Topical Replenishing Serum

The estriol and estradiol used to make up this formula originate from diosgenin, a phytosteroid extracted from soy. Bi-Est+ is delivered using proprietary lipid nanoparticle technology for enhanced absorption compared to conventional creams.*

Patent-pending Quicksilver Delivery Systems® improve upon liposomal and emulsification technology with smaller, more stable particles made from the highest grade ingredients available.* This nanoformulated BI-EST Topical Replenishing Serum delivers fast and enhanced absorption of Estriol and Estradiol bypassing liver metabolism for optimal effects.*
