Sunscreen Expiration: Understanding PAO Symbols and Shelf Life for Effective Protection
In a recent informative video, a representative from ISDIN clarified crucial details regarding the expiration of sunscreen products, a topic of significant interest for consumers prioritizing skin health. The expert, dressed in a lab coat, explained that, like many other cosmetic products, sunscreens do indeed expire. He demonstrated how to locate the explicit expiration date, often found on the product packaging. For products without a clear expiration date, the video highlighted the importance of the PAO (Period After Opening) symbol. This symbol, typically represented by an open jar icon with a number followed by 'M' (e.g., '12M'), indicates the number of months the product remains safe and effective for use after its first opening. The presenter emphasized that understanding these symbols is vital to ensure the continued efficacy of sun protection, preventing potential skin damage from expired or compromised formulas.
