O.S.T . Original Pure Vitamin C20 Serum


Skincare is my top priority.  Good skin = Less Makeup = Less Expenses *laughs*  I was organizing my skincare stuff when I saw this in our fridge and just remembered that I haven’t posted my review about this amazing serum which everyone goes gaga for its effect on the skin.  Another thing that took me long for this review to be published was that my first attempt on this serum wasn’t really that successful.  I’ll let you know as we go on.

The packaging is nice, looks so elegant and simple with its orange glossy theme.


The back label is purely Korean so I can’t understand any single word it says. *laughs*


Manufacturing and expiry date are both printed at the bottom of the box.


What I really like is that the bottle is sealed.  It comes with a normal bottle cap that you can replace with the dropper cap once you’re ready to use it.  It ensures 100% freshness of the product when you get your hands on it.  The details on the bottle are exactly the same with the box.


It comes with this glass dropper that has enough hole at the tip so you can control how much product you want to use.  2 – 3 drops are enough for the whole face and neck.  You may opt to add more if you want.

Below is a sample of how much you get for a single drop.


How it looks like when spread on the skin.  It looks more moisturized without making it look greasy.

First week of use

I was having these days as signs that my monthly period was coming.  First two days were good.  But on the third day, I began to breakout like crazy  even my neck had some pimples which was my first time to ever have experienced that kind of extreme breakouts.  That being said, I had to stop using the serum and see if it’s the culprit for my misbehaving skin.  I also thought maybe it’s because my period was coming so I had to wait till I was free from red flag days before I was able to use this serum again.

Second chance, 2 weeks more

I began to use this again.  My breakouts have subsided so I will definitely see if my skin will get worse for the second time.  I just used this every night after my moisturizer.  Leave it on my skin until the next morning.  I’m happy that the result was much better.  I wasn’t able to document the before and after as I also used other products so I think all of them contributed to the betterment of the condition of my skin *smiles*




?  Very hygienic to use and the packaging is good too

?  Not greasy, AT ALL!

?  Unlike other serums, this one is not thick in consistency.  It’s more on watery and very easy to spread and massage all over the face.

?  Easily absorbed by the skin.  It feels so light like you didn’t put anything at all.

?  Has citrus smell like that of pure vitamin C that we intake daily.

?  Tightens the skin and makes it more moisturized.  I didn’t see too much whitening effect as I think my skin has reached its whitest state.



?  Price.  It’s 24.99 USD (approx. P1,050.oo+)

?  Not available locally, only via online or resellers

?  Those with sensitive skin should do patch test first for 48 hours at least



?  Put in a cool and dry place.  What I do is put it inside our refrigerator just below the eggs’ tray.

?  I use this at night only

?  If you’re using moisturizer or other products prior to this, please let those set on your skin first.  Wait at least 15 minutes then apply the serum.  It actually depends on your preference but that’s what I do.

?  Good for any skin type.  For severe sensitive skin, consult your physician first.



Maybe, but not now.  I still have a lot of skincare products in line for me to try.  I can go back to this though but not that soon.




It’s good even though my first try wasn’t successful.  At least, it goes well on my second try.  I love the fact that it’s safe to use for all skin types because I really hate serums that are really thick and make you feel like you put cooking oil on your face.  I stopped using this though as I’m road testing another skincare brand and I alternate my skincare every month or two months.

  1. Im glade it worked on the second try! ^^
    Don’t forget to check my giveaway!


  2. There are products that deserve second chances. Vitamin C is good for the skin and we can always blame our period for the pimples. hahaha I miss you <3

  3. ahhh… That breakout gave me a scare. O.O *shakes head* Good to know you’re alright now. 🙂

    1. hahaha me too I was like “OMG what happened to my skin” but yes, I think it’s because of the PMS thing 😀

  4. You didn’t give up and gave it another shot. Great that it worked on you the second time around. Although it sucks that it’s not available locally. If it reaches the Philippines, it’ll be way expensive na.

    1. Yes, since I’ve seen a lot of good results using this product. I really tried it the second time hoping that I’ll work and it did! 😀 Yes, the price is pretty expensive.

  5. I bought this recently too! Waiting for it to be shipped over. Hope I don’t breakout like what the honey did to me. Ugh… Definitely doing a patch test.

    1. That’s nice. I hope it won’t. Do patch test first 🙂 Update me with your review soon 🙂

  6. I would agree that it’s a bit expensive. hehe. But with the review you did, i think it will be worth the purchase. 🙂

    I totally agree with you on that one – skin care was also my top priority back in the day especially when I was an active beauty blogger – this is also why most of my blog entries were all about skin care – maintenance and etc.

    Not because of the expenses, though, haha!
    But because.. I personally think that natural beauty is what will stand out at the end of the day. 😉

    I love serums! I’m using a different one though not really hard to use.. hehehe! (Ysabel Daughter’s Revitalising Facial Serum) but then regardless of the brand – serum is a serum and its always good + the benefits it has within it!

    1. Thanks Aisha. Totally agree with you. I think I’ve heard that brand before not just sure where. Healthy Options?

  8. looks like a good product! I love the packaging too simple lang pero I think it’s a bit pricey pero since you’ll bee using 2-3 drops lang naman i think this will last a long time. 🙂

    1. Same here. I’m a fan of whitening products lol 😀 Yes it is. It also improves the skin 🙂

  9. I also tried this one. Sad thing though is that my sister accidentally dropped it. Ayun, wala na. Sayang kasi effective talaga sya. Great review, as always, Gen! 🙂

  10. Gosshh!!! Did I read about OST Vit C Serum??? I LOVE it girl <3 Great review and I so agree with your review here 😀 Great share 😉 😀 This is my abs love for 2013 for sure xxxx

    I’m definitely a skincare gal, if I can get away with having a really good skin, I probably will not touch makeup stuff anymore hehe ok maybe a BB cream and then lip balm.

    I love this serum, but I think I wasn’t able to get the best out of it due to not enough info – this serum was best to be stored in the fridge, umm didn’t know this until like weeks later LOL – and I felt that it must have oxidized and lost it’s mojo BUT my skin saw a big difference and I will definitely repurchase this again once my other ones run out. I normally put this after toning my skin so it really sinks it and do its work – but I guess moisturiser first works, too x


    1. Hi Dona! Same here right. If only I have clear smooth skin 😀 Oh, I was advised by a friend to put it in the fridge so the moment it arrived, I store it there 😀 I’ll try that too, use it after toner. I’ll let you know if it works just the same 🙂

    I think the price is just right considering that the quality of the product is superb. =)

  13. hard if the skin reacted then you are using a number of products. kaya im so hesitant talaga to use other brands kasi my skin gets “tampo” when i switch to another brand. haha just sharing :p

  14. Am I the only girl who doesn’t care about my skin? lol that’s why I have the ugliest skin on earth. LOL I’m scared to try some skincare, arte kasi ng skin ko. 🙁 I got more scared when something happened on your first try but good thing it worked on your second. 🙂

    1. Hi abhie! Ah baka you have super sensitive skin lang 🙂 You can ask your derma what’s the best skincare to use kasi mahirap for you magtry baka mairritate skin mo 🙂

  15. Good skin = Less Makeup = Less Expenses — this is true. Taking good care of our skin is really important 🙂 Great product, sayang at hindi siya available locally. 🙁

  16. Hi, Did you get this at wishtrend? How did it get delivered? I don’t want it to go through post office because customs in the Philippines sucks.

    1. Hi Dear! Yes, I got this from Wishtrend. They delivered via post office 🙂 I only paid 50 pesos for the tax I guess 🙂
