The effect of Avobenzone in sunscreen

May. 30, 2024

Avobenzone is a common ingredient in chemical sunscreens. Unlike other chemical sunscreens that only protect against UVB rays that cause sunburn, Avobenzone also protects skin from UVA rays, rays that cause premature aging and skin cancer.

1. What is Avobenzone?

Invented in 1973 and approved by the FDA in 1988, Avobenzone is a chemical sunscreen ingredient that helps protect skin from harmful rays through absorbing UVA rays. This is unlike chemical sunscreen ingredients like titanium dioxide and zinc, which sit on top and deflect the sun's rays.
Instead, the Avobenzone in the sunscreen converted the UVA rays into heat and then released it as heat energy. In other words, Avobenzone converted UV rays into energy that is less harmful to the skin. Also, because it doesn't filter out UVB rays, Avobenzone in sunscreens is often combined with ingredients that filter UVB rays to give these products broad spectrum UV protection - meaning the formula helps protects against both UVA and UVB rays.

2. The effect of Avobenzone in sunscreen

Avobenzone itself in sunscreen is relatively safe in terms of toxicity, but this ingredient breaks down quickly in the sun. Once exposed to the sun, Avobenzone alone provides only about 30 minutes of protection. So while many chemical sunscreens still use Avobenzoneto protect skin from UVA rays, manufacturers then have to add unsafe chemicals like octocrylene to make the cream's action time longer. longer than 30 minutes. The added Octocrylene helps stabilize Avobenzone, which is fine, but it's an endocrine disruptor that also releases free radicals. Skin sample tests showed more free radicals with octocrylene than with sun-exposed skin without sunscreen. It is these free radicals that can damage skin cells and increase the risk of cancer and other health problems. Therefore, using products containing Avobenzone in sunscreens may have potential health risks that consumers need to understand what Avobenzone is to make the right choice. Accordingly, choosing to use a sunscreen containing this ingredient depends on personal preference, but if you are concerned about the potential for endocrine disruptors or want a more eco-friendly option, choose physical sunscreen instead.

3. Alternatives to avobenzone in sunscreen

Free radicals formed in the skin when using sunscreens containing Avobenzone are a health hazard. This risk also needs to be weighed against the benefits of using sunscreen to prevent premature skin aging and skin cancer.
Fortunately, alternatives to Avobenzone in sunscreen such as zinc oxide can provide natural broad-spectrum sun protection. Zinc is an inert ingredient, does not decompose in the sun and does not release free radicals, so it is safe for the skin.

In summary, Avobenzone in chemical sunscreens is one of the basic ingredients to protect the skin from the effects of UV rays. However, compared to physical sunscreens, these products may have potential risk factors for the skin due to the free radicals generated. Accordingly, consumers need to know what the properties of Avobenzone are to make the right choice, especially when choosing to buy from reputable manufacturers.
There are natural, broad-spectrum sunscreen products on the market that contain safe ingredients, helping users confidently apply sunscreen every day to keep their skin optimally protected. These products have an optimal and durable sunscreen filter in the sun, protecting the skin from the harmful effects of both UVA and UVB rays with the highest level of protection. In addition, some sunscreen products also have outstanding advantages with a light, smooth, creamy texture that stays on the skin for a long time, helping to soften and smooth the skin and help brighten the skin tone, not causing oil shine, insoluble in water. water, providing effective protection against UV rays all day long.
