What is Fermented Yeast (Pitera)?

A brightening ingredient rich in vitamins, minerals, and amino acids produced through yeast fermentation

Famous as the key ingredient in SK-II, it promotes skin turnover and improves skin texture and tone.

Key properties & actions

Fermented yeast filtrate (commonly known as Pitera) is known as a fermentation by-product rich in vitamins, minerals, amino acids, and organic acids produced during the fermentation of yeast. Research suggests these components may help condition the skin surface environment and support moisture retention, contributing to a noticeably smoother skin texture and more even tone.

How to manage

It is typically used in the form of a fermented toner or essence, applied immediately after cleansing by gently patting into the skin with the hands or a cotton pad. As fermented ingredients carry a characteristic scent, starting with a small amount to allow your skin to adjust is recommended. If stinging or breakouts recur during use, discontinuing use and consulting a dermatologist is recommended.

Good to know alongside

Fermented yeast filtrate is often discussed alongside other fermented ingredients such as galactomyces and bifida ferment lysate, and is frequently mentioned together with niacinamide in the context of texture and tone management.

Everyday care tips

Rather than saturating a cotton pad and wiping the essence across the skin, pressing it in with the palms may help minimize water loss.
