I feel this is quite a decent serum for me, it does give an instant feel of hydration to my skin but I can't really say it made major improvements. Probably I may need to give more time (I'll update this post when I see results) for now, I feel it does nothing much but I'm still going to continue to use it as I like how easily it absorbs into the skin. I'm actually quite surprised that this serum did not cause me any zits because I'm pretty sensitive to Vitamin C but this one didn't.
