does multani mitti expire

Multani mitti, also known as Fuller’s Earth, doesn’t have an official expiration date like perishable goods, but that doesn’t mean it lasts indefinitely without any risk of changes in quality. Like most natural products, its efficacy can diminish over time, and exposure to certain conditions can cause it to degrade. The changes in color you’re noticing could indicate it has been exposed to moisture or contaminants, which can affect its performance and potentially cause skin irritation. If it smells off or the texture has changed (e.g., it’s clumping or feels less smooth), it’s safer to replace it. The general advice is to keep it in an airtight container in a cool, dry place, to minimize degradation. Although there’s no strict timeline, many people find it remains effective for up to a year if properly stored. If you’ve had it for several months without any issues but are starting to notice differences now, that’s a sign it might be time to get a fresh supply. Using outdated products may not only reduce their effectiveness but potentially increase the risk of skin reactions, especially if impurities have been introduced. It’s understandable to want to avoid waste, but when it comes to your skin, erring on the side of caution is wise. Wouldn’t hurt to conduct a patch test next time if you suspect any changes.
