What is Avobenzone?

Base containing avobenzone.

Avobenzone is a chemical sun protection ingredient also known as Parsol 1789 or butyl methoxydibenzoylmethane that was introduced to the skin care market in 1981. It is one of the few sunscreens, along with titanium oxide, zinc oxide and Mexoryl SX, that offers full spectrum UVA protection from sun damage. In addition to being an active ingredient in sunscreen formulas, avobenzone can also be found in other skin and body products, including hand creams, moisturizers and makeup bases.

The sun is the source of UVA and UVB rays, which can cause damage to the skin.

While many sunscreens provide protection against UVB rays, the solar radiation that causes sunburn and contributes to skin cancer, they do not always provide adequate protection against UVA rays, which penetrate deeper into the skin and contribute to skin aging. and also for cancer. Avobenzone provides this protection and is often combined with sunscreens, such as octyl methoxycinnamate, which blocks UVB radiation, in cosmetic and sunscreen formulas. Avobenzone differs from zinc oxide and titanium oxide in that it is a chemical sunscreen that absorbs radiation before it can damage the skin. Zinc oxide and titanium are physical sunscreens that actually reflect the sun’s rays off the skin, rather than absorbing them.

A broad-spectrum sunscreen that contains avobenzone works to block UVA rays.

There has been some controversy over the use of avobenzone, as some have argued that it degrades in sunlight, compromising its usefulness as a sunscreen. Some of these researchers have suggested that avobenzone can be modified or combined with other ingredients to make it more stable. Other experts claim that other studies show that avobenzone is a stable ingredient that has proven its effectiveness over decades of use. Individuals who have a preference for one type of sunscreen over another should read product labels carefully to discern which ingredients are used in a specific formula.

Avobenzone is an active ingredient in some sunscreen formulas, which can help prevent sunburn.

The American Academy of Dermatology recommends that people use a sunscreen that provides protection against a broad spectrum of the sun’s rays, and that sunscreen should have a sun protection factor (SPF) of at least 15. The American Academy of Dermatology recommends yet sunscreen is applied daily, not just when someone goes to the beach or an outdoor event, then reapplied every two hours to all parts of the body that are exposed to the sun. Other skin care experts, including medical staff at the University of California, San Francisco School of Medicine, advise using sunscreens with an SPF of at least 30.
