I tried Biokos Age Renew Revitalising Serum 2.5 years ago and in hooked. It has a lovely fragrance that isn't overpowering. I use it on my neck and face and it absorbs easily and feels wonderful. I Di think that it helps with the lines on my neck, as my neck isn't as wrinkly after ice applied it. I'm 69 and have what's been bothered with deep neck furrows. I have since bought the day and night cream and I'm very happy with both of those creams too.
