Can I Use Expired Skincare?

Can I Use Expired Skincare? — it is generally not recommended, because ingredients can degrade, lose effectiveness, or become more likely to harbor bacteria after their expiration or period-after-opening date. Active ingredients and sunscreens in particular may no longer perform reliably once expired.

Key points

• Expiration and period-after-opening (PAO) dates indicate when a product is expected to remain stable and safe.
• Active ingredients such as vitamin C, retinoids, and SPF filters can lose potency over time.
• Expired products may develop changes in color, texture, or smell that signal degradation.
• Using old products carries a higher risk of irritation or contamination, especially around the eyes.
• Storing products away from heat and light helps them last through their intended shelf life.
