Three pairings built around Theorem Serum Boost, so the step that does the most work never has to do it alone.
Theorem has always been the center of the Caire routine. But a serum can only do so much on its own. What comes before it and what goes over it decide how much of that work actually holds.
So we built three duos. Same serum, three partners, depending on what your skin needs most right now.
Start clean
Theorem Serum Boost + The Grownup Cleanser
A barrier-first cleansing balm that melts away makeup and SPF without stripping, so your serum lands on skin that is ready for it. For anyone whose cleanser has been quietly undoing the rest of their routine.
Reset
Theorem Serum Boost + Triple Lift Molecule Mask
Hyaluronic nutrition plus the Triple Lift complex, for skin that looks firmer, smoother, and more lifted. Your reset for the days skin looks tired and flat.
Seal it in
Theorem Serum Boost + The Grownup Moisturizer
CeraLipids and Super E seal in hydration and support your barrier as the season turns. For skin that feels tight, or drinks up everything you put on it.
Grownup skincare compounds. Consistency is what builds hydration and firmness over time, and pairing is how each step protects the one before it. Clean, then treat. Treat, then seal. Every duo is a complete small routine instead of one product carrying the whole load alone.
Three pairings, one serum, one decision. Pick the partner your skin needs most right now.
