As the weather becomes milder and temperatures rise, people flock to the outdoors. Summer activities like swimming, biking, hiking, and picnics put your skin at risk of sustaining serious sun damage. Exposure to the sun's rays can cause premature aging, the development of hyperpigmentation, and even lead to the development of skin cancer.
If you want to protect your skin against the ravages of sun exposure, you will need to use a sunscreen with a powerful SPF. Understanding what SPF is and what it really does will help you select the sunscreen that is best suited to meet your outdoor protection needs.
