This weekend was a scorcher for many across the UK, but some Brits were ill-prepared for the hot weather and forgot to lather on the sun-screen.
Saturday was the hottest day of the year so far, with temperatures hitting a scorching 34C in London.
And some Brits failed to take proper precautions, soaking up the sun without protecting their skin from the potentially damaging rays.
Dozens took to social media to share photos of their epic tanning fails, from charred ankles and awkward strap marks, having been out in the hot sun without applying enough protective lotion.
But while these images are amusing to look at, the consequences of sunburn can be very serious.

Current research suggests that while many people who are severely sunburned as children never develop skin cancer, one blistering sunburn in childhood increases the risk of melanoma later on in life by 50 per cent.
Another study claims that white women who get five or more severe sunburns in their teens have double the risk of developing melanoma.
Skin cancer is the most common cancer in the UK and the numbers of new cases diagnosed each year are increasing.
Most non melanoma skin cancers are caused by exposure to the sun. This may be long term exposure or short periods of intense sun exposure and burning.

'Many individuals fail to understand just how impactful just one sunburn can be when it comes to your risk of developing skin cancer.

'Individuals with lighter skin and children should take extra care and keep themselves well protected from repeated episodes of sun exposure (i.e. burning each summer on your annual holiday), as it is considered a high risk factor for developing serious skin conditions such as, melanoma.
'Getting sunburnt doesn't mean you will definitely develop skin cancer, but sunburn can cause DNA damage in the skin, which in turn can be linked with the development of premalignant lesions (actinic keratoses) and skin cancers, such as Basal Cell Carcinoma, Squamous Cell Carcinoma and Melanoma.'
He added: 'Actively trying to get a sun tan is not advisable. During the summer months or whilst on holiday in sunnier climes, avoid sitting out in the middle of the day.
