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. 🌟🌟🌟🌟🌟 Review: 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. ## Features - A lightweight Vitamin C Booster Serum.
