Meet our Booster Serums

You’ve got your skincare routine for one thing: to help your skin look and feel its best. Among all the things you can do to achieve that, there’s one extra-clever way that will make all the difference: using skin serums.

What is a serum?

We thought you’d ask that. Well, a serum for skin gives your skin exactly what it needs, wants and craves – whether that’s more hydration, improving strength or minimising pores.

The great thing is serums are lightweight formulas powered by high-performance ingredients, which means they’re easily absorbed by your skin but deliver all their goodness deep down. What’s more? They do it all without causing any irritation, so they’re perfect for sensitive skin.

How do I go about using a serum? 

Because skin serums are such powerhouses, it only takes a few drops of one to let it do its job. Using the pipette, squeeze a few droplets into your hand. Let it warm up slightly so it doesn’t shock your skin, then dab onto your freshly cleansed face. It’s as simple as that. After that, be sure to lock in the goodness with your favourite moisturiser.

Which serum should I use and why?

Using skin serums is a great way to supercharge your skincare routine. Our NEW Simple Serum Boosters are powered by high-performance ingredients that treat your skin without irritation, and each one has particular benefits, which we’ve pulled out for you below.

Simple Booster Serum 10% Niacinamide (Vitamin B3) 

This is a fantastic multi-tasking booster, a skincare all-rounder that’s versatile and has the ability to treat any skin type with kindness (from dry skin to oily and sensitive skin). Our niacinamide serum hydrates and smooths your skin and helps to strength your skin barrier while it’s at it. And that’s not all – with its 1% Vitamin B3, this serum also minimises pores and softens the appearance of fine lines and wrinkles.

Simple Booster Serum 3% Hyaluronic Acid & Vitamin B

Meet the soft-skin dream team – 0.5% active hyaluronic acid, 0.5% active PENTAVITIN™ and 2.5% active provitamin B5. Beautifully hydrating, softening and soothing, this serum also regulates sebum production (so your skin doesn’t get too oily), improves skin texture and relieves irritation. A true multi-tasker.

And that hyaluronic acid in its formula? Well, this power-plumping miracle molecule binds up to 1000 times its weight in water. That means youthful-looking skin. Your skin’s never had more of a perfect partner than this anti aging serum.

Simple Booster Serum 10% Vitamins C + E + F

For something that covers all the skincare bases, here’s just the ticket. This serum contains 2% of a skin-kind derivative of vitamin C, that won’t irritate your dry skin (or sensitive) skin, 1% vitamin E that boosts the effectiveness of vitamin C and nourishes your skin, and 7% vitamin F, that moisturises and strengthens your skin barrier. It’s a 10% that goes a long way when it comes to brightening and firming your skin and makes this a truly one-of-a-kind serum for skin.

Like all Simple products, our Booster Serums have been dermatologically tested, and they’re PETA approved and vegan, with 95% naturally derived ingredients.

All part of the routine

Now that we’ve spotlighted each of our Booster Serums and you know what they’re all about, we’ll paint a little picture of what your mornings and evenings would look like, with them as part of your skincare routine:

Your morning routine

There’s no better way to start the day than with some hydration and glow. For that, a little 3% Hyaluronic Acid & Vitamin B5 followed by 10% Vitamins CEF will do the trick. Don’t forget to apply your broad-spectrum SPF before you leave the house.


Your evening routine

Skin needs extra replenishment at night which is why we recommend combining 3% Hyaluronic Acid & Vitamin B5 to deliver deep hydration along with 10% Niacinamide to strengthen and even tone while you sleep.


Showing your skin kindness and bring some serum skincare into your daily routine. It’s beautifully simple to do so. Find out more about each of our serums here.
