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.

ACTIVE INGREDIENTS

BIO-THERATIC® COMPLEX

Dr. Rossi’s proprietary ingredient composite harnesses the power of biomimetic sea anemone peptide, niacinamide, and hyaluronic acid in a unique, optimized ratio to help fight the visible signs of premature aging caused by sensitization in skin.

CENTELLA ASIATICA

A botanical extract rich in triterpene saponins that soothes inflammation, supports barrier repair, and calms reactive skin. Dr Rossi formulated this ingredient to attack the same inflammatory breakdown of collagen. Combined with his peptide formulation this ingredient helps to protect the skin from oxidation and stop collagen breakdown. It has been used in dermatology for its ability to accelerate healing and reduce redness, making it well-suited to sensitive, rosacea, and post-procedure skin.

SACCHARIDE BLEND

This specially curated blend of saccharides, or sugars, works in tandem with hyaluronic acid to help lock moisture into the skin, boosting and maintaining hydration.

TAMARINDUS INDICA SEED GUM

Extracted from tamarind seeds, this potent plant derivative has been shown to help promote smoother skin and, with its well documented antioxidant properties, help prevent visible signs of premature aging.
