A little goes a long way, so it’s quite cost-effective, and it’s lightweight so it absorbs easily. Also available on Amazon which I find very convenient!
I swear by environ. They have an eye gel which is a bit more than you’ve indicated at £65 but honestly the whole brand is superb. I wouldn’t be without it. Chellon is a great online stockist to use to buy.
I’ve recently been using the Estee Lauder advanced repair eye cream and although a little over budget I think its worth it. They often do really good deals when you buy a number of products or lots of complimentary items once you’ve spent a certain amount.
