"As we speak, the ozone layer — which absorbs the most UV rays in the stratosphere — is depleting, meaning the Earth's natural protection is not enough anymore," says Dr. Frieling. "According to the CDC, skin cancer rates in the U.S. have doubled in the last 20 years, and it can be attributed to change in exposure risk factors. This includes indoor tanning and consistent unprotected overexposure to direct sunlight."

The moral of the story here is that sunscreen shouldn't be lumped into the "optional skincare" category. Consistent application is vital to our health and wellbeing. Though it may not offer instant gratification, over the years you'll thank yourself for being so diligent.
