Your Questions Answered

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.
If you apply a sunscreen with SPF30 this means that you can stay in the sun 30 times longer than you could without sunscreen. However, you must use sunscreen as directed and ensure enough sunscreen is initially applied (35ml) for maximum coverage. Higher factors should not be used to increase your time in the sun, but to increase your level of protection.

Yes, sunscreen is still required. Even when the sky is overcast, UV radiation levels are still at 80% of their normal levels. The temperature can be deceptive - a breeze can keep you cool, but it doesn’t affect UV levels. Look up the UV index for your area to make sure you’re using protection when you need to be.

According to Cancer Research UK, this is not true. They claim: ’Cost is no indication of better protection. You may simply be paying for a brand name. All types are tested and the cheaper brands are just as effective if used properly.’ Calypso Press and Protect Sun Lotion SPF30 was found to be one of the cheapest and most effective sun creams and was chosen by Which? as its “Best Buy Sunscreen” for 2014 and 2015.

Yes! They keep their effectiveness by binding more strongly to the skin, so they last longer. Our Calypso Once A Day range is rigorously tested to ensure that even after 8 hours of wear, it still offers the SPF on the label. You should be extra careful to apply enough of the product and make sure all exposed skin is covered. However, please remember that even water-resistant Once A Day sunscreens can still be washed off if you spend a long time in the water or if you dry yourself with a towel, so you might need to reapply.

We’re pleased to say that we don’t test any of our products on animals. What's more, we don’t buy ingredients that have been tested on animals by another manufacturer. So you can buy Calypso confident in the knowledge that your sun care is cruelty-free.
All our products are suitable for vegetarians. However, some contain ingredients like keratin (made from sheep’s wool) or beeswax (made by bees) that vegans may wish to avoid. If you have any questions about animal ingredients, please get in touch.

There are two types of ultraviolet radiation which can harm our skin – UVA and UVB. Only UVB causes burning, but both types damage our skin, so good sunscreens should protect against both. However, SPF only measures UVB protection, so you have to check to make sure your sunscreen offers UVA protection too. There are lots of different UVA measuring systems around the world. We use the European standard – look for the letters UVA inside a circle. This symbol means that a product meets the EU-recommended level of UVA protection.

Calypso has always used the Europe-wide standard UVA symbol (the letters UVA inside a circle) on its packaging. This is a legal requirement through Cosmetics Europe and ensures the correct balance between UVA and UVB on products. All other systems are not legally binding and do not follow the Cosmetics European Directive.

Yes you can. All ingredients in the Calypso product range have been approved as cosmetic ingredients.
