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.
Ethylhexyl Triazone is an oil-soluble organic UV filter that strongly absorbs UVB radiation (peak around 314 nm), valued for its high photostability and efficiency at low concentrations. It is commonly used in sunscreens and daily-wear products to boost SPF.
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (also known as Bemotrizinol or Tinosorb S) is a broad-spectrum organic UV filter that absorbs both UVA and UVB radiation. It is highly photostable and is commonly used in sunscreens and daytime skincare products to provide photoprotection.
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.
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%.
Thermus Thermophillus Ferment is a fermentation-derived ingredient obtained from a thermophilic (heat-loving) bacterium, used in skincare primarily for its antioxidant properties and purported ability to enhance skin's resistance to environmental and thermal stress. It is often included for its protective and conditioning effects rather than as a primary corrective active.
