I love the new Simply Pure range from Superdrug. I use the products with the blue labels, they are for dehydrated skin. My skin is much softer and a bit plumper since using the serum twice a day under moisturiser. And it costs a whole two pounds 99p!
Lancome's Visionaire is really nice but rather expensive. They've just brought out a Visionaire Foundation, this week, which is gorgeous and contains the serum at about 50% of the strength so it still treats your skin. It also comes with a concealer built into the lid so you can get more cover where you need it. I think the foundation is £35. Again, pricey but 3 products in 1.
Are you using a moisturiser over the serum? I never used to because I felt too greasy but I've now switched to a lighter moisturiser and its all feels much nicer, apparently you should always use a moisturiser over a serum, the lady at Dior told me so. I use the boots no 7 one and have done for years, have had samples of Lancôme Visionnaire and Dior both very nice but I bet very expensive.
