The Logic Hydrating Gel seals the ritual with three simultaneous actions: sodium hyaluronate and glycerin draw moisture to the surface, aloe vera and panthenol anchor it in deeper layers, and plant-derived squalane lays a protective veil that is neither occlusive nor shiny. The 3% niacinamide extends the evening effect of the essence, while centella asiatica extract and allantoin calm any residual redness and reinforce the skin barrier over time. Its water-gel texture melts instantly into the skin and dries to a comfortable satin finish — ideal beneath sunscreen or foundation. Suited to all skin types, including sensitive and acne-prone. Step 3 of the Logic routine.
