JACQUELINE GUELLI
Founder of JAX SKINCARE

Founded in 2017 in Boston, JAX SKINCARE was created by Jacqueline Guelli, a licensed esthetician and makeup artist with over a decade of experience working closely with skin.

Dissatisfied with what was available on the market, Jacqueline began formulating her own blend in her kitchen, carefully testing and refining a combination of antibacterial and anti-aging oils. The brand began with a single, transformative product: the balance oil, (now known as THE OIL) a multi-functional product that quickly became a client favorite and remains the hero of the brand today.

As JAX SKINCARE evolved, Jacqueline expanded the line into a curated collection of skincare essentials designed to support a simple yet powerful routine. This philosophy—less is more—is the foundation of the brand.

Building on her background in makeup artistry and her belief that great makeup starts with great skin, Jacqueline later introduced MADAME JACQUELINE BEAUTY—a refined makeup line designed to complement the JAX SKINCARE philosophy. The makeup collection focuses on elevated essentials that enhance natural beauty, prioritize skin-loving formulas, and embody timeless sophistication.

Both brands are united by a shared aesthetic and ethos: intentional formulations, clean and sophisticated packaging, and a minimalist approach to beauty and lifestyle.
