Octocrylene — Yes, a 2019 study showed some thyroid noise in rats. The highest dose with no harmful effects was equivalent to a 175-pound man eating (not wearing) two full bottles worth of Morning Rub. And not just once. Daily. Don't feel like eating your sunscreen? Your skin absorbs about 0.33% of what you apply. At that rate, you'd need to slather on full-body sunscreen over 1,000 times a day to come close. We'll wait while you do the math. The FDA, EU, Australia, Canada and every major regulatory body on the planet have all reviewed the data and still believe octocrylene is safe at regulated levels.
 

BHT — An antioxidant that keeps our formula stable and effective. Same story as octocrylene: flagged by Yuka for effects you'd never see in real life. Even at the highest allowable concentration of 0.5% (we use a fraction of that), you'd still be 267x below the threshold that raised flags in studies. It's in thousands of cosmetic formulations globally and has been for decades — not because no one checked, but because everyone did.

Phenoxyethanol — The most common preservative in leave-on skincare products, standing between you and a jar full of bacteria. We use it well within regulatory limits. The alternative is skipping it entirely, which sounds "clean" — just don't come crying when your moisturizer starts growing its own ecosystem.

Safety data drawn from published toxicological studies and global regulatory assessments (FDA, SCCS). We stand behind our formulas — but skin is personal. Patch test and consult your dermatologist with any concerns.
