Ingredient spotlight: saccharomyces sea silt ferment

Fermentation isn’t just for bread or wine. In skincare, it’s a way of unlocking nature’s raw materials so your skin can absorb them more easily. One of the most remarkable examples is Saccharomyces/Sea Silt Ferment — a mineral-rich extract born from the marriage of marine silt and fermentation science.

WHAT IT IS

Saccharomyces is a beneficial yeast that, when used in skincare, acts like a microscopic alchemist. When it ferments sea silt — sediment collected from clean, mineral-dense sea beds — it breaks large, complex compounds down into smaller, bioavailable forms. The result: a nutrient infusion your skin can actually recognize and use.

WHERE IT COMES FROM

Sea silt is naturally rich in essential minerals, amino acids, and organic matter layered over centuries beneath the ocean. Think of it as the ocean’s pantry, stocked with trace elements like magnesium, calcium, and potassium. Fermentation by Saccharomyces transforms this silt into a silky extract that delivers those elements directly to the skin.

WHY YOUR SKIN LOVES IT

• Bioavailable minerals: Fermentation makes trace elements more accessible, replenishing skin at a cellular level.

• Antioxidant support: Saccharomyces enhances the silt’s natural defenses, helping skin resist daily stressors.

• Barrier balance: A well-fed barrier holds hydration better and feels calmer, stronger, more resilient.

• Radiance boost: With consistent use, skin looks smoother, more even-toned, and lit with a natural glow.

THE BARRIER LOGIC

Your skin barrier doesn’t just need water and oils — it also relies on micronutrients to function at its best. Saccharomyces sea silt ferment provides those in a gentle, bioavailable stream, replenishing what modern life often strips away.
