Why is Photostability Important? 1
Biggest Innovation in UVA Protection has Been the Invention of Avobenzone • Avobenzone provides broad spectrum beyond 370 nm 2. 5 With avobenzone Absorbance 2 1. 5 1 With oxybenzone 0. 5 0 290 310 330 350 370 390 Wavelength (nm) Data on file, Johnson & Johnson Neutrogena. 2

Why is Photostability Important? Photostable and non-photostable spf products have the same protection up to their SPF value, but protection after first MED is very different 4
How Can You Tell Which Ones Are Photostable? • Currently, there is no uniform test method or communication device on products to indicate photostability of products or extent of UVA protection 5
™ Helioplex Technology 6
What Comprises Helioplex™ Technology? • Photostable UVA – Contains avobenzone—provides broad UVA protection – Contains diethylhexyl 2, 6 -naphthalate (DEHN)— an avobenzone stabilizer – Contains benzophenone (oxybenzone, sulisobenzone, or dioxybenzone)—stabilizes avobenzone and adds UVA protection • Added SPF drivers – Conventional UV filters to build SPF Data on file, Johnson & Johnson Neutrogena. 7
