”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 1: Apply after cleansing and toning. Use 2~3 drops and smooth in gently all over face (especially over the aged areas such as pigmented or wrinkled lesions).
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.

Because of the hot weather, some vitamin serum can be leaked. But this is a natural phenomenon that can only happen to pure vitamins. When this happens, wipe leaked liquid, and keep it in fridge. Then you may use it without any problems.

Better than expected!

I used to apply the vitamin c from The Ordinary for my nighttime routine but I saw this vitamin c from TIAM on a much discounted price (& since the one I used before was about to run out) I bought 2 of these in a heartbeat. Been using this for a week now and it's better than what I expect. It doesn't leave brown stains on my clothes and pillow cases unlike the vitamin c from The Ordinary. This one from TIAM only dries and leaves flakes on my face in the morning (no stains! less worries! haha) The brightening is the same. But on my current product I'm more cautious on handling it since many reviews said that it oxidizes easily, unlike the one from Deciem where I can store it in room temperature. But all in all, I'm happy and contented with TIAM. Got 2 bottles in a price of 1, and it's much fun applying a face product with a dropper. 😅😄

Does its job

When I had a trip to the beach and got my skin badly burnt, I used this along with Farmstay grapeseed serum. Did its job in skin repair and brightening. However it oxidized rapidly even when stored in a ref. Also had a stinging sensation every time I apply it. So I did not finish the bottle at all. Worth the try.

Holy grail

I love, love, love this product! Vitamin C worked wonders for my skin. It made my face smoother, it lightened my acne marks, and it gave my cheeks a slight pink blush. One bottle lasted for about 3 months, so it’s very sulit. It did not sting the first time I applied it on my face; it actually felt very relaxing because I stored the bottle in the fridge so the liquid felt very cool. Will definitely buy this again!

Not for me

Doesnt work for me. First serum ive tried pero parang hindi sya effective sakin. Instantly got a big acne just after application of this. ganun kasensitive yung skin ko. Tried giving it a second chance and all but doesnt really works for me. Maybe nahype lang ako dahil daming good reviews but i think it depends on the skin type.

Holy Grail and Gateway

I've always heard great things about this so when I first decided to purchase it, my expectations were really high... And I wasn't let down at all! A week of usage has greatly reduced my dark spots and my acne has started to calm down too. This has always been my Holy Grail but also my gateway product into loving more and more Vitamin C skincare products! Lol

Likey yay

Great and effective product for its price point. Been using it for only a month and results are already visible. I have sensitive skin but 20% Vit C surprisingly did not cause any redness or peeling or whatever. I would give it 5 stars if it didn't break me out the first week.
