The sun produces a great quantitiy of energy, which is transmitted by radiation of various types (see sidebar). When sun rays reach human skin, they interact with the epidermal cells. They are also able to interact with sun filters, which are substances applied on the skin to prevent sunburn and erythema. UV radiation, in particular, produces a high activation energy and induces a partial degradation or alteration process in a filter so that the filter reduces or loses its capacity for skin protection.1 This process is called photodegradation.
Photostability of Sun Filters Complexed in Phospholipids or Beta-Cyclodextrin

Abstract: Laboratory tests of three commonly used sun filters show that the filters encapsulated in beta-cyclodextrin show a photostability significantly higher than that of the same filters uncomplexed or complexed with phospholipids.
Z-COTE LSA provides broad-spectrum protection from long wave UVA rays and medium wave UVB rays by physically scattering, reflecting and absorbing solar radiation.
