Healthy skin depends on a resilient, well-coordinated barrier system. When this system is compromised, the skin may become dry, reactive, inflamed, and unpredictable—often all at once. At IOKA Skin+Science, our formulations are designed to support the skin’s four interconnected barriers: physical, chemical, microbial, and immunological.

Rather than forcing visible results through aggressive actives, IOKA focuses on restoring barrier function and cellular balance. This approach begins by removing chronic disruptors and replacing them with biologically compatible ingredients that work in harmony with the skin’s natural physiology.

A foundational principle of IOKA formulation is the complete avoidance of chemical emulsifiers. While commonly used to stabilize conventional skincare products, emulsifiers can interfere with the organization of barrier lipids over time. Instead, IOKA relies on natural phospholipids derived from soy or sunflower—the same class of lipids that form human cell membranes. These biomimetic phospholipids support barrier structure, improve hydration retention, and enhance cellular communication rather than disrupting them.

All IOKA formulations are further enhanced with liposomal delivery systems, designed to improve the penetration and bioavailability of key actives. Liposomes—microscopic phospholipid vesicles—encapsulate active ingredients and facilitate controlled, targeted delivery into the skin. This allows for deeper, more efficient interaction without compromising barrier integrity or triggering irritation.
