Neocutis Biosilk Expert Kit

The kit bundles a three-step home regimen: a cleanser, a serum, and a cream, all built around the patented Biosilk ingredient. Neocutis, a Swiss-founded skincare label best known for its PSP (Processed Skin Cell Proteins) technology, positions these kits as a complete anti-aging routine rather than a single treatment.

Biosilk is a patented ingredient derived from umbilical cord lining extract. According to Neocutis's positioning, it supports collagen production and helps improve skin texture, placing it in the same growth-factor category as the brand's signature PSP complex.

The standard sequence is cleanser first, then serum, then cream as the final sealing step. Because the serum carries the concentrated Biosilk actives, applying it to freshly cleansed skin before the cream maximizes absorption.

Neocutis products are generally retinol-free and designed to be layered, with the kit focusing on hydration and collagen support rather than exfoliation. If you add a retinol at night, many users apply the kit's serum and cream on top, but check with your dermatologist since Neocutis is a professional-dispensed brand.
