Jenny did an amazing job on my eyebrows! It was my first time getting microblading done. Her treatment room feels like a spa and she is so attentive to how comfortable you are. I love how my eyebrows turned out and I am so grateful for Jenny! Will definitely come back and would highly recommend her.

After first facial

Jenny is great! Got my eyebrows microbladed with her. I love the shape and I've gotten many compliments regarding my brows. It does start a bit dark, but it's now faded to a very natural shade. It is a bit painful so I recommend going off-period times to minimize pain and bleeding. Her place is super clean and zen and she even provides eyebrow visors for after, so when you shower it doesn't get wet. I went back to her to do the Korean 12-step facial and my skin is already looking much more plump. I got a 6 pack session bundle, so will be back to remove my blackheads and start some skin brightening!

Jenny did a good job on my eyebrows! I love it :)

Jenny did a good job on my eyebrows! I love it :). The place was clean too and gives a very relaxing vibe. Price is reasonable too. I wanna try the Korean facial next.

Happy customer post first micro blading round! I love them

This was my first time doing something cosmetic to my face. I did research on yelp and Google, and watched YouTube videos before coming across Jenny and brow + K beauty lab. I paid my deposit. I visited Jenny and her office in Castro Valley. It was a very clean and relaxing environment. Jenny was very meticulous, organized and thoughtful while micro blading. As a result, I felt very confident in Jenny's abilities. Overall, I had a fantastic experience and love my eyebrows. I will be a repeat customer.

Very satisfied!!

Jenny did an amazing job on my eyebrows. This is after my 6 week touch up, I am in love. I had little to no brows from over tweezing, and she brought them back to life. I was skeptical at first because this is semi-permanant makeup. But, after reading the reviews here, i took a chance and am so happy I did. She is so sweet, and her shop is very beautiful and relaxing. She makes you feel very comfortable. If you are debating on going to her to get microblading, DONT!!! Make an appointment, you will be very satisfied.

Glass Skin

Jenny has been my go-to for microblading my brows for years. However I just recently discovered she also does Korean facials. I have only gone for facial twice and my skin is starting to have the glass effect (like all the Korean ladies). In the pic I am not even wearing makeups. I am so happy I bought a package of 5 facials.

Glowing after a 10 step Korean facial. Thanks Jenny!

I just got a 10 step Korean facial from Jenny and absolutely loved it. She brought my dull and dry skin to life and got it glowing again. The studio is very clean and calming. I highly recommend getting a facial with Jenny!

The day after my first time microblading. They look natural and the shape is perfect. I got so many compliments!
Jennifer C.

The first time I ever got microblading was here with Jenny (owner) and that was back in November, 2022. More than 1.5 year later I am coming in for a touch-up. Not because it faded but because I wanted to stay on top of it. I'm sure I could've gone 6 more months before needing a touch up. I will only go to her and her pricing is fair and reasonable. She is so good at what she does and I love my outcome every time! She makes sure you are comfortable and relaxed. Her space is so clean and that is a MUST for me. She also keeps the room at a cozy temperature. I even fell asleep while waiting for the numbing cream to do its magic. Plus she is a sweet lady and that's another +++ for why I will only come to her!

Waited to write this review until my brows were "set" after 2nd session and 1 week after healing. I love my brows. Jenny took her time and provided quality service. Just know that the procedure is slightly uncomfortable and that numbing cream is not 100%. You will need to squeeze that ball she gives you.. Overall happy with results. Just know it's super dark the first week after the session but it normalizes the week after. "Trust the process "

Today I had the appointment for microblading eyebrows service at 12:30pm. The appointment was made on line and she immediately sent me a confirmation text. Jenny is amazingly beautiful and kind. I was s little worried about what my eyebrows were going to turn out. She let me express my expectation to her and adjusted the shapes so many times until I was satisfied. I was so embarrassed to be so picky but she was absolutely patient and professional. She also assured me not to worry about today's treatment. The second part of touch up will be the final look. Thank you Jenny! I am looking forward to seeing you in six weeks for the touch up!

See all
