Medik8 C-Tetra Lipid Vitamin C Radiance Serum review
I tried Medik8 C-Tetra serum and here’s my honest, unsponsored review which you may find useful if you’re looking for a sensitive-skin friendly Vitamin C serum.
Medik8 C-Tetra Serum: the glow-boosting secret?
Medik8 C-Tetra is a vitamin C serum designed to restore skin radiance and even out tone. Its lightweight, fast-absorbing formula is formulated with 7% stabilised vitamin C, scientifically known as tetrahexyldecyl ascorbate.
This form of vitamin C is particularly effective because it remains stable over time, unlike traditional vitamin C which can lose potency when exposed to light, air, or heat.
The serum works to visibly smooth the appearance of fine lines and wrinkles, while also protecting against environmental damage caused by free radicals, aiming to bring you visible results after one week.
The ingredients behind the magic
The serum’s primary active, tetrahexyldecyl ascorbate, is a lipid-soluble, low-irritation form of vitamin C that penetrates the skin efficiently.
It supports collagen production and delivers antioxidant protection against harmful free radical damage, helping maintain a youthful appearance.
Vitamin E is included to boost the antioxidant capacity of the formula, protecting against premature ageing and enhancing the effectiveness of vitamin C.
Jojoba seed oil acts as a lightweight moisturiser, ensuring the serum is nourishing without feeling greasy.
Together, these ingredients provide a combination of antioxidant protection, hydration and anti-ageing support in a single formula.
Who is C-Tetra serum for?
This serum is for those looking to improve skin brightness, even out tone and support the prevention of fine lines and wrinkles, so virtually anyone in their late twenties to mid thirties!
Plus, the gentle formulation makes it ideal for sensitive skin and for anyone new to vitamin C serum.
Where to buy Medik8 C-Tetra serum?
You can conveniently order it online with free delivery via Medik8 official website or beauty retailers such as Cult Beauty, Lookfantastic or Space NK. RRP: £42
My Medik8 C-Tetra Lipid Vitamin C Radiance Serum review
When I first tried Medik8 C-Tetra, I was pleasantly surprised by the texture. Despite being an oil-based serum, it feels incredibly lightweight and absorbs quickly without leaving a greasy shine. The droplet format makes application simple and mess-free, which I really appreciate.
After using it every morning for two weeks, I could already see an improvement in radiance. My usually dull skin seemed brighter.
It was encouraging to notice a difference early on, but I know that the real difference will be in the long-run, and using ingredients like Retinol and Vitamin C in your daily skincare will pay dividends for decades to come.
Overall, I think C-Tetra is an excellent introduction to incorporating potent vitamin C into your daily routine and getting your skin used to it.
It’s gentle yet effective, and as my skin tolerated it well, I’m ready to upgrade to C-Tetra Advanced for an even stronger dose of antioxidant power.
