It's fair to say that keeping your makeup in place during the warmer months can be tricky, and it can often feel like everything has melted away by the end of the day.
And, while you may not be a fan of wearing a full face of makeup in the heat anyway, some occasions (including summer weddings and big events) may call for it.
So, you can bet we're pretty tempted to snap up a £5 primer promising to help keep your base in place, which just so happens to be the current bestselling facial makeup product on Amazon.

The oil-free, transparent primer also promises to "mattify" your skin before you apply your base and is said to be "perfect for all skin tones and skin types, even dry, combination and oily skin".
As well as being a bestseller, the product has received rave reviews from shoppers on Amazon.
"Love this primer," wrote one customer. "I have really oily skin and usually have to blot my makeup halfway through the day, but that wasn't necessary with this primer.
"I wore it on a warm day to really make it work and it held up great. It kept my makeup in place all day."
Another added: "Great product, really good value and having tried quite expensive primers this is equally, if not better, at a fraction of the cost".
We don't know about you but we're certainly tempted to give it a try!
