What Is Saccharomyces/Imperata Cylindrica Root Ferment Extract?

Saccharomyces/Imperata Cylindrica Root Ferment Extract is a blend of fermented ingredients combining baker's yeast (Saccharomyces) with an extract from imperata cylindica root, a tropical grass. The fermentation process breaks down plant compounds into smaller molecules, which may enhance their skin-conditioning properties.

In skincare formulations, this ingredient functions primarily as an emollient, helping to soften and smooth the skin surface by reducing water loss.

How It Works

Fermented extracts work by delivering smaller, more bioavailable plant compounds that can penetrate the skin more easily than whole plant material. The yeast fermentation also produces beneficial byproducts including amino acids and polysaccharides, which support hydration at the skin surface.

As an emollient, the extract creates a light protective layer that reduces transepidermal water loss (TEWL), helping skin feel hydrated and soft without a heavy or occlusive feel.

Clinical Evidence & References

Research specifically on this ferment blend is limited, though fermented ingredients in general have been studied for their hydrating and skin-conditioning properties. Yeast-derived ferments are known to contain amino acids and B vitamins that support skin health.

Evidence for this particular combination remains largely empirical and based on cosmetic use rather than published clinical trials. Further research would help establish specific efficacy claims.

How to Use

This ingredient is typically incorporated into serums, moisturisers, and hydrating treatments where it works well alongside humectants like glycerin or hyaluronic acid. It can be used daily as part of your regular skincare routine and tends to work harmoniously with most other ingredients.

Safety & Precautions

Generally well-tolerated and suitable for most skin types. Those with yeast sensitivities should patch test first, though topical use is typically safe even for sensitive skin.
