OUR PHILOSOPHY

For People & Planet

Imagine a world where our quest for beauty didn’t put us at odds with our planet. We are inspired by such a world. One Theory products are formulated with people-friendly and earth-friendly ingredients to keep our global impact meaningful and big–but only where it counts. We are One Theory, For People & Planet–and we mean it.

Did You Know?

While you’re making yourself gorgeous, you can help our planet glow up too! Every single order you place with us plants 5 trees. One Theory has partnered with Eden Reforestation Projects to replant and restore precious lost forests in Kenya with every single order. One Theory is all about the power of ONE–one person, one order, and one day–building into something truly great.

BUILDING YOUR SKINCARE RITUAL

Our basic regimen builds on what you're already probably doing twice a day--cleansing your face and minding your business.
We like to call these day and night cleansings, ``rituals.`` Oh yes, we're fancy.

Cleanse

To remove dirt, oil and impurities from the skin.

Tone

To remove cleanser residue, tighten, and prep skin for serums.

Treat

To target issues and meet your skin's changing daily needs.

Moisturize

To condition and seal in the goodness layered on before.

Seize the Day

Glow & go! Go out there and do something awesome.
