COSRX The Vitamin C 23 Serum 0.7 oz

[Employee of walmartcanada] Bottle cap was loose and lot of liquid spilled out in packing.

Remains sticky on skin long after applied. Mild unpleasant odor - didn't really mind it tho. Does not tighten the skin like other vitamin C serums. Would not recommend.

[This review was collected as part of a promotion.] I use the COSRX Line of skin care products exclusively and the Advanced Vitamin C 23 has been part of my AM skin routine for over two years now. I feel like it has really helped even my skin tone and it's great for my décolleté area, especially during summertime when sun spots begin to appear. I have had none since I started using this product.

[This review was collected as part of a promotion.] I honestly wish I had taken a picture of my skin prior to using your product. But let me tell you there is such a difference and I'm ecstatic. They finally I have found something that's gonna help. I have taken care of my skin, my whole life and within the last year, I have received horrible allergic reaction reactions that left scarring and this is devastating to me. A coworker shared your product and I had nothing to lose. I can't tell you how I feel seeing my face almost being back to normal the same clear skin that I have taken care of for so many years all I can say is thank you

[This review was collected as part of a promotion.] I have noticed a different in my skin since using this product. I have noticed the brightening effects. My skin tone is more even with less dark spots. While I do not store the product in the fridge one it is opened, I store my unopened products in the fridge. I made the mistake of leaving an unopened one in a cabinet. It evaporated within 2 months.

[This review was collected as part of a promotion.] I have used other Serum Vitamin C brands, when I first put this in a little goes a long way. My skin felt refreshed and hydrated. I've noticed my dark spots are somewhat lighter. My granddaughters remarked on how my skin glows. Truly a great and worthwhile product that definitely won't break the bank. l

[This review was collected as part of a promotion.] I really like the feel and texture of the Vitamin C serum. It feels light on my face. I have only been using it for 2 weeks so not sure if I'm seeing less discoloration in my face, but feel like all the products are making my face feel hydrated and soft.

[This review was collected as part of a promotion.] This is the 3rd time I buy this serum! Does it smell like cat food? YES… does it oxidize rather quickly unless it kept in the fridge? Also yes, very annoying. And yet I continue to buy, because it works that well on my skin.

[This review was collected as part of a promotion.] After using consistently I have started to notice my skin looking brighter and more even, and it gives me a really nice, natural glow without feeling heavy or greasy. Overall, this has been a great addition to my routine, and I definitely recommend it to anyone who has sensitive skin but still wants the benefits of Vitamin C.

[This review was collected as part of a promotion.] Use it every morning in my routine. I pair it with the alpha arbutin serum and it has made great results by evening out my skintone and lessing acne spots and scars. The serum feels great on my skin and not sticky at all. I suggest pairing it with the alpha arbutin serum for maximizing results of evening the skintone.
