The range consists of five products ranging from SPF10 to SPF50+ and we recommend our Once a Day SPF40 for kids as it is suitable for their delicate skin. I've never been brave enough to try using this for the full day while on holiday in sweltering hot sun and have applied sun cream after 6 hours to be on the safe side.

The use of the word durable, she added, aims to communicate its long lasting characteristics without 'promising [a] full day protection guarantee, with no need for reapplication. Sweating, swimming, towel drying, or rubbing your skin on an abrasive surface can all impact protection levels and how the sunscreen lasts. Don't just rely on sunscreen either: use clothing, hats, sunglasses to cover up, and seek shade, particularly when the sun is strongest, between 11am and 3pm - regardless of whether you are wearing sun cream. Back of pack instructions say you need to apply the sun cream generously 15 minutes before sun exposure and re-apply after towel drying or 'coming into contact with an abrasive surface'. I apply SPF 10 Once-a-day after breakfast and lie in the sun all day long, and never burn, unless my wife has missed a bit on my back!Apply a generous amount of sun cream - around one teaspoon per body part - at least 15 minutes before you go into the sun so it soaks in. They tend to be more expensive than standard sunscreen and claim to offer high and long lasting protection, usually by forming a more resistant film on the skin than standard sun cream.

Calypso Once a Day Sun Protection only needs to be applied to the skin once and protects you all day long. I used the factor 20 for a trip to Greece in April and I didn't burn and ended up with a lovely tan - I've found my preferred brand of sunscreen and can't see that I'll change any time soon!Of all the all-day lotions I've used over the years, I've found this to be the most easy to apply, and doesn't smell too bad, like some do. We're concerned that ‘once a day’ claims are still being made in 2022, despite the CTPA since encouraging brands to move away from such wording. It is always vital to be generous and vigilant when applying sunscreen, to ensure all exposed skin is protected.
