Medik8 C-Tetra Advanced
C-Tetra Advanced by Medik8.
Say hello to your skin’s new daily defender. Medik8 C-Tetra Advanced is not your average vitamin C serum, it’s a next-generation, science-backed formula designed to defend against premature skin ageing and deliver accelerated visible brightening without compromising your skin barrier.
At the heart of this powerhouse formula is a clinically proven blend of 20% stabilised vitamin C and phyto exosomes, plant-derived messengers that help repair and protect your skin from environmental stressors like pollution, UV exposure, and oxidative stress. These stressors are the sneaky culprits behind early signs of ageing, and this serum is built to stop them in their tracks.
In just 7 days, users saw visibly brighter skin and a noticeable improvement in the appearance of wrinkles, with 0% barrier disruption. Yes, really, results without the irritation or dryness that often comes with high-strength actives.
The formula also includes acetyl zingerone, an omni-antioxidant that helps neutralise free radicals from all directions, basically giving your skin a shield against the modern world. Together, these advanced ingredients form a smart, synergistic complex that not only brightens but also smooths, strengthens, and protects.
Lightweight, fast-absorbing, and perfect for layering, Medik8 C-Tetra Advanced fits seamlessly into your morning routine. It’s ideal for all skin types, even those new to vitamin C or looking to upgrade to a higher-performance formula without irritation.
This is vitamin C, evolved. Medik8 C-Tetra Advanced delivers visible results, smarter protection, and daily support for glowing, resilient skin.

Love this, it may seem expensive but only a pea size amount on the sponge needed, fragrance lasts for hours
I've got really thick coarse stubble and I felt this did a great job of softening it up and protecting my skin.
Smells great, lasts ages, does the job👍🏼
Been using Harry’s products for a lot of years great products would recommend products
Was alittle reluctant to buy it at first due to cost but it lasts for ages making it worth every penny. So much better than any foam or gel aerosol. Very rich lather and a great citrusy smell.
Glad its back in stock, I have fine hair, dont have to wet handsand best applied to dry damp hair
So pleased to be able to order this toothpaste as I hear that it may be discontinued. Has immediately fixed the degradation to my gums that was occurring as a result of chemotherapy. Best toothpaste. Get some while you can.
I am very pleased with this. The toothpaste seems to leave my teeth really clean and has a pleasant taste - not minty, just slightly floral.
Strong effective, Don't be over generous with how much you pour into the bath. It is effective with only a little and you feel so much better after a soak in it. In the hot weather I thought a little poured into a bowl and soaking tired swollen feet in it helped a great deal. It is easy to put too much in as the consistency is light but you really do need a small amount only.
Highly recommended for aches and pains
Very fast delivery, arrived in a lovely presentation box. Smells like a manly fragrance for which I get a lot of compliments
Item as described. Extremely quick delivery. Thank you very much!!!
