Noevir Group Unveils Discovery on Soy Isoflavones

In a groundbreaking revelation, Noevir Group has identified that high-purity isoflavones derived from Fukuyutaka soybeans, using their unique extraction technology, significantly enhance skin barrier functions. This enhancement occurs by increasing levels of Cystatin A (CSTA), a protein crucial for skin barrier integrity. Not only does this discovery point to improvements at a cellular level, but it also indicates potential benefits for human skin, aiding in moisture retention and skin health.

The findings will be presented at the 26th Annual Meeting of the Japanese Society of Anti-Aging Medicine, scheduled from June 26 to 28, 2026.

Research Background

The skin’s barrier function plays a vital role in maintaining moisture and safeguarding against external irritants. A decline in this function can lead to various skin issues, including dryness and inflammation, which are exacerbated by environmental factors like UV rays and pollution. As concerns grow regarding skin immunity and barrier stability, understanding the roles of numerous proteins in the stratum corneum—where skin's barrier is primarily located—has become increasingly important.

Traditionally, the complexity of proteins involved in skin health has made it challenging to determine which significantly contribute to skin improvement. However, recent advancements in proteomic analysis technology have allowed for comprehensive studies of many proteins, paving the way for novel approaches to tackle these challenges.

Noevir Group has capitalized on this technology to delve into the skincare potential of soy milk, building from studies initiated in 2002. The latest research on high-purity isoflavones derived from soy milk aims to explore and enhance proteins that contribute positively to skin barrier functions, thereby leading to improved skin health.

Key Findings

1. Cystatin A's Role in Skin Barrier Function

Cystatin A was identified as a key player in the skin barrier's functionality. The proteomic analysis focused on the stratum corneum and correlated Cystatin A levels with Trans-Epidermal Water Loss (TEWL), an objective indicator of barrier integrity, in 43 adult participants. The study demonstrated that higher Cystatin A levels resulted in significantly lower TEWL rates, confirming its critical role in skin barrier enhancement.

2. Effects of Fukuyutaka Soy on Cystatin A Levels

Through extensive research on soybean isoflavones, Noevir Group launched a high-purity isoflavone product in 2022. Using human epidermal keratinocytes, the researchers targeted Cystatin A and tested the isoflavones' ability to elevate its levels. The results corroborated the finding that the high-purity isoflavones derived from Fukuyutaka soy increase Cystatin A levels, supporting skin barrier function and indicating a potential pathway to achieve resilient, hydrated skin.

3. Skin Barrier Support from Isoflavone Formulations

To validate the skin efficacy of the developed product containing high-purity isoflavones, a one-month trial on human subjects was conducted. The findings revealed that the use of the formulation resulted in a significant decrease in TEWL, affirming its capability to improve skin barrier functions and hydration levels.

Future Perspectives

This research has unveiled that high-purity isoflavones from Fukuyutaka soybeans can elevate Cystatin A levels, enhancing the skin's barrier capabilities. The implications of this discovery suggest that these isoflavones can unlock the skin’s inherent powers, enabling it to withstand external stressors and achieve an empowered moisturized state. As ongoing studies will focus on various other soybeans across Japan, this pioneering research opens doors to new skincare ingredients targeting skin barrier health.

Through this research journey, Noevir Group remains committed to its philosophy of enhancing quality of life through innovative cosmetic solutions, ultimately striving to create captivating moments for body and mind.
