Understanding Cosmetic Expiration and PAO Symbols
Khaosod Online provides guidance on identifying cosmetic shelf life through expiration dates and the Period After Opening (PAO) symbol.
Many consumers mistakenly believe that cosmetics do not expire or that refrigeration can indefinitely extend their usability. According to a report by Khaosod Online, all cosmetic products, including skincare and makeup, have a limited lifespan that begins to degrade once the packaging is opened. Contamination from hands or application tools can further accelerate this deterioration.
To ensure product safety and efficacy, consumers are advised to check packaging for two key indicators: the standard expiration date and the Period After Opening (PAO) symbol. The PAO symbol, typically depicted as an open jar icon with a number, indicates how many months a product remains safe to use after it is first unsealed.
Signs that a product should be discarded include noticeable changes in color, unusual odors, or separation of ingredients, even if the expiration date has not yet passed. For residents and travelers in Thailand, paying attention to these labels is essential for maintaining skin health and avoiding potential irritation caused by degraded formulas. While these guidelines help in managing personal care items, consumers should always prioritize product integrity over attempting to use items past their recommended duration. Further details on specific product storage requirements should be verified with individual manufacturers.
