4 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

5 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

7 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.
