Sunscreen does expire. The molecules in suntan lotion (such as homosalate and octyl salicylate) block the penetration of UV radiation by acting as filters and absorbing and reflecting high energy UV.

When picking up your EpiPens at the pharmacy, you should open the package to ensure that the expiration date is at least a year out. Sometimes the pharmacy will give you one that is near itâs expiration date by accident. You should also keep in mind that the liquid within the EpiPen should be clear. If it is cloudy or discolored, you should properly dispose of it. Always keep your EpiPen out of extreme temperaturesâhot or cold.
