- Human Fault: Most people apply merely 25-50 % of the recommended amount of sunblock, which significantly reduces the effective Sun Protection Factor (SPF).
- Uncomplete Coverage: It is easy to lose spots like the pinna, the upside of feet, or the area around the optic, leave those plot display to point UV light.
- Frequency of Covering: Sunscreen wears off due to sweat, water exposure, and clash from towels. If you do not reapply every two hours, your protection fade.

| SPF 30 | ~97 % | ~3 % |
| SPF 50 | ~98 % | ~2 % |

💡 Note: Remember to ensure the expiration appointment on your bottle. Over time, the chemical factor in sunscreen interrupt down and lose their effectiveness, providing you with a false sentience of protection.
The Truth About "Base Tans"
Many people believe in the myth of the "base tan", thinking that get a light-colored tan at the showtime of summertime will protect them from combust afterward on. Aesculapian experts powerfully advise against this. A tan provides merely a very minimal quantity of SPF (often less than SPF 3), which is nowhere near plenty to protect you from the intense UV exposure required to achieve that tan in the 1st property. Relying on a lowly tan rather of ordered sunscreen use is a dangerous scheme that importantly increases your long-term hazard of skin cancer and photoaging.
