OST Original Pure Vitamin C20 Serum [review]

I've never use any skin serum diligently these past years..

Because I'm not a person who like to apply too many skincare layers on my face XD

But, you know what? Serum is an important part of skincare routine, and it is NOT just another layer in your skin routine.. 

Well, for those of you who doesn't know the definition of serum..

Serums are thick liquid-like products with active ingredients like vitamins and anti-oxidants that are formulated with smaller molecules so the can penetrate deep into the skin. Serums are designed to penetrate and treat various skin conditions, such as redness, dehydration or lack of firmness, wrinkles, dark spots, or to brighten the skin (source: http://www.apivita.com/new/natural-serum/)

Okay, without further ado, let me review my current favorite serum at the moment ^_^

OST Original Pure Vitamin C20 Serum

Packaging

Actually I have owned this as from May 2013, but since I'm not a serum person (I'm too lazy ~_~), finally I was started to use this serum regularly around 2-3 months ago. When I received the package for the first time, the serum bottle still secured tightly in this kind of lid. It has leaked a bit and the spilled out serum became harden around the lid o_o

Texture & Scent

Anyway, it has very runny texture and easy to blend onto my face. The serum also can absorbs into my skin very well ^^ For the scent, it slightly reminds me with coffee scent.. I don't know about you, but some people said the scent is too strong. Personally for me, its scent isn't too strong and doesn't bothers me at all.

Most of time, I always use this serum before I go to bed. I'm barely use this serum in the morning (oh lazy me, LOL)

When I captured photos for this review, unfortunately the serum has oxidized.. to make it clear, the real color of this serum is like this:

Overall Thoughts:

I love this O.S.T Original Pure Vitamin C20 Serum ♥ It has nice runny texture, adsorbs into my skin really well and leaves matte skin result few minutes later. It's not greasy nor sticky at all ♥

My skin's complexion is getting better day by day. After using this for around 2 months, my skin becomes really smooth, moist and bouncy XD I'm so in love with my current skin condition. I also barely have pimples (even in my period). Psst, I can't stop to touch my skin :3 LOL

I know what you guys want from me :p It might be before and after photos?

These are sneak peek of my previous & current skin condition ^^

BEFORE  (end of Nov '13)

AFTER (February 2014)

I guess I only have sunscreen on my face for this photo. No makeup & no overly-photoshopped!

I only adjust the brightness and skin tone :) because it was a bit yellowish compared than in real life.

What I love ♥

+ Not sticky

+ Not greasy

+ Improve my skin texture very well

+ Refine my skin (my skin becomes so smooth ♥)

+ Doesn't break out my skin

+ Reduce my pimples (even in my period)

+ Brightens my acne scars

+ It slightly reduces my blackheads

+ A little goes a long way

What I hate :/

- You should keep the bottle standing up, or the serum will leak from the lid

- The interlude between manufactured date & expiry date is only one year

- There's no offline store that sells this serum, you need to buy it via online

Rating:

Last but not least for this photo, I only used concealer & pressed powder, 

see how my skin condition improved well? ♥

Where to Buy this serum?

UPDATE:
I got information from my readers.
A serum should be finished within 1-2 months due to oxidation.
Better place it in fridge :)
Now my OST serum has oxidized and unfortunately I have to toss it out :((
It's a very good serum though.. If I knew this earlier, I would finish it earlier *sigh*
Anyway I got another new serum to replace this serum
Gonna give you further update when I'm done ^^
