Lipstick, a cosmetic product designed to add color, texture, and protection to the lips, is not indefinitely stable. Like other beauty products, it is subject to degradation over time, leading to a decrease in performance and potential risks to the user. The period after which a lipstick is no longer considered suitable for use is a critical factor to consider.
Understanding the degradation timeline of lipsticks is vital for several reasons. Using expired products can result in diminished color payoff, altered texture, and a potential breeding ground for bacteria, increasing the risk of skin irritation or infection. Furthermore, the chemical composition can change, potentially leading to allergic reactions or other adverse effects. Historically, awareness of cosmetic product expiration dates has grown alongside increasing consumer understanding of product safety and hygiene.
