This came with the dropper broken. I was very excited to try this. I now have to return & re-order since it’s impossible to talk to someone to remedy the situation

Received product in good condition. Loved the price snf the shipping. It came quicker than I thought. Keeping it in the box it came with because I don't have a mini fridge for skincare. Product itself is not oily and absorbs easily into the skin.

For the October Skincare lineup, I’ll be adding the @COSRX Official  Vitamin C 13 Serum to my nightly routine to help fade my hyperpigmentation. I’ll be trying for a month and if i see improvements keep it in the routine. If you’ve tried let me know your thoughts  #skincareroutine #skincare #cosrx #cosrxbestseller #koreanskincare #koreanskincareproducts #koreanskincareroutine

Yeah it’s an ad for a vitamin C, but I was interested in trying out their vitamin C because it was pretty low cost, and I liked the CosRx snail mucin. Overall it’s a decent cheap option. We can’t know exactly if it works like we know the other one works (CE F) but it has decent potential. Lmk y’all’s thoughts.
