”19, M, Oily Skin. This product is incredible. I have a lot of post acne scarring, general redness, and uneven skin; introducing C20 into my routine changed my face in a matter of weeks. I cant even really tell what it did- what I know is that my skin’s redness is much more subtle and that many of my imperfections have been smoothed. I put this on after cleansing and toning, and while I don’t know any of the science behind it, I feel like I can say that it helps all the next products i use become more effective. Make sure you wait 20 minutes after using it for best results.”

”I started using this serum about a month ago and I have already seen big changes in my skin. I am in my mid-30s and suffer from Melasma and fine lines. After a month of use my skin texture is so much smoother and the Melasma that is above my upper lip has faded a lot.”

”I have combination/oily skin. After about using thus product for a month, I saw that my acne has improved, my pores were reduced a little in size, and my skin complexion became more even. I would buy this again and I definitely recommend this product!”

STEP 2: Initially, a slight tingling sensation may be experienced (a passing phenomenon).
STEP 3: Mix with several drops of toner to make your skin refreshed without feeling gooey.
STEP 4: After applying vitamin source C20, apply moisturizer to increase efficacy.

If you desire more hydration, use this product with the C20 Vitamin Sleep 9 to 5 Crema Sleeping Cream. After applying the C20 Vitamin serum, apply the sleeping cream over this layer. This combination will amplify the effects of Vitamin C.

Then you may use it without any problems.

Super effective!

Kinda hesitant at first to buy coz its quite pricey and my skin is so sensitive but gave it a try. It stings at first every time I apply it on my face but it's manageable. My hyperpigmentations did lighten, true to its claims. The only thing I don't like is its sticky, it feels like my face needs to wait several hours before it absorbs which is quite a hassle for some who doesn't have enough time or tinatamad at night. But overall 5 stars for its effectivity!

Gets the job done

This was the first serum I ever used and I must say I was pleased with the results. I usually apply this at night after cleansing and applying toner to my face. After using it for a few weeks, my acne marks were visibly reduced and I had less breakouts. After a month or two my skin became smoother and lighter (glowing!). I also loved its citrus scent! My only problem with this product was that it does oxidize and turned brownish in color even if I stored it inside the fridge completely away from sunlight. But still, this was very effective and a good buy for its price..

You Glow Girl!

This is the first and only Vitamin C Serum I have tried, but so far I am loving it! When I got into the Korean skincare craze, people were raving about Vitamin C serums, how it would make your skin glow and fade pimple marks on your face. I searched days for a serum that would do its magic and still be affordable (since I didn’t want to waste money on my first Vitamin C serum purchase). I came across the many good reviews of this product and that made me click the purchase button. And wow, did I not regret it! This has made my pimple marks fade over time (about 1 month use) that I cannot barely remember now where they used to be located on my face lol. And every time I use this overnight, my face just glows so beautifully the next day, I swear! The product stings upon application on the face (I make it stay on my face for not more than 15 minutes), but that just means it is working its magic! The (minimal) pain is so worth it! It is kinda sticky but smells so refreshing. I am on my 2nd bottle now, and definitely would repurchase soon! This product is indeed value-for-money, and really effective for me.

Better than Klairs?

So far i've been using it for a month but i like it more compare to the Dear Klairs Vitamin c Serum + this one is cheaper and is more easier to apply and i don't even get some stingy effect compared to dear klairs. i finished the whole bottle and i didn't event notice a significant difference though so far i notice a subtle scar fading on my pimple marks. :)

Goodbye pimple marks.. hello glowing skin!

Bought my first bottle and i was hooked.. my acne scar faded from continuous use, and my colleagues notice that my skin tone got even and a little bit brighter. It is easy to apply and dries within seconds. 1 bottle lasted 4 months. I do advice users to put the product in your refrigerator so the product won't oxidize and to have that cooling effect when you apply it on your skin
