timeless 20% C+E+Ferulic Aci Serum review

It happens. Every. Single. Time.

Whenever I review a Vitamin C serum, inevitably someone asks, “how does it compare to Timeless 20% C+E+Ferulic Acid Serum?”

Short answer: it’s great dupe for pricier options like Skinceuticals CE Ferulic and Paula’s Choice C15 Booster. But the super high Vitamin C content makes me think twice before recommending it to everyone.

Long answer: read the review below.

What’s In Timeless 20% C+E+Ferulic Acid Serum?


L-Ascorbic Acid is the pure form of vitamin C, a powerful antioxidant that:

If you’re serious about antiaging, you need this baby in your skincare routine. But be careful! L-Ascorbic Acid has a couple of side effects you should be aware of:

  • Unstable: It goes bad quickly when exposed to light and air. Timeless guarantees its effectiveness for only 3 months. Buy it only when you’re ready to use it daily. If the serum has turned brown, it’s too late. It’s useless. Throw it away!
  • Irritation: High concentrations of L-Ascorbic Acid – especially at the low pH (below 3) it needs to work its magic – can irritate skin, especially if it’s sensitive.

Irritation is the reason why I don’t recommend Timeless 20% C+E+Ferulic Acid Serum to just anyone. I have clients who can use 15% Vitamin C without problems, but the second they up their dose, their skin turns into a red, flaky mess.

The trick to using Vitamin C is to start small. Begin with a 10% concentration, move on to 15% and then upgrade to 20+% doses. Even then, if your skin is sensitive, it may not like anything above 10-15%.

Both Skinceuticals CE Ferulic and Paula’s Choice C15 Booster use 15% Ascorbic Acid. For most people, that’s more than enough. But if your skin can take the extra load and you’d like to save some $$$, Timeless 20% C+E+Ferulic Acid Serum is a great step forward.

Vitamin C is an antiaging superstar, but that doesn’t mean it should play alone. Studies show it works even better when paired with fellow antioxidants Vitamin E and Ferulic acid.

Ferulic acid itself is an antioxidant on steroids. While most antioxidants only destroy one type of free radicals (that’s why I always say, the more the merrier), ferulic acid fights THREE different types on its own! How cool is that?

But it’s when paired with Vitamin C that Ferulic acid (and Vitamin E) really shines. Here’s what they do together:

  1. They boost one another’s effectiveness (they don’t become ineffective as quickly as they would on their own)
  2. They enhance your sunscreen’s protection, helping you fight sun damage and premature wrinkles

Whatever Vitamin C serum you go for, make sure these two are in it, too.

Sodium Hyaluronate is a form of Hyaluronic Acid, a moisture magnet on steroids.

Hyaluronic Acid attracts moisture into the skin and binds it there. It’s so powerful, it can hold up to 1000 times its weight in water!

All that extra moisture plumps up your skin, makes it softer and gives it a dewy glow.

Timeless 20% C+E+Ferulic Acid Serum has a lightweight liquidy, slightly oily (blame it on the Vitamin E) texture that sinks in almost immediately.


The scent isn’t the best. Timeless didn’t add any fragrance, so what you’re smelling is the ingredients. Let’s just say Ferulic acid doesn’t exactly smell of roses! But if you can get past that, the results are worth it.

How To Use It

Every morning, under sunscreen to boost its sun protection.

Performance & Personal Opinion

Let’s be honest here: even the best antiaging ingredients won’t boost your collagen or fade away your dark spots overnight. That’s why I’ve been using Vitamin C every day in my skincare routine for the past 10 years.

As my skin is used to Vitamin C, Timeless 20% C+E+Ferulic Acid Serum simply maintained the status quo. It keeps my skin firmer and my complexion glowing.

If you’re newer to Vitamin C, you’ll see a bigger improvement – at least in terms of brightness – fairly quickly. Keep using it consistently and it’ll improve the texture of your skin and help you age more slowly.

I can’t imagine doing without my daily fix now.

Who Is This For?

Women with resistant skin who are serious about anti-aging.

Who Is This NOT For?

  • Sensitive skin – 20% L-Ascorbic Acid is too harsh for you
  • Oily, acne-prone skin – L-Ascorbic Acid may aggravate acne


Timeless has packaged the serum in a blue dark bottle that keeps it safe from light. But air can still get through and spoil the formula whenever you open the bottle (it has a pump dispenser). Unfortunately, it’s rare to find a Vitamin C serum that doesn’t use this type of packaging, so use yours quickly!

P.S. The new bottle is a bright yellow, but the formula inside is still the same.

Does Timeless 20% C+E+Ferulic Acid Serum Live Up To Its Claims?

Brightens dull complexions. True.
Corrects hyperpigmentation and discoloration. It certainly helps with this, but don’t expect results quickly.
Provides protection against environmental stressors. True.
