Regis expert offers 5 tips to best enjoy Colorado’s 300 days of yearly sunshine We are lucky to enjoy 300 days of sunshine each year in Colorado, but it is important to be diligent about protecting your skin from all of those UV rays. It is easier to think about sunscreen in the beautiful spring and summer months, but don’t forget we get plenty of sun in the fall and winter as well. Here are five tips to protect your skin while enjoying all Colorado has to offer: Remember to apply sunscreen at least 10 minutes before you are in the sun. It takes this amount of time for the sunscreen to be properly absorbed and ready to protect you. Sunscreen should be reapplied every two hours. It is important to reapply more often if swimming or sweating. During camping trips it is important to apply both sunscreen and insect repellent. Remember to apply sunscreen first, then repellent. Sunscreen needs to be applied more often than insect repellent. If you apply repellent to your skin as often as sunscreen, you may cause skin irritation. Take extra sunblock precaution when skiing or fishing. Reflection from snow and water enhances the UV rays you are receiving. No sunscreen blocks 100 percent of the UV rays, so remember the other important measures in skin protection: wearing protective clothing, hats and glasses. Sunscreen is studied and tested on undamaged skin. Skin that is already burned will not be as protected, so using other protective measures will be especially important.
