Australian Non-Toxic Awards, 2020 finalist, serumKakadu plum grows across the north of Australia, in heat and hard light. Over thousands of years it has filled its fruit with vitamin C. Patagonian wakame lives where cold water meets strong light.
Your skin has spent years in that light too. Spots, uneven tone and a flatter look are what skin shows after a life lived outdoors. Nothing to be ashamed of, and nothing to scrub away.
Theme Rains has formulated with these plants since 2006. C=mc2 is her answer to one question: what would it take for skin to look clear and bright again, using only what plants already know?
“Vitamin C is a highly unstable molecule in the presence of oxygen but this instability is what makes it so effective in preventing cell and tissue damage.”
C=mc2 is made in our own GMP cleanroom in the Byron Bay hinterland, on Bundjalung Country. We do not send our formulas to a contract lab. The people who blend it are the people who answer your emails.
Every batch goes through Energy Imbued®, our proprietary process. In our words: it clears the ingredients of what they pick up in transit, then harmonises the finished formula to hold more life force.
The ritual asks one thing of you too. When you press the serum in, picture your skin clear, bright and luminous. That is part of the directions.
Brightening. One oThe world’s richest natural source of vitamin C: stable, bioavailable and ready for your skin.r two sentences on what it does.
Evening. Antioxidant rich. Brightens the complexion and evens the look of skin tone.
Clarifying. Upcycled bark from Canada’s boreal forest, at the 1% level used in its clinical study. Softens the look of pigmentation and age spots.
In the study, 24 women aged 52 to 70 applied a 1% Borēaline® Aurora cream twice a day for 14 days, with a placebo on the other side of the face.
Protecting. A seaweed rich in fucoidan, for clearer, more luminous skin that looks smoother.
Hydrating. Vegan. Hydrates and plumps.
Soothing. Soothe, calm and comfort.
Vitamin C works alongside your sunscreen. It does not replace it. And it is a daily ritual, not a one-night fix: our reviewers talk about consistent use.
Patch test before first use. A 15ml bottle at one pump twice a day lasts about a month.
