Medik8 is well known for its bestselling hyaluronic acid serum, which shoppers say makes fine lines disappear within weeks. But the serum also exists in much more concentrated version, which promises to deliver even greater results.

Priced at £59, the Hydra B5 Intense is Medik8’s ultimate hyaluronic acid serum - you can also get it from Space NK (£59). Made with the popular active ingredient and vitamin B5, the formula has been enriched with superfood antioxidants and natural moisturising factors for profound skin rehydration.

It works to replenish and recharge the skin’s moisture levels, while leaving it visibly plumper and firmer. It also seeks to improve hydration in dry and dehydrated skins - both instantly and over time.

For enhanced results, you can use it alongside Medik8's £59 Advanced Day Ultimate Protect moisturiser. The serum has a 4.9 rating from across 768 reviews.

A very pleased shopper wrote: "I will buy this product over and over again, the glow is unreal, the hydration is just perfect and my skin this winter has been the best it’s been for a while! The serum soaks into your skin really well, leaving it super soft and glassy."

"I love this product! When I put it on my skin feels so good, it's super hydrated and it even takes the wrinkles away," another added, while a third commented: "Love this product, I'm 62 and I can really see a difference with the hydration of my skin and fine lines."

There has been very little criticism of the product, but some customers weren't as impressed with the results: "My skin still looks really dry with this serum. I have not seen any improvement and it causes any serum used on top of it to pill, even when I wait 30 minutes for it to dry."
