[REVIEW] Drunk Elephant C-Firma Day Serum


In early 2018, I wrote a review regarding the sample of this C-Firma Day Serum that included in the Drunk Elephant Rise + Glow Duo set. At that time, I realized that the packaging of the sample size is not as hi-tech as the full size one, that caused the Vitamin C from the sample size is easily oxidized (tons of people were complaining in the Insta, so, really, I wasn’t the only one). On that review I told you that I will give another chance to the C-Firma Day Serum once I have a chance to visit a country that does have Drunk Elephant’s official reseller. Who knows God suddenly decided to give me a chance to visit Australia not long afterwards? Life is funny and full of surprises, really! 😉


A super-potent vitamin C day serum packed with a powerful antioxidant complex, essential nutrients, and fruit enzymes, all working together to firm and brighten the appearance of skin, while improving the signs of photoaging.

This revolutionary serum, jam packed with a potent antioxidant complex of 15% l-ascorbic acid, 0.5% ferulic acid and 1% vitamin E, plus other formula-supportive enzymes and antioxidants helps neutralize pollution, environmental stressors and damaging free radicals while replenishing lipids and visibly reducing the appearance of dark spots and wrinkles. Uniquely formulated with pumpkin ferment and pomegranate extracts, C-Firma™ enzymatically dissolves dead surface skin cells for smoother texture. Sodium hyaluronate crosspolymer quickly penetrates skin and provides intense hydration. The result is a noticeably diminished appearance of photo damage, replaced by incredible radiance and luminosity.

C-Firma™ has a reservoir effect, which means it will stay active on skin for up to 72 hours and cannot be washed or rubbed off. C-Firma™ has a pH level of 3.3 – 3.5, which Drunk Elephant believes is the key to a non-irritating, effective formulation that delivers real results.

IMPORTANT: C-Firma™ contains pure L-ascorbic acid and is best when fresh, so USE IMMEDIATELY and DON’T STOCK UP!


Because I have to use it directly because it’s best to use when fresh, I immediately use it after I got back from Sydney. And I have to say that even after the first application, this serum already impressed me. It significantly brightened my tired face, as well as brightened the acne scars on my skin. Moreover, I can’t get enough of its citrus scent, so juicy and fresh! The texture is pretty liquidy, and it absorbed really fast into the skin.

I also love that this serum would work well if I use it alongside another products! I love the combination of this serum and J.One Jelly Pact for the day time underneath makeup (a lot of people complimented my skin whenever I use this combination!) and I also love the result of using Drunk Elephant C-Firma Day Serum for day time and Dr. Wu Mandelic Acid for PM routine, the result is the acne scars would brightened in lightning speed, and smaller pores! Love, love, love!


Will I recommend this product? Yes, yes, a hundred of time yes!!!! This Drunk Elephant C-Firma Day Serum is definitely worth the hype. It would brightened your overall skin, your acne scars, and all. It would also work well with a couple of other products and ingredients! It’s really fun to play with, plus the hi-tech packaging that helps to avoid the formulation to be easily oxidized also packaged with uber cute packaging and branding! No wonder a lot of people been loving this serum. ❤

  1. I just ordered the duo with c firma in it! So are you saying the products didn’t act as well for you or mostly that it oxidized or expired quicker since the bottle isn’t the same? Thank you xx


    1. Mine was oxidized because the sample size isn’t as airtight as the full size one. (I’ve seen lots of similar cases in instagram as well, though). But hopefully you will be lucky and get a great one! 🙂 I heard that DE will be happily change it for you if you got the bad one, so maybe if you live in the US, you could do that! (Unfortunately I live far, far away, so I couldn’t exchange mine)


      1. Ohh okay that’s very good to know! I had no idea the quality of the bottles were so different. I have heard they do have excellent customer service! Will be sure to keep that in mind! xx
