B3 Defence Barrier Repair Waterless Serum Pillows are a targeted barrier-support treatment designed to help restore stressed, dehydrated, and compromised skin. Each waterless pillow keeps active ingredients protected in a dry, concentrated format until activated with SKIN PJ’s Activator Face Mist. Once misted, the pillow dissolves into a fresh serum on the skin, delivering a precise dose of high-performance actives with every use. Powered by 17% Niacinamide, B3 Defence helps strengthen the skin barrier, support moisture retention, improve the look of uneven tone and calm visible redness. Hyaluronic Acid delivers instant hydration and a plumping effect, helping skin feel softer, smoother, and more comfortable. Vitamin B12 supports skin renewal and helps soothe the look of stressed or irritated skin. This treatment is ideal for skin that feels dry, tight, reactive, unbalanced or in need of barrier support.
