3/5 I really don't know what I think about this product. I have been using it for a while now and I don't feel like I've seen any difference in the brightness of my skin nor my acne scars. The serum stings and Itches SO much if you don't mix it in with another product so I would highly recommend doing that. Overall it's an okay product, I did see a difference in my skin texture and plumpiness but that wasn't the reason I bought the serum. I would personally recommend getting the sheet masks instead as I absolutely loved those.

5/5 I have oily, sensitive and acne prone skin. I had this bottle for few months and I didn't notice a huge difference which is probably because I don't use it as often. The last month I've started using it every single night and when I wake up in the morning I definitely noticed my acne scars are slowly fading (I have really bad scars) and my skin is a lot brighter. Instead of putting 3 drops onto my face and tap it in, I squeeze out all the liquid in the dropper onto my palm and quickly rub it together with both hand and gentle pat it all around my face (the key is to do it quickly otherwise the serum will absorb it all on your hand), focusing on my cheeks as that's where majority of my scars are. Also every other day I would use the Vitamin C2.15 mask after I put the serum on. Perhaps I'm used to it, my skin does not feel heated or tingly after applying the serum. Just avoid the eye area ;) Also it does feel sticky after you tap/pat the serum onto your skin but it goes away once you put your cream on. I also use the Cosrx snail essence and cream after the serum. My skin feel so repaired in the morning! I've already repurchased!

5/5 This new version is not that sticky, than the old one, but it's really a miracle product! It hydrates and calms my skin and literally prevents every single pimple to form. Maybe I like the old version a bit better, because I feel like that hydrates a bit more effectively, but this one is less sticky, so... :) I don't know which one to re-order.

5/5 I've used the freshly juiced vitamin drop serum before this product and I think that this one works better.
But if your skin is really really sensitive I would use the vitamin drop serum (be patient to see some result). I use it at night time and I can see how my acne scars are fading =)
really love it

5/5 I have never used and most probably will never ever use any other vitamin serum other than this. I have used more than 6 bottles of it and I never get tired of it because my skin loves it too... Highly recommended for people with dry to combination skin like mine.
