I purchased the Clinique Pore Refining Solutions Instant Perfector this weekend and I am absolutely impressed with it. I see a difference in my skin immediately after application and the effect lasts the entire working day. Just some advice if anyone is interested in this product, they come in different colours for different skin tones. The shop assistant did not mention this to me so I ended up purchasing one that is too dark for my skin tone. Otherwise, an all round great product!
