20% niacinamide — a high-strength serum that minimises pores and brightens skin tone.

The Isntree Hyper Niacinamide 20 Serum delivers a high-strength 20% concentration of niacinamide to visibly minimise the appearance of enlarged pores, improve overall skin texture and brighten uneven skin tone. Zinc PCA and sodium PCA support hydration alongside the high-strength active, reducing the dry, tight feeling that pure niacinamide formulas can sometimes leave behind.
