We firmly encourage your new year to be all about recuperating from a hectic festive season, but even if you’ve been religiously getting your eight hours of sleep each night it can take a little while longer for your skin to get the memo that you’re well rested now. If you’ve been doing everything right but you’re still struggling with those pesky dark circles and puffy, tired-looking under eyes (and don’t forget, sometimes genetics can play a part in it too), then it might be time to invest in a brand new eye serum to give those dark circles a helping hand and show them the door.
