We’ve all heard how retinol is the ultimate defence against skin ageing, but have you ever considered retinal? Both are forms of vitamin A, but retinal is up to 11 times more potent than retinol – and skincare brand Medik8 has launched an exclusive payday offer for our readers to experience it firsthand. From now until 11.59pm on Sunday (October 27), you can enjoy a 20% discount on any Medik8 product site wide by using the code NEWS20 at checkout.

This is the perfect chance to try Medik8’s Crystal Retinal face serum – a highly concentrated retinal formula that smooths, brightens, clears and firms your skin. In fact, this is the most powerful retinal-based formula available without a prescription. Despite its strength, 100% of those surveyed said the face serum was gentle on their skin – 97% also reported more youthful-looking skin, while 94% claimed they had never used a better night cream.

The serum comes in five strengths, and Medik8 suggests gradually increasing the strength you use. A 30ml tube at average strength is priced at £69, reduced to £55.20 with the NEWS20 code, reports the Manchester Evening News.

In the meantime, the Advanced Night Restore night cream, which is infused with ceramide, is the perfect follow-up to any retinol or retinal-based face serum. It plumps and firms the skin by replenishing lipids over time, while also providing deep moisturisation.

According to Medik8, the cream will combat free radicals and the damage they’ve caused, even out your complexion, and repair your skin’s natural moisture barrier. A 50ml tube is available for £59, or £47.20 with the 20% discount.

For deeper wrinkles, Medik8 suggests the Liquid Peptides serum, which normally costs £55 but is now £44 with the discount. This daily-use serum promises immediate results, tackling existing wrinkles and expression lines while helping to prevent new ones. The Liquid Peptides serum has an average rating of 4.9/5 from over 1,200 reviews. “Very easy to use, and I find 2 drops will cover the face, and it certainly feels good on the skin,” said a five-star review.

However, as everyone’s skin is unique, some customers may find the products less effective or gentle on their skin. “I had big hopes for the Liquid Peptides but I couldn’t use it,” said one such customer. “I don’t normally have sensitivity issues with face products but this was the exception. Too bad for me.” They noted, however, that the customer service was excellent. “I asked for a refund and got it right away, so 5 stars to the company.”

The Crystal Retinal formula has also been transformed into a potent eye cream, with the addition of ceramides for extra moisturising benefits. Medik8’s Crystal Retinal Ceramide Eye cream has seen 94% of users noticing a difference after just one night’s use. Even at its full price of £42, it drops to a more affordable £33.60 after the discount.

The Crystal Retinal serum is a hit among shoppers, boasting an impressive 4.8 stars from over 3,700 reviews. One satisfied customer praised the “amazing results” they achieved from using the product.

The eye cream also receives high praise, with an average rating of 4.8/5 from over 1,000 reviews. “It gave a fresh and bright appearance to my eyes. Buy it without hesitation. I will buy it when it runs out. Its texture and smell are wonderful,” said one pleased customer.

However, the Crystal Retinal Ceramide Eye Cream hasn’t worked wonders for everyone. A three-star review stated: “I have some pigmentation under my eyes and I think it’s starting to look a little lighter. The lines don’t really seem much different but as it’s an area that shows my age more, perhaps it needs a little more time.”

If you’re looking to try a different retinal, Facetheory’s Retinal Supreme MultiCream 0.1% is priced at £47. Alternatively, if you’re in need of a deeply hydrating overnight cream, Clinique’s Turnaround Overnight Revitalizing Moisturizer is available for £44 from Boots.

However, if you’re eager to experience Medik8’s groundbreaking retinal innovations firsthand, make sure to visit their website before 11.59pm on Sunday. Kickstart your Medik8 journey with the code NEWS20 to get the 20% discount.
