Perfect for breakout-prone skin types, the Medik8 Niacinamide Peptides Serum helps to refine and balance the appearance of skin with a host of actives. Powered by 10% niacinamide, the formula helps to enhance luminosity while improving the visibility of enlarged pores, blemishes and redness. Crystalide peptide elevates the formula to promote a glass-like, radiant effect, while zinc PCA helps to minimise further breakouts with oil reduction. Complete with hyaluronic acid, the advanced blend supports and nourishes the skin's natural barrier for a comfortable, soothed finish.
