@Viss I'm doing the comparison:

Supergoop's only UVB blocking is the Homosalate 9%. Homosalate only covers smaller range of UVB with the best protection at 306nm. That's low, and we know it's not photostable and begins losing efficacy after 45 mins.

Products with Tinosorb are significantly more effective.

Look at the attached graph: HMS is Homosalate. It's the worst product on the market for UVB.
