Much to my surprise!
I’ve been back and forth with skin care for years. From pricey brands to more affordable brands. My last purchase of vitamin c serum was from skinceuticals. Super expensive and although it was ok it certainly isn’t worth the price. I use the snail mucin from cosrx and I really like it, so I decided to try the vitamin c 13 from cosrx. They also have a vitamin c 23, but I wanted to try the 13 first. Like many of the reviews mention it does have a “fishy” smell to it, but it doesn’t last for long. I’m on the 5th day of using this and I can’t believe it. I can see a difference. My skin is brighter and softer in just a few days. I’ve never with any other skin product have seen results so quickly. I do believe I’ve finally found a good vitamin c serum that I’m gonna stick with and like I mentioned this is the 13%. When this is gone, I’ll order the 23%. I do recommend starting with the 13% to avoid any skin irritation and then move up to the 23%. I am a little bummed out because it took me a long time and alot of money before I was able to find cosrx, but now that I found it, I’ll continue to use it. I highly recommend and shout out to cosrx for making awesome skin care products affordable. 🌟🌟🌟🌟🌟

Wow
This vitamin C serum has made my face smooth bright and moisturized. The small bumps on my face have slowly gone away. I like the way it makes my face feel moisturized throughout the day. Some people say it feels oily, and it does feel like an oil when you first apply it but then it dries to a natural finish with a slight tacky moisture film, but not at all oily. Some might feel it is oily because they apply too much. I like the way it dries down personally. Feels like the way a gel cream might feel when it absorbs. The smell is not great, but not horrible because it disappears once it dries. To me it smells like copper and burnt orange peels. I would buy this again because I like the results.

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.

VERY POTENT PRODUCT!! Will give almost instantaneous results but use correctly.
Background: I’m not a skin care expert and am not a skin care professional. But I’m someone who recently got into skin care for myself. I have uneven skin tone and dull looking skin. In my 30s, brown skin, and I seldom use any makeup.About Vitamin C and this product:Vitamin C is great to even out skin tone and make it bright. This one is a very potent Vitamin C serum – it is 13% vitamin C. To put that into context, most starter vitamin C serums and creams are 10%. But this concentration suited me well and I saw results almost from Day 1. A little goes a long way, don’t need to apply too much. Within 2 weeks most of my dark patches were gone and my skin was glowing. After 1 month of use I even stopped using makeup altogether even while going out. In short it worked great for me.The catch:Do remember, this is acidic (Ascorbic acid). And it is pretty concentrated at 13%. If you have sensitive or thin skin, this should NOT be the first thing you should apply on cleansed face. Use a toner or anything which can repair skin barrier before using this serum. Otherwise it can cause extremely dry skin, irritation and redness. I use the Cera Ve hydrating toner. Also follow it up with a good moisturizer to prevent skin from drying. If you are going out in the sun then sunscreen is a must, otherwise this will do more harm than good. Don’t overdo it, applying it once a day and like a serum (few drops) should be enough. Look out for patches of redness and dried skin when using, it is usually means you are overdoing it and need to back off a little. Use a night moisturizer to calm the skin – that worked for me.

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.

Nice consistency
I like the consistency of this vitamin C serum. It’s watery and soaks into the skin very quickly, doesn’t leave alot of stickiness afterward like some others I’ve used. It has a slight unpleasant odor which doesn’t linger but it may bother some users. It’s very important to read the small user guide included in the box because this serum must be refrigerated after opening in order to maintain it’s freshness and efficacy.

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.
