Simple Smooth+ 10% Niacinamide (Vitamin B3) Serum is an advanced skin care solution designed to achieve visibly smoother, more even-toned skin in just 2 weeks. Powered by SkinTwin* science, this revolutionary skin-mimicking technology works with your skin’s biology, mirroring its natural repair processes to improve skin texture and tone.

Formulated with 10% niacinamide, our face serum promotes cell turnover** and helps restore your skin’s natural, even tone. Complemented by 1% vitamin B5, it hydrates your skin for a softer, smoother feel, while 1.5% vegan glycerin protects against dryness to improve skin elasticity.

Our niacinamide serum is clinically proven to deliver results. Users reported visible improvements in skin radiance within just 1 week, and a refreshed and hydrated feel with every use. 90% agreed their skin appeared more glowing and felt velvety soft. It’s your solution to achieving skin that feels and looks beautifully smooth and even.

Shake, drop, dab – it’s that simple. After using a cleanser, apply our face serum alone, or mix a few drops into your favourite moisturiser. Oh, and it’s fab under makeup too. Try cocktailing it with Simple Hydrate+ 3% Hyaluronic Acid + Vitamin B5 Serum. 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, we recommend applying our Glow+ 10% Vitamins C + E + F Serum in the morning and then using the niacinamide serum as part of your nighttime routine.
