These days potent Vitamin C Serums are all the rage, and Drunk Elephant’s C-Firma Day Serum is an award winning super potent formula that combines Vitamin C with the powerful anti-aging ingredient ferulic acid to diminish the appearance of lines, wrinkles, sun damage, and hyperpigmentation in one go.

Aren’t we all looking for that product jammed full of so many powerful ingredients (that’s still safe for the skin) that’s like an anti-aging and brightening skincare cocktail on steroids?

That’s the only way to describe Drunk Elephant’s C-Firma Day Serum.

Enriched with ascorbic acid, Vitamin E, essential nutrients, pumpkin ferment, fruit enzymes, and a powerful antioxidant complex- this product is a real all in one daily go to.

If you’re looking for something powerful, that will work quickly, now, and deliver results fast (in terms of anti-aging and brightening), Drunk Elephant’s Serum is the way to go.

Review: Drunk Elephant C-Firma Day Serum

Drunk Elephant’s C-Firma Day Serum has quickly grown in popularity and become and award-winning bestseller, so I was curious to find out if it was truly hype or just another Vitamin C serum available on the market.

After trying it out and reading through its incredible ingredient list, its pretty safe to say C-Firma is definitely in a class of its own.

Aren’t we all looking to cross off the following checklist with any serum or new face treatment? Brightening, gets rid of acne marks, anti-aging benefits, restores radiance, makes your entire face glow, anti-acne, and helps with sun spots/damage and pigmentation issues?

With Drunk Elephant’s C-Firma Serum, you can cross off all your checkpoints and then some, plus it leaves your skin feeling like it just took a huge gulp of water after being in a desert for days.

But really, this is likely one of of the best skincare products I have tried and is more than just a regular or “trending” Vitamin C Serum. The other ingredients leave your skin looking smooth, fresh, and glowing, and the product stays active on the skin for 72 hours.

The benefits are pretty unreal, and I noticed a difference in the look and feel of my skin within a few days of use. The texture was soft and did not feel greasy or sticky at all, and this is one of those products I would recommend everyone at least try to sample if you can’t afford it at the moment- it’s really that good.

If you can make the splurge, a little amount goes such a long way that it lasts for months and benefits continue to improve over time.

This has to rank number 1 out of all the Vitamin C treatments I’ve tried yet, and there is some tough competition.

Drunk Elephant C-Firma Day Serum Pros and Cons

Here are a look at some main pros and cons to bear in mind prior to purchase with C-Firma Day Serum:


  • Anti-aging benefits: with daily use of the C- Firma serum, you can expect to see a reduced appearance in fine lines and wrinkles, firmer skin
  • Cruelty-free company: company does not test on any animals, does not use any animal product during any manufacturing processes, or in any product formulations
  • This potent blend of Vitamin C and Ferulic Acid is one of the best quality and most effective serums per price point you can get for your money (very active ingredients)
  • Feels refreshing and brightening benefits are visible after first time use
  • Works for acne scar marks and pigmentation
  • Does not feel greasy, sticky, or heavy on the skin during application
  • Enhances the effectiveness of any used sunscreen by 4 times
  • Can help improve the appearance of dark circles under the eyes (use gentle around eye area)
  • Amazing anti-acne benefits: I noticed an incredible reduction in the appearance of acne marks and future breakouts with the use of this serum
  • Overall, the serum supports healthier, younger, glowing, and more vibrant looking skin that glows with restore radiance and helps in repairing previous damage
  • Company supports the  IEF (International Elephant Foundation) and other charities
  • Even with very sensitive and acne-prone skin, this is the first ferulic acid product I have been able to use without any irritation, redness, rash, breakouts, or marks following use
  • Winner of Allure’s Best of Beauty products (general, not category specific)


  • Price point: the $80 range is certainly quite steep for any skincare product, however considering the potent ingredients contained in this product and how effective it is in real results (and how little product is needed), if you can afford to splurge, this is the one product that truly tops the serum list, and go for it- it is so worth it

Drunk Elephant C-Firma Day Serum: Worth It Winner?

In one word, yes.

We found Drunk Elephant’s C-Firma Day Serum was absolutely worth it for its price, because it is truly that effective in treating multiple signs of aging, pigmentation issues, acne scar marks, and restored signs of vibrance and glow- all in one product.

We’re all looking for that perfect item to use as a go-to without the need for 20 other steps, and with C-Firma, we’ve finally found it.

This is a new staple product, and it’s so much more than just your average Vitamin C serum. It combines a powerful blend of anti-aging ingredients with other extracts to work (very quickly) to literally erase the signs of time on the face while preventing future damage from forming.

So when you’re looking for a fresh glow, younger appearance, and a treatment that works aggressively and very quickly but can still be used on sensitive skin, this is my number one recommendation in the blended Vitamin C serum category.

It is hands down a worth it winner, and highly recommended!
