Ruby · Cell-Defense
All of the antioxidant defense. None of the sting.
Ruby is built on astaxanthin, the deep-red antioxidant a freshwater algae makes to survive harsh sun, in a waterless oil made for sensitive skin.
-
Covers the whole cell. Works in both the oily and the watery parts of a skin cell. Most antioxidants only cover one.
-
Nothing to sting. No acid, no water, no synthetic fragrance. Made for skin that vitamin C has stung before.
-
0 ocean contaminants. Grown in sealed freshwater tanks, it never touches the ocean. The red is the ingredient itself, not a dye.

- Free US shipping over $65
- Made in small batches
Why Ruby is different
Most antioxidants guard half a cell. Astaxanthin guards both.
Every skin cell is an oily outer layer around a watery inside. Vitamin C only works in the water. Astaxanthin’s molecule is long enough to reach across both, so one ingredient covers the whole cell.
And it works at a neutral pH, so there’s no acid to sting.

Straight answers
Will it sting like vitamin C did?
It shouldn’t. Astaxanthin doesn’t need an acid to work, and there’s no alcohol, water or synthetic fragrance in the bottle. If your skin is very reactive, patch-test on your jaw first.
Will an oil clog my pores?
The base is 70% squalane and 30% jojoba, a blend close to your skin’s own oils, so it sinks in instead of sitting on top. Both are considered non-comedogenic.
Is Ruby a sunscreen?
No. It has no SPF and doesn’t replace sunscreen. Press it in each morning, then put your sunscreen on over it. They do different jobs.
Will it stain?
It can, before it absorbs. The red is real astaxanthin, not a dye, so give it a few minutes before white pillowcases or towels.
When will I notice a difference?
Skin feels softer and more comfortable from the first use. A brighter, more even look builds over weeks of daily use. It’s a daily habit, not an overnight fix.
Why does it cost more than a drugstore oil?
Clean astaxanthin is slow and expensive to grow. Ours comes from sealed freshwater tanks, and every batch is mixed by hand in small runs. Ruby took 34 formulations before the dose and the base were right.
Why it’s red
An algae that turns red to survive the sun.
When the freshwater algae Haematococcus pluvialis is stranded in harsh sunlight, it floods itself with astaxanthin and turns deep red. That red is exactly what’s in the bottle, at a strength you can see.
