So many pros and cons

I've been using this for a little over a month now and there are so many pros and cons to this product. PROS: Effective in lightening acne scars and brightening acne scars and overall complexion. I noticed a huge difference with my skin and I was really pleased with the results. HOWEVER, I notice that the first couple of times I've used this, my skin stung a little. Because of the red color, it's really hard to tell if it's gone off already. Every time I apply this to my skin, it becomes tinged yellow and leaves it a little tacky. I have to let this absorb into my skin for about 5-10 minutes otherwise it pills. This also transfers onto my pillowcases which makes it a huge hassle to wash. I honestly don’t think I’m going to repurchase when I run out.

Wasted my money

So i read good reviews about this product thats why i did not hesitate to give it a try. I ordered it at night and it arrived early the morning after. I wAs really excited to try it but to my surprise, as soon as i opened the box, it was leaking :( i didn’t throw it yet because i was still hoping it’s not yet oxidised so i still followed the instruction, i put it in the fridge for 48 hrs. When i opened the bottle for the first time, it’s not red color anymore. :( it’s orange bubbly and malapot. I wasted my money. I haven’t got a chance to try it. Beauty manila if you’re reading this please do something :(

Much better than the original

I bought this with a bunch of the ordinary and cosrx skincare. It’s the best one of the bunch. Ive always used the signature C one but this one is noticeably stronger. It feels like an astringent on my face and the smell is more pungent. But it is great. Ive been using it again and again. Ive had this in my skincare routine for about 5 mos now and I dont break out anymore, not even on my period. I actually started using this during a pretty rough breakout (I was desperate). Within 2 days all my cystic acne were flat. It’s some kind of magic on my skin. I have to say, this works much quicker than the signature C. But I think the color prevents you from being able to fully tell if the product has gone bad.

Not for me

I've been using this for quite a while now. I like it because it helps lighten my dark spots and makes my pimples shrink. But after a week or so I started to develop comedones/blackheads all over my face. I quickly stopped using this. After a few months when the comedone/blackhead disappeard I used it another chance (sayang 900 ko eh) but only on my troubled spots. And true enough I noticed new comedones on the area where I applied the serum :( Sadly I won't buy this product anymore.

why does it sound like i opened up a can of soda?

When I first opened the bottle so I can put the dropper in, there’s loud hissing sound like you opened up a can of soda which is weird for a skincare product. And it bubbles too. Maybe its because of the high concentration of vitamin C? but when you apply it onto your skin, it absorbs very quickly and it works well with my other skincare rituals as well. My post acne scar lightened up a bit, but on the other hand, I experienced some teeny tiny bumps which is tolerable. But one word of advice, put it in a refrigerator and not in the freezer, because if you do..the product will explode, which is a stupidity on my part.

Went bad really...really quickly

As one who suffered from acne breakouts for most of my recent years, one persisting problem of mine is PIH marks. I tried this out after being convinced by online reviews, and by the end of a month I am very torn. On one hand, it really is a STRONG serum. And I thought I was used to acids at this stage, this made me flush quite bad. It goes away within an hour and faster when you layer moisturizers on top of it right away (but that is counterintuitive). Other than that, as well as the usual initial tingling, I never experienced any adverse reactions. At first the high alcohol content was concerning, but after 3 or so uses I found that I didn't get dry. After 2 weeks of using it every other night, its effects are pretty noticeable. Acne scars are lighter, my face is smoother and much brighter. It was astounding! EXCEPT...there is one kinda major problem. Not sure if its me or that I got a bad batch, but my serum turned from red to verrryyy orange in just 1 month even when I stored it in a refrigerator all that time. Because its pretty expensive I'm not keen on repurchasing in fear of being through with in another month.
