Wrong timing, missed symbol and other common sunscreen mistakes

A GP has revealed five common sunscreen mistakes that could put you at risk of harmful UV rays during the summer sun. Dr Stephanie Ooi, a GP at MyHealthcare Clinic, says many people are unaware of the proper precautions that should be taken to guard against sun damage and skin cancer.

As people up and down the country ready themselves for warmer temperatures, Dr Ooi says it’s important to stay safe, and has listed five common mistakes that *people often make.

Not applying enough

Dr Ooi said: “Most of us don’t put on enough sunscreen. To properly protect your face you should apply two finger lengths of sun cream and for your body it’s a whole shot glass. If you use a spray bottle or roll-on you should be applying several passes or spritzes in each area to provide adequate protection.

“When it comes to children, those under six months should be kept out of the sun entirely. With older children there aren’t any specific rules but you should apply sunscreen liberally. More is more! Clothes will provide some protection but don’t forget to go under clothing edges to ensure you have good coverage across the entire body.”

Not using a high enough SPF

Dr Ooi, a mother-of-two who offers handy hints on her Instagram page @the_gp_mum, says she always recommends using SPF 50. She said: “Choose the highest SPF possible to give yourself the best protection. Some people choose lower SPFs because they think this will boost their body’s levels of vitamin D, but studies have shown vitamin D levels aren’t affected by a higher SPF sunscreen.”

The body creates vitamin D, which helps keep bones and muscles healthy, from sunlight on the skin when outdoors. If you are worried you can always take a daily vitamin D supplement. The NHS recommends taking 10mcg (or 400 units) daily during the winter months.”

Applying too late prior to sun exposure

When you’re in a rush to get outside and enjoy the weather it can be tempting to apply sunscreen when you’re already basking in the sunshine. But Dr Ooi says people need to be wary of applying protection well before they are exposed to UV rays.

She said: “Sunscreen needs to be applied at least 30 minutes before going outside. On top of this, most will need to be reapplied every two hours. If you are swimming or sweating you will need to reapply protection even more frequently.”

Using expired sunscreen

Many of us are guilty of dipping into last year’s stock of sunscreen. But did you know it can expire? Dr Ooi said: “You can check by looking at the back of the bottle - there will be a jar symbol with a number. This corresponds to the number of months it can be open before being discarded.”

Thinking sunscreen makes you invincible

Sunscreen is a filter, not a block, so your skin can still be damaged. “The best protection is to stay out of the sun completely,” Dr Ooi explained, “especially during the hours when the sun is at its strongest, which is between 11am and 3pm.

“It’s not always possible to stay out of the sun so be sure to seek shade, wear a wide-brimmed hat and cover up with loose, breathable clothing. Remember, there is no such thing as a healthy tan.”
