So when it comes to buying the right sun protection, it's crucial to know what it all means. The sun protection factor (SPF) indicates the amount of protection sun creams offer against UVB radiation. It tells you how much longer skin that's covered with the sun cream takes to redden in response to UV, compared with unprotected skin.

It all depends on what type of skin you have, but the NHS and Cancer Research UK both recommend you pick a product with an SPF of at least 30. If your skin burns easily, it's best to stay on the safe side and opt for a higher SPF. For kids and SPF for your face, it's recommended to use factor 50, as kids skin is more sensitive, and our faces are typically more exposed to the sun.

According to Which? UVA (ultraviolet A) is a type of ultraviolet radiation from the sun, which has been linked with premature ageing. Both UVA and UVB have been linked with skin cancer. UVB (ultraviolet B) is another type of radiation from the sun and is the main cause of sunburn. It has a shorter wavelength than UVA.

UVC (ultraviolet C) is the shortest form of UV radiation and the most dangerous to our skin, although luckily it cannot penetrate the earth's atmosphere. Of the UV rays that get through our atmosphere and can affect our skin, UVB makes up 5% and the other 95% is UVA.

The UVA seal indicates that a product meets the EU recommendation for sun creams to offer a UVA protection factor equivalent to at least a third of their SPF.
