With the recent spell of warm, sunny weather coming to an end, some scorched Britons will be glad of the respite.
Many will be nursing reddened skin and awkward tan lines after catching a few too many rays over the past few days - with some sharing their sun-screen fails on social media.
Lewis Reed, 27, from Brighton, didn't wear any sun cream - claiming he isn't fond of the sticky lotion - when he went out for a picnic on the beach with his mother.
But after an hour-and-a-half, he was mortified when his legs turned bright red and began to peel and blister.

He shared photos of his painful-looking burns on Twitter last weekend with the caption: 'When people ask me why I want to sit in the shade I show them these photos.'
Lewis is not alone; Jack Eddie, from Barnsley, shared a photo of his patchy back on Sunday, writing: 'Top tip don't leave your eight-year-old daughter in charge of putting sun cream on ya back hahaha FFS (sic).'
Dave Hammond, from Desford, replied to Lewis' tweet with a snap of his own beetroot-red arms and face, tweeting: 'Erm yeah feel your pain.'
Mother-of-three Sarah Draper, from Ilkeston, admitted she too should have asked for assistance with applying sun-screen to her back. She tweeted a snap of painful-looking strap marks on her back, adding: 'Maybe I should of asked a neighbour for help with sun cream (sic).'
But while these images are amusing to look at, the consequences of overdoing it in the sunshine can be very serious. Emma Coleman, a dermatology registered general nurse told FEMAIL that just one sunburn incident can alter the way the skin functions.

'UVB rays from sunlight are more likely to cause sunburn compared to UVA light, which is essentially inflammed, immunosuppressed skin,' she said.
'Worryingly, the immune system remains suppressed for a period of time after the exposure. This means that even one sunburn incident can alter the way the skin is functioning, in particular genetic material formation is stunted meaning that cell division and shape are altered, and mitochondria - skin cell's power houses - are debilitated. This is why we see advanced ageing associated with sun exposure.'
She told how the back area is 'highly associated with malignant melanoma', while the chest is 'very delicate' because the skin is thin. Emma said: 'It's important to protect the décolletage whenever exposed with a broad spectrum sunscreen. I regularly see clients with pigmentation and deep lines on their chests due to sun damage.'
Emma, who has her own skincare and beauty range, told FEMAIL: 'A history of sunburns and a young age of first sunburn incidence are associated with an increased risk of basal cell carcinoma development, and squamous cell carcinoma risk is largely increased in those with light-coloured eyes and fair to auburn hair colour.

Ciara Nic Eoghagáin, of Manchester, shared a snap of her reddened chest, writing: 'Do you ever just go outside in the sun with suncream on for two hours and this happens? Or just me?'
'This is because those with Fitzpatrick skin types of IV and above have higher melanin levels naturally, and melanin is thought to exert a protective effect on skin.
'Sunburn in childhood equates to a five-fold increased risk of developing malignant melanoma, according to one Italian study.'

How to ease sunburn
Get out of the sun as soon as possible
Cool your skin with a cool shower, bath or damp towel (take care not to let a baby or young child get too cold)
Apply aftersun cream or spray, like aloe vera
Drink plenty of water to cool down and prevent dehydration
Take painkillers, such as paracetamol or ibuprofen for any pain
Cover sunburnt skin from direct sunlight until skin has fully healed
Use petroleum jelly on sunburnt skin
Put ice or ice packs on sunburnt skin
Pop any blisters
Scratch or try to remove peeling skin
Wear tight-fitting clothes over sunburnt skin

Twitter user Christoff, from Wigan, told how he managed to get sunburnt on his face while painting his garden fences, despite wearing a cap.
And Jamie, from Manchester, tweeted a photo of his pink complexion, writing: 'Wear suncream folks!'
Emma recommended wearing sunscreen every day throughout the year - even when it's raining.
For those suffering from sun burn, she suggested frequent cool showers or baths and applying aloe vera gel to the affected area.
'This won't cause overheating of the skin when applied and has a cooling effect for itchy and burning skin,' she explained.
'A lidocaine-containing Lanolin product can also help with severe pain. Oral anti-inflammatories for three days will help with initial pain and blisters should be left to heal themselves. Application of fan therapy to further cool the skin will aid comfort.'
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.

Skin cancer - the facts
There are two main types of skin cancer: melanoma and non-melanoma. The latter is far the most common and can usually be treated successfully.
Sun exposure causes skin cancer because of the ultraviolet (UV) radiation in sunshine. There are three main types of UV radiation, UVA, UVB, and UVC.
UVA and UVB can cause skin damage including sunburn and premature ageing of the skin. This damage can lead to skin cancer. Cumulative sun exposure is the most important risk factor for non-melanoma skin cancer.
Some evidence suggests that sunburn or intense exposure to sun in childhood particularly increase the risk of developing melanoma.
Are some people more at risk than others?
You may be more at risk depending on your skin colour. Melanin is a protective pigment that is produced within the skin and helps protect the deeper layers of the skin from the harmful effects of sun.
Fair skin contains less melanin than dark skin and so fair skinned people have an increased risk of developing skin cancer.
The tell tale signs
Around one third of all melanomas develop from normal moles so it is important to be aware of any sudden changes in moles.
How to spot a melanoma
The mole will have an irregular shape, ragged and irregular edge, be a mixture of colours including brown, black and blue, larger than 5mm across and will enlarge over a six-week period.
The symptoms of a non-melanoma skin cancer are: a new growth or sore that does not heal within four weeks, a spot or sore that continues to itch or scab and persistent skin ulcers that are not explained by other causes.
Top tips for sun safety
• Avoid the midday sun between 11am and 3pm.
• Don't be fooled by a cool breeze or light cloud: you can still get burnt.
• Cover up in the sun with loose cotton clothes, a wide brimmed hat and sunglasses with UV protection.
• Protect yourself while swimming.
• Look out for the solar UV index on the TV weather forecasts.
• Children need extra protection.
• Avoids using artificial tanning equipment to get a tan.
