Retinol is a potent tool in my anti-ageing arsenal. I love Neostrata Skin Active Retinol + NAG Complex (£55, dermacaredirect.co.uk) because the vitamin is dripfed into skin, so it doesn’t cause any irritation when used three times a week. Once you reach 40, your skin needs nourishing every day to stay looking healthy. I apply ZENII Micronutrient Repair Night Cream (£75, zenii.co.uk) because it uses a kind of retinol that’s gentle enough to use every day to top up a stronger product. The skin around the eyes is thin so requires special care. Skinceuticals A.G.E. Eye Complex (£81.90, skinceuticals.co.uk) prevents sugar in the blood damaging the skin’s support structure via glycation. Blueberries help fight dark circles, too.
