When it comes to skincare, not all ingredients are created equally, but one consistently earns its place at the top of the beauty hall of fame: vitamin C. Brightening, smoothing, and seriously glow-inducing, it’s the powerhouse my skin can’t live without, especially when it's delivered via a hard working serum. My skin is often dull, dry and quite lacklustre, which is why a vitamin C serum is key in my routine. My favourite is from Medik8, the brand that’s mastered the art of fusing high performance active ingredients with science informed by dermatologists. If you’re after radiant skin and a routine that works as hard as you do, this is the name to know.
It goes without saying that, as a beauty writer, I get to try an abundance of skincare when it lands on my desk; as soon as I tried Medik8, I was hooked. The Medik8 ethos is to keep skincare simple and effective with specific ingredients, and I've discovered it works to maintain radiance and hydration in my skin. What I also like is that Medik8 offers products with ingredients of different strengths, which allows your skin to build up a tolerance to actives like vitamin C or retinol.
One vitamin C product that caught my attention was C-Tetra Luxe, which the brand describes as a product to brighten, add radiance, reduce wrinkles and tone discolouration. Vitamin C is known for restoring glow and this serum has a more powerful, stabilised strength suitable for all skin types. For those new to the world of vitamin C in skincare, the original C-Tetra is one to have on your radar.

With 14% of vitamin C, this velvety serum offers deep nourishment and hydration as the potent ingredient gets to work to reduce the appearance of pigmentation, tone and dark spots. The rich, oily texture feels luxurious and nourishing without pilling under moisturiser, SPF or make-up.
Pros
- Rich, oily texture
- Infused with vitamin E and jojoba to provide nourishment
- Great for all skin types
Cons
- Might be too intense for some beginners

Why do I love this vitamin C serum? For me, I instantly see a boost of radiance and plumpness immediately after application and with continued use. The potent ingredient worked to improve dark spots, fine lines discolouration, but primarily solved my issue of dull-looking skin and added some much-needed glow. I originally started with C-Tetra and graduated up to Luxe after a couple of months. My skin reacts well to vitamin C but, for beginners, I would suggest starting with a lower percentage to build up your tolerance. Medik8 advises that both C-Tetra and C-Tetra Luxe are suitable for any skin type, including the most sensitive. I apply this serum in the morning before moisturiser and SPF, and my skin loves the oily texture. I crave a radiant finish, and this serum provides me with the confidence to go make-up free.
Consider this serum your gateway into Medik8 - from Press & Glow to the Crystal Retinal range, this brand knows exactly how to get me obsessed with products that fuse skincare science with salon-worthy results.
