How Can You Tell Which How Can You Tell Which Ones Are Photostable?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

What Comprises What Comprises HelioplexHelioplex™™ Technology? 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
