Antioxidant vitamin C gets glowing reviews for good reason. It’s naturally brilliant at brightening your complexion and protecting against environmental aggressors like pollution and blue light. Our new Booster Serums are powered by high-performance ingredients to supercharge your skin care routine for instant, visible results. Packed with 10% active ingredients, this booster contains 2% of a skin-kind derivative of vitamin C that won’t irritate your dry skin (or sensitive skin). 1% vitamin E boosts the effectiveness of the vitamin C and nourishes your skin while 7% vitamin F moisturises and strengthens your skin barrier. Containing 95% naturally derived ingredients, it's safe for every skin type. Our kind to skin promise? 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 perfume. This Simple product is PETA approved vegan. Shake, drop, dab – it's that simple. After using a cleanser, apply our non-sticky, non-greasy serum alone or mix a few drops into your favourite moisturiser for a super-quick vitamin C boost. Oh, and it’s fab under makeup too. Try cocktailing our 10% Vitamins C + E + F Booster Serum with our 3% Hyaluronic & Vitamin B5 Booster Serum (a few drops of each) in the morning and don't forget your SPF afterwards. The best part? Real people love it. 83% agreed their skin felt instantly smoother and softer and 8 out of 10 liked how the Booster Serum felt. The stats don’t lie, so try it yourself – we always love to know what you think of our new products so leave us a review.
