The Catalyst

$198.00
Rated 4.7 out of 5
Based on 67 reviews

Smoother texture. Less redness. Firmer, more elastic skin. The Catalyst is a silky daily serum clinically proven to deliver all three — in as little as 4 weeks.

Formulated with Bio-Theriac® complex, it targets TRPV1 receptors — the cellular triggers behind inflammation, sensitivity, and accelerated skin aging — to calm reactivity while actively renewing the skin's surface. The result is visibly younger-looking skin without the irritation of retinoids or vitamin C.

Appropriate for all skin types including sensitive, dry, combination, and oily.

Post-Treatment & Post-Procedure Protocol:

Maximize your aesthetic investment with this clinically proven serum that complements most professional treatments from injectables like Botox and fillers to lasers (both ablative and non, like Fraxel, Moxi, Morpheus8, IPL), peels, microneedling and more. The Catalyst's TRPV1 antagonist technology delivers measurable improvements in skin texture, elasticity, and fine line reduction, demonstrated in 4-week clinical trials with 63% improvement in skin texture. This dermatologist-developed formula provides the perfect bridge between professional treatments and at-home care, ensuring sustained results across all aesthetic modalities. As always consult with your physician or practitioner on post-procedure recovery.
