COSRX - The Vitamin C 13 Serum

I’ve not used this serum long enough to see results but it’s light and gentle in the skin and works well under makeup

Es ligero, aclara las manchas y da una sensación de una piel sana

love the texture abd smell. I alternate this and the C 23. I lile them both… I think the best ones on the market. Way better than a lot of other overhyped products on the web…

Viene al vacío, por lo que está en perfecto estado de conservación hasta que lo abres. Es ligero, hidrata y no reseca ni causa molestia..

I’ve been using the this for about two weeks and have already noticed some improvement in my overall skin tone. My skin is combination, and the serum feels lightweight and easy to use. It has a dropper applicator and its a little runny, but it’s easy enough to apply. The scent isn’t too overpowering, which I like. I did experience a slight stinging sensation at first but no discomfort. Some of the product leaked onto the packaging, though wasn’t a significant amount.

I’m happy with the results so far. I might repurchase it, or try the higher percentage next time.

excelente produto! cumpre o papel perfeitamente, tem um valor bom, então é um ótimo custo benefício. recomendo muito

I really really really love these product so so much!!! Absolutely amazing! Obsessed!

сыворотка мне очень понравилась . куплю второй раз. уже положила в корзину) пахнет жареным

i loved it. it does the job well. u will spent it in 2 months if u use it every day

me ha ayudado mucho a iluminar la piel y es perfecta para complementar la rutina

Es fácil de usar, es acuosa y se disteubuye fácilmente en la piel, con 3.a 4 gotas es suficiente para el rostro... No irrita la piel, es bastante amigable con el cutis

I’ve been using the COSRX Vitamin C 13 Serum and I’ve really enjoyed adding it to my skincare routine. The serum has a lightweight texture that spreads easily and absorbs well without leaving my skin feeling heavy or sticky. I like how fresh and smooth my skin feels after applying it.

With consistent use, my skin looks more radiant and refreshed, and my overall complexion appears more even. It’s also easy to layer with the rest of my skincare products, which makes it convenient for everyday use. I appreciate that the formula feels gentle enough for my routine while still giving my skin that extra brightening boost.

Overall, I’m very happy with the COSRX Vitamin C 13 Serum. It’s a simple, lightweight product that leaves my skin feeling hydrated, smooth, and fresh. I would recommend it to anyone looking to add a vitamin C serum to their skincare routine.

Soy de piel mixta a grasa y como me daba miedo que me causara brotes por reacción, empecé haciendo una prueba de parche en una zona durante 5 días, y al no causarme reacción la pude empezar a usar en toda la cara con más seguridad.
He notado poco cambio, no tengo muchas manchas de sol, pero necesito luminosidad y en complemento con todos los productos que uso, me ha quedado bien. En próximos días actualizo mi reseña después de más días de uso.
Tiene solo un punto en contra, he leído que dura poco tiempo una vez que la abres. Si es así, no creo volver a comprarla.
Nota: conservarla en el refri una vez abierta.

I got it for my friend and she like it you all should get it , nice before sunscreen

la pedí para mi mamá, la piel se le ve más iluminada y pareja, empezó con la vitalmina 13, pero ahora le encargué la 23
