Common Sunscreen Ingredients

We all know and have heard a million times that sunscreen is the most essential part of one's skin care regimen. And if you do not have a skincare regimen, it is still an essential part of your daily routine. Listed are common sunscreen ingredients used, as well as those said to be most recommended by dermatologists.

Parsol 1789, also known as avobenzone, is a chemical sunscreen ingredient, meaning it absorbs UVA and UVB rays once they have hit the skin, thus protecting the skin from sun damage. Parsol 1789 is said to be a “broad spectrum” sunscreen additive and is commonly used due to its ability to absorb ultraviolet light over a wider range of wavelengths when compared to other sunscreen actives. Although Parsol 1789 is said to be a recommended sunscreen ingredient, it does break down easily, therefore should be formulated with a stabilizer.

Titanium dioxide, although used in many different products such as paint and dyes, is a very popular sunscreen ingredient. Titanium dioxide is UV resistant and a UV reflector, meaning that it prevents the sun's rays from reaching the skin and sends them back out in the environment. It is insoluble in water, therefore is commonly used in formulations to be water-resistant. Again, titanium dioxide is highly recommended among dermatologists.
