Dana Riccio

Medical Aesthetician


I've had the pleasure of working with Myskin Services since 2014 collaborating directly with Marichelle to develop and customize skin care protocols. I work closely with clients, preparing the skin and treating ongoing conditions prior to each patient's cosmetic procedure. Using physician-dispensed cosmeceuticals in conjunction with personalized facials and peelsheal practices, I ensure that our MySkin patients leave our spa with nourished skin that immediately radiates natural-looking beauty and youthfulness.
