I suffer for dehydrated skin, I am only 26 so this isn't just for mature skin. I really couldn't live without this product. I apply it at night underneath my moisturizer. I find it very easy to apply, it is very light and just like water. I don't find it oily at all! I only use between 2-5 drops a day, depending on the season, so even though it is very expensive I think it is worth it as it lasts forever. Would recommend it to anyone who suffers from dull dehydrated skin, which is not necesssarily the same as dry.
