Senskin+ works by reducing the skin's hyper-reactivity response rather than just soothing after the fact - over time your skin becomes genuinely less reactive, not just temporarily calmed. Biome Care+ supports the microbiome layer that sits between your skin and the outside world, when this is balanced, far fewer things trigger a reaction. This duo deliberately avoids all common sensitising ingredients: no fragrance, no harsh actives, no unnecessary anything. Pure Ainhoa philosophy.
