![]() This means some studies have suggested that sunscreens with this ingredient potentially could impact fertility, onset of puberty and more.Īdditionally, studies have shown BP-3 and other chemical sunscreen ingredients may cause contact dermatitis and allergic reactions. Oxybenzone (BP-3) is at the top of the concern list, along with octinoxate (OMC), because studies have linked these chemicals to hormone disruption. If oxybenzone isn't banned, why should we consider avoiding it? Our constant exposure to and high absorption of sunscreen chemicals is raising health concerns, especially because there is not enough safety data for many sunscreen ingredients. Pro tip: To err on the side of caution, stick with GRASE sunscreen ingredients. Most sunscreens commonly found on shelves (other than mineral-based sunscreens) have at least one of these active ingredients. ![]() This means additional data is needed to show that these sunscreens are GRASE. The remaining 12 chemical ingredients, namely oxybenzone (BP-3 or benzophenone-3), octinoxate (OMC or octyl methoxycinnamate), cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octisalate, octocrylene, padimate O, sulisobenzone and avobenzone, fall into this category. This and trolamine salicylate are no longer allowed as sunscreens. When applied topically, para-aminobenzoic acid (PABA), an intermediate in the synthesis of folate by bacteria in the gut, may cause some individuals to have allergic skin reactions. They are reef-safe, and they protect your skin by reflecting harmful UV light away from your body. GRASE sunscreens are physical barriers that sit on top of your skin and are not absorbed into the bloodstream. This acronym stands for "Generally Recognized as Safe and Effective." The mineral sunscreens, namely titanium dioxide and zinc oxide, fall into this category. In 2019, the FDA sorted the 16 active ingredients found in most sunscreens into three categories: Most of the active chemical ingredients in sunscreens are under scrutiny, and the Food and Drug Administration has called for more testing. What ingredients are potentially harmful in sunscreen? Many broad-spectrum sunscreens have more than one active ingredient, including ingredients like octisalate, octocrylene and homosalate along with the avobenzone or oxybenzone in their formulas. These ingredients act as UV filters either by physically blocking UV rays, which is how mineral sunscreens work, or by absorbing UV rays and releasing them back out as heat energy, which is the way chemical sunscreens do their job.īoth mineral and chemical sunscreens may have the label "broad spectrum," which means they protect you from radiation from the two main types of ultraviolet rays associated with skin cancer and aging: UVA and UVAB. Sunscreens can be mineral (zinc oxide or titanium dioxide) or chemical (such as avobenzone, octinoxate, oxybenzone and others). What are the different types of sunscreens? And if you're using a product every day, it's particularly important to choose one that's safe and effective. So daily use of sunscreen is one of the best and easiest ways to protect your skin's appearance and health. It can also cause inflammation, cellular changes and oxidative stress that weakens the immune system, and those bright rays can also damage your eyes. UV rays can cause premature aging and contribute to the development of skin cancers, like melanoma. While those warm rays of sunshine may feel fine on your face, they don't do your skin any favors. If this sounds like an important job, it is. Sunscreen products act as physical and chemical UV filters that help block ultraviolet radiation-known as UV rays-from the sun. We're here to shine some light on sun protection and help you choose the sunscreen type that will work best for you. Myths and misinformation about the benefits and the dangers of UV exposure and sunscreen continue to cast a haze on our relationship with the sun. ![]() But even though the sun is reliable, our information about it isn't. If there's one thing we can count on, it is that the sun will rise in the east tomorrow and a new day will dawn. ![]()
