What Is Saccharomyces Lysate Extract Filtrate?

Saccharomyces Lysate Extract Filtrate is derived from baker's yeast (Saccharomyces cerevisiae) that has been broken down and filtered to create a concentrated extract. The lysate—the fluid released when yeast cells are broken open—contains proteins, amino acids, vitamins, and other compounds naturally present in yeast cells.

In skincare formulations, this ingredient functions primarily as a skin conditioner, helping to support the skin's barrier function and overall appearance. It is often included in moisturisers, serums, and treatment products where hydration and skin conditioning are desired outcomes.

How It Works

The extract contains bioactive compounds including amino acids, polysaccharides, and B vitamins that are absorbed into the skin. These components work to reinforce the skin's natural moisture barrier and provide conditioning effects that improve hydration and elasticity.

The lysate format means the yeast cells have already been broken down, potentially making their beneficial compounds more readily available for skin absorption compared to intact cells.

Clinical Evidence & References

Research on Saccharomyces Lysate Extract Filtrate specifically in skincare is limited. The ingredient is primarily supported by traditional use in fermented skincare formulations and general knowledge of yeast-derived compounds' conditioning properties.

Broader research on fermented ingredients and yeast extracts suggests they can support skin hydration and barrier function, though evidence for this specific extract would strengthen confidence in its efficacy. Most safety data comes from its long history of use in cosmetics and food applications.

How to Use

This ingredient is typically used as part of a complete skincare routine rather than as a standalone treatment. Include it in your morning or evening routine depending on the product format (serum, moisturiser, mask). There is no established limit on frequency, though follow the specific product's instructions. It combines well with other hydrating and conditioning ingredients.

Safety & Precautions

Generally well-tolerated across skin types. Those with documented yeast sensitivities should exercise caution, though topical application carries lower risk than oral consumption.
