What an amazing serum. I've been using this for just over a week now I have had problems with oiliness around my nose and chin area for years I've tried many different products but this has started helping me with those problem areas already. I've noticed a visible difference to my skin in such a short period of time and I will definitely continue to use. Even my blemishes seem to be fading away. I'm looking forward to continuing to see an improvement in my skin. At the moment I have only been using once a day in the morning after cleansing. Just wow.
