Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A fermentation-derived ingredient created by culturing Saccharomyces yeast on honey. The resulting filtrate contains amino acids, sugars, and other beneficial compounds that can support skin hydration and comfort.

How it works

When applied to the skin, the small molecules from the fermentation process can help attract and retain moisture (humectant effect). It may also support the skin's natural barrier function by providing nutrients that help keep skin cells healthy and hydrated.

Pros

Gentle hydration

Provides moisture without clogging pores or feeling heavy, making it suitable for most skin types.

Soothing potential

May help calm redness or irritation due to the fermentation process, which can produce skin-friendly compounds.

Cons and cautions

Limited evidence

Most benefits are based on anecdotal reports and small studies; more research is needed to confirm long-term effects.

Allergy risk

Rare but possible for those with yeast allergies; patch testing is recommended before widespread use.

Best for

  • People with dry or dehydrated skin
  • Those looking for a gentle, fermented ingredient

Use caution if

  • Individuals with known yeast allergies or sensitivities

Usage tips

Apply after cleansing and before heavier creams to maximize absorption.
Store products containing this ingredient in a cool, dark place to preserve stability.

Safety summary

Considered safe for topical use in cosmetics. Patch testing is recommended for those with sensitive skin or yeast allergies.
