Amazon Prime Big Deals Day might be over but there are still many incredible offers online – including an anti-ageing serum loved by 22,000 shoppers, which has been reduced to the lowest price we’ve seen.

A best-seller, Estee Lauder’s Advanced Night Repair Serum fights back years of ageing issues by infusing skin with 72 hours of moisture. It targets dryness and fine lines, to leave your complexion looking smoother, younger and radiant.

A standard 50ml bottle retails at £89 on Estee Lauder official website but Amazon is offering an incredible 60% discount off the product, dropping the price from £112.86 to £44.99, and that’s even cheaper than Debenhams’ price.

Facialist Donna Bartoli swore by this “miracle product” that protects by day and renews by night. She shared: “The Advanced Night Repair serum – one both my mum, my sister and I have used for over 30 years now. During that time, this formula has just got better and better. This is definitely one of the reasons why I always wake up looking renewed and radiant.

“See, our skin repairs itself during the night, so always keep it hydrated in the best environment and if you have been here [on Instagram] since the beginning, you will know how much I love this. I always say my morning starts the evening before and the Advanced Night Repair serum is integral to waking up to glowing skin.”

A second added: “The best [product] on the market, it cannot be beaten! Works on wrinkles and fine lines fantastically – a must-have.”

According to the beauty brand, every eight out of 10 people said wrinkles appeared diminished after three weeks and 89 percent of users testified saying their skin “felt firmer”, with one saying it’s: “Like silk on my skin.”

Another said the serum has now become a staple in her skincare routine, sharing: “My mum introduced this to me and I can’t look back now. My mom never had a skin care routine her entire life and in her 50s started using this. Her skin has impover so much and it looks more plump.”

Some suggested an alternative that claims to work better for their skin: the L’Oreal Age Perfect Cell Renew Midnight Regenerative Cream, £14.99, which has powerful skin-repairing ingredients like the Antioxidant Recovery Complex and vitamin E.

For others who want a quick-fix or something to use on-the-go, Trinny London’s Miracle Blur Lip and Line Filler (£26) works to “erase” lines around the lips and filter out enlarged pores under makeup
