NOTE: This serum is now known as Medik-8 C-Tetra and is available in a barely completely different bottle. However the method inside is similar, so every thing nonetheless applies.

Assessment up to date on 29/04/2024.

What’s the very best Vitamin C spinoff on the market?

Yeah, yeah, ideally we must always all use pure vitamin C (L-Ascorbic Acid). However that’s irritating as hell. Unstable AF. Goes dangerous earlier than you attain half the bottle and stings your pores and skin like loopy.

Give me a spinoff, pronto!

However, which one? There are greater than a dozen today, all promising the identical advantages as pure vitamin C with out the uncomfortable side effects. How have you learnt which one actually delivers?

Personally, I’m a fan of Tetrahexyldecyl Ascorbate, the spinoff utilized in Medik8 C-Tetra Serum. Right here’s why:

What’s In Medik8 C-Tetra Serum?

TETRAHEXYLDECYL ASCORBATE TO BRIGHTEN SKIN

Let’s be sincere: Tetrahexyldecyl Ascorbate (TA) isn’t as highly effective as L-Ascorbic Acid. But it surely does two issues means higher than it:

  1. Stability: It doesn’t oxidise (i.e. go dangerous) as rapidly when uncovered to mild and air (learn: you may truly end the bottle!).
  2. Penetration: Whereas L-Ascorbic Acid solely penetrates the dermis (uppermost layers of your pores and skin), TA penetrates each the dermis and the dermis (the deeper layer under it).

TA is so good at penetrating pores and skin as a result of it’s one of many few types of vitamin C that’s oil-soluble. And that immediately catapults it to the highest of the vitamin-C-derivates-to-try listing.

However, what the heck does it do as soon as it penetrates pores and skin? Research say it:

  1. Brightens the complexion
  2. Fights the free radicals that trigger wrinkles
  3. Boost collagen production

The catch? These research are performed through the use of both excessive concentrations of TA (20%>) or by combining decrease doses (8%>) with L-Ascorbic Acid.

Medik8 C-Tetra ONLY makes use of 7% Tetrahexyldecyl Ascorbate.

Don’t get me incorrect. I’m not saying this focus is simply too low to work (I did see an enchancment, as I’ll share in a while on this assessment).

However at this focus, that is extra of a preventative serum for ladies of their late 20s/early 30s. If you wish to fade darkish spots or cut back wrinkles, you’re nonetheless higher off with L-Ascorbic Acid.

Another factor: vitamin C works better when used together with vitamin E and ferulic acid. This serum solely has vitamin E. Not a biggie. It’ll nonetheless do its job nicely. I simply needed to say it for many who are searching for all 3 antioxidants of their serum.

JOJOBA OIL TO MOISTURISE SKIN

I do know what you’re pondering: “I’ve oily pores and skin so something with oil is out of the query.”

Usually, you’d be proper. But jojoba oil is one of the exceptions to the rule. Why?

Out of all of the oils, jojoba oil resembles sebum (your pores and skin’s pure moisturiser) extra intently. This implies it’s light-weight sufficient to sink rapidly into your pores and skin and never worsen pimples.

Plus – and that is excellent news for ALL pores and skin sorts – jojoba oil is wealthy in fatty acids that moisturise pores and skin and increase its moisture content. 

Translation: it moisturises pores and skin with out leaving a greasy, pimply mess behind.

Enjoyable reality: jojoba is pronounced “ho-ho-ba”.

GRAPEFRUIT PEEL OIL TO… IRRITATE SKIN?

I’ll be transient. Grapefruit peel oil is right here solely to make the serum scent citrusy (as a result of how else do you count on vitamin C to scent like?!).

Downside is, its aromatic elements might irritate delicate pores and skin. There’s solely a drop of it right here, although, so it’s unlikely to be problematic for every other pores and skin sort.

I’ve been utilizing it for weeks and I didn’t expertise any irritations. Though I nonetheless desire my skincare fragrance-free, I’ve to confess I like how this serum smells. 🙂

  • Yellow: There’s not a lot proof it really works (at the very least, but).

Texture

Light-weight texture that sinks into the pores and skin actually rapidly. I swear you’d by no means say the bottom is an oil!

Perfume

Technically, it’s fragrance-free. Medik8 didn’t add any separate perfume to it. Perfume can irritate pores and skin, so it’s all the time good to go away it out. However then, you might have a product that does an incredible job at stopping wrinkles, however you don’t wish to use it cos it smells like crap.

The workaround? Medik8 added grapefruit oil, an important oil that provides the serum a subtly summery citrus scent. However, the aromatic elements that make this oil scent wonderful also can irritate delicate pores and skin.
