Fitness icon Jane Fonda has attributed her key to younger-looking appearance to skin hydration and her favourite is said to be a L'Oreal serum that is formulated to "target the deepest wrinkles". This week, Boots listed 155 beauty bargains and shoppers can find the said serum in the £10 deal.

The L'Oreal Age Perfect Cell Renew Midnight Serum, is now £25 off in a limited time deal. Formulated to support the skin cell renewal process with a non-sticky finish, the serum is effective on all skin tones and types.

Packed with moisture-boosting hyaluronic acid and a potent antioxidant recovery complex featuring neohesperidin for cell renewal and adenosine, renowned for tackling wrinkles, this serum offers daytime protection against free radicals, while providing nocturnal support when skin is most receptive to repair.

This budget-friendly gem also boasts a celebrity fan, including the Barbarella actress Jane Fonda, 87, who sports an enviable complexion. In a chat with Grazia, she revealed her fondness for applying the L'Oreal serum before hitting the hay.

"As you get older, skin tends to get drier-everything does," she noted, praising the serum for "having a lot of antioxidants and good things to hydrate the skin". She also commended the product's eco-friendly packaging, adding: "The brand is trying to use less plastic, be more sustainable, and are recycling products, so I think that's a good thing."

For fans of regal skincare, Rodial's highly acclaimed Bee Venom Super Serum which targets and improves uneven skin tones while giving wrinkles a plump makeover. Available on Amazon for £108.49 instead of £160, the serum comes with Royal approval – Princess Kate herself is said to have enjoyed the buzz around the bee venom facial.

And it seems that plenty of shoppers are on board, with one saying: "Using every third night as quite strong and moisturising afterwards and seems to be softening deepest wrinkles."

Another satisfied customer dubbed it an "affordable alternative to the Estee Lauer serum", sharing their experience: "It has a nice feel and have been using for just over a week, along with the Collagen creams. My skin has a more even skin tone and appears smoother."

However, some flagged bad experience as one suggested a redesign of the bottle due to the product's rich texture, explaining that the serum "won't come out because of the thick consistency". For those hunting overnight anti-ageing magic, Kiehl's Midnight Recovery Serum is another hot ticket item. Currently, a 50ml bottle is reduced from £66 to £59.40.
