I honestly can't say if this actually works bc I just opened the package. I can say that it came fairly quick and it was packed with other items, nothing was damaged.

Me gusta mucho. Pero es bueno usarlo 3 o 2 a la semana para que tu cararita se acostumbre si tu eres de cara grasosa como yo ..te lo recomiendo 👍

Great new addition to my skin care routine! They help with dark circles, wrinkles and puffiness.

Love! This oil feels so good I'm your skin and absorbs quickly! If you use a skin oil this is highly recommended 👌

Just started using this but the first time in 1.5 hour I saw some improvement in my skin
Photo on left is right when I first put it on and photo on right was an hour and half later I will post more pictures in about a week

I’ve only been using for almost two months consistently honestly I can’t say if it’s working just yet but my skin takes it in quite well

I really like this serum, I been using for 2 weeks and I already feel the difference in my face
Even though it is oily, the skin absorbs it very well and quickly to continue with my skin routine
Definitely I’ll will buy it again because after try a lot of different brands this product is fantastic

This was a re-purchase. On my second bottle. Use this every other day and it really makes a difference! I have re-purchased COSRX products. I love this line! One of the best retinols I’ve used.

I love this product. My face looked better after one day. I will buy this again. I have been very self conscious about my face and this product makes me face feel and look more clear…

I'm pleasantly surprised that I had no negative reactions to this product. Being cautious I originally tried the sandwhich method. After no tingling or burning I used it directly after wash and toner and my skin was fine. No redness, bumps or breakouts. Would recommend
Skin type: very sensitive
