This serum was one of the first Korean skincare products I tired, and it will forever be one of my favorite products. I had been living with postinflammatory hyperpigmentation for years, I could not even remember what my skin looked like underneath all those dark spots. Enter C20. The initial tingling sensation after the first application scared me, but it never happened again. Once the initial scare wore off, I discovered a new skin within a cou...

This is a huge favourite in the AB community and I can totally see why. Initially when I used it, it tingled a little but nothing uncomfortable. I have been holding off writing a review until I used it for about 8 weeks and I can confidently say now that I love it and the brightening effect is totally visible. Yes its a sticky product and I would not dare use it during the day. Also sunscreen is a must if you are using any sort of acid! Yes it ox...

I find this serum to be very sticky but i can live with that becuse I've seen visible progress in my scars fading and reduction in hyper pigmentation within two weeks of use  unlike the c21.5 which didn't do any thing for my skin. It doesn't oxidize as quickly as the c21.5, it's cheaper and only tingles when there's a problem with my skin e.g over exfoliation. I use it at after cleasnsing with a low ph cleanser before my BHA. I can't attest ...

This serum is a bit thicker and stickier than the other serums, and takes a longer time to be absorbed, but still, my skin absolutely loved it. my skin becomes really crazy during spring and gets easily irritated, but this serum helped equilibrating it, calmed it down and sped up my pimples' healing process. for a more in depth review, check my blog post here: http://www.mykoreaobsession.com/2015/06/ost-original-pure-vitamin-c20-serum.html ...

Mentally, I like it, but physically, it says it ain't so. In the first weeks, I noticed it did face my previous scars, but it also purged me, rendering the erasure of other scars moot. After I was done with the bottle.. I was left with a worse face.

I thoroughly enjoyed this product.  I noticed my skin was brighter a couple of days after using this. I've incorporated this into my night routine.  Not only is my skin brighter but it also has a nice glow as well.  The scent isn't too strong or anything. But it does dry very sticky, which I'm not a fan of. Once I continue with the rest of my skincare, the stickiness disappears.  Overall, I'm in love with this product. My ...
