About SR17

SR17 Face Cream is a small-batch face cream built around one of the most clinically validated skin regeneration ingredients on the planet - tepezcohuite, known scientifically as Mimosa Tenuiflora. SR17 is Saint Raphael’s proprietary extraction of that ingredient, put into a daily face cream.

SR17 works at a cellular level, stimulating the fibroblasts responsible for collagen, elastin, and hyaluronic acid production - the three biological building blocks of firm, youthful, resilient skin.

Where most skincare works on the surface, SR17 works beneath it. The result is not temporary hydration or the illusion of smoother skin - it is genuine, measurable skin renewal driven by over 40 years of skin science.

Formulated and produced in the UK in deliberately small batches, SR17 is for people who are done with overclaiming and ready for skincare that can show it’s working.

How Does it Work?

Mimosa Tenuiflora bark contains a precise combination of bioactive compounds - mimonosides, arabinogalactans, and polyphenols -  that work together to trigger the skin's own renewal mechanisms.

Fibroblast are the cells responsible for producing collagen, elastin, and hyaluronic acid - the three building blocks of firm, healthy, youthful skin. As we age, fibroblast density declines by 35% and collagen production drops by as much as 68%. Mimosa tenuiflora's arabinogalactans have been clinically shown to significantly stimulate fibroblast viability and proliferation -  targeting the root cause of skin ageing, not just the surface symptoms.

Cellular Regeneration The mimonosides found in Mimosa tenuiflora bark stimulate the mitotic index -  the rate at which cells divide and renew. This is skin renewal at its most fundamental level, triggering new cell production from within the dermis rather than simply accelerating surface shedding.

Deep Repair Unlike retinol, which works primarily by speeding up surface cell turnover, tepezcohuite works deeper -  activating the fibroblasts that build new skin from within. The result is not just smoother skin, but structurally stronger, more resilient skin over time.

Small-Batch & British-Made

Every batch of SR17 is proudly formulated and produced in the United Kingdom. As a small British business, we control every stage of production as a commitment to quality and transparency.

Small-batch manufacturing means we never have to sacrifice the concentration of our ingredients or the integrity of our formulation for the sake of scale. We make less so we can make it better.

Just one extraordinary ingredient, British-made with precision, and backed by four decades of science.
