Sunscreen is a vital tool for protecting our skin from harmful UV radiation, yet many misconceptions about its use persist. Whether it’s misunderstandings about SPF, application frequency, or environmental claims, misinformation can lead to inadequate sun protection. To help you stay safe in the sun, we’re debunking seven common sunscreen myths and setting the record straight.
Myth #1: SPF 30 Blocks Twice as Many UVB Rays as SPF 15 – Learn More with InfoCons Consumer Protection !
There’s a widespread belief that doubling the SPF number means doubling the level of protection. However, this isn’t the case. No sunscreen blocks 100% of UV rays, and the differences between SPF levels are smaller than many people think:
- SPF 15 filters out about 93% of UVB rays.
- SPF 30 blocks 97%.
- SPF 50 provides 98% protection.
While a higher SPF does offer slightly more protection, the key to effective sunscreen use is applying enough product and reapplying frequently.

Myth #2: SPF 50 Lasts Longer Than SPF 30 – InfoCons Consumers Protection Keeps You Informed !
Many people assume that SPF 50 sunscreen stays effective for longer than SPF 30, but that’s not true. Regardless of SPF rating, sunscreen should be reapplied every two hours when spending time outdoors. Additionally, you should always reapply after swimming, sweating, or toweling off to maintain protection.
Myth #3: ‘Reef-Safe’ or ‘Reef-Friendly’ Sunscreens Are Always Better for the Environment – InfoCons Consumer Protection Informs You !
With growing concerns about sunscreen’s impact on marine life, terms like “reef-safe” and “reef-friendly” have become popular. However, these labels are not regulated, meaning there’s little consistency in how they’re used. Some sunscreens labeled as reef-safe may still contain ingredients that could be harmful to marine ecosystems.
According to sunscreen expert John Staton, water-resistant sunscreens that meet Australian and New Zealand standards tend to be less harmful to coral reefs, as they are designed to adhere to the skin and minimize wash-off.

Myth #4: A Tan Protects You from Sunburn – InfoCons Consumers Protection Keeps You Informed !
Some people believe that getting a base tan reduces the risk of sunburn. In reality, a tan is a sign that skin damage has already begun. Further sun exposure only increases the damage, leading to premature aging, wrinkles, and an elevated risk of skin cancer. The best protection is consistent sunscreen use, along with wearing protective clothing and seeking shade.
Myth #5: Kids Need Special Sunscreen – Learn More with InfoCons Consumer Protection !
While sunscreens marketed for children often have gentler formulas, kids can safely use regular sunscreen as long as it doesn’t irritate their skin. To check for sensitivity, apply a small amount to a child’s forearm and wait a few days for any reaction.
Infants, however, have more delicate skin and should use mineral-based sunscreens with ingredients like zinc oxide or titanium dioxide. The best protection for babies and toddlers is to keep them in the shade and dress them in sun-protective clothing.

Myth #6: Sunscreen Causes Vitamin D Deficiency – InfoCons Consumers Protection Keeps You Informed !
Vitamin D is essential for bone health, and our bodies produce it when exposed to sunlight. However, concerns that sunscreen use leads to vitamin D deficiency are largely unfounded. Sunscreen acts as a filter, not a complete block, meaning that some UV rays still reach the skin.
According to dermatologists, people with fair skin can synthesize enough vitamin D in just a few minutes of midday sun exposure, even while wearing sunscreen. Those concerned about vitamin D levels should consult a doctor about diet or supplements.
Myth #7: You Don’t Need Sunscreen on Cloudy Days – Learn More with InfoCons Consumer Protection !
It’s a common mistake to skip sunscreen when it’s overcast, but up to 80% of UV rays can penetrate clouds. This means that even on cloudy days, your skin is still exposed to harmful radiation.
The UV Index (UVI) measures the intensity of UV radiation and can help determine when sun protection is necessary. When the UVI is 3 or higher, sunscreen is recommended. In some regions, UVI levels can exceed 12 during summer, making sun protection crucial year-round.
