In the U.S., only 11 cosmetic ingredients are banned by the FDA. The Periidot No List is a refined collection of 400+ harmful ingredients you’ll never find at Periidot, carefully selected based on both scientific data and real-world usage. This curated list zeroes in on the ingredients most commonly found in beauty and personal care products—particularly those linked to irritation, hormone disruption, environmental toxicity, and cancer risk. It’s a practical yet powerful tool for protecting your skin and overall wellness—and a reflection of Periidot’s uncompromising commitment to your health, your skin, and the planet.

Ingredients are sourced through regenerative and sustainable practices—prioritizing minimal waste, carbon mindfulness, and packaging made of glass, aluminum, biodegradable materials, or recycled ocean-bound plastic. All brand partners manufacture their products in the US in owned and operated facilities, ensuring greater transparency, traceability, and integrity at every step.

Every treatment at Periidot is a transparent exchange—designed to educate as much as it nurtures. You’ll always know what’s being applied to your skin, why it was chosen, and how it supports your long-term skin health. No secrets, no guesswork—just clear, intentional care that empowers you to make informed decisions on your skincare journey.
