Sarah Dorsainville

Ever since watching my single mother take time out of her busy week to just stop and do some self-care, it dawned on me that stopping to take care of yourself, which is essentially showing yourself, love, can help you mentally conquer your next challenges.

I started my career in 2001 in the world of makeup and had the privilege of building a business by helping brides feel the epitome of themselves on their wedding day. In 2012, I started in the lash industry adding this service to offer something that had more lasting results to my clientele. Discovering then a new passion, I started to multiply training, learning everything I could about lash artistry. My journey led me to then become a training director for two of the biggest lash companies to date.

While holding those titles, I also added permanent makeup to my belt. Starting with microblading, I quickly saw the appeal of permanent makeup through machine use which was more lasting and less traumatizing for my client’s skin.

Today, I offer a wide array of safe lasting treatments to my clients in hopes to enhance their natural beauty so they can continue to feel their best.
