Multitaskers are always welcome in our busy lives. Powerful skincare all-rounder, niacinamide, stands out for its versatility and ability to treat any skin type with kindness (from dry skin to oily and sensitive skin). Our new booster serums are lightweight formulas powered by high-performance ingredients at high concentrations to supercharge your skin care routine for instant, visible results. 10% niacinamide (vitamin B3) hydrates, smooths and helps to strengthen and protect your skin barrier. 1% vitamin B5 minimises pores and softens the appearance of fine lines and wrinkles. Like all Simple products, our booster serum is dermatologically tested, contains no harsh chemicals and is free from alcohol, mineral oils, artificial colours and fragrance. What's more, this Simple booster serum is PETA approved and vegan, with 95% naturally derived ingredients.
