SPF I short for ‘sun protection factor’ and defines the level of protection that is applied to your skin. These sun filters are also what block the sun’s rays from damaging the skin. What factor you choose to use should depend on what your skin is subjected to during the day. It’s therefore not unimportant whether you reach for an SPF30 or SPF50 when getting ready in the morning. If your day includes low sun exposure, SPF30 should be sufficient protection. On the contrary, if you’re going to be outside for longer periods of time and especially in direct or strong sun, we always recommend that you cover your skin with a protecting layer of SPF50. Generally, if you’re in doubt, the safest choice is always SPF50, as this will provide the skin with the best protection. The essential part is that you’re sure that the sunscreen is evenly applied on your whole body and face.
