Update!
Hi everyone
I have some news! I went on to the Estee Lauder website, and did live chat with one of the assistants, who talked me through the Double Wear product that some of you recommended. She even told me, after asking some questions, what colour foundation I would need. Needless to say, I was a little reluctant to buy a colour based on what she'd told me without seeing me, so got my lovely husband to take me into town briefly to visit Debenhams and the E. Lauder counter. The young lady there gave me a couple of samples, one of which is absolutely perfect, and surprisingly was the exact shade that the assistant on line had recommended. I came home and tried it and it's AMAZING! That afternoon I had 3 hot flushes making my hair drip but the make up stayed put! I was gobsmacked! Needless to say, I shall be investing in the product for longer term wear, and just to share what I've learned, if you want to try Estee Lauder products, you can order online, and if it's the wrong colour, or doesn't suit, you can send it back and they'll even pay the p&p. You can't ask for better than that, so well done all who recommended their product, and to E.L. for their EXCELLENT service.
