Ever considered putting snail slime on your face? Well, this serum contains real snail essence which helps to hydrate whilst targeting dark spots and fine lines. A unique and powerful product, it's worth snapping up in the sale.

Speaking to Popsugar , Eva said "I live and die by hyaluronic acid with my Revitalift products from L'Oréal." She is an ambassador for the brand, so it's only natural she will be a fan of the products, but there are several videos of her using the serum in her everyday skincare routine .

It retails for £31.99, which although reasonable, isn't in everyone's budget for an everyday serum. But at less than £15, it's hard to resist adding one (or multiple) to your basket. If you're new to HA or a long time user, you're guaranteed to get along with its gentle formula - and the thousands of five star Amazon reviews prove it.

To avoid applying hyaluronic acid wrong and get best results from this serum, apply it to damp skin after cleansing and layer other products like SPF and moisturiser on top. If you have particularly dehydrated skin, hyaluronic acid stacking with a serum like the L'Oréal one could be the secret to rejuvenated skin.
