Give your skin what it needs for the season ahead: a serum that addresses inflammation at the source, and daily protection that keeps results in place. The Catalyst — Your Glow, Backed by Data The Catalyst targets TRPV1 receptors — the cellular trigger that sets off inflammation before it can show up on your skin. In clinical trials, 96.8% of participants saw improved texture, with 87% reporting smoother, more rejuvenated skin after consistent use. Formulated with our proprietary Bio-Theriac® Complex, it's gentle enough for daily use — 94% of participants found it comfortable for full-face application, even those with sensitive skin. The Day Formula — Protection That Doesn't Undo the Work Glow is only half the equation. The Day Formula delivers daily SPF protection formulated to complement your routine — helping guard the progress your serum makes, so what you build in the morning doesn't get undone by the environment. Why This Pairing - Full-size Catalyst Serum, plus a full-size Day Formula, free - Paraben, fragrance, and dye-free — always tested on sensitive skin - Dermatologist approved, certified cruelty-free Add both to your routine this summer — one to calm and repair, one to protect what you've earned.
