I Tried 5 Vitamin C Serums and Found A Clear Favourite

Vitamin C serums reviewed, including the OleHenriksen Truth Serum and Drunk Elephant C-Firma Day Serum | The Good Living Blog #vitaminc #beauty #reviews #truthserum #drunkelephant

The world of skincare can be a very confusing one, especially if you’re just starting out. There is just so much information out there and it takes a lot of studying, a lot of poring over reviews to weed out what would work best for you. However, I think one of the miracle ingredients that almost all beauty experts agree on unanimously would be Vitamin C, especially when it comes to skin brightening and overall texture improvement.

When I started reading about and seriously investing in skincare about 15-18 months ago, Vitamin C was one of the first things I got into. Vitamin C is a champion antioxidant, and helps to combat against the free radicals that we are exposed to on a daily basis. It helps with the renewal and regeneration process of the skin, improves collagen production, boosts skin texture, and fades pigmentation marks over time.

Miracle ingredient, right?

Serums are concentrated skincare products, meant to deliver the powerful ingredients directly to your skin. You typically don’t require a lot of it, a pump or two of most products covers almost the entire face. They are typically used to address specific skincare issues.

So now when you put the benefits of Vitamin C and serum together, you know you’ve got a good thing going. The way I see it, Vitamin C serums are basically a godsend for uneven, dull skin, something that I could always use some help with.

Over the last few months, I’ve put several Vitamin C serums to the test. These have been across various price points, and I thought I’ll share with you all how my experience with each of them has been, in case you’re looking to add Vitamin C to your skincare routine.

The Ones That I Loved

OleHenriksen Truth Serum

I got the OleHenriksen Truth Serum as a part of the OleHenriksen 3 Little Wonders value pack. The reviews were all super positive I didn’t want to get my hopes too high. I needn’t have worried, really, because this stuff turned out to be pure gold.

It has a slight citrusy smell (which I loved, btw!), and a little does go a long way. One pump was enough for me to feel like I was covering my entire face. After using it for a few days, I felt like my skin had an even tone, and I could feel a glow without any oiliness.

Would I repurchase this? Absolutely!

Drunk Elephant C-Firma Day Serum

The Drunk Elephant C-Firma Day Serum is a really good Vitamin C serum but in my opinion, not the greatest. I’ve heard only the best things about the whole Drunk Elephant range, and was super excited to try this one.

I started using this after some gap of using any other Vitamin C serum, so my skin was definitely in need of some TLC. This Drunk Elephant serum turned out to be really good, and I could feel a difference in my skin texture within a week of using it.

Between the Truth Serum and Drunk Elephant C-Firma, I lean more towards the Truth Serum because it’s more cost effective ($50 versus $80 for 30ml) and the results were slightly better as well.

Would I repurchase this? No, but only because I have a cheaper alternative that works better.

Clinique Fresh Pressed Daily Booster with Pure Vitamin C 10%

This is a little different from any of the other products that I have rounded up today in that it comes packaged as only a seven day treatment. Given the fact that Vitamin C can be notoriously unstable, Clinique went ahead and developed a product that should be used for only 7 days. You could use it for longer, but the effectiveness of it would be suspect.

I picked up of 4-pack of the Daily Booster at the duty free store for $55 (a great bargain – it usually retails for about US$ 75 or so). This one is a quick worker – I mean, I could see a difference in my skin’s tone and texture almost by the end of the first pack. My skin felt brighter and more even, and I think it makes for a perfect travel companion.

Would I repurchase this? Yes, especially for when I travel, and if I get it at duty free.

The Ones That I Didn’t Like So Much

TruSkin Naturals Vitamin C Serum

This TruSkin Vitamin C serum was my first foray into the world of Vitamin C serums and I really, really wanted to like this one. It comes at a fantastic price point (only $19.99), and the reviews on Amazon were just so glowy and positive.

Unfortunately, after using it for several weeks, I couldn’t really feel like it made any difference to my skin. No evening out of the skin’s texture, no glow from within, nothing.

I found the serum slightly thinned out, but that didn’t bother me much to be honest. What did bother me though, was the tacky feeling after putting it on. It took about 3-4 minutes  for that tacky feeling to completely go away, and you know that’s a lot of time when you’re rushing to get ready for work in the morning.

Anyway, like I said, this one didn’t work for me at all, and since it didn’t make even the slightest bit of difference to my skin, I am not really keen to give it another shot.

Peter Thomas Roth Camu Camu Power CX30 Vitamin C Brightening Serum

July 2020 Update – This seems to have been discontinued now.

So around the time my bottle of the Truth Serum was getting over, I spotted this product on the Sephora website and it claimed that the Vitamin C used in this product was even more effective than other Vitamin C products, and being the skincare experimenter that I am, I decided to give this a try.

Well, let’s just say that this wasn’t a match made in heaven for me! Firstly, the smell! Oh my god, seriously what is with that fragrance! I am guessing it must have gone bad really soon, which only tells you how unstable this formulation was. Anyway, smell aside, my bigger issue was that just like the TruSkin serum, this one made no difference to my skin. The consistency is rather runny, and it leaves a bit of a sticky feeling on drying. On the whole, this one really didn’t hit the mark for me.

Safe to say that both of these won’t make the repurchase list.


My absolute favourite Vitamin C serum that I have tried would have to be the Olehenriksen Truth Serum, and if I am prepping for a big event, or if I am travelling, I would pick the Clinique Daily Booster. I’ve got my eyes on the Kiehl’s Vitamin C serum as well, maybe I’ll get that once my current bottle of the Drunk Elephant C-Firma Day Serum finishes.

What’s been your experience with Vitamin C serums? What’s been your favourite so far?

  1. Vitamin C is soo important, it’s one of my favorite ingredients. I currently use the Alpha H Vitamin C serum, but I’ve been eyeing the Drunk Elephant one as well. I fear my trip to Sephora will be a very expensive one:)

    1. Well, my husband is on a trip the US right now and you better believe that he’s been handed a MASSIVE shopping list! :)
