Medik8 customers are in for quite the sweet deal, as they can bag a free complimentary gift when they purchase its latest Crystal Retinal - but they'll need to be fast. The celeb-approved skincare brand has recently launched the latest strength in its "age defying" range that is beloved by beauty buffs. With the "highest strength retinal yet", the serum has been designed to dramatically reduce wrinkles.

Launched earlier this week, the Crystal Retinal 24 is stronger than any of its predecessors. Classed as "expert" level, it's best ideal for those who have incorporated retinol into their skincare routine and progressed through the entire Crystal Retinal stages. Retailing at £109 for 30ml, Medik8's award-winning serum uses vitamin A to act "11 times faster" than regular retinol.

Its clinically proven formula is said to reduce wrinkles , while leaving skin firmer and brighter within as little as seven days. To celebrate the launch, the skincare firm has a "special gift" offer that gets customers a free 19ml Liquid Peptides Serum when they purchase the new Crystal Retinal 24. The travel-size bottle of this bestselling anti-wrinkle serum is worth £19, so we'd advise bagging it while you can.

It's not the only deal on offer, as new customers who sign up to the Medik8 newsletter can bag a 15 percent discount on the new Crystal Retinal. Once signed up, you'll be sent a limited time code that drops the price to just £92.65 - a total saving of £16.
