Reactive skin runs hot — flushing at temperature changes, tightening after cleansing, reacting to products that suit everyone else. This daily serum is designed to make it steadier. Niacinamide, Sodium Hyaluronate and Vitamin B5 work together on the skin's natural barrier function, which is usually the underlying issue rather than the visible symptom. Niacinamide supports barrier strength over time, Sodium Hyaluronate delivers immediate hydration, and Vitamin B5 helps skin feel soothed and comfortable. The visible payoff is softer-looking redness and smoother texture; the deeper one is skin that copes better week to week. The texture is light and slips easily under moisturiser, so it adds a step without adding weight. Thirty millilitres, suitable for sensitive skin, and gentle enough to use morning and night rather than saving for flare-ups.
