Outdated and Outlawed: Why Traditional UV Filters Are No Longer Enough
The Problem with Traditional UV Filters
For decades, traditional UV filters like Avobenzone (Wksorb980), Octocrylene, Homosalate, and Benzophenone have been widely used in sunscreens. hile effective at the time, scientific research has revealed several serious drawbacks:
For decades, traditional UV filters like Avobenzone (Wksorb980), Octocrylene, Homosalate, and Benzophenone have been widely used in sunscreens. hile effective at the time, scientific research has revealed several serious drawbacks:
Key Limitations:
- Photoinstability: Many degrade under sunlight, losing effectiveness over time and requiring stabilizers or reapplication.
- Skin Absorption: Small molecular sizes enable them to penetrate the skin and enter the bloodstream, triggering health and safety concerns.
- Endocrine Disruption: Some filters are linked to hormonal interference and potential reproductive health effects.
- Environmental Impact: They can harm marine life and coral reefs. Regions like Hawaii, Palau, and Thailand have banned filters such as:
- Benzophenone-3 (Oxybenzone)
- EHMC (Ethylhexyl Methoxycinnamate)
- 4-Methylbenzylidene Camphor (4MBC)
- Butylparaben
These limitations have fueled a global shift toward safer, more sustainable alternatives.
