Health experts and regulatory bodies have highlighted the risks associated with using expired cosmetics, noting that products can become breeding grounds for bacteria as preservatives lose effectiveness. Potential health consequences include skin irritation, redness, stinging, and contact dermatitis, with individuals possessing sensitive skin or conditions like eczema facing higher risks.

Warning signs of deterioration include changes in aroma, such as rancid smells, as well as changes in texture like clumping or separation, and color shifts. To manage safety, European Regulation (EC) 1223/2009 requires manufacturers to provide expiration guidance, including minimum shelf life for unopened items and the Period After Opening (PAO) symbol, which indicates how many months a product remains safe after its initial use.
