Sun exposure leads to wrinkles and uneven pigmentation by damaging the dermis of the skin and is also blamed for skin cancers.
Why Sunscreen is Important for skin?
Sunscreens play an important role in a total program to reduce the harmful effects of the sun, along with limiting sun exposure and wearing protective clothing. FDA regulates sunscreens as over-the-counter (OTC) drugs. Cosmetic products that are marketed with sun-protection claims are regulated as both drugs and cosmetics.
Gone are the days when we basked in the sun or at least without first applying sunscreen. In our youth we tried various ways to darken our skin and lighten our hair with the power of the sun. Skin cancer kills more than 10,000 people per year, according to an article published by the FDA. There are three main types of skin cancer.
Sunscreens will lower your risk of skin cancer and protect your skin from looking weathered and aged before its time.
Studies show that UV light causes DNA mutations to occur in the skin. These mutations lead to cancer. Exposure to the sun thickens the skin and a tan is a sign of sun-injury. Sunscreen can protect the skin from these harmful effects. It’s important to prevent sunburns in order to maintain healthy, youthful skin.
Sunscreens should be applied to dry skin 15 to 30 minutes before going outdoors. Don’t forget to protect the ears, neck and along the hairline as well as the lips. Sunscreens should be reapplied approximately every two hours or after swimming or perspiring heavily. The effectiveness of a sunscreen is reduced if it is not applied in adequate amounts or it is washed off, rubbed off, sweated off, or otherwise removed. For maximum effectiveness, apply a sunscreen liberally and reapply it frequently. If you’re a parent, protect your children’s skin because skin cancer does not have an age requirement; it affects people of all ages.
Finding products mixed with sunscreen have become increasingly available. For example, many beauty products, such as foundation and even hair spray, have included minimum amounts of SPF sunscreen to combat dangerous UV rays. There also are sunscreens made for specific purposes, such as sensitive skin and for use on babies.
Sunscreen can be in your foundation or moisturizer and it will help to prevent new wrinkles from developing and existing ones from getting deeper.
Beauty products (such as foundation) should also contain sunscreen throughout the year. UV rays can still peek through those cloudy winter days and damage the skin, even if there is no visible sunshine present. The face needs the most protection because the skin is thinner and prone to high levels of sun damage.
Ideally, sunscreens should be water-resistant, so they cannot be easily removed by sweating or swimming, and should have an SPF of 30 or higher that provides broad-spectrum coverage against both UVA and UVB light.
