Pick a skin care concern - Niacinamide will take it on. Simple 10% Niacinamide (Vitamin B3) Booster Serum is so versatile and treats every skin type with kindness (from dry to oily and even sensitive skin). This multitasker is powered by high-performance, 88% naturally derived ingredients to supercharge your skin care routine for instant, visible results. 10% Niacinamide (vitamin B3) and 1% B5 hydrate, soften fine lines and boost skin resilience, helping strengthen and protect your skin barrier. This Niacinamide serum regulates sebum production (avoiding greasiness and breakouts) and even helps to unclog and visibly minimise enlarged pores, improving your skin's texture and tone.

Like all Simple products, our Niacinamide serum is dermatologically tested and non-comedogenic, contains no harsh chemicals and is free from alcohol, mineral oils, artificial colours and perfume. This powerful skin care product is also PETA-Approved Vegan - we don't test on animals anywhere in the world.

Shake, drop, dab - it's that simple. After using a cleanser, apply our non-sticky, non-greasy face serum alone, or mix a few drops into your favourite moisturiser for a super-quick skin care boost. Oh, and it's fab under makeup too. Try cocktailing it with Simple 3% Hyaluronic Acid + B5** Booster Serum (add a few drops of each). It's best not to combine Niacinamide with Vitamin C, as these two antioxidants play better when used separately. If you'd like to use both in your skin care routine, we'd recommend applying our Vitamin C + E + F** Booster Serum in the morning and then using our strengthening 10% Niacinamide (Vitamin B3) Booster Serum as part of your night-time routine. We'd love to know what you think of our face serums, so leave us a review.
