Medik8 is one of the high-quality brands loved by skincare lovers no matter their skin type.
Today, I’m delving into the Medik8 C-Tetra line which offers an alternative form of Vitamin C called Tetrahexyldecyl Ascorbate.
These products have taken the skincare market by storm and for good reason.
In the following sections, you’ll find a Medik8 vitamin C review for three separate products:
- Medik8 vitamin C cream review
- Medik8 vitamin C serum review
- Medik8 vitamin C luxe serum review
About Tetrahexyldecyl Ascorbate
Before we dive into the reviews and find out which Medik8 vitamin C product is right for you, let’s take a brief look at Tetrahexyldecyl Ascorbate.
This is a lipid-soluble derivative of Vitamin C, which allows it to penetrate the skin better than L-ascorbic acid.
It is less irritating, more stable, and helps in brightening, collagen boosting, and fighting free radicals without the common stinging sensation of the regular Vitamin C. For more details on this amazing ingredient, make sure to refer to my previous post.
Medik8 C-Tetra Day Cream Review
Let’s dive right into the first Medik8 vitamin C moisturizer review.
The Medik8 C-Tetra Day Cream is an all-in-one cream that aims to provide the benefits of Vitamin C while moisturizing the skin.
This skin-brightening and anti-aging product is formulated with Tetrahexyldecyl Ascorbate and antioxidants, allowing it to visibly brighten your complexion and diminish the look of wrinkles, revealing a youthful, radiant glow.
Enriched with hyaluronic acid, this lightweight formula provides intense hydration, leaving your skin smooth, supple, and illuminated for a dewy, youthful appearance.
The cream is available in a jar of 1.7 oz or 50 ml for $53.
Features:
- Combines hydration with the antioxidant properties of Vitamin C and Vitamin E.
- Comes in a creamy yet lightweight texture, which is quickly and easily absorbed by the skin.
- You’ll notice a reduction in the signs of premature aging as soon as the first week of active usage.
- The moisturizer layers well underneath SPF and makeup.
Who is this for:
- This product is a must-try for those who seek a simplified, minimalist skincare routine, with no additional steps — this one can substitute any serums you may use beforehand.
- Great for all skin types, but especially for normal, dry, combination skin, and skin that can’t handle pure l-ascorbic acid
Who is this not for:
- I wouldn’t recommend this moisturizer to people sensitive to fragrances as this product contains perfume and several essential oils.
- People with oily skin can find this a bit heavy.
Keep in mind that Medik8 also offers a C-Tetra Cream with SPF protection, which adds another layer of convenience if you’re exploring different avenues to minimize steps in your skincare routine. It has an even stronger power against free radicals and dark spot correction.
Now that we’ve covered the Medik8 C-Tetra vitamin C day cream review, let’s move on to the brand’s serums.
Medik8 C-Tetra Serum Review
The C-Tetra healing serum is designed to give you smooth, radiant skin. This nourishing Vitamin C product is perfect for beginners, providing daily use for glowing, refreshed skin.
Suitable for all skin types, even the most sensitive, it effectively reduces visible signs of aging, such as wrinkles and fine lines, while reviving dry or crepey complexions.
You can find it in a bottle of 1 oz or 30 ml for around $45.
Features:
- Contains Tetrahexyldecyl Ascorbate for enhanced skin penetration and stability.
- Targets signs of aging, brightens the complexion, and boosts collagen production in the deep layers of the skin.
- A lightweight and fast-absorbing formula that layers well with other products.
- Again, you’ll see the first fading of spots in about a week of consistent use.
- The spreadable formula ensures that just three drops are enough to cover your entire face and neck, making it more economical than water-based vitamin C serums.
Who is this for:
- Those new to Vitamin C and looking for an easy-to-use serum.
- People with a preference for lightweight skincare products wanting to build a quick routine.
Who is this not for:
People with highly sensitive skin may find the limonene and the grapefruit peel oil in this formula slightly irritating.
Medik8 C-Tetra Luxe Serum Review
The final product featured in my Medik8 Vitamin C-Tetra review is the Luxe Serum.
Medik8 C-Tetra Luxe Serum is an upgraded version of the C-Tetra Serum, with a more luxurious feel due to its squalene base.
It offers ultimate hydration and rejuvenation for folks with dry skin. Formulated with a potent blend of hyaluronic acid and vitamin B5, this lightweight serum provides intense moisture and nourishment to quench even the thirstiest of skin.
You can purchase it in a bottle of 1 oz or 30 ml for around $70.
Features:

- Has the ultimate luxurious feel to it and applies like a charm!
Who is this for:
- People experienced with Vitamin C and looking for a more advanced and luxurious formulation.
- People with dry skin as the squalene base provides additional hydration.
Who is this not for:
- Those who prefer lightweight formulas.
- People with skin sensitivities who can’t handle essential oils and fragrances.
What percentage of vitamin C is in Medik8 products?
Medik8 doesn’t always disclose the exact percentage of vitamin C in their line. The Medik8 C-Tetra Luxe contains 14% Tetrahexyldecyl Ascorbate, but there is no information about the concentration of the ingredient for the other two products in this article.
Which medik8 vitamin c serum is for you?
If you are new to using Vitamin C, the Medik8 C-Tetra Serum would be a good start. For those who are more experienced and seeking a richer experience, the Medik8 C-Tetra Luxe Serum would be ideal.
