Did you know that skincare products, apart from having an expiry date, also come with a shelf life after you first open them? It's called the Period After Opening, or PAO for short. Unlike the expiry date, not all products display the PAO on their packaging. So, along with keeping an eye on the packaging condition and expiry date, let's dive into the world of PAO!
Cleanser
Cleansing products, whether facial soaps or initial cleansers, typically have one year's shelf life after breaking the seal. However, there are exceptions for facial soaps containing active ingredients like AHA, BHA, or salicylic acid, which usually have a shorter PAO of 6-8 months.
Toner
Hydrating toners can last about a year after opening if stored correctly. Since these toners offer hydration, keeping them in a cool place and shielded from direct sunlight is best. Exfoliating toners, on the other hand, have a shorter PAO due to their active ingredients.
Moisturizer
The PAO for moisturizers varies based on their packaging. Those in tube packaging can last up to a year because tubes are less prone to bacterial contamination. In contrast, moisturizers in jars, which require finger or spatula application, typically have a shorter lifespan of 6-11 months. Always ensure clean hands or a clean spatula when scooping the product.
Sunscreen
Sunscreen, a vital skincare and protection product, boasts one of the lengthiest PAOs, up to 1-2 years. However, proper storage is crucial. Store it in a cool place away from direct sunlight. Sunscreen's PAO may be less than a year if exposed to high temperatures.
Face Mask
Facial masks now come in various types. Organic masks, often in powder form, have a relatively short 1-4 months PAO due to the lack of preservatives and potential bacterial contamination. Clay masks, particularly in jar packaging, last around 7 months to a year, while tube-form masks offer a PAO of up to a year.
Skincare Pads
Skincare products in pad form, often containing active ingredients like peeling agents or moisturizers, have a PAO of approximately 2-5 months after opening.
Acne Spot Treatment
Acne spot treatments contain active ingredients to combat acne-causing bacteria, such as salicylic acid, sulfur, or benzoyl peroxide. Therefore, these products typically have a shorter PAO 6 months after opening.
Understanding the PAO for your skincare products is essential. For detailed information, you can contact customer service or the brand directly to ensure you make informed choices when purchasing and storing your skincare essentials!
