You may know that one of my favourite products from Wishtrend is the OST Original Pure Vitamin C20 Serum. I reviewed it previously, but I didn’t have any before and 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 to try this new OST C20 Pure Vitamin C21.5 Advanced Serum. And, as you might guess I had high expectations for this serum. Could it hold up to them?
The brand OST or C20 is best known for the popular OST Original Pure Vitamin C20 Serum in it’s signature orange packaging and the brown bottle. This serum is highly effective in terms of using the peeling ability of ascorbic acid in order to improve the skin condition. Despite being effective, it had some minor cons, for example it was very sticky, it was too aggresive for people with sensitive skin and it contained some artificial ingredients. The new OST C20 Pure Vitamin C21.5 Advanced Serum has a completelly different ingredient list and as the name says, the amount of vitamin C serum has been increased, too. The original serum contained 20 % of Vitamin C whereas in the new formula you will have 21.5 %. Vitamin C is an antioxidant and thus can prevent our skin from aging too early. The content of Vitamin C in both serums compared to other vitamin C containing products is rather high. It contains 20 % [21.5 %] Vitamin C. You have to know that a high concentration of Vitamin C doesn’t mean automatically that it is more effective concerning anti-aging. Normally, a high concentration of Vitamin C aims at a visible effect, because it tends to operate as a peeling by loosening dead and old cells. This is not a bad effect and stimulates the skin to regenerate itself, but keep in mind that it won’t affect the inner cell layers of your skin which have to be aimed if you really want an anti-aging effect.
As with the previous serum the cardboard box comes with a lot of description in Korean and in English. It is very detailled in how to use it and what precautions to 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 use and that there is no artificial ingredient either. The ingredients of the old serum were safe to use, too, but the list of substances is much longer as you can look up >>herehere
