A summer tan might seem like a priority but the sun causes more harm then what meets the surface. Even with an overcast sky, the sun still has penetrating rays that could damage your skin. One of every five people will get skin cancer in their lifetime. Having multiple sun burns in childhood increase this risk of attaining skin cancer in adulthood. By putting on sun screen, that can be the difference between health and sickness. Apply sunscreen at least thirty minutes before entering any type of water or else it will rub off and have no effect against the sun. If the UV index is above six, sun screen can only help so much, so limit the amount of sun time by staying in the shade or wearing clothing to protect your skin. To ensure you have esteem health, visit a dermatologist regularly and report anything irregular that you are concerned about.
