Can recommend for others to try
I have very sensitive skin, but this serum works just fine for me. I have only started for a week so too early to tell if it’s effective.

Very well packaged
I wasn’t going to review this for a while bc I just got it. However, I had to comment on how well it’s packaged. Specifically the bottles seal. My husband was with me when I twisted it open & made the audible “wtf”. It sounded like I was opening a fresh, tiny soda😂 I’m guessing since the vitamin C is pure it’s causing a release of gases when opened. I’ve used countless serums in little glass bottles over the yrs, including vita c. From $10 up to $150 in price. Not ever has a product been so well sealed. And that’s actually the most important part of skincare packaging. I’m impressed. I can say already that I like the way the serum feels. You think it’s going to be an oil when you’re dripping it on & applying it. Then it starts feeling like a cooling water. As it dries down it gets a little tacky. Once I put moisturizer over it the tackiness went away. And I can report that the bottle continues to make the spphh sound every time you open it. So, it has a 10/10 in packaging, imo.

Liquid Sunshine in a Bottle
I’d like you to meet officially my glow dealer. I put her on, and it’s like someone turned the brightness up on my face without making me look oily or fake — just pure, radiant, even skin.She’s lightweight, sinks in instantly, and doesn’t give me the dreaded sticky or stingy drama that so many vitamin C serums bring to the table. Within weeks, my dullness is GONE & my redness? Fading. My entire complexion? Smooth, even, and practically sparkling. I look like I’ve been sleeping eight hours and drinking green juice (spoiler: I haven’t).This isn’t just brightening — it’s transformative. My morning routine feels incomplete without her, and when I skip a day, I can tell. She’s will forever live in my mini fridge rent free.She’s the reason I’m glowing like I actually have my life together.

SCAMMED/DAMAGED
Clearly been tampered with. Immediately taking out the box the bottle felt light and I shook it around to see if anything was even inside. It felt like nothing was in there, so I poured it in a measured beaker glass to verify if it matched the correct amount of ounces and sure enough it’s been emptied. Be careful ordering this because the bottle is black so there is no way to verify if anything is inside without pouring it out.EDIT: upon further review I think the package has been leaking at first I thought that was the design on the box but it’s actually the product that has been spilled

Lo he estado usando junto con la niacinamida de la misma marca y me encanta cómo deja mi piel hidratada y con mis poros más chicos, llevo 1 mes usando este combo.

I really like this product. It works wonders on my skin (28M), brightens it and make it more even.Just be aware that the texture is very watery and not “gel-like” at all. The smell is also pretty strong and surprising, not very pleasant, but it goes away once dried so I have nothing to complain about.

香りはツナ缶ですが、私は慣れてしまって平気です。塗ると翌日顔がふっくらします。冷蔵庫に冷やしてお風呂あがりに塗るのがおすすめです。

The COSRX Pure Vitamin C 23% Serum has quickly become one of my favorite brightening serums. It’s strong enough to make a visible difference in dullness, uneven skin tone, and fine lines, yet the formula feels balanced thanks to the addition of vitamin E and hyaluronic acid.I noticed my skin looking fresher and more radiant within a few weeks, and with consistent use, my complexion feels smoother and more even. The texture is lightweight, absorbs well, and doesn’t leave a heavy or sticky finish.If you’re looking for a powerful yet hydrating Vitamin C serum, this one really delivers. Just remember, like with all skincare, patience and consistency are key to seeing lasting results.
