Ethylhexyl Methoxycrylene
A sunscreen helper that stops filters like avobenzone breaking down in sunlight. What’s known about it comes from lab tests.
What it does
It takes extra energy from filters like avobenzone and octinoxate and lets it off as heat, so they keep working. The SPF comes from the main filters; this helps it hold in the hours after you apply.
