KrX Milk Boosting Serum is a nourishing Korean barrier serum formulated to restore hydration, strengthen compromised skin, and brighten uneven tone without overwhelming sensitized complexions. The formula features 208,000 ppm of Lactobacillus/Milk Ferment Filtrate to support a balanced skin environment and promote a calmer, healthier-looking barrier. A five-ceramide complex—including ceramide NP, AP, AS, NG, and glycosphingolipids—works with hydrogenated lecithin and phytosterols to replenish essential lipids and reduce moisture loss. Squalane and shea butter provide additional softness and lasting nourishment. Niacinamide and Saccharomyces/rice ferment filtrate help improve dullness and uneven tone, while vitamin E provides antioxidant support. Milk protein extract and hydrolyzed pea protein condition the skin and visibly smooth uneven texture. Best for compromised skin barriers, dehydration, sensitivity, dullness, uneven tone, and rough texture. 105ml
