Consider purchasing a sunscreen that protects against both UVA and UVB wavelengths.
For adequate protection, use a sunscreen with a sun protection factor (SPF) of 30 or higher.
Apply sunscreen every two hours, or more frequently if swimming or significantly perspiring.
Before going outside, apply sunscreen at least 15 to 30 minutes beforehand to enable it to fully absorb into the skin.
Apply sunscreen to all exposed skin, such as the face, neck, ears, limbs, and legs.
Utilize alternative precautions such as seeking shade, donning protective clothing, and wearing sunglasses.
Pay attention to areas that are often neglected, such as the back of the neck, the tops of the ankles, and the ears.
Verify the sunscreen's expiration date and avoid using it if it has passed.
Even water-resistant sunscreen will fade off after swimming or perspiring, so reapplication is necessary.
