Meet the Team
Karen Desteuben
Owner, Lead Esthetician
Karen brings over 15 years of experience in the beauty and personal care industry as a licensed esthetician, instructor, nail technician, and Reiki practitioner. Her career began at an advanced training institute for licensed professionals, where she worked closely with salon and spa owners—providing professional-grade skin care, advanced equipment, and continuing education classes designed to help businesses grow and thrive.
After earning her esthetics instructor license in 2014, Karen went on to teach advanced theory and in-depth product knowledge. She found deep fulfillment in mentoring professionals and supporting them as they expanded their skills and confidence behind the treatment table.
Alongside teaching, Karen spent years working hands-on in busy salons and spas, where she built a loyal clientele and honed her craft in a fast-paced, full-service environment. This blend of education and real-world experience shaped her thoughtful, results-driven approach to skin care.
In 2020, Karen returned to teaching—this time in an undergraduate program—where she discovered a renewed passion for education and experienced even greater professional growth.
In March 2021, Karen opened Moonstone Beauty Studio, a reflection of her commitment to high-quality, personalized skin care experiences. Today, she continues to combine advanced knowledge with intuitive care, offering treatments that are both effective and deeply relaxing.
Her favorite service to perform is Brow Sculpting, where precision, balance, and artistry come together to enhance each client’s natural beauty.
