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.

'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.'
