Our Oath

100% Clean + Sustainably Sourced

There are no parabens. silicons, artificial fragrances, petroleum, sulphates, phthalates, PEGs, DEA, TEA, or any other chemicals in our skincare. Made with ingredients that are organic, wildcrafted, or natural, cruelty-free and sustainable.

Small Batch

Our dermis products are lovingly crafted in small batches by hand with proprietary formulas that have been carefully created and tested for optimal efficacy.

Plastic-free and reusable

Part of our mission is to continually push the envelope of skincare industry packaging. All of our bottles, stoppers, droppers and facial tools are entirely plastic-free. We keep them unbranded and beautiful so that you'll love using them over and over.

A Grounded application

The slow pour

The old-school pour. It's such a simple thing, yet it's hard find a skincare option out there that doesn't have a complicated plastic pump or bulb dropper or a spray. Are all the little parts really necessary?

It takes a little practice to get the tilt, but more so it just takes presence.

Sometimes rather than innovate we just need to strip away the over-complications.

An enduring alternative.

If you typically use a dropper, our hand-carved crystalline facial massage wand functions as one, making it effortless to lift and dispense a precise number of droplets into your hand. It also doubles as a facial massage tool.

Ethically sourced and artisanally carved, this design serves multiple purposes and can endure use upon use over time. Our crystalline wands have never seen the inside of a factory and are carefully cut to minimize wastage.

The unbranded bottle

We don’t brand our bottles. We love our logo, but you probably don’t care to see our name every time you lift the bottle. There is enough constant, subliminal exposure to branding, marketing, and messaging throughout any given day.

The Timeless Bottle

We encourage reuse and that’s the second reason why we keep our bottle unbranded. You’ll like it better unstamped. We dream that one day your bottle will be considered “vintage” or “antique” and be truly functional in a number of uses around the home.

The Borosilicate Bottle

We chose all glass to eliminate plastic completely, but we choose borosilicate for the following reasons: 1) completely safe and nontoxic, and does not leach 2) Unlike standard type III glass, it’s resistant to thermal shock. So when you decide reuse the bottle, feel free to boil it. 3) Because of the thickness we are able to achieve with this type of glass, it’s 30% lighter than the ubiquitous boston round in a comparable size.

The Wax Sealed Bottle

We ship our bottles sealed with natural wax. We've been tweaking our method for years. Our solution is unconventional. It’s not machinated, and therefore it comes with imperfections. No bottle is a perfectly cloned iteration of the last one. To us that's all the messaging needed.

Shroom serum is made with:

Snow Fungus

Tremella Mushroom is a moistening Yin tonic in TCM, recorded since the Tang Dynasty as a secret ally of skin and tissue health, with anti-inflammatory properties.


The mineral and antioxidants in marine algae work to support the skin barrrier, allowing damaged skin to heal.

Reishi Mushroom

Reishi's adaptogenic properties support the flow of cell renewal, gradually restoring the the skin's natural ability to regulate itself.

Lactobacillus ferment

Probiotics nurture an ecology of beneficial microbes amidst the skin's microbiome.

Rosa Damascena Flower

A hint of the highest quality rose extract infuses this snowy, translucent elixir with notes of mist and moss.
