Good stuff is hard to come by and I really would have loved for C20 Original Pure Vitamin C20 serum to be featured as a holy grail write-up. I mean, how often do you find a product that can fade age spots within a month? And not forgetting the perks of making you fairer and more even-toned?
Sadly, C20’s miracle potion comes with a condition – a big one. Read on to find out if C20 is for you.
About C20 Original Pure Vitamin C20 Serum
C20 Original Pure Vitamin C20 Serum is a Korean-made product that consists of 20% active Vitamin C. As with all Vitamin C serum, people rely on it to brighten skin tone and fade off skin discolorations such as age spots or pigmentation. Vitamin C can also boost skin collagen that indirectly leads to reduced fine lines and pore size.
- Updated: C20 has since been rebranded as Tiam My Signature C-Source. All ingredients and formulation remains exactly the same.
I’m happy to see that the more potent ingredient ‘Ascorbic Acid’ is used. This is however a less stable Vitamin C and oxidize more quickly than other vitamin C derivatives.
In terms of her branding, C20 Original Pure Vitamin C20 Serum promises to “refine, brighten, balance, and tone skin for a radiant appearance”.
As a standard sizing, you get 30ml of high-strength vitamin C serum that comes with a refreshing scent similar to that of a freshly-peeled orange.
For my order placed on 25 March, the Vitamin C serum that arrived at my door was freshly manufactured on 16 March and has a one-year expiry.
What’s Good about C20 Original Pure Vitamin C20 Serum?
1. Fades Age Spots Quickly
My age spots were visibly lightened within a month or two. I was amazed as such spots weren’t easy to fade even with chemical peels. My skin tone was definitely brighter and more radiant.
Thumbs up to C20 Original Pure Vitamin C20 Serum!
2. Not that Sticky
Before buying C20 Original Pure Vitamin C20 Serum, I was busy combing through online reviews to see if it was worth a try. Many said it was VERY sticky and that put me in a great dilemma because stickiness reminded me of the worst overnight mask I’ve ever used – so bad I had insomnia.
Today, I’m happy to report to all that this serum is not all that sticky. The mild stickiness would last no more than a minute or two. After that, your face would feel just like how it would be after putting on a layer of light lotion. C20 has alcohol in it, so it helps the serum to dry up on the face quickly.
3. Easy to Apply
The clear serum has a good ‘slip’ and two drops were more than enough to cover my face and neck. The liquid is quite thick in consistency and hence easy to apply without experiencing any drippage. This is unlike the highest-rated Vitamin C serum on this website which has a water-like consistency.
4. Quality Packaging
C20 Original Pure Vitamin C20 Serum comes in a darkly-tinted dropper-style bottle that was airtight to prevent the potent yet unstable Ascorbic Acid (Vitamin C) from oxidizing.
My serum which I’ve been keeping in the fridge is still as clear as water after more than 2 months.
5. So Cheap!
I bought it for only S$13.50 from Qoo10, excluding a shipping fee of $3.50 to Singapore. This is by far the cheapest 20% vitamin C serum I’ve tried. Not just that, a 30ml bottle would be able to last me for a very long time, I predict.
At the 2 month mark, I’m only through 20% of the serum. Based on extrapolation, the whole bottle may last me for at least 10 months. Hopefully by then, the serum hasn’t turned orange or brown.
Oh…and not to forget, they even sent me 3 free samples. Not bad for a $13.50 purchase, huh?

What’s Bad about C20 Original Pure Vitamin C20 Serum?
1. OMG. Bad Breakout
On the first day the bottle arrived, I applied C20 Original Pure Vitamin C20 Serum over cleansed face at night. The next morning, I woke up with fresh pimples on my face.
I’m prone to pimples and do breakout from using wrong products. But this must be one of the more severe breakouts I’ve had in a long while since my teenage years. Pimples appeared in weird places such as eyebrow, neck and corner of nose. I hardly get pimples on these areas.
Mind you, these pimples were the active type, which means they were painful upon touch. Not the kind you can easily scrap off like nothing has happened. Luckily, the full breakout subsided after a few days of usage. After that, I would still have a handful of pimples as long as I’m still using this serum.
2. Persistent Pimple Problem
When I thought my skin has grown accustomed to C20 Original Pure Vitamin C20 Serum, I received another full-blown breakout. That was after I returned from a short overseas trip (3 days only) and restarted the regimen. It was then another one whole week of purging. Sad.
3. Inconvenient for Exercise Addicts
If you work out a lot, please remember to wash off this C20 Original Pure Vitamin C20 Serum before sweating it out. I didn’t and went out for a jog one day. The next morning, I woke up with a face full of pimples (again).
Other than the pimple issue, another problem with washing face before a jog is how drying it can be for the skin. Washing off facial oil that serves as natural emollient and then jogging against the wind isn’t that great an idea.
So far, the only Vitamin C product I’ve tried that doesn’t require me to wash my face before a jog is Glo-therapeutics Cyto-luxe Vitamin C+.
4. Dry Patches
It’s great that C20 Original Pure Vitamin C20 Serum doesn’t sting on application. However, I can’t say it’s gentle on the skin because I get dry patches on my skin, especially near the temples.
Alcohol, a drying agent is listed as the third (most) ingredient, after water and Ascorbic acid. Vitamin C has been known to be drying. Adding alcohol to it probably makes it worse.
Perhaps that’s the reason why I don’t witness the collagen-boosting and firming effect I get from other brands of Vitamin C serum. My skin is looking dehydrated.
When to Apply?
The instruction advised that you apply C20 Original Pure Vitamin C20 Serum every night after cleansing and toning.
I tend to use this in the morning instead as Vitamin C can protect our skin from the sun. Use it under a layer of sunscreen to get double the protection.
Note: Vitamin C is not a sunscreen replacement.
Without the pimple issue, C20 Original Pure Vitamin C20 Serum would have been a 5-star rating for its effectiveness in evening skin tone and fading age spots. And not forgetting its very attractive pricing. Unfortunately, it isn’t great for my pimple-prone skin. For those who have never been bugged by pimples or who have normal to oily skin, this could be a godsend to you. Obviously, I’m out of this category and would likely not repurchase C20 serum. Rating: 3.5/5
