Testimonials

I’ve been seeing Kat for Botox for nearly 10 years, and she is truly the best. She’s highly knowledgeable and experienced, always thorough, and takes the time to explain what she’s doing so I feel completely at ease. I’ve gone to others over the years, and none compare to the quality of care or the natural results I consistently get with her. On top of that, her office is beautiful and welcoming. I trust Kat completely and wouldn’t go anywhere else.

I had an amazing experience at Muguet Med Spa in Newport Beach. From the moment I walked in, the team made me feel welcome and comfortable. I met with Kat, RN, who is an expert in medical aesthetics. She listened carefully to my concerns and created a customized treatment plan that included Botox, Juvederm fillers, PRX-T33 skin treatment, and facial contouring. The results are natural, safe, and better than I expected. The entire staff at Muguet Aesthetics & Medspa is professional, knowledgeable, and caring. They focus on patient safety, honest recommendations, and achieving great results. If you’re looking for the best med spa in Newport Beach for Botox, fillers, or facial rejuvenation, I highly recommend Muguet Med Spa.

I had the absolute pleasure of seeing Kat. From the moment I walked in, everyone at M’uguet Aesthetics made me feel welcomed, comfortable, and completely cared for. ( thank you Alice ) Not only is Kat incredibly skilled, she also has a calming and kind energy that instantly puts you at ease. The micro-needling treatment was wonderful, she even put me under red-light therapy before I left to increase the benefits of my treatment. Her recommendations are thoughtful and tailored specifically to my skin - she truly cares about her clients’ long-term results. If you’re looking for someone who is both talented and genuinely passionate about helping people look and feel their best, Kat is the one. She’s a true gem, and I feel so lucky to have found her!
