This is the best serum I've tried! Makes my face so smooth....good for acne too! 

If applied on damaged skin might sting, Its brilliant for night care. fades away scars, cleared out skin. I would like to try their cream that compliments this treatment for sure. even after a few months of non usage , skin became brighter and tighter. It did go bad at one point at the last drop, Might be good to keep in a dark place? fridge maybe?

Semoga kulit bisa kinclong pakai ini

It does smell really nice and it brightens up my face beautifully. I also think that my acne scars got a lot lighter since I use this serum! As some mentioned before, this gets sticky after you apply it, but to me this is not a problem at all 

- this definitely has helped fade my scars; i got results within...3 days? 4? 

- the scent is citrus-y but when it oxides it smells kinda bad lol

- it leaves a tacky feeling on the skin (moisturizer over it should help a bit)

- burns a bit at first use (normal for vitamin c serums i'm sure) but not as much later on 

- gel-like consistency (a little more watery than a gel tho) makes application easier

- absorbs in easily

 

This is a great serum- for reference I have oily skin. It leaves my skin feeling soft and evens out my skin texture. Would recommend. 

I'm still afraid to try the serum. 

Something clearly went wrong during delivery or before: when I opened the package, there was some leakage.

Did anyone else had similar experience with this product? 

It also smells a bit weird - like iron and alcohol mixed together with other chemicals. 

 

Didn't really changed my acbe skin

I will not repurchase. The product oxidized wayyy to quickly. I could not use a majority of it. I would recommend the klairs vitamin c serum more.

It is a good serum but I just use in the night because is a little heavy for the day (and if course for the vitamin C you need to take care of the sun exposure)

It's okay, I don't find myself reaching for it very often because of the consistency. It's very sticky and dries fast so it feels weird when doing my whole skincare routine

Helps improve scars and any pigmentation, highly recommend

When I read other reviews I was like: I need to try this since I have a lot of redness. It did help a bit but I haven't seen any amazing results. I also noticed that it dries out my skin slightly and stings if you have any sensitive areas.. but I guess that makes since it is pure vitamin c. So just keep that in mind if you have really sensitive skin.

You know the struggle is real when a stubborn acne leaves a scar and hyperpigmentation thats near to impossible to fade away using all the products that you could get hands on. Well, yeah that struggle happened to me for like 6 years now. not until I found this product from a youtuber and decided to give it a try. And from the moment I start seeing results in just a short period of time, I can also see my social life having the same result. Both of them are getting sooo much better and sooo much brighter! PLUS this serum just makes my "damaged" face looking smooth and healthier over time. definitely recommend to anybody who has lots of acne scars/hyperpigmentation all over the face.

this serum is definitely worth the hype.

This serum really great, I can see a result when i used it first time, it make my skin really amazing, and i would like to repurchase again.

this really helps lighten my pimple marks and heals my pimple really fast whenever I'm having a breakout. I will definitely repurchase this and will be sending one to my cousin too. 

Been using this almost nightly for close to a month, in conjunction with the OST Vitamin Sleep 9 to 5 cream, and I have noticed a gradual fading of fresh pimple scars.  Cannot yet see other claims of blackhead removal, whitening etc... Although Vit C as an antioxidant should fight the effects of aging over long periods of use.  I find the serum quite sticky and stinging on the face, so I'm not sure if I will keep using it as I do not have much pimple/acne problems to begin with. 

Maybe this serum dont suit on me. Everytime i used at night routine, i got white and small bump on cheek. It also made my skin looks darker. I only use 1-2 week aprox.

very good, recommended!

Skin looks better and better after used

Is absorbed into the skin very fast and leaves it feeling very soft and immediately smoother.

It abit sticky but works on me. But it also makes me feel itchy at the same time.

Honestly i feel a really big difference whenever i'm running out of this serum. This makes my skin so much better. Even for my "wrinkles" (i'm on my 20's so this is small wrinkles tho) after some use it really dissapear. But when i'm running out of this product then it appears again. It makes your face brighter... Anyway yeah, i recommand it.  

It was oxadised already when i received it... And it was leaking out of the bottle... I couldn't the maximum benefit from it since it was already oxadised... This product so sticky... I didn't notice any change on my skin maybe because i didn't recieve it in a good condition...

Smells literally like orange you guys. not only they brighten up my face throughout the day, but also the dark spots from acne scars .

Love that it arrives sealed separately from the dropper. Has helped with hyper pigmentation. 

Good serum. My skin is a little bit brighter. Maybe using in long time will have better effect. 

This product has been talked about a lot in the beauty community and I see why. It is an excellent vitamin C serum. My advice is to use this right away. I bought a back up of this and left it stored for a while, when I opened it sadly it has gone bad so you have to be careful and follow the storage instructions.

I've been using this for more than a month now, and I did notice a bit of lightening. Maybe if I will continue it, (or if I try the C.21 one?) I'd see more visible results. I was afraid it'd be harsh on my skin, but other than some heat, I didn't feel any stinging at all.
