COSRX Pure Vitamin C 13% Serum with Vitamin E & Hyaluronic Acid, Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 0.67fl.oz/20ml, Korean Skin Care

This serum has a lightweight texture, absorbs quickly, and leaves the skin feeling smooth and refreshed. Excellent quality.

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.

This is a great serum that goes on beautifully and makes my face much brighter. The initial smell during application is a bit odd. It's not a terrible smell, but not a great one either. Fortunately it quickly goes away as the serum dries and does not linger! Only downside is that since this product suggests being refrigerated after opening is that I am more likely to forget this step in my skincare routine since it is in the kitchen rather than the rest of my products.

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.

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. 🌟🌟🌟🌟🌟

Overall I love the Cosrx brand. The holy grail for snail mucin and their all-in-one cream is amazing. Figured I give this serum a go. Why not? Contains: super vitamin E + hyaluronic acid. Item arrived in a timely manner. Packaged well, no damage to box. Opened it up and threw item away. It smelled like tuna fish oil. Gave it 3 star because of the brand name. Very disappointing as I was hyped to incorporate into my daily skin care routine.

I’ve been purchasing this Vitamin C 13% serum for maybe 7,8 bottles so far. It’s gentle and hydrating, and it really makes my skin brighter and clearer. After opening, I store it to the fridge to keep it fresh.

Estoy fascina con los productos de Skincare Coreanos, han cambiado mucho mi piel

Perfect

This is my 2nd purchase. I really like this brand.

My go to vitamin c serum I love the effectiveness and how gentle it is on my skin. Unlike other vitamin C serums, this one doesn't irritate or cause breakouts. It provides amazing value for money and keeps my face feeling moisturized and smooth all day.

Ho acquistato il prodotto su consiglio di un'amica e devo dire che mi piace davvero molto, abbinato ad una media-buona skin-care fa piccoli miracoli di luminosità e compattezza!

Great product as my friend she is make up artist recommended
