Laura Mercier describes the tinted moisturising product as an 'effortless no-makeup makeup' that can help give you sheer coverage and it's one of the best foundations for a perfect dewy finish. 

The product is currently on sale and is £8 off at £32 instead of £40 at Look Fantastic, meaning it's the ideal last-minute purchase to add to your shopping cart before the last of the summer sun ends.
