Chemical Sunscreen

Allows UV light into the skin. Once the light is absorbed, the chemicals in the sunscreen create a reaction in which UV light is converted to heat and dissipates from the skin. The typical chemicals you will find are: oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate. You will also typically find parabens, phthalates, synthetic fragrances, nonparticles, and more.

Mineral Sunscreen

Uses zinc oxide and titanium dioxide, which sit on the skin's surface and physically prevents UV rays from penetrating the skin. This is the "safer" option of the two. It is not absorbed into the skin like the chemicals in “typical” sunscreen, and usually doesn’t contain all the unnecessary and toxic additives mentioned above.

A note on Titanium Dioxide

TiO₂ is often discussed in safety conversations, so it’s worth clarifying. Current evidence suggests that it does not penetrate intact, healthy skin and is not associated with systemic or localized harm when applied topically (Campaign for Safe Cosmetics).

Regulatory bodies, including the European Commission’s Scientific Committee on Consumer Safety, have identified titanium dioxide as a possible category 2 carcinogen when inhaled. This classification is specific to inhalation exposure, such as from loose powders or aerosolized products, rather than skin application.

In cream-based formulations, titanium dioxide has not been shown to pose the same concerns. However, for the purpose of this review, only zinc oxide-based options have been included.

A note on Butyloctyl Salicylate

Many sunscreens, especially spray formulas, contain butyloctyl salicylate. This ingredient is commonly used to improve spreadability and help boost SPF performance. It belongs to the salicylate family and is structurally similar to some chemical UV filters, although it is not classified as an active sunscreen ingredient itself.

Some research and safety databases note concerns such as potential skin absorption, low-level hormone activity, and effects on aquatic life. Because it is part of the salicylate family, some experts recommend caution during pregnancy, although research on long-term health effects is still limited and not conclusive.
