However, Hawaii has banned this ingredient after a study, created by the Haereticus Environmental lab, found that the ingredient contributed to bleaching and poisoning coral reefs. Most recently, a study found that our skin absorbs sunscreen ingredients like oxybenzone. Combined with avobenzone, they can both provide great broad-spectrum protection against burns and aging.
This ingredient is allowed in formulations up to 7. On its own, the ingredient destabilizes when exposed to light. In the U. However, researchers also write that power and spray forms should be avoided as it may be hazardous. It can also be found in SPF makeup, pressed powders, lotions, and whitening products.
In Europe, the ingredient is labeled with a warning because of its toxicity to aquatic life. Also known as para-aminobenzoic acid, this is a strong UVB absorber.
The popularity of this ingredient has decreased due to the fact that it increases allergic dermatitis and increases photosensitivity.
Studies on animals have also shown certain levels of toxicity, leading the European Commission and the FDA to restrict formula concentrations to 5 percent. The drug classification comes because the product is marketed as a preventive measure for sunburn as well as skin cancer.
In Australia, sunscreen is classified as therapeutic or cosmetic. July 22, Twitter Facebook. The good news is that safe and effective sunscreen options are available. All you want to know is what sunscreen ingredients are safe and effective. What does SPF even mean? How do you know what SPF you need?
Does higher SPF matter? What is broad-spectrum sunscreen? What the difference between sunscreen and sunblock? Okay, then what are the best sunscreen ingredients? Zinc oxide, oxybenzone, octinoxate and associates: the good, the bad and the environmentally unfriendly. Do you have sensitive skin? Avoid oxybenzone. Are you going to be in or near water that supports a coral reef?
Avoid oxybenzone, octinoxate, zinc oxide Are you breastfeeding or planning to donate blood? The currently available sunscreens in the United States are safe and active, and the benefit in protecting the skin from harmful UV rays outweighs any perceived risk to our health. Holly Thaggard, the San Antonio, Texas—based founder and CEO of Supergoop , the first high-end skincare brand to make SPF its focus, says both mineral and chemical sunscreens can be right for you depending on your skin type.
These are great for daily wear, multiple skin tones, the beach, and working out. Mineral sunscreens are made up of tiny white, UV-protecting particles — zinc oxide, titanium dioxide, or both — and are more gentle, perfect for anyone with sensitive or acne-prone skin.
Thaggard agrees that mineral sunscreens are not as wearable, and must be formulated carefully to ensure that they are stable and effective, but that both options are viable. While a study published in May in JAMA has raised concern about how quickly some SPF products are absorbed into the skin, Zeichner says these studies were based on tests in which people covered 75 percent of their body with sunscreen every two hours.
If anyone is concerned with the use of chemical blocker sunscreens, mineral options that contain zinc oxide alone or in combination with titanium dioxide are a great option. A follow-up FDA study, published in JAMA in January , analyzed six active sunscreen ingredients avobenzone, oxybenzone, octocrylene, homosalate, octisalate, and octinoxate.
Along with maximal, every-two-hour use, researchers also looked at skin absorption from a single application and found that some of these ingredients remain detectable in the body for up to 21 days. The research only looked at if these ingredients were absorbed and how long they remained in the body, not if they caused harm.
The recommendation to wear sunscreen as directed stands. While it helps achieve high SPF ratings, it is also widely known as being one of the most irritating raw ingredients to work with, as opposed to the alternative, much more skin-compatible, and noncontroversial avobenzone, which is essential for getting a broad-spectrum clean chemical sunscreen.
It's important to remember that UVA rays are present throughout the year at about the same intensity, even when it's cloudy or through windows. This way, you can most easily avoid falling for confusing marketing ploys on sunscreen bottles.
Skip the fancy packaging, colors, logos, etc. This is an essential property of the sunscreen and one that you should always look for when choosing a product.
UVB rays are responsible for causing the characteristic red sunburn and causing cellular damage that leads to skin cancer. UVA rays penetrate deeper into the skin where the collage resides and are the leading cause of skin aging from the sun. In addition to this important label, you want to see that the product is broad-spectrum to avoid the harmful effects of UVA rays as well.
Very water-resistant means it will hold up after 80 minutes of water immersion testing. This testing is conducted in an indoor, freshwater pool. The subject is immersed in water in minute intervals up to 40 minutes or 80 minutes with a minute rest out of water in between each interval. During this 15 minute rest, the subject does NOT towel off to dry. It is very important to understand how this is tested in order to interpret these claims in a real-life setting such as the salt-water ocean at the beach or in a chlorinated pool or hot tub.
Because these products are not tested in various water conditions and most people do towel off when getting out of the water, it is unlikely that these water-resistant products are as protective as the research shows.
This can be achieved with added components such as waxes, oils, or polymers like dimethicone. These can potentially change how the sunscreen feels on the skin and can be a bit thicker to rub in. The same recommendations for reapplication apply to sunscreens in this category. All water-resistant and very water-resistant products must be reapplied every 2 hours or when getting out of the water.
It also offers the easiest way to ensure you are applying enough of the product to be effective. I highly recommend sunscreens in creams and lotions compared to all other vehicles. Gels can be drying, so it is best to avoid this type of sunscreen on dry or irritated skin. Sprays: Although sunscreen sprays are typically the easiest to apply of all the formulations, they are the LEAST effective! Therefore, I never recommend using sunscreen sprays.
It is difficult to know if you are spraying enough on to the skin to be effective. If a spray is going to be used, it is preferred to spray the product onto the palm and then apply it to the skin.
However, this tip effectively eliminates the purpose of a spray. I tell patients to never use these on the face due to the risk of inhalation. And these should never be used in babies or children as it is harder for these age groups to hold their breath during application which further increases their risk of inhalation. Sticks: Sunscreen sticks are particularly useful for around the eyes, the backs of the hands, and hard to reach spots.
These products can be effective if applied in several passes over the skin. To improve their efficacy, I recommend rubbing it in after application. These are great for on-the-go and traveling.
They are listed on the back of the sunscreen product in alphabetical order.
