Trisiloxane
Ingredient Info
Drometrizole trisiloxane is a UV filter used in sunscreens to protect skin from harmful ultraviolet radiation. It's a newer chemical sunscreen ingredient that offers broad-spectrum protection and is widely used in international markets, though not yet approved in the U.S.
Benefits
- Provides broad-spectrum UV protection against UVA and UVB rays
- More photostable than some older UV filters, maintaining effectiveness longer
- Newer alternative to older chemical sunscreen ingredients with potentially better safety profiles
Potential concerns
- Allergic contact dermatitis has been reported in some individuals
- May cross-react with sensitivities to other sunscreen chemicals
- Not yet FDA-approved in the U.S., so long-term safety data in American populations is limited
Science: Drometrizole trisiloxane is used internationally and has demonstrated favorable safety and efficacy profiles in global markets. However, documented cases of allergic contact dermatitis exist in the scientific literature, indicating it may not be suitable for all skin types. As a newer filter, it has less extensive long-term safety data compared to established UV filters like zinc oxide or titanium dioxide.
