4 Tips on How to Choose the SPF for Sunscreen
3. Pick a Sunscreen based on how long you will be exposed to the sun
If you are heading to the beach and you will be there for a long time, then it is wise to pick a sunscreen with a higher SPF and to apply it as often as possible. If it is really hot and you are wearing a bikini you should apply it every twenty minutes at least to avoid getting burnt in the sun.
4. Pick a sunscreen based on the altitude you are in
The SPF factor also changes depends on how high you are. Sunlight affects your body in different ways in different places. The way you get burnt and the amount of burn differ whether you are in the beach, the mountains or in the snow. Pick a sunscreen with the appropriate SPF depending on how direct and how harsh the sunlight falls on your skin.
You do not have to automatically go for a sunscreen with a high SPF factor or a low SPF factor because of your skin color. Since a sunscreen with SPF of 15 protects your skin 92% and no sunscreen offers 100% protection against sunburn, a higher SPF is not always the solution. Think of your skin type, the place and always consult a dermatologist before you lather on the sunscreen. The best thing to do is apply sunscreen at regular intervals and wear protective gear when you are exposed to the sun for longer periods.
