Reviews highlight positive experiences with facials, massages, haircuts, pedicures, and B12 injections, noting that practitioners take time to address specific skin concerns and preferences.

First time at this adorable salon today. A hidden gem right by the O’Fallon Public Library. I was impressed with all the offerings.

I’ve had such a lovely massage experience with Michelle at Southern Serenity! She pays attention to every tiny detail, and it’s so clear she cares very much about helping others. It’s truly the most magical, healing massage I’ve ever had.

Only been here for maybe a month, but there's great service here. There's great people here, such as Shelly and her mom, they're awesome people. And the inside decorations are beautiful! Plus snacks. Great place, great people.😁

I had my first facial last week with Jeannie Smith and she was WONDERFUL! She thoroughly explained the entire process and ensured that I would reap full benefits of the facial with my hormonal acne. It was so relaxing and my skin has a significant noticeable difference. She strives to pamper with including massages on your arms, hands, and feet! Following my facial I got a mani-pedi with Astra which had been equally as relaxing!! Astra was so sweet and made me so comfortable the entirety of my appointment. Will definitely be back to book with both ladies!! ❤️

I booked my very first Facial with Jeannie Smith. I have very sensitive skin and rosacea and she looked at my skin and created a specific facial for me, which included and hand and foot massage ending with a red light therapy. The products she said were top notch and I left there feeling and looking great! Book your next facial with her, money well spent!

Absolutely Beautiful establishment! If pampering you want, that is exactly what you get.
Received my first facial. I scheduled it with Jeannie S and was forever changed. Outstanding!!! I will see her evey month now.
I also get my hair done with Shelley O. Literally one stop for all the self care pampering you need.
