SACCHAROMYCES/CITRUS JUNOS PEEL FERMENT FILTRATE.

Valuable CAS - / SKIN CONDITIONING

This unique ferment filtrate combines the biological power of Saccharomyces with the rich antioxidant profile of Citrus Junos (Yuzu) peel. It delivers essential nutrients and a potent blend of antioxidants to the skin, aiming to enhance elasticity, hydration, and overall texture while mitigating inflammatory responses.

Science

This precision-fermented ingredient functions through a multi-pronged approach to optimize skin health. It provides a spectrum of vital nutrients and robust antioxidants, notably anthocyanins, carotenoids, and flavonoids derived from Citrus Junos peel, which actively neutralize oxidative stress and demonstrate antiglycation activity. This promotes vigorous skin cell proliferation and turnover, fostering rejuvenation and maintaining balanced hydration. The ingredient is anticipated to reduce inflammation, stimulate collagen synthesis for improved skin elasticity, and visibly diminish fine lines and wrinkles. Furthermore, ferment filtrates in general have been observed to regulate sebum production, reinforce the skin barrier by upregulating key proteins, and lessen redness. They may also reduce hyperpigmentation through targeted melanin synthesis inhibition and contribute to the repair of UVB-induced skin barrier damage by restoring crucial epidermal differentiation, tight junction integrity, and moisture retention proteins.

Stability

A patch test is recommended prior to extensive use. When formulating with citrus-derived components, it is crucial to ensure the final product is non-sensitizing and non-irritating. For leave-on products, the concentration of 5-methoxypsoralen (5-MOP) must not exceed 0.0015% (15 ppm).

The Saccharomyces Ferment Filtrate component is widely considered safe, supported by robust data, GRAS status, and its reported usage in cosmetic formulations up to 2% according to 2023 US FDA VCRP data. The Cosmetic Ingredient Review (CIR) Expert Panel deems citrus fruit-derived ingredients, including Citrus Junos peel, safe for use in both rinse-off and leave-on cosmetic products when precisely formulated to be non-sensitizing and non-irritating, adhering to the 0.0015% (15 ppm) 5-methoxypsoralen (5-MOP) limit for leave-on products.
