It's not really safe to lay out in the sun anymore as it has been proven to cause skin cancer. If you feel you must lay out and get a tan however, then the amount of time needed to get a golden glow depends on your skin. Some people (like me) will never tan. We do nothing but burn and peel in the sun regardless of how much sunblock, I will burn. Others (like my sister) can lay out for 20 minutes and she looks awesome with the beginnings of a gorgeous tan line.
