O.S.T Original Pure Vitamin C20 Serum Review

"Disclosure: This product was sent to me for review purposes in exchange for my honest opinion after trying it out. " Complete disclosure here

Hello, lovelies~ Have you incorporated antioxidants in your skincare routine? Antioxidants are not just useful when consumed in tablet form, but also have its benefits if applied topically on the skin. I've used antioxidants before on my face, but lately I didn't. Hahaha..

A few weeks ago, I received a product from WishTrend to review and share my experience with you all. It is none other than Vitamin C serum from O.S.T. I've used it for two weeks every day and night to see how my skin would react to it.

A dropper packaging

It comes in a glossy red box that has most of the description in Korean. The box is quite sturdy as it has a thick carton lining on the inside.

Once I take it out of the box, the product is packaged in a dropper-type bottle with a dark-stained glass bottle. I wonder if the Vitamin C would just evaporate and vanish when exposed to air every time I use it. 

I think it would be better if the Vitamin C is packaged in an airless pump bottle to minimize air exposure, so that I'm sure that the Vitamin C is still preserved. ^_^

Its contents

It has a high content of Vitamin C or Ascorbic Acid as the second ingredient in the list. The tea extract 

The third ingredient in the serum is ethanol and I do have sensitivity towards that substance, so I had acne within the first week. However, if you have no sensitivity whatsoever against alcohol, go ahead. ^_^

The consistency

The OST Vitamin C has watery appearance, but a gel-like feel on the skin. It spreads easily on the skin and sinks in rapidly within a minute. It has an orange scent that disappears after a few minutes of application. 

How to use it

I usually use it alone without mixing it with any of my other beauty product, but it can also be mixed with toners. In the picture below, I tried mixing it with a body butter and it works wonderfully as well.

The effects

Since I've only used it for two weeks, I haven't noticed any improvements in skin tightening. However, I'm happy to report that it does brighten my skin and Mr. G's, LOL. I gave him some of the serum and his face looks brighter each day. Apart from brightening, my skin feels soft and smooth without having a greasy or sticky finish.


Priced at USD $24.99 at, it is one of the affordable antioxidants out there. I've used one before and that one cost me around Rp 500,000. If you are someone who wants a brighter, softer, smoother skin with antioxidant benefit, you can try out this Vitamin C from O.S.T.

Have you tried any antioxidants in your skincare routine? Let me know in the comments below and until then, I'll see you later~
