Jumiso - Niacinamide 10 Serum

Ce sérum combine niacinamide 10%, acide tranexamique et acide succinique pour agir sur trois fronts : resserrement des pores, régulation du sébum et effacement des taches et marques post-acné. Le squalane et l'acide hyaluronique assurent une hydratation légère sans film gras. Les premières améliorations sur la texture de peau sont généralement visibles en 3 à 4 semaines d'utilisation régulière.

Apply a few drops morning and night after toner, before moisturizer. The watery texture absorbs quickly — no need to wait before moving on to the next steps. In the evening, you can layer it under a restorative active ingredient. In the morning, always pair it with an SPF: without sun protection, tranexamic acid and niacinamide won't be able to prevent spot recurrence.

Yes. Niacinamide is one of the best-tolerated active ingredients, even for sensitive skin. This serum can be used morning and evening without interruption. If you have very reactive skin, start with an evening application only for two weeks before transitioning to twice a day.

Niacinamide combines well with the majority of active ingredients: hyaluronic acid, retinol, peptides, ceramides. The precaution to remember: avoid layering it with pure vitamin C (ascorbic acid) in the same step, as one can reduce the effectiveness of the other. Alternate morning/evening or use stabilized formulas. With AHAs/BHAs, apply exfoliants first and let them set for a few minutes.

The Niacinamide 10 Serum is suitable for all skin types, including sensitive skin: it works gradually on pores and complexion with virtually no risk of irritation. The Niacinamide 20 offers double the concentration, suitable for skin accustomed to active ingredients that want faster results on sebum and imperfections. If you are unsure about your tolerance, start with the 10% version.
