Products

The ‘best before’ date on cosmetics indicates the period during which the product is expected to remain at optimal quality, though it is not always a strict expiration date. Consumers should check for the Period After Opening (PAO) symbol—usually shown as an open jar with a number (e.g., 6M, 12M)—which tells how long the product remains safe and effective after being opened. To maintain product integrity, cosmetics should be stored in cool, dry places away from direct sunlight and heat. Expired products, even if they appear normal, can degrade and cause skin irritation, infections, or lose effectiveness. Users should monitor for changes in color, texture, or smell, as these may indicate spoilage. It is also helpful to label products with the opening date to track usage time. Following the manufacturer's storage and usage guidelines is essential, especially for products that contain fewer preservatives or natural oils, which may spoil more quickly. Sharing cosmetics should be avoided to reduce contamination risks, and care should be taken to keep the pipette or applicator away from the skin to avoid introducing bacteria into the product.
