Is Avobenzone Safe on Skin?
Avobenzone is a popular ingredient you’ll find in many sunscreens. It’s great at absorbing those harmful UV rays, helping to keep your skin safe from sun damage. In 2019, the FDA published a report outlining concerns about the possible endocrine-disrupting effects of a common ingredient in UVA protectors. This led to a re-evaluation of the common sunscreen ingredient by numerous consumers.
Avobenzone in sunscreen is a topic that raises some safety concerns. Let’s examine the specifics:
Generally Considered Safe: Avobenzone is commonly recommended by dermatologists in sunscreens because it provides broad UVA protection, which is important for preventing premature aging and skin cancer.
In 1988, Avobenzone was approved by the FDA. However, it has since been surrounded by controversy. The issue arose in 2019 when the FDA report raised concerns about the potential for higher transdermal absorption of certain sunscreen active ingredients is greater than previously believed.
- Potential Concerns: Certain studies have raised questions about the absorption of avobenzone through the skin and its potential effects on hormones. In order to thoroughly evaluate this, the FDA is seeking additional data.
- Alternatives: Zinc oxide and titanium oxide mineral sunscreens are known for their non-absorbent properties, making them a safe choice for skin protection. However, they may lack the same aesthetic appeal as sunscreens containing avobenzone.
Here’s the takeaway: Although there are a few concerns regarding avobenzone, the majority of experts agree that it is safe to use. For added peace of mind, you may choose to use a mineral sunscreen instead. If you have any particular worries about sunscreen components, seeking advice from a dermatologist is recommended.
What is Avobenzone?
Avobenzone, which was developed in the early 1970s and approved by the FDA in the late 1980s, is a chemical sunscreen ingredients that helps protect the skin by absorbing UVA rays. Avobenzone absorbs harmful rays to protect the skin, unlike titanium dioxide and zinc which just reflect sunlight.
Avobenzone, found in the sunscreen, transformed harmful UVA rays into heat before releasing it as energy that is gentler on the skin. In simpler terms, Avobenzone changed UV rays into a form of energy that is safer for our skin. In order to provide broad spectrum UV protection, sunscreens containing Avobenzone are often combined with additional ingredients that filter out UVB rays. This combination ensures that the formula is effective in protecting against both UVA and UVB rays.
So Is Avobenzone Safe?
While there are concerns about avobenzone potentially being an endocrine disruptor, it is important to note that these concerns are currently based on speculation. Additional research is needed to confirm if avobenzone poses any risks.
The recent study by the American Academy of Dermatology shows that absorption of an ingredient into the bloodstream does not always mean it’s harmful. The text continues to explain how current knowledge shows that the dangers of not using sunscreen (specifically skin cancer) greatly outweigh any potential risks of using a product with avobenzone.
It is understandable to have concerns about avobenzone in relation to pregnant individuals. Due to restrictions on UV radiation testing on pregnant individuals, we are unable to manage scientific studies on the hormonal effects of avobenzone on them. Therefore, it is recommended to choose for mineral sunscreens that show no signs of absorption into the bloodstream. Mineral sunscreens are the ideal choice for children, particularly those who have not yet reached puberty, in order to prevent any potential hormone disruptions.
Are avobenzone sunscreens bad for all marine life?
Avobenzone is being criticized for its environmental impact, although its health concerns are currently uncertain. Research indicates potential harm to aquatic environments through toxicity and bioaccumulation.
Studies have shown that certain ingredients, such as avobenzone, may harm coral reefs, leading to growing concerns in recent times. Research conducted in laboratories may not always reflect real-life situations accurately. Nonetheless, Hawaii has banned the sale of sunscreens that contain avobenzone, oxybenzone, and octinoxate in the state.
So, avobenzone is a step up from some of those other chemical UV filters when it comes to being nice to coral reefs, but it’s not totally off the hook either. Researchers are still digging into how it might affect marine life in different ways. If you’re worried about how your sunscreen affects the planet, you might want to check out mineral-based options like non-nano zinc oxide and titanium dioxide, or even rock some UV-protective clothing.
Why is avobenzone used in sunscreen?
Avobenzone is considered safe in sunscreen due to its low toxicity, however, it reduces rapidly when exposed to sunlight. This means that when used alone, Avobenzone only offers approximately 30 minutes of protection.
In order to extend the duration of protection, manufacturers add harmful chemicals like octocrylene to many chemical sunscreens that contain Avobenzone. The inclusion of Octocrylene is beneficial for stabilizing Avobenzone; however, it is important to note that Octocrylene is an endocrine disruptor and is known to release free radicals. Skin samples revealed a higher presence of free radicals with the use of octocrylene compared to skin exposed to sunlight without any sunscreen protection.
Free radicals are unstable molecules that can cause damage to skin cells, increasing the likelihood of developing cancer and other health concerns. Consumers should be aware that sunscreens with Avobenzone have potential health risks. Knowing what Avobenzone is can help make an informed decision. Deciding to use a sunscreen with Avobenzone is a personal choice, but choosing a physical sunscreen may be preferred for those worried about endocrine disruptors or seeking an eco-friendly alternative.
The Benefits of Avobenzone in Sunscreen
Avobenzone is commonly found in many sunscreens due to its effectiveness. Here’s why it stands out:
- Broad-Spectrum Protection: Avobenzone stands out from other sunscreens by not only protecting against UVB rays that cause sunburn but also absorbing harmful UVA rays. UVA rays have the ability to penetrate deeply into the skin, which can result in premature aging and a higher likelihood of developing skin cancer. With avobenzone, you get a more thorough defense against the harmful effects of the sun.
- Effective UVA Absorber: Avobenzone stands out as an extremely effective UVA blocker. It plays a vital role in ensuring that broad-spectrum sunscreens are able to achieve a high SPF (Sun Protection Factor) rating.
- Lightweight and Sheer: Avobenzone, a chemical sunscreen ingredient, works by absorbing UV rays instead of forming a layer on the skin like mineral-based sunscreens. As a result, sunscreens containing avobenzone tend to feel lighter and less oily when applied to the skin.
However, there are ongoing investigations into potential drawbacks related with avobenzone that need to be considered:
- Stability: Sunlight can weaken avobenzone over time, reducing its effectiveness. Look for sunscreens that combine avobenzone with stabilizing ingredients.
- Potential Allergic Reactions: Although rare, a few individuals might encounter skin inflammation due to avobenzone.
In combination with other sunscreen ingredients, avobenzone provides good sun protection benefits. If you have any worries about using avobenzone, it’s best to seek advice from a dermatologist to find the most suitable sunscreen for your needs.
