Sun damage does not just look bad with the wrinkles, blemishes and peeling, but also the health risks associated with it. Cancers like melanoma, basal cell carcinoma and squamous cell carcinoma are real threats that come with getting skin damage associated with the sun. That’s why you should always apply sunscreen whenever you’re outside (and don’t forget to re-apply every couple of hours too). Here are some lesser known things you should know about sunscreens:
Don’t skip important yet not obvious parts of your body – this means forearms, lips, and your ears. Whether you’re at the beach or the pool, these areas tend to be the most exposed to the sun and are quick to show signs of aging.
Water-resistant does not mean water impervious – “Waterproof” doesn’t mean it will last for a long time. Most formulas for sunscreens will wear off after 30 minutes or so when you are in the water, or if you are sweating. They also rub off when you use a towel after you finish swimming.
Use more than you think is needed – The American Academy of Dermatology conducted a study about sunscreen use and concluded that only up to half of people actually use the proper amount of sunscreen recommended. Anything less than an ounce is considered below the recommended amount.
Store your sunscreen in a cool and dry place – According to the FDA, sunscreens are required to last for at least three years as long as it’s not past the expiration date attached to the container. This means you should avoid storing sunscreens in areas that are within direct exposure to the sun or rain.
