I love the ingredients in this vitamin c! I’ve been using it daily since the beginning of December and my skin glows more than it did before adding it to my routine. It smells good and feels great; cooling as it’s going on, a bit tacky after it’s rubbed in, and smooth when it dries. A second bottle is already in my fridge waiting to be used.

UPDATED 12 July 2024 (TL;DR below):
I think this serum was one of the first products I found using SkinSort’s filters, and it had caught my attention because it kept showing up- even with my ultra-specific filtering! I was looking for a beginner-friendly, non-irritating Vitamin C product. Finding this felt like I’d hit a gold mine. (I was so excited I bought two the first time buying it!) Comes in a classic dropper bottle and, to my standard, is on the pricey side for the quantity you get.
According to Cocokind themselves, this serum will brighten, hydrate, and even out my skin. I mean, yeah, pretty much! The aloe vera juice base is very sensitive skin-friendly and does well with making your skin feel protected and nourished. It does leave your face feeling kind of sticky, but it wasn’t a problem when I applied the serum on semi-wet skin. (That only applies to those who apply their skincare products back-to-back with no pauses in between, which isn’t *really* the way to go.)
The brightening and evening effects of this serum deserve its own attention. I’m actually not giving credit to Ascorbyl Glucoside, which is the Vitamin C derivative highlighted in this serum. The underdog takes the cake in this one: the one, the ONLY… Azelaic Acid!!! I think without it this formula would really fall short. Maybe it’s working overtime because it sorta works in synergy with Vitamin C? (Not 100% sure that applies to derivatives as well…) Either way, I LOVE IT. In just a week, my PIH (i.e. post-inflammatory hyperpigmentation, the stubborn dark spots you get after your pimples go away) started fading..? My skin was brighter..? Me, with my crazy dull skin, waking up to glowing, inflammation-free skin?!?! What kind of *sorcery* is in this?!?!?! (Azelaic acid. c:)
Despite my improved complexion, this serum didn’t quite work in the same way many Vitamin C serums are touted for (i.e. complete skin regeneration). It was more of an acne serum? Which I appreciated, of *course*… but it’s also not why I bought the serum. Yes, it did brighten my skin (and get me loads of compliments!), but my breakouts weren’t any less frequent. It just kind of cleaned up the mess afterwards. Again, can’t be bothered by that, but my goal with this was to heal my compromised skin barrier as a whole. This product was a drop in the bucket. Well, maybe a splash.
Maybe my skin has simply become too resilient for the gentle likes of Vitamin C derivatives… a blessing or a curse? 🤔
TL;DR: Great for brightening PIH (post-inflammatory hyperpigmentation), azelaic acid is the SUPERSTAR in this- not so much the Vitamin C, thick and sticky, very sensitive skin-friendly :)
Old review:
Very gentle. Love the aloe vera base, suitable for all skin types. Been using mostly consistently for a few months and have seen improvements in hyperpigmentation.

Cured my acne scars
I had mix feelings when I first bought this as I read that the smell can be off-putting. But I am glad I bought it. My acne scars faded a lot more after 3 days of using it and saw great results in one week. It also didn't break me out despite containing alcohols and oils. It does sting a little on the first application but doesn't irritate my skin. The smell can be quite strong when you first spread it on, but it slowly goes away after awhile.
