Our Resident Facialist

Sarah Iveson, LE

Sarah is a natural and non-toxic beauty pioneer in addition to having one of the most soothing spirits we know. She first became fascinated with holistic approaches to skincare when she trained in depth at a holistic pharmacy with highly regarded European health and beauty brands in the early 2000s — long before natural beauty was the broader force that it is now.

Sarah became a licensed esthetician in 2007 and soon became known for her stellar facial treatments and relaxing facial massage techniques at a celebrity makeup artist studio in San Francisco. We speak from experience when we say that her glow-inducing oxygen facials are reason enough to book repeat visits, but she’s also such fun to hang out with that it’s hard to leave our cozy room when your treatment is over. She also constantly astounds us with her depth of knowledge of all things skincare.
In her free time, Sarah dabbles in photography and floral design — hobbies that enhance her knack for esthetics and her ability to pick not only the most effective skincare products for your specific concerns, but also what might be the perfect lipstick shade for your date night. 

Sarah is available for facials at Ayla on Fridays and Saturdays.
