Understanding the Context
Why does sunscreen expire is gaining attention in the US
The debate about sunscreen expiration is not a new phenomenon. However, recent trends suggest that consumers are becoming more aware of the importance of sunscreen efficacy and the potential risks associated with expired products. The rise of online forums and social media platforms has created a space for individuals to share their concerns and experiences with sunscreen expiration.

How does sunscreen expire actually work
So, what happens when sunscreen expires? In simple terms, expiration refers to the point at which the sunscreen's effectiveness diminishes, leaving it less capable of protecting your skin from the sun's harsh rays. Sunscreen expiration is primarily due to the degradation of active ingredients, such as oxybenzone and avobenzone, which break down over time due to exposure to heat, light, and oxygen. This degradation can lead to a decrease in the sunscreen's ability to absorb and reflect UV radiation, rendering it less effective in preventing sunburn and skin damage.
