So the wrinkles have been there for a while, but now they're looking like furrows. From 45 onwards, our skin becomes less firm and supple and our skin tone loses its uniform glow. And there's more... signs of tiredness; dark circles and bags; dig in their heels. Applying an anti-ageing day and night cream will help to prevent sagging, particularly if they include fruit acids, vitamin A, retinol and hyaluronic acid. All of these skin-friendly active ingredients will smoothe and brighten your complexion. They work on a deeper level to stimulate cell exchange and boost skin cell renewal. You should also start using a serum for a few weeks at a time. They're twice as concentrated as creams and, depending on the state of your skin, work a treat when we're worn out or dealing with seasonal changes.
