I have had this for a while and it is difficult to use. The directions say to dab on in localized areas and to put it on I used my fingers and the powder just disintegrated on my fingers. So, I eventually mixed it in with my serum and put it all over my face. Sadly, no difference with using it. I will finish the bottle as I hate to waste but will not be buying again.

This is difficult to use as directed. I mixed with a facial oil and sadly was not impressed with this product, no visible difference.

When I put this on at night under my night cream, I wake up in the morning with shallower wrinkles. I'm 35 so this is starting to mean a lot when I'm investing in skin care. It really feels like it's doing your skin good and the cumulative effect over a month is actually noticeable in skin tone and wrinkle depth. I don't yet have dark spots, it's the countering the smoking lines round my mouth I'm worried about and this Vitamin C Powder seems to be helping this. Very happy.
