Check Your Sunscreen Before Applying

Sunscreens do expire. According to Mayo Clinic, sunscreens are "designed to remain at original strength for up to three years." This means you can use leftover sunscreen from the past few years.

Do you spot an expiration date on your sunscreen bottle? If you're past the date shown on the bottle, toss it before applying since they are no longer effective. Also, always store your sunscreen in a cool climate.
