Built by someone who needed it. Carried forward by someone who grew up with it.
Nopsor began in 1999 in Querétaro, Mexico — not in a lab, but in a home, by a man who had run out of options for his own psoriasis. Twenty-seven years later, that same formula is now available in the United States.
A formula born from frustration — and determination.
José Luis Aguilar Sánchez spent decades living with severe psoriasis. He tried everything available — cortisone injections, steroid creams, UV therapies — and nothing worked. The condition wasn't just physical. It followed him into every room, every handshake, every interaction.
In 1999, frustrated and out of options, he began experimenting himself. Working from his home in Querétaro, Mexico, he tested combinations of clinically proven active ingredients — coal tar, salicylic acid — alongside a proprietary blend of eight herbs he had researched for their skin-calming properties. The formula that emerged worked for him. Then for his neighbors. Then for anyone who asked.
He never set out to build a company. He set out to solve a problem. What started as rows of hand-labeled bottles on a dining room table became a formula trusted across Mexico for over 27 years.
I didn't build Nopsor to sell a product. I built it because I needed it — and because I knew others did too.

The formula never changed. The presentation evolved.
From hand-labeled bottles in a Querétaro home to FDA OTC-compliant packaging in the United States — the active ingredients, the herbal blend, and the nightly routine have remained exactly the same since 1999.

A son carries his father's work to the United States.
Ernesto Aguilar grew up watching his father build Nopsor from nothing. He also grew up with psoriasis himself — diagnosed around 2014, though the symptoms started in childhood. He knows firsthand what it means to live with the condition, and what it means to find something that actually works.
After a 35-year career at Hewlett-Packard and then HP Inc., Ernesto stepped away in February 1st, 2025 to become CEO of Nopsor USA full-time. His goal was straightforward: bring his father's formula to people in the United States who need it, with the same care and honesty that has defined the brand for 27 years.
Nopsor USA launched on Amazon and at nopsor-usa.com. Every bottle ships from Texas. Every formula is made to the same specification José Luis developed in 1999.
