You may know that one of my favourite products from Wishtrend is the OST Original Pure vi-ta-min C20 Serum. I reviewed it previously, but I didn’t have any before & after pictures. Nevertheless, I was really impressed how the serum changed my skin and made it so much better in various aspects. When I saw that there was a new version of this I was most excited lớn try this new OST C20 Pure vi-ta-min C21.5 Advanced Serum. And, as you might guess I had high expectations for this serum. Could it hold up khổng lồ them?

As with the previous serum the cardboard box comes with a lot of description in Korean và in English. It is very detailled in how to use it & what precautions lớn take. The new serum has even more details in English, than the previous packaging. The ingredient list of the new formula is very short. You can look them up on COSDNA and you’ll discover that the ingredients are safe to lớn use và that there is no artificial ingredient either. The ingredients of the old serum were safe to use, too, but the menu of substances is much longer as you can look up >>here

The dropper makes it very easy to lớn take out the watery & runny product. The OST C20 Pure vitamin C21.5 Advanced Serum has a clear color, which is also a sign that the vitamin C serum is fresh. If it turns yellow the vitamin in the bottle has started khổng lồ oxidize. The scent of the product reminds me a bit of oranges, but with a different scent combined, which I cannot figure out. The scent is not strong & doesn’t linger on the skin, so it doesn’t matter anyways.

Did the new OST C20 Pure vitamin C21.5 Advanced Serum fulfill my expectations? I’m not sure. Somehow I have the feeling that the old formula was more effective. I remember with the old formula, that I felt a stinging experience the first times I used it. I didn’t have any feeling like this for the new formula. Maybe, this new formula is better suited lớn sensitive skintypes than the old one. I could observe a decreased redness in my face, but I cannot assure that it is only due to lớn the new vitamin C serum, but it will be a combination of my skincare routine as a whole. Maybe if I repurchased this serum I would go for the old version, just because I had the feeling it worked better for me (and lớn confirm my observation). I can recommend you lớn try this new formula of the C20 if you were unhappy with the previous ingredients. This formula is almost completely different and doesn’t contains any parabens or other artificial ingredients. It doesn’t contain alcohol either. The old formula does have some cons, like the extreme stickiness & the ingredients, but I would not claim that the new formula shows better results, even with a higher concentration of vi-ta-min C. Both serum, the old and the new version can be purchased at Wishtrend. The old OST Original Pure vi-ta-min C20 comes with không tính phí shipping & retails for 14.99 US$ at the moment, which is really affordable for a vi-ta-min C serum. The new OST C20 Pure vitamin C21.5 Advanced Serum retails for 24.99 US$. Both bottles contain 30 ml. I made a post about the promotions from Wishtrend for March >>here
