About Flirt Beauty Bar
At Flirt Beauty Bar, skincare is more than a treatment — it’s a personalized experience designed to help you look refreshed, confident, and naturally radiant at every stage of life.
Founded by licensed esthetician Sierra Kinsley, Flirt Beauty Bar was created for women who value results, expertise, and a calm, elevated environment where they can truly relax and trust they’re in good hands.
With a results-driven yet gentle approach, Sierra specializes in advanced facial treatments that focus on anti-aging, skin health, and long-term improvement, not quick fixes. Every service is customized to your skin’s unique needs, lifestyle, and goals — because no two faces (or journeys) are the same.

Sierra Kinsley
LICENSED ESTHETICIAN
With over 20 years of experience in the beauty industry, I am a licensed esthetician and 3x certified acne expert specializing in results-driven, personalized skincare. I began my career as a professional makeup artist, which gave me a deep understanding of skin from a cosmetic perspective and ultimately led me to focus on what matters most—healthy skin as the foundation of beauty.
I am especially passionate about treating pigmentation, a concern I personally experience. This firsthand insight allows me to approach each treatment with both expertise and empathy, creating thoughtful, realistic plans tailored to each client’s unique skin needs and goals.
As a solo esthetician, I am committed to providing truly individualized care—combining advanced treatments, professional skincare, and a personalized approach to deliver visible results while ensuring every client feels supported, confident, and cared for throughout their skincare journey.
I invite you to schedule a consultation and begin a customized path toward healthier, more balanced skin.
