Skin Care Week: O.S.T. Original Pure Vitamin C20 Serum


The O.S.T. Original Pure Vitamin C20 Serum helps in anti-aging, tightening pores, brightening, reducing visibility of scars and hyperpigmentation, and removing blackheads. It comes in a brown medicine bottle with a screw cap. A cap dropper is also provided.

This is the fifth step in my evening routine after toner. I apply it all over my face, but with more product on the cheeks since I have more scars there and where I have pimple/s.Its consistency is slightly thick and feels sticky. The stickiness goes away when I follow with my routine.

I started using this last March 17 right after it arrived; not long enough yet to see any major difference. But it prevented scarring from occurring pimples and that’s awesome. 🙂 I don’t need more troublesome scars. 😆 I was hesitant to use this at first because of the brown bottle, but I learned that Vitamin C is sensitive to light and oxygen. It will oxidize when overexposed. Anyway, I’ll use this for a month or two and have before and after photos, so we can see if this is effective as it claims.

This is only available, so far, from online sellers. I got mine from a Shopee seller at PhP750.

      Hi, Renz! Yes, it’s been working wonderfully. I noticed there’s less visibility of old acne scars and the hyperpigmentation on my left cheek is almost gone. 🙂

        Wow. Great. Hehehe. I also got mine from a Shopee seller. Hoping it will work on me too. Do you apply moisturizer after you applied the serum? What moisturizer are you using? 🙂

          Sorry for not replying right away. ^^;;;

          I actually apply the COSRX Natural BHA Skin Returning Emulsion afterwards, but I let the Vitamin C set for a couple of minutes first. Then I’m done with my evening routine unless I want to put on a heavy moisturizer or overnight mask after the emulsion. I use the NUXE Crème Prodigieuse (Night) for my moisturizer. 🙂
