This may be the most expensive serum we tested, but the elegant packaging and high dose of vitamin C (15%) helps justify the price.

After the trial period, our panel were unanimous in saying skin felt firmer, with some noticing a reduction in wrinkles too. Overall, this lightweight serum delivers where it matters — improving skin tone, texture and overall radiance.

Part of Elizabeth Arden’s capsule collection, these biodegradable pods contain a luxurious dose of oil-soluble vitamin C, which is designed to hydrate skin.

With plenty to cover the face, neck and décolletage, this was the best serum on test for its hydrating properties, with all agreeing the effect was instant and long-lasting. The silky formula was an ideal base for makeup application and the majority saw scarring and pigmentation fade.

With a pleasant tightening and firming effect, our testers could feel this one getting to work immediately. The creamy texture felt hydrating but never greasy – ideal for sensitive skin – but it took a little while to fully absorb.

The majority saw an instant brightening effect, which lasted impressively throughout the test. They also liked the intuitive dispenser, which gave the perfect amount of formula to cover the whole face. A luxurious option for all skin types, and beautifully packaged to boot.

We know it’s what’s inside that counts, but our panel was won over by the technical-looking pump packaging here. Part of Murad’s Vita-C range, this serum contains real gold, which has been proven to have a stabilising effect on active ingredients such as vitamin C, in turn making it more potent. The formulation also boasts the exfoliating properties of glycolic acid for better absorption.

Although suitable for all skin types, some testers noticed slight tingling during the first couple of applications, so if you’re new to vitamin C you might want to work your way up to the recommended twice daily dosage. The brightening effects were noticeable though, with the more seasoned vitamin C users being particularly impressed.

It's hardly a secret that fermenting food is akin to supercharging it with nutrients — the benefits of ingredients are amplified and concentrated by the process. It follows, then, that adding powerful ferments to an already concentrated vitamin C serum will only enhance its effects.

This lightweight formula, featuring brightening yeast ferment and pigmentation-targeting molasses ferment, proved our theory correct. Easy to spread and quick to absorb, it left our panel’s skin feeling smooth, radiant and plump with a long-lasting dewy glow.

Paula’s choice it may be, but if you’re after a dark spot fader and anti-ager combined, then this might also be the best choice for you. It's packed with powerful antioxidants such as ferulic acid, which help protect the skin against free radicals and keep the 15% vitamin C content stable.

Testers loved how the dropper packaging allowed them to create a custom dosage based on their skin’s needs; simply add a drop or two into your moisturiser if you don't fancy adding another step to your skincare routine. Many found it hydrating and agreed that it boosted radiance, firmed up skin and evened out their tone. For mature skin, it’s worth the money.

The selling point of this punchy serum is its ability to deliver all the hyperpigmentation-busting results, without the skin barrier disruption.

“According to many doctors and dermatologists I’ve met, they’re seeing a rise in their clinics of issues related to damaged skin barriers,” says Florence Reeves-White, senior beauty writer for the GHI. “This launch is designed to tackle this trend, where people are piling on potent retinols and actives without figuring out what’s right for their particular skin type.

“Due to its gentle formulation, this is my new favourite vitamin C serum, especially when used in conjunction with retinols that can be tough on the skin barrier, that all-important first defence.”

This brilliant brightener is lightweight, absorbs quickly, and doesn’t leave any residue. “I didn’t realise I needed a vitamin C serum until I tried this one from Korean skincare brand, Tatcha,” says Maddie Evans, lifestyle writer for the GHI. “

After using it consistently for a few weeks, I started to notice a real difference in my usual lacklustre complexion. My skin tone is much more even now, and evidence of old blemishes in the form of dark spots vanish much quicker.” Maddie’s also a fan of the accompanying eye cream, which leaves tired eyes looking fresh and bright.
