Advanced Osmolyte System (AOS)

Advanced Osmolyte System (AOS) is a synergistic blend of naturally derived osmolytes designed to optimize cellular hydration, especially under environmental stress. By balancing osmotic pressure inside and outside skin cells, this system helps prevent water loss, boosts moisture retention, and protects cell structure. AOS reinforces the skin’s barrier function and improves elasticity, delivering fast, long-lasting hydration for smooth, supple, and resilient skin—even in challenging conditions like cold, dry, or polluted environments.

Barrier Biotic Booster (BBB)

Barrier Biotic Booster (BBB) is a microbiome-friendly prebiotic that nourishes beneficial skin bacteria to support a healthy, balanced skin barrier. By selectively feeding commensal microbes, it helps restore microbial diversity, reduce irritation, and strengthen the skin’s natural defenses against environmental aggressors. BBB enhances skin resilience, soothes sensitivity, and improves hydration—making it ideal for formulations targeting compromised, reactive, or dry skin.

Use morning and/or evening.
