Hyaluronic acid is our hydrating, power-plumping miracle for youthful-looking skin. Our new Booster Serums are powered by high-performance ingredients to supercharge your skin care routine for instant, visible results.

This hydrating serum is a real multitasker; along with locking moisture into dry skin, improving skin texture and reducing fine lines, it also relieves irritation, making it the perfect partner to calm dry or sensitive skin. Packed with 3% active ingredients (95% of which are naturally derived), it contains 0.5% active hyaluronic acid, 0.5% active PENTAVITIN™ and 2.5% active provitamin B5 – the dream team for soft, plump skin.

Our kind to skin promise? Like all Simple products, our Booster Serum is dermatologically tested, non-comedogenic, contains no harsh chemicals and is free from alcohol, mineral oils, artificial colours and perfume. This Simple product is also PETA approved vegan.

Shake, drop, dab – application is that simple. After using a cleanser, apply our non-sticky, non-greasy formula alone or mix a few drops into your favourite moisturiser to give dry skin a super-quick hydration boost.

Oh, and it’s fab under makeup too. Try cocktailing it with our 10% vitamin C + E + F Serum Booster in the morning (remember your SPF) and 10% Niacinamide (B3) & B5 in the evening – it goes well with both, but make sure you use them at different times (niacinamide and vitamin C get on better when they're used separately).

The best part? Real people love it. 81% agreed their skin felt instantly soft, 80% said it looked healthy and 3 out of 4 agreed it felt instantly hydrated. The stats don’t lie, so try it yourself – we love to know what you think of our new products so leave us a review.
