It’s been 3 years since I last shared this Review on Timeless 20% Vitamin C Serum. I’ve sầu gone on to repurchase another bottle, and thankfully, it is now available in Singapore. The biggest difference in the new purchase is the entire repackaging – from a blue-tinted glass bottle lớn a yellow plastic pump bottle.

More about Vitamin C Serum & its Benefits

Not sure if you guys have sầu heard of the popular and expensive Skinceuticals CE Ferulic. It has almost similar formula as Timeless Vitamin C Serum, but cost many times more. Today, I’ll make a general comparison between the two and you can then decide if you lượt thích to try the very-much-cheaper Timeless Vitamin C Serum.

Prior to that, let’s talk more about why someone would want khổng lồ use a Vitamin C Serum & how to lớn go about choosing one. Read on.

Vitamin C Serum & its Benefits

I’ve sầu shared in an earlier post about why I thought Vitamin C Serum should size an integral part of one’s skincare regimen. In a nutshell, Vitamin C Serum is great in brightening skin tone and regenerating the collagen in our skin.

Those with pigmentation or aging skin would benefit the most from Vitamin C serum.

How I Search for a Great Vitamin C Serum?

Unfortunately, most Vitamin C Serums available in retail stores are expensive sầu, especially if they contain Ascorbic Acid instead of Vitamin C derivatives. I was doing quite a bit of retìm kiếm & found that many cheaper Vitamin C Serum – especially those available on Amazon – contain Sodium Ascorbyl Phosphate, which is a less preferred (by me) but more stable khung of Vitamin C. 

And many also contain alcohol or witch hazel, which really isn’t all that great when added to the potentially-drying Vitamin C. It took me some time khổng lồ find one that comes with Ascorbic Acid, contains no alcohol/witch hazel và is affordably priced. Not an easy feat, okay?

Let’s find out more about Timeless 20% Vitamin C Serum and see if it does its job well.

Marketing Claims by Timeless 20% Vitamin C Serum

Timeless 20% Vitamin C Serum as its name suggests contains 20% of Vitamin C form, which in this case is L-Ascorbic Acid. It also contains Vitamin E and Ferulic Acid which are ingredients said lớn help extover the life & effectiveness of Vitamin C.

I was surprised & happy to see that Timeless 20% Vitamin C Serum also contains hyaluronic acid in its formulation.

Timeless also mentions that the serum can:

Even skin tone and help build collagen Brightens dull complexionsCorrects hyperpigmentation và discolorationProvides protection against environmental stressors

Let’s see if Timeless 20% Vitamin C Serum is able to meet all four of her claims!


What’s Good about Timeless 20% Vitamin C Serum? 

1. Easy to lớn Apply

Applying Timeless 20% Vitamin C Serum was a breeze! The solution while watery was easy to lớn apply because it has a slight slip to it. This not only makes it easy khổng lồ ‘pick up’ the liquid with your finger tips, but also lớn spread it easily over the face.

As you can see from the photos below, Timeless used khổng lồ operate by way of a dropper. Today, it uses a pump bottle making application even more convenient. However, one trade-off is that you are not able to lớn customise the quantity per application. 

For my small face, I found the dispensed amount slightly more than what I would need. But that’s fine as it forces/reminds me khổng lồ apply it all the way across my neông xã và décolletage.

2. Comfortable và Weightless After-feel

As expected, Timeless 20% Vitamin C Serum with its rather watery solution feels lightweight and comfortable on the skin.

Immediately upon application, there was only a slight stickiness. Wait a brief moment và the skin absorbs the serum beautifully leaving no grease & stickiness. In fact, the skin feels like bare skin, but without the tightness. Vitamin E in this formula could have sầu helped provide skin with the initial hydration witnessed during application.

Update (May 2021): The above sầu was documented in 2018 và continue khổng lồ apply lớn the new bottle I’ve sầu purchased in 2021, in terms of consistency and after-feel. 

3. Brighter Skin Tone

I started using Timeless 20% Vitamin C Serum in January 2018. After one month, I noticed that my skin was fairer, more translucent and glowing with radiance. My age spots that appeared after turning 30 have lightened – some spots faded more than the others. Let’s go through one by one on the blown-up before-after photos. The AFTER photos were taken on the 3-month mark.

Update (May 2021): The following Before-After observations were made in 2018. In 2021, I did not make such photo comparison, but bởi vì notice brighter and fairer skin. Hope it’s not placebo effect. :) 


This spot on my chin has lightened albeit not very significantly. 


I am happy with the lightening of this spot near my eye. It should be gone in no time, I hope. 


This very faint spot near my brow has also faded so much I can hardly see it on the AFTER photo lớn.

4. Didn’t Trigger Pimples

It is comtháng for some Vitamin C Serum to trigger pimples. In fact, 60% of Vitamin C Serum I’ve tried caused me khổng lồ breakout. Timeless 20% Vitamin C Serum surprisingly didn’t which came as a surprise because I’ve read that products containing vitamin E may trigger pimple breakouts. 

If you wonder, the 2021 yellow bottle also does not give me pimple problem. 

5. Affordably Priced

As compared to lớn SkinCeuticals C E Ferulic Vitamin C Serum, Timeless has very similar formulation in 2018, as shown below.

Timeless: Water, Ethoxydiglycol, L-Ascorbic Acid, Propylene Glycol, Alpha Tocopherol, Polysorbate 80, Panthenol, Ferulic Acid, Sodium Hyaluronate, Benzylalcohol, Dehydroacetic Acid.Skinceuticals (2018): Aqua / Water / Eau, Ethoxydiglycol, Ascorbic Acid, Glycerin, Propylene Glycol, Laureth-23, Phenoxyethanol, Tocopherol, Triethanolamine, Ferulic Acid, Panthenol, Sodium hyaluronate


In 2021, I can no longer find SkinCeutical’s exact ingredient menu online. The only thing I can see is 15% pure vitamin C (L-Ascorbic Acid), 1% vitamin E, and 0.5% ferulic acid.

So, yes, we vì chưng notice a lower vitamin C percentage (15% vs 20%) as compared to Timeless. If you can find the latest ingredient danh mục, bởi let me know, k?

Price Comparison: SkinCeuticals vs Timeless Vitamin C Serum

SkinCeuticals C E Ferulic Vitamin C Serum is priced at US$166, many times pricier than Timeless 20% Vitamin C Serum which is priced at US$27 (see latest online price).

Singaporeans, good news! It’s somewhat surprising that we can get it cheaper in Singapore (via Shopee). I ordered it for just SGD25 (30% cheaper và no need to lớn worry about delivery cost).

Don’t forget to lớn get your Shopee $10 Credit if you are a new user.

This prompted me to give sầu Timeless 20% Vitamin C Serum a try in 2018 before potentially venturing khổng lồ the more popular SkinCeuticals CE Ferulic Vitamin C Serum. I mean, if a significantly lower-priced sản phẩm can vị the job well, then why waste the money, right? 

6. Quite Stable for an Unstable Ingredient 

Timeless website indicated the serum as having a shelf life of just 3 months. I’m happy to lớn report that my first bottle in 2018 was still Trắng and clear even after 6 months. One thing I did was lớn keep it in the fridge right from the beginning. I believe this has helped slow down the oxidation process of Vitamin C Serum.

In 2018, I had depleted only one-fifth of the serum after 3 months of usage. Let’s see how long this 2021 bottle can last since each pump dispenses more quantity. 

7. Not Over-Drying khổng lồ Skin

Now, this is another difference between the 2018 and 2021 observations. A few years ago, I’d written that Timeless Vitamin C was dehydrating though I had also highlighted that it got less drying over time (after a few months).

In 2021, I did not notice significantly drier skin right from the start of application. Great, isn’t it? 

Update (2022): The sản phẩm was drying towards second half of usage – maybe solution was more concentrated towards the kết thúc.

What’s not good about Timeless Vitamin C Serum? 

1. No Visible Firming

Timeless had shared that Vitamin C Serum could build collagene và in 2018, mentioned that it could make skin firmer. Unfortunately, I did not notice any skin-plumping or firming effect, both in 2018 & 2021. 

Update (2022): For info, SkinCeutical’s Vitamin C serum seems to offer skin firming effect. Read full review here.

How to lớn Apply Timeless 20% Vitamin C Serum? 

Timeless used khổng lồ advise twice daily application, & I’d shared then that Vi-Ta-Min C serum shouldn’t need multiple application as it can last at least a day on the skin. Furthermore, multiple application a day could exacerbate skin irritation. 

In 2021, the instruction has changed to lớn once a day và Timeless recommends evening application. If you prefer daytime application, Timeless asks that you follow up with a sunscreen.

2021 application instructions

Personally, I prefer morning application as that was an advice from my aesthetic doctor…that doing so can ensure maximum benefit when UV exposure is at its peak. Here’s an extract from self.com:

…vitamin C becomes less effective sầu when exposed to light, so it’s important khổng lồ give it time lớn absorb inlớn your skin before going outside… You don’t need lớn wait a specific amount of time—as long as it’s absorbed, you’re good to lớn go. ~ self.com

Timeless 20% Vitamin C Serum (2018)


In 2018, after 3 months of usage, I was still looking forward to opening my fridge & taking out the cold bottle of Timeless 20% Vitamin C Serum khổng lồ apply. In 2021, it’s the same! :)

I love sầu its comfortable after-feel, proven ingredient (Ascorbic Acid), great price & skin-brightening effect. I also appreciate that it’s safe khổng lồ use on my pimple-prone skin. 

But still, I’m keen khổng lồ try the more expensive sầu SkinCeuticals, just to lớn be sure which is better (Afternote: I did – here’s the review). :) Rating: 4.5/5
