Not only is sunscreen needed to prevent sunburns and skin cancer, but it’s also the most effective product you can use to prevent premature signs of aging. Overexposed to the sun and tanning can cause wrinkles, especially on your face, chest, hands.

Even if you have a sunscreen that you apply daily, it’s important to know what ingredients are in it. Some cheaper products contain chemicals that will do more harm than good for your skin.

Board-certified cosmetic dermatologist Dr. Karyn Grossman says Oxybenzone and Octinoxate are a “drugstore ingredient no-no.”

These ingredients are very common chemical filters that can be found in many commercial chemical sunscreens at the drugstore. They are used to absorb UV light but research has shown that they penetrate the skin and can disrupt hormones.

Instead, Dr. Karyn Grossman recommends using products that contain ingredients like Titanium Dioxide and Zinc Oxide for sun protection.

Sunscreen still remains the most important weapon in preventing premature skin aging and skin cancer.
