C-Firma™ Fresh Day Serum - Sérum de Dia

Great for the skin

I received this product complimentary for review, and I’ve been testing it consistently in my morning routine. The C-Firma Fresh 15% Vitamin C Serum feels thoughtfully formulated, especially with the fresh-mix packaging that keeps the vitamin C potent. I appreciated being able to activate it myself — it gave me confidence that the formula was fresh and effective. The texture is lightweight and slightly creamy, not watery. It absorbs well after a minute or so and layers nicely under moisturizer and sunscreen. I didn’t experience pilling when pairing it with other products, which is a big plus. After a few weeks of use, I noticed my skin looked brighter and more even overall. It helped reduce dullness and gave me that healthy glow, especially around my cheeks. My complexion looks more refreshed in the mornings. I also appreciate that it includes antioxidants beyond vitamin C, which makes it feel like a well-rounded protective serum. One thing to note: it has a mild, natural scent (typical of vitamin C serums), but it fades quickly. If you’re very sensitive to texture or scent, that’s something to keep in mind. Overall, I think this is a great option if you’re looking to add a powerful vitamin C to your routine for brightness and antioxidant protection. I would recommend it to anyone wanting smoother, more radiant-looking skin.

I had super high hopes for this product. But it immediately broke me out like crazy and I have amazing skin so it was not what I was expecting. So needless to say I will not be using it again. Also I expected a decent size product but it was a mini size

Great vitamin C product. It didn’t irritate my acne prone skin, zero negative reactions. This serum is lightweight and absorbs really quickly. My skin felt a little sticky and tightened at the beginning but once you apply the moisturizer this feeling is gone. I like this product and can recommend if you like vitamin C products

Love

I really enjoyed this product because I felt like it was soothing enough for my skin. It’s tough sometimes to find a resurfacing serum that doesn’t irritate your skin and performed very well for me and didn’t irritate my skin

I recently tried this C-Firma Fresh 15% Vitamin C Day Serum and I loved the whole concept idea of mixing the product myself. I loved that it doesn’t have a strong scent. It absorbed quickly into my face and I felt a mild tingling effect which It makes me believe it’s working. I loved how I noticed my face looked more brightened and glowing.

My new everyday skincare

Absolutely love this serum and how it was so light weight. It left my skin glowing and I could see a difference in my skin within a few days. I have been reaching more and more for this item everyday. It’s in my everyday go to skincare bag

It’s soooo good!

Okay I really love this. It’s super lightweight, sinks in fast, and doesn’t mess up my makeup at all. My skin looks brighter and just healthier overall, and it hasn’t irritated me. Would totally buy again!!

I absolutely love the C-Firma Fresh Vitamin C Serum from Drunk Elephant — it’s become a staple in my skincare routine! This serum instantly brightens my complexion and helps fade dark spots without irritating my skin. I adore the fresh, invigorating scent and how lightweight it feels while soaking in quickly and leaving my skin looking radiant and glowy. Over time, I’ve noticed a real improvement in texture, firmness, and overall brightness — it’s like a daily boost of sunshine in a bottle!

You have to mix the liquid part with the powder, it’s easy, but it seems like a marketing technique. The formula is nice and liquid rather than creamy, and it absorbs easily. It caused no irritation. However, I can’t speak about the long-term results since this is only a 4 ml sample. When I use this serum, my skin looks brighter and even. Nothing dramatic though, compared to other similar products, for example I’ve used the e.l.f. Vitamin C serum, and I find it very similar to this one.

Interesting product

This was different in the sense that you have to mix the two products together to use. I did like that there wasn’t a strong scent and it did not irritate my skin. I would recommend this for anyone who likes drunk elephant.

Great daily Vitamin C for a healthy glow

I received this product complimentary in exchange for my honest review. I’ve been using the C-Firma Fresh 15% VITAMIN Day Serum in my morning routine and I’m really impressed. I love that you mix it fresh yourself because it feels more potent and effective. The texture is lightweight, absorbs quickly, and layers perfectly under moisturizer and SPF without feeling sticky. After consistent use, my skin looks brighter, more even, and has a healthy glow. It’s a great daily vitamin C option, especially if you’re looking for something gentle but effective for everyday use.

Love it

I love a good vitamin C moment in the morning, and this one makes my skin look alive. It gives that subtle glow without feeling sticky. I’ve been using it under sunscreen and makeup, and it just makes everything sit better. My skin looks brighter and more even over time. It’s one of those products that makes you feel like you’re taking care of your skin in a more intentional way.
