I have oily, dry skin. I was concerned about my pores, so I bought this to incorporate vitamin C into my skincare routine. I didn't notice any notable effects. The minimum moisturizing power I'd expect from a serum is an oil, so in that respect it passes. However, my skin type isn't one that actively uses oil-based serums, so I'll use a different serum. I'm currently settling on Shiseido's Ultimune.
It has a smooth texture, but when you spread it, it becomes moisturizing. I use about four drops with the dropper every morning and evening as a serum. Since I started using it, the pores in the triangle area of my cheeks have become less noticeable. I plan to keep using it.
I've been using it for a few days, but I haven't noticed much change in my skin. I bought it hoping for a high concentration. It may be great that it's so concentrated, but it doesn't cause any skin irritation. However, adding just one product doesn't really fit into my lifestyle, so I'll continue using it for a little longer and see the results.
I use it together with Vitamin E from the same series. It has a smooth texture and is not sticky. I've only been using it for a few days, so I'm looking forward to seeing the results.
