SPF Guide





Babies under one year should not be exposed to direct sunlight, as their skin is extremely delicate. Ensure that babies and very small children are kept in the shade. Wearing protective clothing, including a hat, and using a high SPF (higher than SPF 30) is important for babies.


Children should limit their exposure to the sun. Avoid sun exposure between 11 am and 3 pm. Wearing protective clothing, including a hat and sun glasses, and using a high SPF (higher than SPF 30) is important for children.

Everyone should avoid sun exposure between 11am and 3pm, when the sun is at its strongest and poses the highest risk of sunburn.

Which SPF is right for you?
To work out which SPF is right for you, use this simple equation. Determine your skin type, take the number of minutes that your skin will be exposed to the sun and divide this by the time your skin will begin to burn without protection. The result is the SPF that you should apply. If this SPF is not available, then always round up to a higher one (see table above).

Gemma is Fair and therefore her skins burn time without protection is 10 minutes
She plans to spend 3 hours in the sunshine
3 hours = 180 min. 180 min / 10 min = 18
SPF 18 is not available, the nearest SPF to 18, is 20, so Gemma should use SPF 20

How much time will you spend soaking up the sunshine?
Think about the glorious day ahead. Will it be hours of lounging by the pool, or a quick walk in the park or along the beach? However you plan to make the most of the sunshine, simply add up the number of minutes that your skin will be exposed - don’t forget to count the time that you’ll be in the shade, when the sun’s harmful rays can still reach you.

The best way to apply sun protection
Always apply about 3-4 tablespoons of your sun care product at least 20 minutes before you start soaking up the sunshine. Any less than that will reduce your level of protection and you may burn. Frequent re-application throughout the day is also a must and you should also be mindful that a swim in the sea or a dip in the pool will affect your protection – especially if you towel dry.
