Vitamin C is a very powerful antioxidant and supposedly also helps your cells to create more collagen, etc. That’s why it’s frequently a star ingredient in a lot of skincare.
The cheapest and most widely available Vit C for us in Asia is likely to be the OST C20 Vitamin C Serum [affiliate]. It’s available for a super cheap $15.57 plus shipping from Roseroseshop.
I bought it and used it mainly because of the scarring on my chin from the hormonal acne. If you look on the internet, some common criticisms are that it contains Niacinamide, which is what you DON’T want to mix with Vit C, and that Ascorbic Acid is not the best form of Vit C to use.

Overall, the texture is a viscous liquid. It smells to me like hotdog brine – slightly salty. It tastes slightly sour and salty too if you get it on your lips. I don’t mind it, I don’t find it weird or offputting. It dries slightly sticky, but it doesn’t matter to me because I put other stuff over it anyway. I had a tingling sensation the first few times I used it, but it’s non irritating and it won’t make you red. It does sting a little bit if you’re using it on pimples.
I first got it on 9/10/16, so it’s been about 3 months. I still have about 1/4 of the bottle left, and that’s only because I really doused my face in Vit C almost everyday and I even used it on my arms for awhile. I keep it in the fridge, and it hasn’t oxidized, so I’m pretty happy.
I used to use it right after cleansing in the evenings, but Vit C + AHA + BHA was a bit too much for my skin, so right now I use it in the mornings and use my AHA + BHA in the evenings. I wash my face, sometimes with a bit of cleanser, sometimes only with water, pat it dry and then apply it. I usually wait for a few minutes and get dressed before putting on the other stuff.
My chin scarring is still present because I keep picking at my skin (I’m working on it I swear) so there’s not much photographic evidence there, but here’s evidence of its effects of the spot on my cheek.
Some background: I fell down flat on my face around 10 years old, which resulted in a huge scab on my cheek. I never really actually noticed this scar until I got older. I don’t really mind it, since it’s not very obvious or terrible. It’s just a small patch of darker coloured skin on my left cheekbone.
Defying logic, I somehow placed the before pic on the right, and the after pic on the left. The difference isn’t crazy dramatic, but it’s not as dark or as stark now, and the edges have softened up considerably. Note that the picture on the left is a super close up (which means it should be all the more obvious) and the one on the right is zoomed out.
Overall, this Vit C serum is a great beginner’s serum. It’s cheap, reasonably effective and easy to get from Qoo10. However, there are definitely better formulations out there. I’m going to be trying this one next, which is way more hardcore. However, this is dependable (and so budget friendly) that if future ones I try don’t work, I would definitely return to it.
