Calypso Once a Day Sun Protection Lotion with SPF 30

Product Information

Professor Brian Diffey adds that sun creams generally offer ‘very good’ water resistance these days (though be aware water resistance claims also come with caveats, and the products we tested didn't hold up well to real-life conditions in our 2016 investigation), which is good if you're planning on spending time in the pool or in the sea. But over the course of the day swimming will wash away some of the protection.

Important: Read the instructions carefully before use. Apply to clean dry skin, preferably after a shower. Apply evenly and generously 15 minutes before exposure to the sun, which will allow the product to bind with the skin and form a protective film against UVA/UVB rays. When used correctly, one application is sufficient for all day protection.Yes, you can - but you’ll also need to reapply frequently, just like you would if you were on the beach staying dry, and immediately after towel drying.

Calypso Once A Day may cause staining on certain fabrics and surfaces. Always cover seats and cushions. May discolour nail products. A spokesperson added: 'As with all sunscreens, it is important to follow the instructions for application and use; and sunscreen should not be used to intentionally stay longer in the sun. Sunscreen is just one part of a sun safe regime.' Boots

Use in the water - up to 40 minutes of water exposure (up to one hour for the kids version, and up to three hours if you opt for Boots Soltan Kids Once 3hr Waterplay Spray) So, if you are only applying your sunscreen once a day, you are at risk of spending hours in the sun with little or no protection to those areas of skin that may have been missed.'

This is because, she said, the length of protection can vary depending on a person's activities - including how much they sweat and whether they towel dry, for example.The only bad thing is it smells quite strong, like ammonia. So avoid your eyes! My first day I rubbed it all over my face and my eyes watered all day but from then I just avoided my eye area and it was great. Some regular sun creams also make my eyes water. We made multiple attempts to get in touch with Calypso, but the brand did not respond to any of our questions or send us a comment. Riemann SPF stands for Sun Protection Factor and represents the sunscreen’s ability to protect your skin from the sun’s rays in addition to your skin’s natural protection. Depending on your skin type, hair colour, eye colour and location, you may be able to stay in the sun for 10 minutes without burning.
