Sunscreen is one of the most important steps in a skin care regimen because it blocks sun damage from occurring. A regular sunscreen application can help maintain healthy, youthful-looking skin and minimize wrinkles caused by sun exposure, which will help you look younger for longer.
Sunscreen is a key component of a skin care regimen, particularly for individuals who spend time outdoors. Applying sunscreen regularly to the skin can help prevent premature aging and inhibit cancer development.
Ultraviolet (UV) light from the sun is the primary cause of premature skin aging, known as photoaging. According to The Skin Cancer Foundation, unprotected exposure to UV rays causes 70 percent of all non-melanoma cancers and 90 percent of melanomas.
How to apply sunscreen
Applying sunscreen properly is important because it’s the number one cause of skin cancer. You can’t apply enough sunscreen to protect yourself from all UV rays. For that reason, experts recommend that you apply 30 minutes before going outside. To get protection from UVB rays, which cause sunburn and redness on the skin, and UVA rays, which contribute to wrinkles and skin cancer, you need to be in the sun for at least 15 minutes. Some people are more sensitive to UVA light than others. That’s why it’s vital to note the SPF number on the bottle and check it every time you use it.
Look at the expiration date and replace your sunscreen when necessary. Expiration dates are printed on sunscreen labels for a reason: Sunscreen can degrade over time, losing its effectiveness. The FDA requires sunscreen to have an expiration date of up to three years after manufacture; just remember that the SPF degrades over time as well. In addition, sunscreen with filters that absorb UVA and UVB rays is more effective and less likely to cause skin irritation than other types of sunscreen.
How often should you apply sunscreen?
If you’re going to be out in the sun for more than an hour, wear a broad-spectrum sunscreen that protects against both UVA rays (which cause premature aging) and UVB rays. The American Academy of Dermatology has created a chart listing recommended applications for various activities, as well as guidelines for reapplying sunscreen periodically.
