Romilly Wilde's Peptide Longevity Serum combines advanced peptide technologies, lasting hydration, and antioxidant care to help skin look firmer, smoother, and more radiant. It is designed for skin longevity, helping skin maintain its resilient, healthy look in the face of time and everyday environmental stress.

Rather than relying on a single hero peptide, the formula brings together several peptide technologies, each chosen for a defined role. It contains Mini-Proteins®, peptide-inspired molecules that mimic the signalling involved in maintaining the skin's protein network. It also contains protein-folding peptides, which support the structure of proteins rather than simply the quantity, and matrix peptides, for the appearance of firmness and density. Refined Centella fractions support renewal over time.

In independent laboratory testing on human skin samples exposed to UV-A and pollution, samples treated with this formula showed lower levels of oxidatively damaged protein and higher Collagen I levels than untreated samples. These are measurements on excised human skin under laboratory conditions, not a study of people using the product.

British skincare built on proteomic science. Romilly Wilde formulates for the proteome, the complete network of proteins that gives skin its structure, resilience and health. Rather than building a formula around a single hero ingredient, each product draws on advanced peptide technologies, chosen for a defined role and measured in the laboratory on human skin samples. The result is skincare designed the way skin is designed: as a network. It's time to look beneath the surface.
