13 best Medik8 products for clearer skin, reviewed by beauty editors
Featured in this article
Medik8 is running a 20% off sale. I repeat: Medik8 – the science-backed skincare brand that's beloved by editors, Hailey Bieber and Rosie Huntington-Whiteley – has discounted almost every product on its site by 20% for a limited time only. Including Rosie's beloved R-Retinoate Cream. We are weeping.
When it comes to cutting-edge technologies, Medik8 are pioneers. TBH, they’ve been ahead of the curve for years now – despite its recent surge in popularity on TikTok and Instagram (cue: endless GRWMs and glass skin reveals). Beauty editors, dermatologists and A-list celebs have long been in on the secret, and based on results alone, it’s a secret worth knowing about.
The brand first made waves with its CSA Philosophy, coined by founder Elliot Isaacs back in 2009 – long before skin cycling or slugging were even a thing. The idea? That youthful skin could be ‘as simple as sticking to Vitamin C and SPF application by day, then Vitamin A (aka retinol) by night’. The best Medik8 skincare routines still reflect this.
Ahead, a full breakdown of the best Medik8 products for clear skin, plus a closer look at this CSA philosophy.

Why is Medik8 so good?
As the name suggests, Medik8 began its journey to stardom as a professional skincare line – not for use at home, rather in clinics, pharmacies and medical spas. As such, Medik8's OG formulations were put through their paces in strict clinical trials, assuring quality and efficacy. Everything they release today still gets tested in the same way.
What's more, Medik8 products – thanks to their clinical nature – typically feature higher concentrations of active ingredients than other over-the-counter skincare buys. Think: stabilised vitamin C for radiance, and retinal (Vitamin A’s cooler, more potent cousin) for smoothing. And thanks to smart delivery systems, actives go deep – so you’ll actually see results. These aren't just products that look good on your shelf.
Director of Research at Medik8, Daniel Isaacs said: “At Medik8, we emphasise the importance of science and research in our skincare products which are developed and made in the UK. We use premium, high strength active ingredients, and invest a lot of time and money into our in house product development.”
Dr. Mo Hamed (otherwise known as Dr Motox) – a leading industry aesthetics doctor – agreed. He told us: “Medik8 is my go to brand for most skin types. I love them because they combine clinical-grade ingredients with gentle formulations. This means all skin types can be treated with their products.”
What's new from Medik8 right now?
Medik8's latest launch is the C-Tetra Advanced – a vitamin C serum which our Beauty Director, Fiona Embleton, coined the best she has ever tried when she reviewed it ahead of its launch. She has road-tested over 200 vit-C serums, but deemed this one to be a rarity: delivering on the glow front but not irritating sensitive skin.
Following in the footsteps of Medik8's bestselling C-Tetra and C-Tetra Luxe, C-Tetra Advanced not only contains 20% stabilised vitamin C for brightening and hyaluronic acid for a moisture injection, but two other superstar ingredients to boot.
The first is plant exosomes – lipids that are extracted from plants – which have been found to encourage cell-to-cell communication, helping to repair damaged skin and reduce inflammation. In the Medik8 C-Tetra Advanced serum, the plant exosomes are from green tea. They encapsulate the vitamin C, carrying it deeper into the skin, while also having a soothing effect and protecting the skin barrier. So even sensitive skin or first time vitamin C users can avoid irritation from a high dose of vitamin C.
The second ingredient to know is acetyl zingerone. A super antioxidant, it boosts the power of your vitamin C to give your skin further damage against UV rays and pollution, too. Just note: this product isn't included in the 20% off sale.

How we test Medik8:
At GLAMOUR, we’ve spent weeks testing every Medik8 product in this guide – no quick reviews or first impressions here. Each one has been trialled by our beauty team across different skin types to see how it really performs day to day.
We assessed how the formulas feel, how they absorb, what they’re made of (hello, ingredient deep dives), and how they sit under makeup. We tracked real results like glow, clarity, and smoothness – and yes, we noted any meh moments too. Think of this as your honest, big-sisterly breakdown of what’s actually worth the hype.

Your Medik8 FAQs, answered:
What is the best Medik8 product for hydration?
According to Daniel Issacs, Director of Research at Medik8, “Total Moisture is a brilliant all-rounder for deep, long-lasting hydration without feeling heavy or greasy.”
He adds: “Built on Medik8’s H.E.O. technology (that’s humectants, emollients and occlusives working in perfect harmony), it keeps skin feeling nourished, supported and balanced. It also helps maintain a healthy microbiome, which is key for skin that stays calm and resilient.”
And the best Medik8 product for anti-ageing?
If we haven't convinced you to try Medik8's Crystal Retinol yet, we'll leave it to the experts to share why it's one of the best anti-ageing products on the market.
Dr Mo Hamed said: “Their Crystal Retinal range is innovative and far ahead for all other brands. Consumers can easily start at a very low retinal strength and build up overtime without having to worry about redness/dryness. The Retinal range is by far the best range by Medik8. I put all my clients not this range. It just works every time.”
The best Medik8 product for brightening?
Before the C-Tetra Advanced came out, which is the most super-charged vitamin C serum that Medik8 stocks, David Issacs told us that the C-Tetra Luxe – the brand's elevated take on vitamin C was the best product for brightening. And TBH, it's still very good.
“Powerful yet gentle and a standout for restoring radiance,” he told us. “With 14% tetrahexyldecyl ascorbate (a stabilised, lipid-soluble form of vitamin C) plus skin-conditioning squalane, it helps to visibly brighten and even tone while keeping skin nourished and comfortable. It’s the ideal choice for dull or lacklustre skin that needs a daily dose of glow, and it fits seamlessly into any routine.”
