I have extremely oily skin, even though I am in my mid-30s. Even with primer, my foundation usually does not last. I know that moisturizing is important even for us oily skinned ladies, but most will make me even greasier. That is until I tried this lovely moisturizer from Kiehl's. It has a tingly, cooling sensation when first applied. After it dries, it provides the perfect matte canvas. Another great thing is the price. It is only $24.50 for a 4.2 fl.oz. bottle. That puts it in the same price range as drug store moisturizers. A little bit goes a long way, so keep in mind that you only need about a pea size amount to cover your face. It is paraben, fragrance, and colorant free, making it less likely to irritate most people's skin. I would give it 5 stars if only the mattifying effect would last all day, but it's the closest I have ever gotten (5-7 hours).
