Client Testimonials

“I had the pleasure of receiving a Hydrafacial from Ewa. As a dark-skinned woman with sensitive skin, I’ve been hesitant about facials due to a previous bad experience. However, Ewa completely changed my perspective. She took the time to understand my skin, made a treatment plan and recommended products specifically for my skin type. This Hydrafacial left my skin feeling fresh and looking smooth. I’m genuinely impressed and can’t wait for my next appointment!”
