That’s a good question on Equol. I first became familiar with this when prepping for my Anti-Aging and Regenerative Medicine Boards a few years ago.
I’ll let Vera-Health.ai do the talking for me on this:
Equol, a phytoestrogen derived from soy isoflavones, has shown potential benefits in topical skincare due to its antioxidant and anti-aging properties. As a metabolite of daidzein, equol can mimic estrogen by binding to estrogen receptors, which is particularly beneficial for estrogen-deficient skin conditions, such as those experienced post-menopause1.
The antioxidative properties of equol are significant in skincare as they help neutralize free radicals, reducing oxidative stress and preventing damage to skin cells. This action is crucial in maintaining skin structure and function, thereby combating signs of aging 3. Additionally, equol has been shown to enhance skin regeneration and improve structural and molecular parameters, such as maintaining telomere length and modulating epigenetic markers in skin cells, which are vital for skin longevity and appearance 3.
Equol’s phytoestrogenic characteristics not only support skin health but also contribute to its regenerative properties, making it a promising candidate for anti-aging skincare formulations. It can be integrated with other topical treatments, such as sunscreens, retinoids, and other antioxidants, to provide comprehensive skincare. This combination helps in preventing and treating signs of aging, including protection from UV damage, enhancement of skin renewal, and reduction of oxidative stress 2.
In summary, equol represents a valuable component in topical skincare products aimed at improving skin health and combating aging. Its multifunctional properties, including antioxidative, phytoestrogenic, and epigenetic effects, make it a versatile ingredient for enhancing skin regeneration and maintaining a youthful appearance. However, while promising, more extensive clinical studies are needed to fully understand its efficacy and optimal use in topical applications.

The overarching theme for this review is perspective. Superfoods (a marketing term for fruits and vegetables, etc.) have a positive connotation, while many superfoods contain phytoestrogens, a term that is alarming to the public and has a negative connotation because phytoestrogens are endocrine-disruptors, even though they are strong antioxidants that have many health benefits. To understand phytoestrogens, this paper provides a brief summary of the characteristics of: (a) estrogens, (b) estrogen receptors (ER), (c) estrogen-deficient skin, (d) how perspective(s) get off track, (e) phytoestrogen food sources, and (f) misconceptions of phytoestrogens and food safety, in general, that influence person(s) away from what is true. Finally, a brief history of cosmetics to nutraceuticals is covered plus the characteristics of phytoestrogens, resveratrol and equol on: (g) estrogen receptor binding, (h) topical and oral dosing, and (i) in vitro, molecular mechanisms and select clinical evidence, where both phytoestrogens (resveratrol and equol) demonstrate promising applications to improve skin health is presented along with future directions of nutraceuticals. Perspective is paramount in understanding the controversies associated with superfoods, phytoestrogens, and endocrine-disruptors because they have both positive and negative connotations. Everyone is exposed to and consumes these molecules everyday regardless of age, gender, or geographic location around the world, and how we understand this is a matter of perspective.
