Our Wellness Lounge

It began with two sisters passionate about delivering high-touch, results-driven, and non-invasive treatments powered by skincare lines rooted in ethical practices and high-performance ingredients. From that vision, Napa Valley Collective was born.

Whether you’re seeking advanced acne care, age management, or integrative skin health guidance, our Wellness Lounge provides a curated experience designed to rejuvenate and restore.

Book with Cynthia

  • "First time getting a Hydra facial and the experience blew me away. Walking in the environment it is warm, cozy and inviting. Cynthia does an amazing job explaining every product and every step she uses throughout the treatment. I’ve truly never seen my face glow like it did after my facial. Highly recommend. It’s been a couple of days since my Hydrafacial and my skin is still glowing."

    “The review is long overdue; I've been seeing Cynthia for 2 years now. I can't thank her enough for what she's done for my skin. I first developed acne in 2021, and I was uncomfortable with my skin at the time. Nothing was working for me at the time. Cynthia was able to evaluate my skin, provide recommendations, and make changes in my regime to treat my acne..."
