If you browse Boots' website on the regular, you'll know that the high street health and beauty retailer often slashes the price of its bestselling beauty, teeth whitening products, fragrance and skincare products to just £10 every Tuesday in its weekly price drop. Popular brands include No7, Huda Beauty, REN Skincare and Olay, so it's always worth sticking it out to see if your favourite product, or something you've always wanted to check out, has been discounted.

Luckily, Boots has extended its £10 Tuesday sale to be every day until May 7, meaning shoppers can nab high-end products for just £10, all week long. But there is a slight catch, as the extended sale is for Advantage Card members only.

One popular product that is bound to be a hit with beauty buffs is the The Olay Regenerist Overnight Miracle Firming Face Mask, which normally costs £34 for a full size pot. The anti-wrinkle cream promises you will wake up to plumper and firmer feeling skin after just one application.

Its fast-absorbing and non-greasy formula uses Advanced Amino-Peptide Complex, and is designed to revive the skin's youthful elasticity while you sleep. It is said that over time, he skin will appear revitalised & younger with reduced visible signs of stress and fatigue.

Now £10, the 'fast acting' anti-ageing OIay cream has a near-perfect overall rating of 4.5 stars out of five on the Boots website, and has blown those away who have tried it. One beauty lover wrote: "This is amazing I wish I had bought this years ago. It does exactly what it says it firms the skin and is not oily at all. I have used this for a week and already see the difference. I definitely recommend this product."

A second said: "Fabulous product with almost immediate results. Skin visibly brighter and firmer." "Amazing overnight face cream, results within days, clear, soft skin feeling refreshed," raved a third.

A fourth said: "It’s a yes from me. Really makes a difference after the first application and I can’t wait to see the results after four weeks of continuous use. One day I realised I hadn’t moisturised my face that morning and it still felt smooth and soft. I still have lots of smile lines (wrinkles) but I’m not expecting miracles, just pleased with the overall effect. £10 Tuesday, thank you."

"Feeling rehydrated after just a few applications, would highly recommend its light non-greasy and packs a punch," somebody else said of the £17 anti-wrinkle cream. "I love this. I bought it to try out on the Tuesday offer not really expecting much but was very pleasantly surprise to notice a difference to my skin after the first use," said yet another impressed Boots customer.

The L'Oreal Paris Revitalift Filler Hyaluronic Acid Anti Ageing Night Cream is another alternative to the Olay Regenerist overnight cream. The moisturiser has been flooded with praise by hundreds of those who have tried it. Or take a look at Amazon's COSRX Advanced Snail 96 Mucin Power Essence, which is currently £11.28 instead of £21.99. After being showered with more than 40,000 glowing five-star reviews, the serum has earned cult status, and is unsurprisingly Amazon's bestseller in anti-ageing products.
