Simple Booster Serum 10% Niacinamide (Vitamin B3) 30ml

Pick a skin care concern – niacinamide will take it on. This powerful all-rounder is so versatile and treats every skin type with kindness (from dry skin to oily and even sensitive skin). Our new Booster Serums contain high-performance ingredients to supercharge your skin care routine for instant, visible results. 10% Niacinamide (vitamin B3) and B5 hydrates, smooths and helps to strengthen and protect your skin barrier, and improve your skin texture.

Like all Simple products, our Booster Serum is dermatologically tested, non-comedogenic, contains no harsh chemicals that can upset your skin and is free from alcohol, mineral oils, artificial colours and fragrance. This Simple product is PETA approved vegan. Shake, drop, dab – it's that simple.

After using a cleanser, apply our non-sticky, non-greasy Booster Serum on its own 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 our hydrating 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 are incompatible when used closely together. If you'd like to use both in your skin care routine, we'd recommend using our glowing 10% vitamin C + E + F Serum Booster in the morning and then using our strengthening 10% Niacinamide (Vitamin B3) Booster Serum as part of your nighttime skin care routine. Keep calm and carry on caring for your skin.
