How long can you stay in the sun with sunscreen
A person with lightly pigmented skin who burns in 10 minutes would only be protected for about two and a half hours with SPF 15 (SPF 15 x 10 minutes = 150 minutes). If you apply an SPF 15 sunscreen, you will be protected for approximately 300 minutes, or five hours (SPF 15 x 20 minutes = 300 minutes).
