We all know it and we can't say it enough... whatever our age, exposure to the sun is not good for our skin. At 20, we want the perfect tan, but not at the expense of getting wrinkles or losing our naturally plump complexion. And it's at this age when you need to take care : sunburns during our youth will later cause premature wrinkles, sun allergies, liver spots and even skin cancer. So it's vital you use a sunscreen with an SPF of between 30 to 50 and reapply every two hours and after taking a dip. And avoid sunbathing between 2 and 4pm when the sun's rays are at their strongest. Don't worry, this won't stop you from getting a golden tan, we promise ! Some of you may be tempted to avoid sunscreen to blitz spotty skin, as the sun does make skin drier and thicker, keepingpimples at bay. However, the little devils will come back in force when the season changes. The answer's simple : apply a sunscreen. It will regulate sebum production and boost your skin tone. You'll get a great, sunburn-free tan, and prevent the appearance of pimples once the holidays are over. You've got nothing to lose and everything to gain...
