Best and Worst Sunscreen Ingredients

You know you need to apply sunscreen every day to protect against damage from the sun’s harmful UV rays. You may even be an individual that dutifully applies sunscreen before heading outside no matter what season it is. However, there are some ingredients in sunscreens that could be doing more harm than good. We’ve rounded up a list of the very worst sunscreen ingredients that you should avoid at all costs, and their counterparts, the very best and beneficial sunscreen ingredients.

Worst Sunscreen Ingredients

Chemical formula of Oxybenzone

Oxybenzone
Oxybenzone is almost always number one of the list of ingredients you should be avoiding when it comes to your sunscreen. This ingredient is in your sunscreen because it is a chemical that helps other chemicals penetrate the skin more effectively. However, while it does help other ingredients penetrate the skin, it also absorbs into the skin and can create allergic reactions or eczema-like symptoms. Unfortunately, that isn’t the worst of what oxybenzone does. Skin care experts and doctors believe that oxybenzone circulates in your system and mimics, blocks and changes the level of hormones in your body.

Octinoxate
This is one of the most common ingredients in sunscreen and like oxybenzone, it helps other chemicals be absorbed by your skin. Unlike oxybenzone, octinoxate is rarely a cause of allergic reactions, but it is still a dangerous ingredient. Most people wear sun protection in order to prevent signs of premature aging, but octinoxate may enhance premature aging as it creates free radicals. Additionally, octinoxate is another sunscreen ingredient that disrupts the hormone levels in the body.

Chemical formula of  Retinyl Palmitate

Retinyl Palmitate
Also known as Vitamin A, this ingredient is an antioxidant added to sunscreens. And while antioxidants are generally great for your skin, there is a major problem when it comes to retinyl palmitate. When this antioxidant is exposed to the sun, it breaks down and creates dangerous free radicals. Free radicals are destructive and may be linked to cancer as they are toxic to cells and damage your DNA. In fact, studies conducted by the Food and Drug Administration suggest that retinyl palmitate can accelerate the development of malignant cells and skin tumors.

Best Sunscreen Ingredients

Zinc Oxide
Zinc oxide is a common ingredient in physical sunscreens. It is an inorganic compound that protects mainly against UVA rays. When used in a sunscreen, zinc oxide is a very finely milled powder and famously results in the white cast that physical sunscreens often leave.

Titanium Dioxide
Titanium dioxide is the other most common ingredient in physical sunscreens. It is also widely used in the cosmetic industry and has a variety of uses. The reason that titanium dioxide is most helpful in sunscreens is that it actually absorbs UV rays produced by the sun. It is a highly stable sunscreen ingredient that helps your skin remain protected from the sun.

It does not matter if you prefer physical or chemical sunscreen, but it should be worn before exposing yourself to the sun. When reading ingredients be sure to avoid the worst ingredients to keep yourself as healthy as possible. If using  chemical sunscreen be sure to apply 20 minutes prior to sun exposure and reapply every two hours or after immersing yourself in water. And, of course don’t forget to enjoy the sunshine (safely!).
