Clean Beauty. Wellness. Nontoxic Living.

I spend an unreasonable amount of time researching ingredients, testing products, and finding things that are both nontoxic and actually good. Because what's the point of a cleaner swap if it doesn't work? Everything I share has to meet my standards for both ingredients and performance.

A note from Catherine

Welcome to my little corner of the internet. I test everything so you do not have to and share the products that actually pass the ingredient and performance test. Think nontoxic swaps, skincare that truly works, and honest reviews you can trust. If you love learning what is really in your products, you are in the right place.

xx, Catherine

The short story

I did not take the direct route into beauty. I studied finance and spent my college years working the floor at Sephora, then went into M&A and supply chain consulting. The industry changed a few times. The obsession did not.

Shelter Skin began after I was officially diagnosed with PCOS. I went looking for bodycare that was truly clean and still beautiful to use, clean ingredients, beautiful packaging, and formulas that actually smelled good, and I could not find it. So I made it.

The Nontoxic Tea is where all of my clean product recommendations live in one place, with the ingredient detail and honest context that a 90 second reel never has room for.
