Earlier this year, the FDA approved Anthelios SX, an over-the-counter product that contains a camphor derivative (ecamsule/Mexoryl SX), which is photostable and targets UVA radiation. In addition, Neutrogena has added a stabilizer, Helioplex, to several of its products containing avobenzone and other UVA blockers, which might boost their efficacy in protecting against a spectrum of UVA wavelengths.
