I found Mary Kay through a review of her services on Rod Sicker's yelp page (she worked there years ago before she started her own business).
Her facials are great, and she uses wonderful products (Eminence). She is very conscious of your concerns/skin care goals and tailors her services to your particular needs. She also does a full complement of waxing services. Her eyebrow shaping services are the most exacting and consistent I have ever had.
I was previously employees in the spa industry, and have worked in two of the top-rated destination spas in the country. Mary Kay's service matches or exceeds the experiences I have had at those spas, without the fancy-spa price. She is very professional, and returns phone calls promptly. She also accepts online reservations.
Highly recommended. So glad to have her in C-U.
