Pfect-A Pro Barrier Sitosterol 0.5% Cream is a concentrated barrier-repair treatment formulated to calm inflammation, reduce visible redness, and restore compromised skin defenses. Powered by 0.5% β-Sitosterol—a plant-derived phytosterol that mimics cholesterol found naturally in the skin—this cream helps rebalance lipids, strengthen the barrier, and soothe reactive or stressed complexions. Pro-Vitamin B5 and squalene deliver deep hydration while supporting tissue repair, improving resilience, and accelerating recovery.
