4 Tips for Storing Sunscreen Properly

Keep sunscreen out of hot cars Temperatures above 80–90°F degrade chemical filters. A closed car can exceed 120°F in minutes, ruining the formula before you apply it.

Use mineral sunscreen for better heat tolerance Physical sunscreens hold up better in heat than chemical ones, but they still degrade over time.

Store at home in a dark cabinet Avoid windows and direct sunlight. A cool, dark place preserves effectiveness longer.

Keep sunscreen cool at the beach or pool Toss the bottle in your bag with a cold water bottle or keep it in the shade. Direct sun accelerates breakdown.
