”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!”

I ordered because of the reviews! And It’s my first time to use a vit c serum. Sa unang application nagkapimple ako kinabukasan and parang gumaspang yung face ko :( pero ngayon lumiit na yung pimple and tinuluy-tuloy ko pa rin yung product. Siguro nabigla ang face ko sa product kasi di naman talaga ako nag-aapply ng kung anu-anong keme-keme sa face ko. As of now, hindi naman na ako tinitigyawat kaya tuluy-tuloy ko ng ginamit. Naggoglow na yung face ko pansin ng tricycle driver samin hahaha! Pag maubos yung cpg oil ko itry ko rin to sa ua ko hihi. Btw, I’m using it for almost 3 weeks!26 days ago
Smells sweet 😊 i put in the fridge to keep it cool and so when i apply it in my face, it’s super awesome..cool and refreshing. I let it dry for about ten minutes before applying my moisturizer. It keeps my face soft and supple in the morning. After a week, my face brightened 😊about 2 months ago
Been using this for months! And I'm so happy with its results. It has lessened oiliness on my face and lightened my pih scars. After using this product my skin feels supple and glowing. After seeing results, I even recommended this to friends. Do try this product. And don't forget to store it in your fridge as it is sensitive to temperature changes. Will forever repurchase and recommend.about 2 months ago
Started to incorporate Vitamin C into my skincare regimen with TIAM My Signature C Source and it has been the best!!! It does not dry up the skin and it evens out my skin tone. You'll see results within two weeks! It gives you that refreshing glow! I store mine in the fridge, as the 20% Vitamin C in the amber bottle tends to react quickly once exposed to light.about 2 months ago
I've been using it for about 3 weeks now and I can tell that my skin's redness is much more subtle and my imperfections have reduced. You will feel stings in your face cause that's how it works. Just wait for about 20-30 minutes to allow your skin to absorb the serum before you apply the next product of your night routine. Will definitely recommend!2 months ago
I'm using this as an active. I apply this first before the COSRX BHA and AHA with 20 minute intervals in between all of them. Before using the BHA and AHA, this serum has already lightened my hyper pigmentation and it has also brightened my face. With the BHA and AHA, I've noticed that there's lesser pimples now. I suffer from adult acne but I think continuing to use this product will stop that. Do buy this product!3 months ago
