Highly effective vesicular compositions from UV-absorbing lipids are described in the present invention. Combination of UV-absorbing property and the vesicular delivery system results in higher levels of photoprotection to skin and hair. The vesicular compositions of the present invention are made from cationic UV-absorbing lipids of Formula I wherein,
ArCO is selected from cinnamoyl, p-methoxy cinnamoyl, p-N,N-dimethylamino benzoyl and combinations thereof, R
1
is selected from saturated or unsaturated alkyl group with carbons ranging from C
10
to C
