Fermented Ingredients: Not Just For Your Kitchen

Does fermented skincare work? Absolutely. Incorporating fermented ingredients into products to help 30, 40, 50, or 60-year-old skin might sound like an unusual concept at first, but the science behind this skincare breakthrough is pretty simple (and a whole lot of ingenious!). 

The fermentation process breaks down the ingredients into smaller components that the skin can absorb more easily. For mature skin, that’s especially beneficial. As skin ages, it often becomes drier and less efficient at holding moisture. Ingredients that support hydration and help the skin maintain balance tend to attract attention for that reason. That’s right where two particular types of fermented ingredients enter the conversation.

Galactomyces are a type of yeast ferment originally discovered during the sake brewing process. 

Rice ferment is a low-pH liquid produced by soaking or boiling rice and then allowing it to ferment for several days.

Both have a long history in Korean skincare, and both are recognized for their ability to brighten and hydrate the complexion.

FAQs About Galactomyces Ferment and Fermented Rice

Can galactomyces and fermented rice be used together in the same routine?

Yes, many people combine them without any issue. Because both ingredients are generally lightweight and hydrating, they tend to layer well with other skincare products. Some routines use a fermented rice toner or essence first, followed by a galactomyces serum to add an extra layer of hydration. When introducing multiple fermented products, it is usually best to add them gradually, so the skin has time to adjust.

Which skin types benefit most from fermented skincare?

Fermented ingredients are often recommended for dry or dull skin because of their hydrating properties. Mature skin can also benefit, particularly when the complexion feels less resilient than it once did. That said, many fermented formulas are lightweight enough for combination or oily skin as well. The key factor is the product’s overall formulation rather than the ferment itself.

How often should fermented skincare products be used?

Most fermented toners, essences, and serums are designed for daily use. They are typically gentle enough to apply both in the morning and at night as part of a regular routine. As with any new skincare ingredient, starting slowly can help avoid irritation. Using the product once a day at first allows the skin to adjust before increasing the frequency if needed.
