Having used a Shiseido face serum before, which left my skin very dry. I was sceptical about using this incase it happened again, but to my suprise it's very nourishing, kind to my skin, smells lovely and a little goes a long way. Admittedly in the short time I've been using it I haven't noticed a vast difference in the reduction of dark marks on my face and neck, but the areas that I applied it are incredibly soft and hydrated and left any deep lines looking slightly softer in appearance. I think with longer use I'll see great results and proving this to be a wise investment in my beauty regime!
