In support of Skin Cancer Awareness Month, Dermatology Clinic of Idaho’s dermatology experts are encouraging those throughout the Boise area to reconsider common sunscreen misconceptions that may be putting their skin at risk. Although sunscreen is a critical tool for protecting against harmful UV radiation, lingering myths continue to limit its effective use.
Here are five sunscreen myths it’s time to leave behind:
Myth #1: A higher SPF means you don’t need to reapply
The truth: No sunscreen provides all-day protection. Even high SPF formulas wear off over time. It is prudent to reapply sunscreen every two hours when out in the sun and again after getting out of the water or sweating.
Myth #2: Makeup with SPF is enough protection
The truth: While makeup containing SPF can offer an added layer of defense, most people don’t apply enough to achieve adequate protection. A broad-spectrum sunscreen (protects against both UVA and UVB rays) with an SPF of 30 or higher should always be applied underneath. Also, don’t neglect your neck, your ears, and your chest.
Myth #3: You can’t get sunburned through a window
The truth: While glass blocks UVB rays, it does not fully block UVA rays, which penetrate deeper into the skin and contribute to aging and skin cancer risk. Daily sunscreen use is important, even indoors and while driving.
Myth #4: Sunscreen blocks vitamin D production
The truth: In practice, sunscreen use does not completely prevent vitamin D absorption. Plus, vitamin D can be safely obtained through diet – such as fatty fish, fortified dairy products, and cereals – or through supplements when needed. The Skin Cancer Foundation stresses that exposing unprotected skin to sunlight to maintain vitamin D levels is not recommended, as it increases the risk of skin cancer and premature skin aging.
Myth #5: Sunscreen causes more harm than good
The truth: Misinformation about sunscreen ingredients has led to unnecessary concern. Sunscreens available in the U.S. are regulated for safety and play a vital role in preventing Skin Cancer. The risks of unprotected sun exposure far outweigh any potential concerns.
It’s important to know how sunscreen works. Sunscreens protect the skin from harmful ultraviolet (UV) radiation in two primary ways. Mineral (physical) sunscreens, typically made with ingredients such as zinc oxide or titanium dioxide, sit on the skin’s surface and reflect or scatter UV rays. Chemical sunscreens, on the other hand, absorb UV radiation and convert it into heat, which is then released from the skin. Both types are effective when used correctly and labeled “broad-spectrum,” meaning they protect against both UVA (aging) and UVB (burning) rays.
Skin cancer remains the most common cancer in the United States, yet it is also one of the most preventable. Incorporating a broad-spectrum sunscreen with SPF 30 or higher into your daily routine, along with protective clothing and annual skin exams, can significantly reduce your risk. “Skin cancer treatments are very effective, especially if we find the cancer early. According to the Skin Cancer Foundation, when melanoma is detected early, the five-year survival rate is 99 percent,” says Michael Housley, PA-C.
This Skin Cancer Awareness Month, Dermatology Clinic of Idaho encourages the Boise community to separate fact from fiction and make sun protection a daily priority.
