Octyl Methoxycinnamate (Octinoxate) is a widely used organic UVB filter that absorbs ultraviolet radiation to protect skin from sunburn and photodamage. It is commonly incorporated into sunscreens and daily-care products with SPF claims.
Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations.
Diethylhexyl Butamido Triazone (Iscotrizinol, Uvasorb HEB) is an organic, oil-soluble UVB filter that absorbs ultraviolet radiation primarily in the UVB range, providing photoprotection in sunscreen and daily-care formulations. It is highly photostable and substantive to skin, often combined with other filters for broad-spectrum coverage.
Diethylamino Hydroxybenzoyl Hexyl Benzoate (also known as Uvinul A Plus) is an oil-soluble organic UV filter that absorbs primarily in the long-wave UVA range (around 354 nm), helping protect skin from UVA-induced damage. It is photostable and commonly combined with other filters in broad-spectrum sunscreens.
Niacinamide (vitamin B3) is a water-soluble active that supports the skin barrier, regulates sebum, brightens hyperpigmentation, and reduces inflammation. It is widely tolerated across skin types and used in concentrations commonly ranging from 2% to 10%.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
