Soy extract contains a group of compounds called isoflavones, which have been shown to have anti-inflammatory and antioxidant properties. These properties can help to protect the skin from damage caused by free radicals and reduce inflammation, which can contribute to aging and skin damage. Additionally, soy extract has been shown to increase collagen production and improve skin elasticity, which can help to reduce the appearance of fine lines and wrinkles. Soy extract is also known to help with hyperpigmentation, as it can inhibit the production of melanin, which can help to even out skin tone.
