Rapidly degrades under UV exposure losing significant UVA protection capacity unless stabilized by other filters.

Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.

Banned in several jurisdictions due to evidence of coral toxicity and accumulation in marine life.

Clinical trials demonstrate that single applications lead to blood concentrations vastly exceeding safety thresholds and remaining detectable for weeks [1.1].

Currently not approved by the United States FDA for use in sunscreens though it is widely approved in the EU and other global markets.

PEG compounds may contain trace amounts of 1,4 dioxane, a probable carcinogen, as a byproduct of the ethoxylation manufacturing process.

Because it is an ethoxylated ingredient, the manufacturing process can leave trace amounts of 1,4-dioxane and ethylene oxide, which are potential carcinogens.

Cyclopentasiloxane is restricted in the European Union to a maximum of 0.1 percent in leave on cosmetics by June 2027 due to environmental accumulation concerns.

Recognized as a frequent cause of allergic contact dermatitis especially in individuals with eczema or compromised skin barriers.

Squalene derived from shark liver is prohibited in cosmetics under European Union regulations due to environmental and animal conservation concerns requiring the use of plant derived alternatives.

Generally well tolerated but can cause contact dermatitis or skin irritation in rare cases, particularly in sensitive individuals.

Historically rated as mildly comedogenic in animal models but modern dermatological consensus indicates it is unlikely to clog pores in typical cosmetic formulations.

Named Contact Allergen of the Year in 2017 due to increasing reports of allergic contact dermatitis, though it remains safe and mild for the vast majority of users.

Pure ascorbic acid is notoriously unstable and oxidizes rapidly upon exposure to air heat and light which reduces its efficacy and can lead to skin irritation.

Contains high levels of oleic acid and typically scores a 3 to 4 on the comedogenic scale making it likely to clog pores and exacerbate breakouts in acne prone individuals [2.4].

Widely recognized as highly comedogenic with a maximum rating of 5 out of 5, meaning it is very likely to clog pores and trigger breakouts in acne-prone skin [1.6].

Poorly biodegradable in the environment and can accumulate in aquatic ecosystems where it may mobilize heavy metals.

Some animal studies suggest high oral doses may cause endocrine disruption, though regulatory bodies consider it safe at the low concentrations used in cosmetics.
