I think the mistake many people make with this serum is that they use too much of it. For years, I was using a higher percentage from GG and Missha. My skin barrier was destroyed. I switched to this serum, which has a very good percentage of pure vitamin C. My skin calmed down and is very bright. Guaranteed.

Wonderful, you feel that tingling on the skin which makes you realize it's working! My skin changed within a month, I don't know if it's because of this of course, but it glows! I follow all the steps of the Korean skin care routine

The scent is nice, the result is mediocre compared to the other products of the company. The packaging is terrible, the product wouldn't come out at all.

very good product, leaves no greasiness, is absorbed immediately, leaving the skin soft and radiant
as soon as I opened it I put it in the fridge with its box and nothing has happened to it at all in the 2.5 months since I bought it
I recommend it and I will buy a second one again

It kept leaving orange stains all over my face! Also, it didn't work at all! I didn't notice any difference!

Very good product with excellent absorbency and pleasant scent. I constantly read negative reviews that it spoils in a short period and gets thrown away. If you close it well and make sure it is in a cupboard with a normal temperature, nothing happens to it! I will definitely buy it again

unfortunately it oxidizes very quickly even though I kept it in a cool place and so half the product was thrown away

Placing it in the refrigerator extends it by a few days...... it is preferable for the packages to be 15-20 ml

This is one of the nicest vitamin C serums available. It is guaranteed for use on sensitive skin, has a wonderful orange scent that you won't find anywhere else, and deeply moisturizes the skin. You won't easily find this in a vitamin C serum either!! The only disappointing thing is its price. It is very expensive and inaccessible, leading me to look for other cheaper ones that unfortunately do not have a nice scent and may not offer hydration either... I wish there were at least good offers like with sunscreens. Not even that exists... And we are very disappointed because we would really like these products to be accessible to most people.

age 32: I have been wearing it for over a month now and the truth is that I haven't seen any difference in my skin. However, it temporarily leaves a nice feeling, hydration, and glow. The applicator doesn't work, resulting in having to try many times for the product to come out. It generally has a nice feel, indifferent scent. I have never used vitamin C before, but I can't say that I had any wow feeling wearing it to justify its price. Oh, I should mention that the products applied on top layer very nicely

It absorbs and then you have the feeling of a film that rubs off. Awful feeling, no improvement.
Terrible.
I wouldn't buy it again

It would be good if the packaging showed that the gift they are giving is a microscopic sample and not misleading by showing the actual size of the product which they simply DO NOT offer.
