Isoflavones are phytoestrogens and natural skin boosters that act on certain signs of skin aging due to the decrease in estrogen levels
during menopause. With regular use, they can help to improve skin texture and hydration, reduce the appearance of fine lines and wrinkles, and even out skin tone.


Isoflavones are a type of phytoestrogen, which are plant-based compounds that have a similar structure to the hormone estrogen in the human body. They have been studied extensively for their ability to help safely to counteract certain signs of skin changes during menopause, which are attributed to declining levels of estrogen.

Isoflavones are considered safe for topical use and are widely available as a skincare ingredient. However, individuals who are pregnant or lactating should avoid using isoflavones, as well as individuals who have hormone-dependent cancers.
