National Healthy Skin Month is a timely reminder that sun protection is important year-round, not just in the summer. One of the most common misconceptions about skin health is the idea of a “healthy tan.” Many people believe developing a "base tan” helps protect against sunburn and is a healthier way to enjoy the sun. “While it is true that a tan may slightly reduce the risk of burning, it’s important to remember that a tan itself is a sign of sun damage. A tan indicates that your skin has already been harmed by ultraviolet (UV) radiation,” explained Dr. Trent Gay with Blount Memorial Physicians Group – Dermatology.
The misconception of a “healthy tan” stems from misunderstanding how skin cancer develops. “While severe sunburns increase the risk of melanoma, the deadliest form of skin cancer, other types such as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), are more likely to occur from cumulative sun exposure. Since BCCs and SCCs make up the majority of skin cancer cases, prolonged sun exposure is a significant concern. A ‘base tan’ also increases your overall sun exposure, raising your risk for skin cancer over time,” Gay said.
A healthier approach to enjoying time outdoors is to prioritize sun protection. Sunscreen is one of the most accessible and effective defenses against UV damage. Dermatologists recommend using sunscreen with a sun protection factor (SPF) of at least 30, though higher SPFs provide even better protection. “Most people don't apply enough sunscreen to achieve the full protection indicated on the bottle, so opting for a higher SPF offers some added security. It's also important to reapply sunscreen every two to three hours, especially if you're swimming or sweating. Lotions and creams often provide more reliable coverage than sprays, which can provide uneven coverage or be affected by wind,” Gay advises. Always check the expiration date on sunscreen to ensure it is still effective.
“Wearing sun-protective clothing is another excellent way to guard against UV exposure. Many lines now offer stylish and comfortable options designed specifically for sun protection. Brands such as Columbia PFG®, Coolibar® and Solumbra® offer sun-protective clothing for those who prefer not to rely solely on sunscreen or who may forget to reapply,” Gay added. Wide-brimmed hats, UV-protective sunglasses and long sleeves also can provide additional protection, especially during peak sunlight hours from noon to 4 p.m.
“Another tool for protecting skin from UV damage is an over-the-counter supplement called Heliocare® which contains polypodium leucotomos, an active ingredient derived from a fern. Studies have shown that when taken orally, this supplement can help reduce the harmful effects of UV radiation by depositing the active ingredient in the skin,” Gay said. While Heliocare® is not a replacement for sunscreen, it’s a helpful addition for those who may not apply or reapply sunscreen consistently.
