffani was like spending time with a friend who specializes in brows. After some discussion of what I was looking for, Tiffani recommended nanoblading - better looking and lower margin of error/scarring? I'm in! She did some brow mapping and we worked together on what it could look like. She provided great information on how I would need to prepare prior to the appointment (which I didn't book at the time), and gave me her phone number in case her available appointments didn't work for my schedule. After a few weeks, I was able to find the time and I booked on a Friday for Monday. She texted me more details on the preparation I needed (retinol use, caffeine/alcohol intake), and answered my questions. When I got to Beauty Lab for my appointment, we went over the risks associated (as with any procedure) to make sure I was ok with it, and then did an even more detailed brow map. I asked for a few changes, and we picked a color together. She used a topical numbing cream for the first round. I did feel the work she was doing, but it was tolerable. Halfway through she put on more, and then I couldn't feel anything. In total I was there for just over two hours, and she sent me home with a kit and instructions to take care of the healing process. Overall a really stellar experience that I would absolutely recommend. I look forward to when they're fully healed, and booking touch up appointments! read more

Tiffany is unbelievably FANTASTIC!! My eyebrows looked so much like I just got them threaded and tinted. Soooo natural! So many compliments! Check her out soon and make your appointment! read more

Tiffani is the sweetest and most comfortable person I've gone to for beauty needs. Any requests or modifications on beauty service, whether I wanted the brows lighter that what I wanted or even redoing the shape entirely of the brow tint, she is so kind and assisting in achieving what I wanted. She is also very easy to talk to and even if you don't feel like talking, she just goes on with her work flawlessly. I have literally fallen asleep getting my lashes lifted and woke up to them being amazing and she is also very knowledgeable in all she does. 10/10 would recommend her services! read more

Tiffani is amazing. She is extremely thorough and meticulous with her approach. She is patient and kind taking the time to understand her clients needs and ensuring that she gets it 100% right. read more

Tiffani combines care, artistry, skill and professionalism seamlessly. As an older woman, I didn't think I could have brows that looked beautiful and natural. Tiffani listened to what I wanted and took the time and care to give me an amazing new look. As you age don't underestimate the difference that having well defined eyebrows can make in brightening and opening the face. It definitely did that for me. I highly recommend Tiffani as a Brow Artist. Last thing. Other beauty care professionals I see, hair, nail etc - say that my brows are the best example of Nano Brow artistry they have seen. They asked for Tiffani's contact info to refer to clients and to make their own appointments. Thank you Tiffani! read more

So I found this place online and of course I was a bit skeptical because it's the internet. But after looking at her work on her professional Instagram I felt confident this was the right place. Tiffani was so sweet and made me feel very comfortable during the process. After taking her time to thoroughly go over the different techniques of micro blading, nano, and different types of shading. I chose to go with nano ombre powder finish look I believe is what it's called lol. I showed her a picture of how I wanted my brows based on a picture when I had my makeup done for a past birthday. (included in the pictures) I'm really happy with the way it turned out. Although she explained the healing process is different for everyone she mentioned it would lighten up a bit and she recommended a touch up in the near future. So stay tuned because I will post my eyebrows before and after the touch up in 8 weeks! Lastly I just wanted to say her customer service level is at 1000! She provided bottle water,a healthy snack (the process takes a while about 4-5 hours from consultation till end. I told she's thorough!) she had Ac and a throw if you get cold! The music was great and the conversation was very pleasant. She even gave me an after care package with all that I needed for the healing process along with instructions for after care. I recommend this place to anyone looking to enhance their natural beauty or wanting to change their look and is expecting to get a high level of care and customer service. My friends are really impressed with the results and are asking about making an appt. so I thought I would share this review for all to read. Thanks again Tiffani! read more

Tiffani is exceptional. A brow perfectionist (and you want that!) I came out with beautifully arched brows that enhanced my eyes and highlighted my face. Tiffani's disposition is a breath of gray air and her kindness and focus is unparalleled. Visit her! read more

I had my brows microbladed several years ago. The overall experience was mediocre, so I was hesitant to go back to the same place. After stalking Tiffani online, I finally reached out to her to inquire more about her techniques. She was super attentive to my needs and made me feel super comfortable so I booked right away. Thank goodness I did! Tiffani is an absolute artist. I love my brows and will continue to go back to her for touch ups as I feel she customized my treatment to perfection! 100% recommend! Thanks Tiffani! read more

I am so incredibly happy with my brows by Tiffani! I've had my brows done in the past one time and I let it fade because I wasn't satisfied with it. Because of this, I was very particular about how I wanted my brows to be. Brow Mapping: Tiffani's very first take at brow mapping me was basically done just with minor adjustments that I was being very particular about. In my previous experience this took a couple times. Tiffani was extremely patient with me and my requests and took the time to explain the pros and cons to some of my questions. Nano Brow: I love the color of my brows and her tattoo strokes look so natural! The initial outline of the tattoo hurt a bit but then numbing cream was used to fill the brow in was painless. Tiffani walks you through the process so you know what to expect. Timing: Total mapping and tattoo took around 4-5 hours, which felt like it flew by. Tiffani made sure all my questions were answered and made this experience as comfortable as possible. Post-care: Tiffani supplies you with post-care instructions and all the supplies you need. Including the shower visor that you stick on your forehead! Never seen this before haha! Location/Offices: Beauty Lab is located in the downtown of San Rafael. Easily located near food if you need to fuel up prior or after the appointment. There are parking lots around the area but if you can find it, there's no time limit residential parking a few blocks away. Beauty Lab is a single-patient room that is very clean and new. Overall, I highly recommend Beauty Lab by Tiffani. I love the shape and color of my brows and I am so excited to walk out of the house without having to do my brows every single day! I'll absolutely be going back to Tiffani for any of my touch ups! Thank you, Tiffani! read more

Tiffany is a wonder at microblading my brows. I have sent friends to her because the end results were fantastic! My brows look perfect and so natural noone can tell they are tattooed! I highly recommend her if you want perfect, natural looking brows that last for years! Thank you, Tiffany! read more

She absolutely nailed it! Not only did I get new eyebrows, I almost got a new face. Would 100% recommend

Do yourself this kindness and book with Tiffani. Tiffani is an artist on a different level. I've had microblading done before but the results have always faded so quickly, I just resigned myself to filling my brows in every day. It had been several years and I thought to maybe try again. So I start looking and nano brows pop up. And so of course, Tiffani pops up. I could not be more pleased with the results! Her warmth and kindness combined with her skill and professionalism makes for an incredible experience and outcome. Thank you so much, Tiffani! read more

Tiffani is great! I'm a lash artist and I'm very picky about the service :) You will feel very welcomed by her and comfortable to tell her what you want. She is very easy and warm to communicate. I feel very lucky I found her! I was super nervous to do this but I'm very happy that I did! Thank you Tiffani! You made my experience so positive! read more

Tiffani is a joy to work with. She's professional, friendly, patient, and detail oriented. I am so in love with my healed brows and constantly get compliments about them all the time as well. The entire process has been pretty seamless. I was able to book my first appointment as well as my touch up appointment very easily. I also appreciate that she works on the weekend and has flexibility in her scheduling. She is very thorough with her work and made sure I was 100% happy with the shape, thickness and overall look before she started tattooing. She made sure to prepare me mentally every step of the way about what to expect and wanted to make sure I was well taken care of. I would 10/10 recommend her! read more

Tiffani is amazing! I came in with mostly faded microblading from a few years ago hoping to get nano brows! Other places charged hundreds more as this was considered "corrective work", but Tiffani saw my brows and accommodated by simply booking this as a first time microblading service. She took the time to make sure that everything was perfect, from the mapping to the color to the shape in the end! I went back in for a touch up after my initial appointment, and when one of my eyebrow tails healed still a bit too light for my liking, Tiffani scheduled another touch-up session with me so that my brows would be perfect! Great experience, would book again! read more

First time getting a "Lash Lift" and I was a bit nervous but Tiff made me feel calm and relaxed and I knew I was in good hands. I LOVE my lashes and how natural it looks, makes me feel extra girly. It looks super cute. I highly recommend working with Tiffani read more

Beauty Lab - First time getting a "Lash Lift" By Tiff - Eyebrow Services Near Me - San Francisco , California

Tiffani was amazing and I love my eyebrows. What I observed about her work was impressive; the length of time she took in preparing. She drew angles and determined width and height of Eyebrows. It took about 45 minutes or more to get the correct symmetry and to make sure it was suitable to my Face. I felt no pain, and the after care instructions and package were brilliant. I would highly recommend Beauty Lab, very very professional. read more

I have been seeing Tiffani for a few years now for nano brows. She is very knowledgeable. I recommended her to all my friends, and they loved her work. Plus, she is a wonderful person to talk to. Highly recommended read more

I've always wanted to get my brows nano bladed but never found the right artist. I started following Tiffani's journey on Instagram and loved her work and decided to go for it...and I am so happy I did! :) Absolutely enjoyed my first nano brow experience at Beauty Lab! Tiffani took her time to walk me through the entire process and answered all of my questions (and I had tons). By the time we started the brow mapping and tattoo process, I felt less nervous, more comfortable and excited for my new brows! She was extremely patient and thorough during the brow mapping process as well. I was specific and particular about the shape and size and I never felt rushed or pressured. She even said "I am not going to start the tattoo process until you are100% happy and satisfied with the shape". Once we started the nano brow process, I closed my eyes, listened to some music, and relaxed. Because Tiffani had walked me through the process I knew exactly what to expect and let her do her magic! During the reveal process, I was so happy with the results!! Overall, really enjoyed my experience and highly recommend going through this experience with Tiffani. So grateful that she created such a safe environment for me! read more

I was looking for a good place in Marin to do my brows. I found lots of great testimonials about Tiffani and BeautyLab and decided to give her a try. I have just completed my one month touch up.

She has a kind and supportive demeanor and she is conscientious and does a great job. Highly recommend. read more

Tiffini not only has an amazing artistic vision as to what color and shape will look best on you, but she is precise and careful about executing it. In addition, she is very much a collaborator with you. So you don't feel like she is imposing her vision on you. It's with you. My brows look so amazing people stop me and ask me about them. And several friends are now making appointments with her. If I could give her 10 stars, I would! read more

Tiffani was absolutely amazing! She was so attentive and patient when working with me and my virgin eyebrows. I had never had my eyebrows done in any capacity and did not know what exactly to expect. Tiffani walked me through the entire process from prep, consultation, and post-procedural care. I have received so many compliments on my full, elegant eyebrows since my visit with Tiffani! I highly recommend! read more

Tiffani is a master of her craft and I highly recommend. You will love her attention to detail and ability to map out the right brow shape and shade for your specific look. The nano brow technique is my favorite. I struggled with creating symmetrical brows where my hair was missing. Now I wake up with natural looking and perfectly even brows. Just make sure you follow the directions for healing as closely as you can for the best result. Thank you!! read more

Tiffani was amazing! This was my first time getting any type of work done to my brows and I am so happy I trusted Tiffani with them! I was so nervous to get any work done, but Tiffani was so attentive and caring throughout the whole process! We talked through the shape/outline, after the procedure started, she made sure I was comfortable the whole time, was always very courteous and asked if I needed anything. After the procedure she made sure I understood the aftercare and let me know I could reach out to her anytime if I had questions. Now I always let me friends and family know that I got my brows done and it was done by someone amazing read more
