Higher SPF Doesn’t Always Mean Better Protection, Say Experts

The warmer months have returned, marking the onset of sunscreen season, which serves as a timely reminder that sun protection is essential year-round. Dermatologists emphasise the need for consistent sunscreen application, noting that repeated sun exposure accumulates over time, impacting skin health and appearance as individuals age. Dr. Shannon Humphrey, a board-certified dermatologist, explains that the damage from ultraviolet radiation is cumulative, with much of the harm evident later in life as a result of years of exposure.

As people grow older, the focus on skincare evolves, transitioning from merely preventing sunburn to addressing cumulative sun damage that leads to wrinkles, dark spots, and even skin cancer. Experts agree that using sunscreen need not be overly complicated; regular use is one of the best practices for maintaining skin health.

Common mistakes in sunscreen application include the misconception that higher SPF equates to better protection. Dr. Humphrey indicates that the most effective sunscreen is one that users apply consistently, preferably a broad-spectrum formulation that defends against both UVA and UVB rays. Additionally, it is critical to apply a sufficient quantity — around a quarter teaspoon for the face and approximately one ounce for the body — as most individuals under-apply, significantly reducing the stated protection.

Failing to reapply sunscreen is another frequent error. Claire O’Bryan, a nurse practitioner, points out that many people believe a single morning application offers all-day protection, which is incorrect. Experts recommend reapplying every two hours, particularly after swimming or sweating, while also covering high-risk areas often overlooked, such as the ears and neck.

Lastly, using expired sunscreen poses risks, as products degrade over time and can lose their effectiveness. To ensure adequate protection, individuals should select a broad-spectrum sunscreen with an SPF of 30 or higher, apply generously, reapply regularly, and incorporate it into their daily routines.
