Skincare Review | O.S.T Original Pure Vitamin C20 Serum
The consistency of the product is runny but with a bit of thickness to it. The color is slightly yellowish but is transparent. Though it feels sticky when first applied, after a minute or so, you can feel that it is being absorbed by the skin. It is best used with or after toner and before moisturizer (as stated above). I prefer water-based moisturizer to be used with this. Based on the photo below, you can see that my skin absorbed the serum really well. Few drops (2-3) is enough for the entire face.
My nose area became clearer and it looked and felt smoother after 1 week of using this serum. My pimple scars lightened. Redness on my cheeks became less visible. So far, I have not seen any pore tightening effect. well, my pores are stubborn when the weather it hot. They have the tendency to be more visible. I have yet to see other effects in the coming days as I continue on using this serum. I promise to update this post after emptying the bottle.
