Sunscreen is an important part of a beauty regimen. It protects the skin from spotting and wrinkling, as well as skin cancer.

However, many people don’t use sunscreen correctly.

There are mistakes that prevent getting the protective benefits of sunscreen, and also that don’t increase it:

• Not reapplying: Most people put on sunscreen in the morning. By the time night rolls around, that application is long gone. Reapply throughout the day.

• Layering products to increase SPF: Some people think that they are getting extra protection by combining sunscreen with SPF make-up—that a moisturizer of SPF 15 mixed with a sunscreen that is a SPF 45 equals a protection of SPF 60. It’s just an SPF of 45; the higher SPF wins out.

• Only using sunscreen in make-up: The SPF found in most make-up is simply not high enough to protect the skin in direct sunlight.
