 | | 5 / 7 5. Using expired beauty products
Do you keep track of the use-by dates of your makeup and skincare products? Most women haven't a clue. Which spells bad news, because these are things you apply directly on your face. Products past their shelf life can become ineffective or worse, harbor bacteria that can potentially trigger an infection or breakout. Mascaras, for example, should be discarded 6 months after opening. Retinoids and AHAs are effective for 3 months to a year, while antioxidant skincare with vitamin C lasts 6 months. If you are using preservative-free products, you should be extra vigilant as these have a much shorter shelf life.
