As a sommelier and brewer, I can understand the importance of using products within their recommended time frame for optimal results. When it comes to skincare products like The Ordinary, it is generally advisable to adhere to the recommended PAO (period after opening) guidelines mentioned on the packaging.
The PAO symbol, usually represented by a number followed by the letter “M” (months), indicates the recommended duration for using the product after opening. It serves as a guideline to ensure the product's effectiveness and safety. The numbers can vary, such as 3m, 6m, 9m, or 12m, depending on the product.
While it may be tempting to use a product beyond its expiration date, it is generally not recommended. The expiration date is there for a reason, as it indicates the point at which the product may start to degrade or lose its efficacy. Using a product beyond its expiration date can result in reduced effectiveness and potentially even adverse effects on your skin.
However, it is important to note that some products may have a longer shelf life than others, depending on their formulation and ingredients. For instance, products with active ingredients like retinol or antioxidants may have a shorter shelf life compared to products without these ingredients. So, it is always a good idea to check the specific PAO information for each product.
To keep track of the opening date and ensure you use the product within the recommended time frame, you can write the date of opening on the box or bottle. This simple step can help you avoid using expired products and ensure you get the most out of your skincare routine.
In my personal experience, I have found that following the recommended PAO guidelines has been beneficial. It gives me the confidence that I am using the product at its peak performance, and I can see the desired results on my skin. Additionally, it also allows me to rotate and incorporate new products into my skincare routine without any concerns about using expired ones.
It is advisable to use The Ordinary products within their recommended PAO period after opening. This ensures optimal effectiveness and minimizes the risk of adverse effects. By paying attention to the expiration dates and using the products within the specified time frame, you can make the most of your skincare routine and achieve the desired results.
