fluorescent lamp for 1 h were shown in Fig. 8. It is very clear that
UV absorptions of CDBA-liposomes and avobenzone-liposomes
reduced significantly after UV irradiation for 3.5 h. And the
CDBA-liposome could recover its absorption ability after placed
under visible light for 1 h, while the avobenzone-liposome could
not recover. Therefore, CDBA-liposomes may have longer protection and longer shelf life.
