Why Emerald is different
Reactive skin usually gets a separate product for every job, and every extra bottle is another chance to flare. Emerald does four of them in one waterless step.
Fewer products, fewer chances to react.
Inside the bottle
A short list, with nothing added just to fill the bottle.
The algae
A freshwater algae grown in sealed tanks, then oil-extracted so its omega fatty acids and carotenoids make it into the formula.
The calm
A rare botanical oil rich in chamazulene, the compound behind its calming reputation. It soothes the look of redness.
The base · 70%
A light oil very close to one your skin makes on its own, so it sinks in without a greasy film.
The base · 30%
The closest plant match to your skin’s natural oil. Together with squalane, it carries everything else in.
No water · No synthetic preservatives · No synthetic fragrance · No silicones · No parabens · Vegan · Cruelty-free
How to use
Emerald is made for the hours your skin does its overnight work. Here’s how to give it the whole night.
Your night
A mild cleanser, then pat your face almost dry.
Why: Stripping cleansers undo the calm, and a little dampness helps the oil spread.
Rub them between your palms.
Why: Warm oil spreads in one thin layer, so a few drops go a long way.
Over your face and neck, as the final step of the night.
Why: Nothing goes on top to disturb it, so it has the whole night.
Let it sink in before your face meets the pillow.
Why: More stays on your skin and less on your pillowcase.
Two or three evenings a week
They’re the two lowest-priced products we make, and each one sets up your skin so Emerald spreads in one thin, even layer.
The polish
Micronized chlorella, milled tiny and round, polishes away dull, dry surface skin without the sharp edges of shells, salt or sugar. Colloidal oatmeal and panthenol keep it comfortable.
The reset
Bentonite and kaolin draw out oil and buildup while chlorella and colloidal oatmeal keep skin calm. A dry powder you mix fresh with the rose water mist in the box, so there’s no water in the jar.

Emerald was made for that skin: no water, no synthetic preservatives, no synthetic fragrance, and a base close to your skin’s own oils. Blue tansy is a botanical, so if you’re very reactive, patch-test on your jaw for a few nights first.
Squalane and jojoba are close to your skin’s own oils, so they sink in rather than sitting on top, and both are considered non-comedogenic. Oil isn’t the enemy. Stripping is.
Your skin does most of its repair overnight, and Emerald is made for those hours. Make it the last step before bed. For daytime, that’s what Ruby is for.
Yes. It goes on last, over any serum or treatment. If you use prescription skincare, check with your dermatologist first.
Skin feels calmer and more comfortable from the first night. A calmer, more even look builds over weeks of nightly use.
Yes. The oil is vegan and cruelty-free. (The Emerald salve uses beeswax, so it isn’t.)
Emerald by night
Three to five drops, pressed in before bed. Then sleep.

Farm-to-Face
For a long time, we couldn't find what we were looking for. There were harsh prescription treatments on one side, and feel-good natural products with little science behind them on the other. Nothing in between — especially not for sensitive skin.
So we did the research ourselves.
My wife has always been passionate about skincare — the rituals, the ingredients, what actually works and why. I came at it from a different angle. I'd struggled with acne most of my life, and I'd also become fascinated with microalgae — not just as an ingredient, but as one of the most important organisms on the planet. The more scientists study it, the clearer it becomes: algae is going to play a significant role in how humans live and eat sustainably. That felt worth paying attention to.
When we started combining those two interests — her deep knowledge of what skin actually needs, and my obsession with what algae is capable of — something clicked. We spent months researching, formulating, and testing on ourselves. What we discovered is that the skin doesn't need more actives thrown at it. It needs ingredients that work with it, delivered in a way the skin already understands.
These products came out of that process. They're what we actually use. Every morning, the two of us still do our skincare rituals together — and that hasn't changed since the beginning.
