OST C20 Original Pure Vitamin C20 Serum

Hi Everyone!

This has been a week really heavy and probably the next week probably will be worse so I need continue posting because is the only way to maintain my sanity. Sincerely I prefer the books over the persons as strange as this may sound. I am tired to have to deal with stupid people. With a lot of effort I can deal with my own family that by the way lately has been a huge headache. People who talk when the should not talk. But I am happy at least now because despite everything I´m here publishing this review. This is one of my most delayed reviews and that was because I always found the way to publish another review instead of this.

My first experience with a serum with ascorbic acid like the rincipal ingredient was in 2013 and I found my true love something like my holy grail. But It was a sponsored product and sincerely the product was pricey. But obviously It wasn´t this product. After read many reviews about this product I decided the last yeay that was my moment for try this product and I must confess that for that time my skin was very troubled due stress, hormones and bad nutrition. So I decided try this product. I bought this product and I knew that this product is very propense to the sun and the warm and hot weather so even before opnened I decided put it in the refrigerator first because the weather in my country is really hot. And an important fact thr ascorbic acid oxidizes with heat.

I tried this product alone without use any other product in my skin care routine only cleanser and this product because like I have sensitive skin I wanted know how my skin reactioned only to this product and after that incoporate slowly the other products from my routine. The first day I felt an itch specially in the most sensitive parts of my skin face like my cheeks and around my mouth and nose but that was momentary. I had my doubts but to the next day the redness was very reduced since the first use of this product that was only a day before.

The second day I didn´t felt any itch in my skin and I was relieved. I incoporated my toner and the product continued working perfectly. I saw a reduced appeareance of my large pores and of course my skin looked more tight after each application. The redness was reduced to nothing. One of my favorites things about this product is that prevent the pparition of primples in my skin and since I discovered that I was in the heaven. Sincerely I really recommend this product I used his for several months in my oily sensitive skin adn this product doesn´t caused me any allergic reaction. Like always you should know that each body is different and even If you have the same type of skin than mine you should be careful.

By the way I never use this product during day I only use this serum for my night skin care routine. And puting this product in my refrigerator I prevented the oxidation of this serum. A bottle last me at least three months so I guess this is a good investment ebcause the price is around $15 to $20 USD. I highly recommend this product and by the way in the next months I hope be publishing the review about this same product with renewed name because this is my holy grail. This product contains 20% of vitamin c and that means that provides a good whitening and antioxidant effect and I saw that with the reduction of my recent scars of primples. 

Well my lovelies that was all for today. An amazing product for a great price (~ ̄▽ ̄)~ Now I want continue using more serums 
with good concentrations of vitamin c like thisヾ(@^▽^@)ノ

I hope you enjoyed this review -・*☆
