I've been using this vitamin C on my face every day now for about a month or so. I'm starting to see overall positive results on my face. My uneven skin tone, due to sun damage, has begun to even out and the skin is looking much healthier. I also added vitamin E to my skin care about a week ago. Can't wait to see the added boost from that as well. Any excess serum I have on my hands I rub into my elbows and my hands. I'm seeing great improvement there as well. I highly recommend adding this vitamin C to your skin care regimen!
