Welcome

Welcome to the Comfortable in Your Own Skin blog! My name is Shelley Costantini, co-founder of S4 Skincare and Esthetic Coach at 415 Spa Consulting.  I have had a lifelong passion for skin care and have helped thousands of people achieve better, healthier and more beautiful skin through my work as an Esthetician for over twenty years and through products I have developed.

In this blog, I’m going to use my experience to provide you with tips, tricks and healthy solutions for your skin care needs. I look forward to hearing from you, receiving photos and answering questions from you along the way.

Follow Shelley for advice and interactive discussions on the topics of skin, beauty and health.
