Celebrity product endorsement has always been popular and the impact it can have was shown this week after a wrinkle serum praised by Jennifer Lopez flew off the shelves in the UK in just a few hours.

After the 'On The Floor' beauty revealed that she swears by B. Flawless Targeted Wrinkle Filler to keep her skin looking youthful and glowing, high street cosmetics retailer stocked the product for a mere £9.99 and within hours of it being made available it had completely sold out both online and in stores.

Superdrug Director Simon Comins opened up about the product and the sales boost it has seen since being discussed by JLo: "We can't stock this product fast enough; it literally just keeps selling out."

"Customers know it's the real deal and actually works so it seems they're spreading the news to their friends. It's great to offer our customers a Hollywood ingredient for just £9.99."
