Hydrobiome Serum is an EWG Verified (pending) formulation designed to improve overall skin health through balancing the microbiome and strengthening the skin barrier. This advanced formula combines two clinically proven actives — TCP, a patented, TLR2 modulator developed by Signum Biosciences that calms irritation and targets C. acnes and TPNa, a next-generation, form of water-soluble Vitamin E chosen for its antioxidant protection and ability to strengthen the skin barrier. Lightweight and fast-absorbing, Hydrobiome Serum delivers a refined, soothing experience that nurtures long-term skin health and balance in your microbiome.
