The Ordinary's 100% Niacinamide Powder is perfect for those who're already obsessed with the bestselling serum, but want to be able to tailor their usage to better address their skin's own, unique needs. An excellent all-rounder, niacinamide - also known as vitamin B3 - has a spectrum of benefits, from minimising visibility of pores to improving uneven skin tone, fortifying barrier function, diminishing dullness and softening fine lines and wrinkles as well as reducing the redness that follows a blemish. With so many strings to its bow, there's a reason it's making a name for itself amongst clued-up skin care connoisseurs - and now, in this 'mixable' format, you're able to marry its benefits with other (non-conflicting) formulations to address several needs in one step. Readily water soluble, this can be added to your favourite water-based creams and serums, providing that the p H is between 5.0 and 7.0 (so nothing too acidic or too alkaline) - for example, it's perfect when used to boost The Ordinary's {Hyaluronic Acid 2% + B5}, {Natural Moisturizing Factors + HA}, {"Buffet" + Copper Peptides 1%} or {Matrixyl 10% + HA}. to name a few.£28.5 per 100.00g
