We’re still tracking retailers for this one. In the meantime:
Avène's flagship hydration serum — and one of the cleanest niacinamide + hyaluronic acid formulations in the French pharmacy lineup. The formula stacks two molecular weights of hyaluronic acid with niacinamide for surface and mid-depth hydration plus tone-evening, all suspended in thermal spring water and trehalose for additional osmotic balance. 96% ingredients of natural origin per Avène's own classification. Fragrance-free, paraben-free, sulfate-free. The 'concentrated' framing is supported by the brand's 48-hour hydration claim — clinically tested — rather than active concentration. At $44 for 30ml, it sits in the same niche as La Roche-Posay's Hyalu B5 but with a cleaner, more sensitive-friendly profile.
