When I was younger, I thought my face was oily all year round, but now that I'm in my mid-30s, I've started to experience some dryness in certain areas in the fall and winter. If I don't properly moisturize the corners of my eyes, they dry out easily, and I also feel dryness around my mouth. I was searching for a good primer that was both moisturizing and also covered pores, and I finally found it. This is it (lol). It doesn't really tone up my skin, but it evens out uneven skin tone and gives my pores a glossy, blurred look. The moisturizing power, as it's all-important, is simply amazing. I don't feel dry at all, and my skin feels hydrated all day long (personally, I thought this level of moisturizing power wouldn't be suitable for the summer when my skin is oily). I'm glad I can wear powder foundation and matte foundations, which are difficult to use in the winter, without being afraid. I think this primer is worth having in your arsenal for fall and winter. Clarins is known for its serums, fix mists, and lip oils, but I've learned that they also have some great base makeup products. This primer could do with a little more buzz...
