Realbarrier specialises in products designed to strengthen and repair the skin's natural barrier, particularly for those with dry, sensitive, or compromised skin. Real Barrier's formulations are rooted in dermatological science and are free from harsh additives like parabens, mineral oils, and artificial fragrances. A cornerstone of Real Barrier's approach is its patented MLE (Multi-Lamellar Emulsion) technology. This innovation mimics the skin's natural lipid structure, utilizing plant-derived ceramides, fatty acids, and cholesterol to restore and reinforce the skin barrier. The MLE formula enhances moisture retention and shields the skin from environmental stressors, providing a rich yet non-greasy texture that absorbs quickly. Retiniol Pore Tightening Serum is a lightweight yet powerful treatment that targets pore concerns, pore area, index, depth, texture, and even vertical and horizontal pores, especially in the face’s central “butterfly zone,” leaving skin visibly firmer and more elastic. Stabilised with advanced dual liposome technology, it delivers 0.1% pure retinol that’s encapsulated twice - first as a retinol nanoemulsion in porous silica, then re-encapsulated for enhanced stability and deep absorption. Its signature Retiniol complex combines liposome retinol (smaller than a pore) with 99% pure, plant-derived bakuchiol for a synergistic firming and lifting effect, while niacinamide, triple ceramides, hyaluronic acid, and vitamin E refine texture, smooth fine lines, reinforce the skin barrier, and lock in lasting hydration. Hypoallergenic and safe for sensitive skin. Store in a cool, dry place away from direct sunlight South Korea
